Question #3
Click the Exhibit button. Referring to the exhibit, which statement is correct?
Correct answer: D
Explanation
The Root ID is 8192.50:c5:8d:ae:db:41, so the root bridge priority is 8k. The local Bridge ID is 32768..., so the local priority is 32k and this device is not the root.
Question #6
Click the Exhibit button. Referring to the exhibit, which statement is correct?
Correct answer: B
Explanation
R1 (priority 255) is the DR and R2 (254) is the BDR; R3 and R4 are DROthers and stay in 2Way with each other. Every router in the area, including R3, synchronizes with the DR and holds the complete OSPF database.
Question #10
Referring to the exhibit, which devices will receive the packet sent by User B?
Correct answer: B
Explanation
The hub repeats User B's frame to User C and to the switch. The switch has the destination MAC 00:26:88:02:74:89 in its bridge table on ge-0/0/9, so it forwards only to User D.
