It's Monday, September 22, and here are the answers to Saturday's Cisco certification practice exam questions!

CCNA Certification And CCENT Certification:

Take a look at the following configuration and answer these questions:

1. What's the escape sequence mentioned in the first line?

2. What two commands combined to create this output?

3. What is a more common name for "ICMP Echos"?

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 136/139/152 ms
IP: s= (local), d= (Serial0), len 100, sending
IP: s= (Serial0), d= (Serial0), len 56, rcvd 3
IP: s= (Serial0), d= (Serial0), len 100, rcvd 3
IP: s= (local), d= (Serial0), len 100, sending

Answers: The escape sequence is crtl-c. The two commands running are debug ip packet and ping (the destination of the pings is indicated by "d="), and naturally the ICMP Echos are commonly called pings.

CCNA Security Certification / CCNP ISCW Exam:

Which of the following does IKE *not* negotiate?

A. IKE keys

B. IPSec Security Agreements

C. QM_IDLE mode (Tunnel or Transport)

D. authentication of IPSec peers

Answer: C. There's no such thing as QM_Idle mode, but IKE does negotiate the other three values.

CCNA Wireless:

Define the term modulation, and discuss briefly what the term means in today's wireless networks.

Answer: Modulation refers to the addition of information to a signal; the "mo" in modem refers to this process. In wireless networking, information is added to a radio signal in order to transmit the data in that fashion.

CCNA Voice:

Which of the following is *not* a VoIP signaling protocol?






Answer: C, E. Yagi and uni(directional) are antenna types. The others are VoIP signaling protocols.

CCNP Certification / BSCI Exam:

What message should you expect the router to display immediately after entering the following configuration?

R1(config)#router ospf 1
