Here are the answers!
CCNA and CCENT Answers: B, D, F. To use the password encryption service, you'll need to use the service password-encryption command, since that service is disabled by default.
The particular encryption used by that command is relatively weak; it'll stop people from casually peeking at the password, but several programs exist that can crack this particular encryption in a matter of seconds.
There is no default VTY line password.
CCNA Security / ISCW Exam Answer: A. You will be prompted to allow the routing updates.
CCNA Wireless Answers: B, C, D. WEP uses static keys, one-way authentication, and a weak encryption scheme. ("Other than that, Mrs. Lincoln, how did you enjoy the play?")
CCNA Voice Answer: A, B. POTS dial peers do not use the session-target command, and neither POTS not VOIP peers use the dial map command.
CCNP BSCI Answer: B. The default OSPF route code is E2.
CCNP BCMSN Answers: A, B, C. D. All four statements are accurate.
CCNP ONT Answer: A, B, C. That's RTP Header Compression, which compresses the IP, RTP, and UDP headers.
