Which feature should you use to address this concern?

persistent MAC learning

802.1X

DHCP snooping

MAC limiting

12. You are running a Virtual Chassis with nonstop routing enabled. You want to confirm that the BGP routing table synchronization has completed on the backup Routing Engine.

Which command will show you this information?

show task replication

show bgp summary

show bgp neighbor

show bgp replication

13. Click the Exhibit button.

Referring to the exhibit, the IRB interfaces are configured with which family?

irb

ethernet-switching

14. Click the Exhibit button.

Referring to the exhibit, Router 1 learns about Route X.

Which statement is correct about Route X when using the default BGP advertisement rules?

R1 will not advertise this route to any peers.

R3 will not advertise this route to R4 or R5 without an explicit policy.

R4 and R5 will not advertise this route to each other.

R2 will not advertise this route to R3 without an explicit policy.

15. What types of authentication are supported in Junos for OSPF?

Simple password

MD5 checksum

Hitless key chain of MD5 keys/checksums

All of the above

16. Which statement about persistent MAC learning is correct?

Trunk ports require MAC addresses to be configured on each VLA

Port moves require manual operator intervention.

Access ports must be configured with the no-mac-learning command.

802.1X must be configured on the port for persistent MAC learning to work.

17. Exhibit.

You are attempting to set up VRRP with R1 and R2 being participating members. You want R1 to be the master router and R2 to be the backup router with the virtual router they create being at address 172.25.100. 1. The virtual router is not pinging from either User A or User B.

Referring to the exhibit, what must be done to correct the problem?

The VRRP group value on R1 and R2 must match.

A VRRP policy is needed on R1 and R2.

The VRRP priority value on R1 and R2 must match

18. You are a service provider and have multiple customers in a building.

You are installing a new switch that can host all of your customers. However, you would like to ensure that one customer cannot see or broadcast to another customer.

What should be used to provide this access?

VLAN

private VLAN

filter-based VLAN

Layer 2 tunneling

19. 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.
