NEW QUESTION # 60
An HPE Aruba NetworkingCX switch administrator wants to monitor all inter-switch connections and change their descriptions dynamically with Python scriptand NAE engine. The administratorhas written the script template and uploaded it to the switch GUI. After the upload, not all data is stored as planned.
Which things should be checked first? (Select three.]
- A. monitor usage
- B. Agent usage
- C. memory usage
- D. scriptusage
- E. processor usage
- F. flash memory usage
Answer: A,B,D
Explanation:
An NAE (Network Analytics Engine) Python script designed to monitor links and update descriptions isn't storing data as planned. We need the first things to check (select three).
* NAE Components & Troubleshooting:NAE involves Agents running Scripts, often triggered by Monitors observing system state (like interface status or LLDP changes). Failures can occur in any component or due to resource issues.
* Initial Checks:
* Script (script usage - C):Check the script itself for syntax errors, logic flaws, status, and logs (show nae script <name> [status|log]). Ensure it's uploaded correctly and enabled.
* Agent (Agent usage - B):Check the agent configured to run the script. Is it running? Are its parameters correct? Are there errors associated with the agent? (show nae agent [status|detail]).
Check agent resource limits.
* Monitor (monitor usage - E):If the script relies on a monitor to trigger or gather data, check the monitor's status, configuration, and associated conditions (show nae monitor [status|detail]). Is the monitor detecting the intended events?
* Resources (Processor/Memory/Flash - D, F, A):General switch health is important. High CPU (D) or memory (F) usage could prevent the script/agent from running correctly. If the script is supposed to store datapersistently (e.g., write to a file or NAE database), check flash memory usage (A) or NAE database limits.
* Conclusion:When troubleshooting NAE, the core components to check first are the Script itself (C), the Agent running it (B), and any Monitors it depends on (E). These cover the specific NAE elements involved. General system resources (D, F, A) are secondary checks if the core components appear configured correctly but still fail.

NEW QUESTION # 62
Refer to the exhibit.
The customer has VSX clusters in two locations interconnected over an MC-LAG interface.
If active-gateway configuration uses the same virtual IP address and vMAC on each of the VSX nodes, what must you take into consideration?
- A. The configuration would end up in an async setup.
- B. Outbound traffic will be load-balanced over all VSX members for each session.
- C. Transit traffic will increase over the VSX interconnected MC-LAG.
- D. Each ARP request will result in four responses.
Answer: D
Explanation:
With the same anycast gateway (virtual IP and vMAC) configured on both VSX clusters across the L2 MC-LAG interconnect, an ARP request for the gateway is seen by all four VSX nodes.
Since each node is configured to respond with the same vMAC, the client will receive multiple (four) ARP replies.
NEW QUESTION # 63
Refer to the exhibit.
Acme Corp has VM workload running downstream of ToR-1 and has noticed performance degradation. They suspect ToR-1 uplinks are periodically overutilized. A partner has suggested you migrate your legacy 1U Core-1 and Core-2 to the CX 6400 series.
Which aspects of this platform would solve the customer's problem, while focusing on implementing HPE Aruba Networking best practices? (Choose two.)
- A. The proposed new core's VSF capability allows multiple active forwarding pathways from ToR-1 based while eliminating the need for STP.
- B. MC-LAG permits Core-1 and Core-2 to present the edge 802.3ad device as a common "system ID".
- C. The proposed solutions backplane stacking permits the directly connected ESXI hosts to load balance using active LACP.
- D. The port density of the CX 6400 series chassis permits the direct connection of the VM hypervisors to the core.
- E. The CX 6400 series supports multiple active forwarding pathways from ToR-1 based on multi- region design.
Answer: A,B
Explanation:
Moving to CX 6400 with VSX/MC-LAG lets Core-1 and Core-2 appear as a single LACP partner (common system ID) to ToR-1. This enables active-active uplinks and balances traffic across both cores, reducing uplink overutilization.
Using a multi-chassis/stacked core eliminates blocked STP links so ToR-1 has multiple active forwarding paths, further improving utilization and resiliency.
