Here are the answers to Saturday's first set of CCNA, CCNP, and Network+ practice questions!

CCNA:

The LMI serves as a keepalive for which of the following?

A. ISDN

B. OSPF

C. RIPv2

D. Frame Relay

E. Switched trunks

Answer: D. The Local Management Interface (LMI) serves as a keepalive for Frame Relay.



Network+:

Which of the following can be used to allow hosts on different subnets to communicate?

A. Hub

B. Repeater

C. L2 switch

D. L3 switch

E. Router

F. Bridge

Answers: D, E. To allow hosts on different subnets to communicate, routing has to take place. That means that we have to have a router or Layer 3 switch (a switch that can perform routing) involved.


CCNP / BSCI:

Identify the true statements.

A. RIPv1 is classful, RIPv2 is not.

B. RIPv1 is classless, RIPv2 is not.

C. RIPv1 allows clear-text update authentication, RIPv2 does not.

D. RIPv2 allows clear-text update authentication, RIPv1 does not.

E. Both RIPv1 and V2 allow clear-text update authentication.

F. Both RIPv1 and V2 allow MD5 update authentication.

G. Both RIPv1 and V2 allow SHA update authentication.

Answers: A, D. RIP version 1 is classful, and version 2 is classless. RIPv2 allows both MD5 and clear-text authentication of routing update packets, but RIPv1 offers neither.



CCNP / BCMSN:

Can a switch be configured to open an err-disabled port on its own, rather than require manual intervention?

A. No.

B. Yes, with the errdisable recovery command.

C. Yes, by configuring the switch to reboot during off-hours.

D. Yes, with the port autoopen command.

Answer: B. The errdisable recovery command allows this to happen. You can also define how long the port should remain disabled before bringing the port out of err-disabled state.




CCNP / BCRAN:

IKE Phase I can run in which of the following two modes?

A. Tunnel

B. Transport

C. Quick

D. Main

E. Aggressive

F. Passive

Answers: D, E.



CCNP / CIT:

Short answers: What interface type(s) must use the frame interface-dlci command when configured for Frame Relay?

Answer: Point-to-point subinterfaces must use the frame-relay interface-dlci command. Cisco routers will not allow you to configure this command on physical interfaces or point-to-multipoint subinterfaces.

See you in a few minutes with the answers to Saturday's bonus set of CCNA, CCNP, and Network+ exam questions!
