CCNP Certification / ISCW Exam:
What protocol numbers do AH and ESP use?
Answers: Authentication Header (AH) uses IP protocol number 51, while Encapsulating Security Payload (ESP) uses IP protocol number 50.
CCNP Certification / ONT Exam:
Examine the following configuration. Assuming all packets being transmitted are 1400 bytes in size, how many packets will Queue 1 transmit before it's Queue 2's turn to send?
R1(config)#queue-list 1 queue 1 byte-count 3000
R1(config)#queue-list 1 queue 2 byte-count 2000
R1(config)#queue-list 1 queue 3 byte-count 1000
R1(config)#queue-list 1 queue 4 byte-count 1000
Answer: Three. After Q1 sends one 1400-byte packet, there are 1600 bytes left in its turn. After sending a second packet, there are 200 bytes left. In that circumstance, PQ will send another packet, since the queue is still under its limit. PQ will *not* fragment the packet, but will send it in its entirety.
