It's Wednesday, September 3, and here are the answers to yesterday's Cisco practice exam questions!

CCNA Security tutorials and practice exams will be posted 5 - 7 times per week beginning today!

Let's take a look at yesterday's questions....

CCNA Certification And CCENT Certification:

Identify the true statements regarding Telnet.

A. Telnet operates at L3 of the OSI model.

B. Telnet operates at L4 of the OSI model.

C. A telnet password is not set by default on a Cisco router, but is required.

D. A telnet password is not set by default on a Cisco router, and none is required.

E. Incoming users are placed into the highest privilege level possible by default.

F. Incoming users can do relatively little by default.

Answers: C, F. Telnet runs at Layer 7 of the OSI model. No VTY line password is set by default, but you'll have to set one to allow Telnet connections to your router. By default, remote users can do very little. You can assign a higher privilege level on either a per-user basis or for all incoming users by configuring the privilege level command on the VTY lines.

CCNA Security Certification / CCNP ISCW Exam:

If you select multiple SDM files in the following window, how will the router decide which one to attempt to load first?

A. In order of size, the largest file first.

B. In order of size, the smallest file first.

C. In the order you list them here.

D. You can't select more than one SDM file.

Answer: C. The screen hints at it a bit - note that you can move the file names up and down.

CCNA Wireless:

Short answer: What's the main difference between an autonomous access point and a lightweight access point?

Answer: Autonomous APs are configured individually, where lightweight APs can be configured via LWAPP. Autonomous APs do not understand LWAPP.

CCNA Voice:

Short answer: To enable cRTP on this interface, what's the next command you should enter?

R1(config)#int serial0

R1(config-if)#encap frame


Answer: You'll need the ip rtp header-compression command. The frame mappings on that interface will inherit that setting, as shown below.

R3(config)#int s0/0/0
R3(config-if)#encap frame
R3(config-if)#ip rtp header-compression
R3(config-if)#frame map ip 221 broadcast
R3(config-if)#frame map ip 221 broadcast

R3#show frame map
Serial0/0/0 (up): ip dlci 221(0xDD,0x34D0), static,
broadcast, CISCO, status active
RTP Header Compression (inherited), connections: 256

Serial0/0/0 (up): ip dlci 221(0xDD,0x34D0), static,
broadcast, CISCO, status active RTP Header Compression (inherited), connections: 256

CCNP Certification / BSCI Exam:

Short answer: What is the difference between an OSPF E2 route's metric and an E1 route metric?

Answer: An E2 metric reflects only the cost from the ASBR to the external destination . It does not reflect the cost from the local router to the ASBR itself. An E1 metric does include the cost from the local router to the ASBR.

CCNP Certification / BCMSN Exam:

Identify the statements that accurately describe a SPAN destination port.

A. Can participate in multiple SPAN sessions

B. Can also be a source port

C. Can be part of an Etherchannel

D. Can be either a Fast Ethernet or Ethernet port

Answers: D. Destination SPAN ports can't take part in multiple SPAN sessions, they can't also be source ports, and they can't be part of an Etherchannel.

CCNP / ONT Exam:

Short answer: What application is in use in the following illustration?
Answer: That's just a very small part of the information you can access in Cisco's Wireless LAN Controller (WLC).

I've got a new CCNA Security tutorial for you today, at least one new practice exam, and some other great surprises on the way!

While you're waiting, spend some time on my free CCNA, CCNP, and CCENT tutorials page!

To your success,