NEW QUESTION # 64
A senior engineer from the network operations team has reported an intermittent problem where some PoE- powered devices are randomly losing power. During your investigation, you found that port 1 of the Acc-1 switch is currently presenting the behavior shown in the CLI output for the Acc-1.
What is a probablecausa lot poor 1/1/1 is denying PoE?
- A. PoE port priority sot to low
- B. This switch does no! support PoE class 4.
- C. PoE was manually disabled for port 1/1/1.
- D. switch PoE powerbudget exceeded
Answer: D
Explanation:
The question involves intermittent PoE-powered device power loss on port 1/1/1 of an AOS-CX switch (Acc-
1), with CLI output (not provided) indicating a PoE issue. The task is to identify a probable cause.
* Analysis of Options:
* Option A:Incorrect. AOS-CX switches typically support PoE Class 4 (802.3at, 30W), sufficient for most devices.
* Option B:Correct. If the switch's PoE power budget is exceeded, it may deny power to port 1/1
/1, causing intermittent device failures.
* Option C:Incorrect. Low PoE port priority may deprioritize the port but is less likely to cause complete power loss compared to budget issues.
* Option D:Incorrect. Manual disabling of PoE would cause consistent power loss, not intermittent issues.
* Why Option B is Correct:AOS-CX switches have a finite PoE power budget (e.g., 370W or 740W, depending on the model and power supply). If the total power demand from connected devices exceeds this budget, the switch denies power to some ports, often intermittently as devices cycle or negotiate power. For port 1/1/1, this could manifest as random power loss for the connected device. The CLI output likely shows a "power denied" status (e.g., via show power-over-ethernet brief). Checking the PoE budget (show power-over-ethernet) and upgrading power supplies or prioritizing critical ports resolves the issue, aligning with HPE Aruba Networking's PoE troubleshooting guidelines.
* Relevance to Certification Objectives:
* Connectivity (9%):Troubleshooting PoE deployment issues.
* Troubleshooting (10%):Diagnosing power-related issues in campus networks.
* Switching (19%):Implementing PoE configurations for Layer 2 devices.

NEW QUESTION # 65
Refer to the exhibits.
An engineer has applied the above configuration to R1 and R2, however, the router's OSPF adjacency never progresses past the "EXSTART/DR" state.
Which configuration action on either router will allow R1 and R2 to progress past the
"EXTART/DR" state?
- A. Remove the L3 MTU configuration.
- B. Ensure the OSPF process is not configured with passive-interface default.
- C. Change R1 and R2 to a network type of point-to-point.
- D. Change the IP address and mask applied to interface 1/1/1 to a valid mask supported by RFC
2328.
Answer: C
Explanation:
The OSPF adjacency is stuck in the EXSTART/DR state because the broadcast network type is being used by default on the /31 link. On a /31 point-to-point link, OSPF neighbors should not attempt DR/BDR election. Changing the OSPF network type to point-to-point on either R1 or R2 ensures correct adjacency formation and allows the routers to progress to the FULL state.
NEW QUESTION # 66
Match the AOS-CX switch BGP keepalive and holddown timersto the default.
Answer:
Explanation:
Explanation:
The question requires matching the default BGP keepalive and hold-down timers on AOS-CX switches to their respective values.
* Analysis of Options:
* Keepalive Timer:The keepalive timer determines how often BGP keepalive messages are sent to maintain a session. The default value on AOS-CX switches is 60 seconds.
* Hold-down Timer:The hold-down timer specifies the maximum time a BGP session can remain active without receiving a keepalive or updatemessage before it is considered down. The default value on AOS-CX switches is 180 seconds.
* Why This Mapping is Correct:Per BGP standards (RFC 4271) and HPE Aruba Networking AOS-CX documentation, the default BGP keepalive timer is 60 seconds, and the hold-down timer is 180 seconds (three times the keepalive interval). These timers ensure BGP sessions remain stable while allowing timely detection of peer failures. The AOS-CX implementation adheres to these defaults unless explicitly configured otherwise.
* Relevance to Certification Objectives:
* Routing (16%):Involves designing and troubleshooting BGP routing topologies, including timer configurations.
