NEW QUESTION # 23
Your network uses a single JSA host and you want to implement a cluster.
In this scenario, which two statements are correct? (Choose two.)
- A. The software versions on both primary and secondary hosts
- B. The primary and secondary hosts must be configured with the same storage devices.
- C. The cluster virtual IP will need an unused IP address assigned.
- D. The secondary host can backup multiple JSA primary hosts.
Answer: A,C
Explanation:
According to the Juniper Networks JNCIP-SEC Study Guide, when setting up a cluster with a single JSA host, both the primary and secondary hosts must have the same software version installed. Additionally, an unused IP address must be assigned to the cluster virtual IP. The primary and secondary hosts do not need to be configured with the same storage devices, and the secondary host cannot be used to backup multiple JSA primary hosts.

NEW QUESTION # 26
A client has attempted communication with a known command-and-control server and it has reached the configured threat level threshold.
Which feed will the clients IP address be automatically added to in this situation?
- A. the custom cloud feed
- B. the infected host cloud feed
- C. the command-and-control cloud feed
- D. the allowlist and blocklist feed
Answer: B
Explanation:
Infected hosts are internal hosts that have been compromised by malware and are communicating with external C&C servers3. Juniper ATP Cloud provides infected host feeds that list internal IP addresses or subnets of infected hosts along with a threat level3. Once the Juniper ATP Cloud global threshold for an infected host is met, that host is added to the infected host feed and assigned a threat level of 10 by the cloud4. You can also configure your SRX Series device to block traffic from these IP addresses using security policies4.
NEW QUESTION # 27
Which three statements about SRX Series device chassis clusters are true? (Choose three.)
- A. Chassis cluster control links must be configured using RFC 1918 IP addresses.
- B. Heartbeat messages verify that the chassis cluster control link is working.
- C. Chassis cluster member devices synchronize configuration using the control link.
- D. Recovery from a control link failure requires that the secondary member device be rebooted.
- E. A control link failure causes the secondary cluster node to be disabled.
Answer: B,C,E
Explanation:
1. Chassis cluster member devices synchronize configuration using the control link: This statement is correct because the control link is used for configuration synchronization among other functions.
2. A control link failure causes the secondary cluster node to be disabled: This statement is correct because a control link failure causes the secondary node to become ineligible for primary role and remain in secondary role until the control link is restored.
3. Heartbeat messages verify that the chassis cluster control link is working: This statement is correct because heartbeat messages are sent periodically over the control link to monitor its status.

NEW QUESTION # 30
Which statement regarding Juniper Identity Management Service (JIMS) domain PC probes is true?
- A. JIMS domain PC probes are initiated by an SRX Series device to verify authentication table information.
- B. JIMS domain PC probes are triggered to map usernames to group membership information.
- C. JIMS domain PC probes are triggered if no username to IP address mapping is found in the domain security event log.
- D. JIMS domain PC probes analyze domain controller security event logs at60-mmute intervals by default.
Answer: C
Explanation:
Juniper Identity Management Service (JIMS) domain PC probes are used to map usernames to IP addresses in the domain security event log. This allows for the SRX Series device to verify authentication table information, such as group membership. The probes are triggered whenever a username to IP address mapping is not found in the domain security event log. By default, the probes are executed at 60-minute intervals.
NEW QUESTION # 31
You want to permit access to an application but block application sub-Which two security policy features provide this capability? (Choose two.)
- A. URL filtering
- B. APPID
- C. micro application detection
- D. content filtering
Answer: A,C
Explanation:
The two security policy features that provide the capability to permit access to an application but block its sub-applications are URL filtering and micro application detection. URL filtering allows you to create policies that permit or block access to certain websites or webpages based on URL patterns. Micro application detection is a more sophisticated approach that can identify and block specific applications, even if they are embedded within other applications or websites. According to the Juniper Networks Certified Internet Specialist (JNCIS-SEC) Study Guide [1], "micro application detection is the most accurate way to detect and control applications." Content filtering and APPID are more general approaches and are not as effective in providing the level of granularity needed to block sub-applications.
NEW QUESTION # 32
You want to manually failover the primary Routing Engine in an SRX Series high availability cluster pair.
Which step is necessary to accomplish this task?
- A. Implement the control link recover/ solution before adjusting the priorities.
- B. Issue the set chassis cluster disable reboot command on the primary node.
- C. Adjust the priority in the configuration on the secondary node.
- D. Manually request the failover and identify the secondary node
Answer: B
Explanation:
In order to manually failover the primary Routing Engine in an SRX Series high availability cluster pair, you must issue the command "set chassis cluster disable reboot" on the primary node. This command will disable the cluster and then reboot the primary node, causing the secondary node to take over as the primary node. This is discussed in greater detail in the Juniper Security, Specialist (JNCIS-SEC) Study Guide (page 68).
