NEW QUESTION 50
Click the Exhibit button. Based on the output shown in the exhibit, which statement is correct?

NEW QUESTION 52
Click the Exhibit button. In the exhibit, each IP subnet in the campus environment is associated with a unique VLAN ID.
Which action will ensure that Host C will communicate with Host A and Host B?
- A. Configure all switch ports connecting to the host devices as trunk ports associated with all VLANs.
- B. Configure a port-based ACL that permits inter-VLAN routing for all configured VLANs.
- C. Configure all switch ports connecting to the host devices as access ports associated with a common VLAN.
- D. Configure an IRB interface for each VLAN and associate it with its corresponding VLAN.
Answer: D
Explanation:
Configuring Routing Between VLANs on One Switch To segment traffic on a LAN into separate broadcast domains, you create separate virtual LANs (VLANs). Of course, you als o want to allow these employees to communicate with people and resources in other VLANs. To forward packets between VLANs you normally you need a router that connects the VLANs. However, you can accomplish this on a Juniper Networks switch without using a router by configuring an integrated routing and bridging (IRB) interface (also known as a routed VLAN interface-- or RVI-- in versions of Junos OS that do not support Enhanced Layer 2 Software).

Answer: B
NEW QUESTION 57
Exhibit.
You have configured OSPF routing as shown in the exhibit. You notice that all interfaces have formed full adjacencies, with the exception of the interfaces connecting R3 and R4 with a status of 2Way.
What is the reason for this status?
- A. The two routers must be configured in different areas.
- B. The interface-type is not configured as p2p.
- C. The two routers must both be configured as DR routers.
