13. You have an IBGP neighbor sending you routes. You need to apply a policy so it only evaluates routes being learned from this specific neighbor.

In this scenario, which statement is correct about applying the policy?

The policy should be applied as an export policy to the BGP group level.

The policy should be applied as an import policy to the BGP group level.

The policy should be applied as an export policy to the BGP neighbor level.

The policy should be applied as an import policy to the BGP neighbor level.

14. Click the Exhibit button.

Referring to the exhibit, what does the asterisk (*) following the ge-0/0/5.0 interface indicate?

It indicates the interface is not active.

It indicates the interface is a trunk port.

It indicates the interface is an access port.

It indicates the interface is active.

15. Click the Exhibit button.

You are implementing the network shown in the exhibit. You must ensure that all users can communicate with each other.

What are three steps that should be taken in this scenario? (Choose three.)

You must define all ports as trunk ports and include all VLANs as members.

You must define all ports as access ports and include the appropriate VLAN as a member.

You must configure a single logical IRB interface with an IP address for each of the three networks.

You must create a unique logical IRB interface for each network and assign an IP address within the appropriate network.

16. Which two statements about Martian addresses are correct? (Choose two.)

Martian addresses are not installed in the routing table by default.

Martian addresses can only be applied to the inet.0 routing table.

Martian addresses are installed in the routing table by default.

17. You are asked to configure filter-based forwarding (FBF) to forward traffic sourced from a specific subnet to a webserver.

RIB groups

routing instances

forwarding instances

filter-based forwarding