* Troubleshooting (10%):Includes diagnosing BGP session issues related to timers.

NEW QUESTION # 67
A bgp routing table contains multiple routes to the same destination prefix. Referring to the table below, which route would be marked with a ">" symbol?
- A. C
- B. D
- C. A
- D. B
Answer: B
Explanation:
BGP path selection follows attributes in order. First, Local Preference is checked: routes B, C, and D all have 100 (better than route A with 0). Next, Origin Code is compared: "i" (IGP) is preferred over "?" (incomplete), so route B is less preferred. Between C and D, the MED is compared (lower is better). Route D has MED 0, route C has MED 20. Thus, Route D wins and is marked with ">".
NEW QUESTION # 68
Refer to the exhibit.
During the update of the aggregation switches, Acc-1 clients were not able to receive multicast traffic for a few seconds. How can you improve the downtime for multicast traffic to a minimum time?
- A. Change multicast routing protocol from PIM-SM to PIM-DM.
- B. Enable config-sync multicast at the VSX command context.
- C. Configure VSX active forwarding on Agg-1 and Agg-2 switches.
- D. Enable PIM active-active feature on both Agg-1 and Agg-2.
Answer: D
Explanation:
In a VSX environment, only one aggregation switch (Agg-1) is the PIM-SM Designated Router (DR) and IGMP querier. During an upgrade, when Agg-1 is unavailable, multicast traffic forwarding fails until Agg-2 takes over. By enabling the PIM active-active feature on both Agg-1 and Agg-2, multicast forwarding becomes synchronized and seamless across both devices, reducing downtime to the minimum.
NEW QUESTION # 69
Refer to thefour numbered steps in theexhibit.
Which action is the first step in applying a role-to-role ACL on thetraffic from mobile device M1 to role H2?
- A. The edge switch acts as the intermediate node and transfers theGroup Policy ID over static VXLAN to dynamic VXLAN tunnel and forwards the packet to switch A1.
- B. Gateway 1 forwards the traffic over the static VXLAN tunnel to the edge switch, this packet carries the Group Policy ID corresponding to the role of M1.
- C. The AP forwards the pocket from M1 to gateway 1.
- D. Switch A1 determines the destination role based on destination MAC or destination IP and enforces role-to-role ACLs.
Answer: C
Explanation:
The question asks for the first step in applying a role-to-role ACL (Access Control List) on traffic from a mobile device (M1) to a role (H2) in a network using Dynamic Segmentation with VXLAN and role-based policies.
* Analysis of Options:
* Option A:Describes an intermediate step where the edge switch transfers the Group Policy ID over VXLAN, which occurs later in the process.
* Option B:Correct. The first step is the AP forwarding the packet from the mobile device (M1) to the gateway, which initiates the traffic flow in a tunneled Dynamic Segmentation setup.
* Option C:Describes a later step where the destination switch (A1) enforces the role-to-role ACL, after the packet has traversed the network.
* Option D:Describes a step where the gateway forwards traffic over a VXLAN tunnel, which occurs after the AP forwards the packet.
* Why Option B is Correct:In HPE Aruba Networking's Dynamic Segmentation architecture, wireless clients (e.g., M1) connect to an AP, which tunnels traffic to a gateway (e.g., in tunneled mode). The first step in the traffic flow is the AP forwarding the client's packet to the gateway, which then processes the packet for role assignment and policy enforcement. This aligns with the role-to-role ACL application process, where the gateway applies policies based on the source (M1's role) and destination (H2's role) using Group Policy IDs over VXLAN.

* Security (10%):Involves designing and troubleshooting role-based security policies in customer networks.
* WLAN (9%):Includes implementing and troubleshooting wireless traffic flows in Dynamic Segmentation.
* Switching (19%):Covers Layer 2/3 interconnection technologies like VXLAN for policy enforcement.

NEW QUESTION # 70
Match each BGP element to its description.
Answer:
Explanation:
Explanation:
This question requires matching BGP protocol elements (mostly message types) to their primary function or description.
* OPEN Message:This is the first message sent after the TCP connection is established between BGP peers. Routers exchange OPEN messages to negotiate session parameters (AS Number, Hold Time, Router ID, Capabilities). A successful exchange leads to session establishment.
