Here are the answers to yesterday's practice questions.
CCNA:
What problem does the Cisco feature router on a stick resolve?
A. Multiple devices having the same private IP address.
B. Hosts in one VLAN cannot communicate with hosts in other VLANs.
C. Routers do not forward broadcasts.
D. Switches do not forward broadcasts.
Answer: B. Router on a stick is a solution to the inability of VLANs to send traffic to each other.
CCNP / BSCI:
What combination of hex characters at the beginning of an IPv6 address indicates a broadcast?
A. AA
B. FF
C. 00 (two zeroes)
D. None
Answer: D. IPv6 doesn't use broadcasts. IPv6 traffic is either an anycast, a unicast, or a multicast.
CCNP / BCMSN:
Under what circumstances would you configure Uplinkfast on a root switch?
A. None. Actually, you can't.
B. You want the remote port to open a new connection to the root quickly.
C. You want the root switch's ports to skip the listening and learning states.
D. You want to eliminate all delays on all the root's switch ports regarding STP.
Answer: A. You can't configure Uplinkfast on a root switch. Actually, when you configure Uplinkfast on a nonroot switch, that switch's priority is hiked and port costs raised to prevent that switch from ever becoming the root.
