Question27: What are two types of IS-IS PDUs? (Choose two.)

Question28: 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?

Question29: Which statement is true about load balancing of equal cost paths?

Question30: Click the Exhibit button. Given the information shown in the exhibit, what was used to determine mastership?

Question31: Which two statements are true about OSPF not-so-stubby areas? (Choose two.)

Question32: Which two statements describe the BGP Local Preference attribute? (Choose two.)

Question33: Host-1 was recently added in the network and is attached to ge-0/0/10 on Switch-A.
Host-1 is powered on and has its interface configured with default Layer 2 settings and an IP address on the 172.17.12.0/24 IP subnet.
Host-1's MAC address is not shown in Switch-A's bridging table. What are three explanations for this state? (Choose three.)

Question34: You received an alert from your monitoring system that the master Routing Engine (RE) on an EX4300 switch in a virtual chassis has hardware issues and might need to be replaced. Because the switch already had graceful Routing Engine switchover (GRES) enabled and configured, you must perform a manual switchover to the backup RE to avoid disruption.
Which command would be used to perform the manual RE switchover?

Question35: Which statement about IS-IS adjacencies is true?
