Here are the answers to Wednesday's Cisco certification exam practice questions!
CCNA:
A device boots up, and does not have an IP address assigned to it. Which of the following two protocols will assign an IP address to such a device?
A. ARP
B. IARP
C. RARP
D. DHCP
E. DNS
F. WINS
Answers: C, D. Dynamic Host Configuration Protocol (DHCP) is the most common method, but don't forget about Reverse Address Resolution Protocol (RARP).
CCNP / BSCI:
An ISIS L1 router needs to send packets to another area. How will it do so?
A. By using the default route advertised by the area's L2 router.
B. By sending the packets to an L1/L2 router.
C. By sending the packets to the L1 Designated Router.
D. By sending the packets to the ASBR.
Answer: B. For an L1 router to send data to another area, the data will have to be transmitted to an L1/L2 router. L1 routers cannot send data directly to an L2, since they cannot form an adjacency.
CCNP / BCMSN:
R3's port fast 0/10 is configured with Root Guard. An inferior BPDU is received on that port. What will happen?
A. Nothing.
B. The port will go into err-disabled state.
C. The port will go into port-inconsistent mode.
D. The port will go into blocking mode.
Answer: A. Root Guard takes no action when an inferior BPDU is received. When a superior BPDU is received, though, the port will go into root-inconsistent state.
