Which statement about aggregate routes is correct?

Show Suggested Answer Hide Answer
Suggested Answer: B, C

Option B is correct.Flooding is a mechanism used in Layer 2 bridging where the switch sends incoming packets to all its ports except for the port where the packet originated1.This is done when the switch doesn't know the destination MAC address or when the packet is a broadcast or multicast1.

Option C is correct.Learning is another mechanism used in Layer 2 bridging where the switch learns the source MAC addresses of incoming packets and associates them with the port on which they were received23.This information is stored in a MAC address table, also known as a bridge table23.

Option A is incorrect.Blocking is a state in Spanning Tree Protocol (STP) used to prevent loops in a network2.It's not a mechanism used in building and maintaining a Layer 2 bridge table2.

Option D is incorrect.Listening is also a state in Spanning Tree Protocol (STP) where the switch listens for BPDUs to make sure no loops occur in the network before transitioning to the learning state2.It's not a mechanism used in building and maintaining a Layer 2 bridge table2.

Haha, I bet someone wrote that B option just to see who would fall for it. Aggregate routes are definitely not auto-generated!

Definitely not option B. Aggregate routes need to be configured manually for summarization.

C sounds like a trap answer. Aggregate routes are not always preferred over more specific routes. The more specific route would be chosen if it has a better path.