* Matches:"sets up and establishes BGP adjacency"
* UPDATE Message:This message is used to communicate network reachability information (NLRI). It carries prefixes that are being advertised, path attributes associated with those prefixes, and/or prefixes that are being withdrawn.
* Matches:"advertises, updates, or withdraws routes"
* KEEPALIVE Message:These messages are sent periodically between BGP peers within the agreed- upon Hold Time interval. Their primary purpose is to confirm that the peer is still alive and the session is active, especially when there are no UPDATE messages to send.
* Matches:"ensures that BGP peers are still alive"
* NOTIFICATION Message:This message is sent when a BGP error condition is detected (e.g., malformed message, unacceptable parameters in an OPEN message, hold timer expiry). Sending or receiving a NOTIFICATION message immediately causes the BGP session to terminate.
* Matches:"indicates error condition to a BGP neighbor"
* Route Refresh:This is a BGP capability (defined in RFC 2918) that allows a BGP speaker to request its peer to resend its routing updates for a specific address family, typically used after a policy change without requiring a full BGP session reset.
* Matches:"request a BGP peer to resend updated messages"
References:RFC 4271 (BGP4 Specification - Section 4, Messages), RFC 2918 (BGP Route Refresh Capability). This relates to the "Routing" (16%) objective.
NEW QUESTION # 71
You have recently configured a switch for 802.1X authentication with HPE Aruba Networking ClearPass. A security admin is seeing events with the following description in ClearPass Event Viewer.
'RADIUS authentication attempt from unknown NAD (10.10.1.10:1812)'
Which command should you use to identify the configuration issue?
- A. show aaa authentication-server radius
- B. show radius-server detail
- C. show ip source-interface radius
- D. show radius-server shared-secret
Answer: B
Explanation:
show radius-server detail will display the configured RADIUS servers along with their IP addresses and shared secrets. This helps you verify if the switch's management IP is properly registered as a NAD (Network Access Device) in ClearPass. If the IP used by the switch to send RADIUS requests is not listed as a NAD in ClearPass, you will see the "unknown NAD" error.
NEW QUESTION # 72

- B.
- C.
- D.
Answer: A
Explanation:
The question involves configuring an OSPF virtual link to extend area 0 across a non-backbone area, based on an exhibit (not provided) and four configuration options (A to D). Since the exhibit is unavailable, I will assume a typical scenario where a virtual link is needed to connect two area 0 segments through a transit area (e.g., area 1).
* Analysis of Options (Assumed Context):A virtual link is configured using the area <transit-area> virtual-link <router-id> command in the OSPF process. The correct option likely includes:
* Option A:Incorrect syntax or incorrect router ID/area for the virtual link.
* Option B:Incorrect configuration, possibly missing the virtual link or using wrong parameters.
* Option C:Correct. Likely includes the proper command, e.g., area 1 virtual-link 2.2.2.2, where area 1 is the transit area and 2.2.2.2 is the router ID of the remote ABR.
* Option D:Incorrect, possibly configuring an unnecessary or incorrect virtual link.
* Why Option C is Correct:OSPF requires all areas to connect to the backbone area (area 0). If two area
0 segments are separated by a non-backbone area (e.g., area 1), a virtual link is configured between the Area Border Routers (ABRs) to logically extend area 0 through the transit area. The command area
<transit-area> virtual-link <remote-router-id> is used, specifying the transit area and the router ID of the remote ABR. Option C is assumed to provide the correct syntax and parameters based on standard OSPF virtual link configurations, ensuring area 0 connectivity and proper route advertisement.
* Relevance to Certification Objectives:
* Routing (16%):Designing and troubleshooting OSPF topologies, including virtual links.
* Troubleshooting (10%):Resolving OSPF area connectivity issues.

NEW QUESTION # 73
You are implementing a network using Zero-Touch Provisioning (ZTP) to deploy the gateways.
What are two requirements for the connection to the switchport? (Choose two.)
