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!
