Here are the answers to Wednesday evening's Cisco CCNA and CCNP practice questions!
CCNA:
You have just reloaded a router to begin the process of recovering from a lost console password. You have ____________ seconds to send a BREAK to the router.
A. 15
B. 30
C. 45
D. 60
E. 75
F. 90
Answer: D. You've got 60 seconds to send that break sequence, which can be the hardest part of the entire process!
CCNP / BSCI:
In how many EIGRP tables can a successor route be seen?
A. zero
B. one
C. two
D. three
E. four
F. all of them
Answer: C. EIGRP successor routes appear in two tables - the route and topology tables. The successor does not appear in the neighbor table.
CCNP / BCMSN:
Approximately how long does it take a switch running RSTP to detect a down link?
A. The MaxAge value.
B. The Hello Time value.
C. The Forward Delay value.
D. None of these.
Answer: D. A Rapid Spanning Tree (RSTP) port will detect a down link in about 6 seconds. When a RSTP port misses three BPDUs, the link is considered down. The RSTP Hello Time is 2 seconds.
CCNP / BCRAN:
Identify the true statements.
A. DES uses a 56-bit key.
B. DES uses multiple 56-bit keys.
C. 3DES is more easily broken than DES.
D. DES is more easily broken than 3DES.
Answer: A, D. DES uses a 56-bit key, and is much easier to break than Triple DES (3DES).
CCNP / CIT:
Examine the following output and identify the most likely cause.
R1#show interface serial0
Serial0 is down, line protocol is down
A. The cable is loose.
B. The serial interface is shut down.
C. Keepalives are not being received.
D. This interface requires a clockrate and none is being received.
Answer: A. Similar to the other Wednesday set, right? :) But not quite the same. "B" would show the interface as administratively down, and "C" and "D" would result in the physical interface being up while the line protocol would be down.
See you later tonight with more Cisco certification practice questions and answers!
