Thursday's CCNA / CCNP Practice Questions And Answers
Friday's questions will be posted later this afternoon.
CCNA:
Which of the following statements will create a static route that will send packets to the destination IP address 2.2.2.2, but cannot be used to send packets to any other destination?
A. ip route 2.2.2.2 0.0.0.0 172.12.123.1
B. ip route 2.2.2.2 255.255.255.255 172.12.123.1
C. ip route 2.2.2.2 172.12.123.1 0.0.0.0
D. ip route 2.2.2.2 172.12.123.1 255.255.255.255
E. ip route 0.0.0.0 0.0.0.0 172.12.123.1
F. ip route 0.0.0.0 172.12.123.1 0.0.0.0
ANSWER: B. A route that matches a single host is a host route, and a static host route has 255.255.255.255 for a mask. The end IP address is the next-hop IP address. "E" is a default static route, which could be used to route packets to 2.2.2.2, but the question stated that a route should be selected that would match no other routes.
CCNP / BSCI:
What is the ISIS equivalent of OSPF's Area 0?
A. The L2 backbone.
B. The L1 backbone.
C. There is no backbone area in ISIS.
D. Area 0
E. Area 0000.0000.0000
ANSWER: A. The L2 backbone is the equivalent of OSPF's Area 0.
CCNP / BCMSN
A switch port is enabled with PortFast. You are concerned that another switch may one day be connected to that switch port and become the root bridge of your network. What STP feature is designed to prevent this from happening?
A. Switch Guard
B. Loop Guard
C. BPDU Guard
D. UplinkFast
E. BackboneFast
ANSWER: C. When PortFast is configured on a port, it may be advisable to configure BPDU Guard on that port as well. No device connected to a PortFast port should be sending BPDUs. When BPDU Guard sees a BPDU come in on such a port, the port will be placed into err-disabled state.