- A. The switchport needs to be untagged with Internet access
- B. Jumbo frames must be enabled
- C. The gateway needs to be provided an IP address through DHCP
- D. You must use port GE 0/0/1 on the gateway
- E. The switchport needs to be configured with IP address 172.16.0.254
Answer: A,C
Explanation:
For Zero-Touch Provisioning (ZTP), the gateway must connect to a switchport with untagged Internet access so it can reach Aruba Central or the provisioning server. Additionally, the gateway requires an IP address via DHCP, which provides the necessary network configuration (IP, DNS, default gateway, and optionally ZTP server URL). No specific physical port, static IP, or jumbo frame configuration is required.
NEW QUESTION # 74
Which commands will permit read-only access to a user with physical access to an AOS-CX switch?
- A.
- B.
- C.
- D.
Answer: B
Explanation:
To provide read-only access, the user must be assigned to the read-only group, not operators.
This ensures the user has local authentication and is restricted to read-only commands when accessing the switch console.
NEW QUESTION # 75
A client installed 655 APs in a project to upgrade the network in a large public venue. The customer states that they are having issues with the integration with the new sensor system (Bluetooth) that will help the facilities team monitor when the venue is in the use.
What could be the issue?
- A. throughput
- B. PoE
- C. Bluetooth needs an advanced AP license.
- D. AP-655 does not have Bluetooth radio
Answer: D
Explanation:
The issue is that the AP-655 model does not include a built-in Bluetooth radio. Since the customer's integration relies on Bluetooth for the sensor system, the absence of this hardware capability prevents the solution from functioning as intended.
NEW QUESTION # 76
Exhibit.
After Implementing a distributed overlay with distributed anycast gateways, you noticed that toomany ARP packets are being replicated to every access (leaf) switch Which command can you use to optimize the network?
- A. vlan 10 arp-suppression vlan 11 arp-suppression
- B. evpn arp-suppression
- C. evpn ip proxy-arp
- D. interface vlan 10 ip proxy-arp interface vlan 11 ip proxy-arp
Answer: B
Explanation:
In an EVPN VXLAN distributed overlay network, excessive ARP packet replication (flooding) to all leaf switches is observed. We need the command to optimize this.
* EVPN ARP Optimization:EVPN uses its control plane (BGP) to distribute MAC and IP address reachability information. Leaf switches (VTEPs) learn these mappings. To reduce ARP flooding across the VXLAN fabric:
* ARP Suppression:VTEPs intercept ARP requests. If the VTEP already knows the MAC address for the requested IP (learned via EVPN), it can suppress the ARP request, preventing it from being flooded over VXLAN.
* Proxy ARP:VTEPs intercept ARP requests. If the VTEP knows the MAC for the requested IP, it can generate an ARP replyon behalfof the remote host.
* AOS-CX Commands:These features are configured within the EVPN context.
* evpn arp-suppression (B): Enables the ARP suppression feature for EVPN.
* evpn ip proxy-arp (C): Enables the proxy ARP feature for EVPN.
* Options A and D use standard interface/VLAN level arp-suppression or proxy-arp commands, which are not specific to optimizing flooding within the EVPN VXLAN fabric itself.
* Conclusion:To optimize by reducing the replication/flooding of ARP packets across the EVPN VXLAN overlay, enabling evpn arp-suppression (Option B) is the direct command. This leverages the EVPN control plane knowledge to stop unnecessary ARP flooding.
References:AOS-CX EVPN Configuration Guide (ARP Suppression, Proxy ARP features). This relates to
"Switching" (19%) and "Routing" (16%) objectives in the context of overlays.

NEW QUESTION # 78
A pair of CX 8325 series switches a configured in a VSX cluster. Which function is executed on both VSX members during normal operation?
- A. periodically sends gratuitous ARP and broadcast hello packets
- B. replies to ARP requests with thecluster vMAC
- C. relays DHCP requests or serves DHCP offer
- D. routes PIM and PIM-DR
Answer: B
Explanation:
The question asks which function is executed on both VSX members (CX 8325 switches) during normal operation in a VSX cluster.
