1. An EX Series switch receives a frame with an unknown destination MAC address.
What is the expected behavior?

2. Click the Exhibit button.


You are establishing a BGP session between R1 and R2. R2 shows 172.24.1.1 as its peer address for R1 instead of 192.168.100.1.
Referring to the exhibit, what must be changed in the configuration?

3. What is considered a requirement for passing traffic through GRE tunnels?

4. Which two values are used to generate a bridge ID when using STP? (Choose two.)

5. Click the Exhibit button.


You are troubleshooting an IS-IS adjacency problem as shown in the exhibit.
Which action would solve the problem?

6. You manage a Layer 2 network that spans two buildings. You are asked to ensure that all traffic that traverses this connection between the two buildings is secured.
Which port security feature should be used to secure this Layer 2 traffic?

7. You are troubleshooting your OSPF configuration and notice that you have subnet mismatch errors when running the show ospf statistics command.
Which two actions would further troubleshoot the errors? (Choose two.)

Referring to the exhibit, why is the 0.0.0.0/0 route hidden?

11. What are two OSPF packet types that use multicast for communication on a multicast segment? (Choose two.)

12. Click the Exhibit button.


The configuration shown in the exhibit was committed on an EX Series switch. You are notified that the phone using the voice VLAN does not work. You determine that voice traffic is not passing through the local switch.
What should be done to solve the problem?

13. There is a GRE tunnel configured over the Internet between Router-1 and Router-2. An OSPF adjacency is configured over this GRE tunnel. However, the OSPF adjacency briefly reaches the Full state before it is torn down. This cycle repeats indefinitely.
Which two actions would you perform to solve this problem? (Choose two.)

14. Which two statements are true about link aggregation groups (LAGs)? (Choose two.)

15. Which three mechanisms are associated with the bridging process? (Choose three.)

16. Which two OSPF LSA types will you see in a stub area? (Choose two.)

17. You disconnected a switch from the Virtual Chassis, but the disconnected switch’s member ID is still displayed in the status output.
Which operational command is used to remove the disconnected member?