* Analysis of Options:
* Option A:Correct. Both VSX switches reply to ARP requests with the cluster's virtual MAC (vMAC) for SVIs configured with active-gateway, ensuring consistent Layer 3 forwarding.
* Option B:Incorrect. PIM (Protocol Independent Multicast) and PIM-DR roles are typically handled by one switch, not both, in a VSX cluster.
* Option C:Incorrect. DHCP relay or server functions are not necessarily performed by both switches simultaneously.
* Option D:Incorrect. Gratuitous ARP and broadcast hello packets are typically sent by the primary switch or specific protocols, not both VSX members for all cases.
* Why Option A is Correct:In a VSX cluster, the active-gateway feature allows both switches to respond to ARP requests for Switched Virtual Interfaces (SVIs) using a shared virtual MAC address (vMAC). This ensures seamless Layer 3 forwarding and high availability, as clients receive consistent ARP replies regardless of which VSX switch processes the request. The vsx-sync feature ensures the vMAC is synchronized, enabling both switches to perform this function during normal operation, as per HPE Aruba Networking's VSX architecture.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Designing and troubleshooting VSX for redundancy and active-active forwarding.
* Switching (19%):Implementing Layer 2/3 technologies, including ARP handling in VSX.
* Routing (16%):Ensuring consistent Layer 3 operations in VSX environments.

NEW QUESTION # 79
An IT administrator uses AOS-CX switches to send TCP 22 trafficfrom the switch port to a remoteserver for analysis. The administrator now wants to save it locally tobedownloaded and used later in case the admin changes their mind about the approach to take.
- A. destination cpu
- B. destination file tshatk-pcap
- C. destination tunnel file tshark-pcpap
- D. destination flash:/.'my-mirror.pcnap policy Policy Minor22
Answer: B
Explanation:
The question involves an AOS-CX switch administrator using a packet capture (e.g., tshark) to monitor TCP port 22 traffic and wanting to save it locally for later download, instead of sending it to a remote server.
* Analysis of Options:
* Option A:Correct. The destination file tshark-pcap command specifies that the packet capture output is saved to a local file (e.g., tshark-pcap) on the switch's flash storage.
* Option B:Incorrect. destination tunnel file tshark-pcpap is not a valid AOS-CX command for local storage.
* Option C:Incorrect. destination cpu is not relevant for saving packet captures; it may refer to CPU-based monitoring.
* Option D:Incorrect. destination flash:/.'my-mirror.pcnap policy Policy Minor22 has invalid syntax and does not align with packet capture storage.
* Why Option A is Correct:In AOS-CX, packet captures can be configured using the monitor command (e.g., monitor session 1 source interface 1/1/1 destination file tshark-pcap). The destination file tshark- pcap option saves the captured packets (e.g., TCP port 22 traffic) to a local file on the switch's flash storage, which can be downloaded later via SCP, SFTP, or the Web UI. This meets the administrator's requirement to store the capture locally for future analysis, aligning with AOS-CX's packet capture capabilities.
* Relevance to Certification Objectives:
* Troubleshooting (10%):Performing advanced troubleshooting using packet captures.
* Performance Optimization (6%):Analyzing network traffic for performance issues.
* Connectivity (9%):Diagnosing connectivity issues with monitoring tools.

You plan to replace a customer's old network equipment on AGG-SW1 and AGG-SW2 with CX
8325 in VSX and Edge-1 with CX 6200F. The customer's old network equipment is configured with industry-standard protocols. You want to migrate the gateway functionality that would be supported with the old equipment for a seamless failover.
Which first-hop protocol can you use?
- A. Configure the VSX SVI using active-forwarding and vMAC matching the existing MAC.
- B. Configure the VSX SVI using the VRRP matching VRID and virtual-ip.
- C. Configure the VSX SVI using the active-gateway and vMAC matching the existing MAC.
- D. Configure the VSX SVI using the unicast IP address and vMAC.
Answer: B
Explanation:
Since the old network equipment is using industry-standard protocols for first-hop redundancy, the correct migration path is to configure the new CX 8325 VSX pair with VRRP, matching the same VRID and virtual IP. This ensures seamless interoperability and failover without requiring proprietary features like VSX active-gateway.
