Hello again! I hope you're enjoying your weekend. Here are the answers to Friday's Cisco and CompTIA certification exam practice questions!
CCNA:
A frame enters a switchport. The destination MAC address is known. Which of the following terms best describes how the frame will be transmitted?
A. unicast
B. multicast
C. broadcast
D. filtered
E. forwarded
F. framed
Answers: A, E. A frame with a known MAC address will be unicast - that is, sent out the port leading to the destination. This is also called forwarding the frame.
Network+ :
Short answer: What are the three RFC 1918 private address ranges?
Answer: The Class A range is 10.0.0.0 255.0.0.0 (/8); the Class B range is 172.16.0.0 255.240.0.0 (/12); the Class C range is 192.168.0.0 255.255.0.0 (/16).
CCNP / BSCI:
Identify the true statements regarding route maps.
A. The sequence number increments 10 by default.
B. The sequence number increments 20 by default.
C. If no permit or deny is specifed in the route map, it's treated as a permit.
D. If no permit or deny is specified in the route map, it's treated as a deny.
Answers: A, C. Remembering that the sequence number increments by 10 is easy; it's the other part that's a little tough. You must keep in mind that if you do not specify "permit" or "deny" in a route-map statement, it is considered a permit statement.
R1(config)#route-map BSCIPASS (no permit or deny specified)
R1(config-route-map)#match ip address 17
R1(config-route-map)#set ip next-hop 100.1.1.3
R1#show route-map
route-map BSCIPASS, permit, sequence 10 (default: permit, sequence number 10)
Match clauses: ip address (access-lists): 17 Set clauses: ip next-hop 100.1.1.3
CCNP / BCMSN:
What Cisco switching feature reduces the number of broadcasts crossing a trunk?
A. VTP pruning
B. VTP PortFast
C. VTP Etherchannels
D. VTP Revision Number Acceleration
Answer: A. That's what VTP pruning is all about! When VTP Pruning is enabled, the only broadcasts that will be permitted to cross the link are those broadcasts destined for VLANs that actually do have member ports on the remote switch - and that's a good thing!
CCNP / BCRAN:
Which of the following is the amount of bandwidth guaranteed by the frame relay provider?
A. CRMI
B. CIR
C. DE
D. EIR
E. BECN
F. BE
Answer: B. That's the Committed Information Rate - CIR.
CCNP / CIT:
Short answer: You've just described a problem to Cisco TAC. The network is down, business processes are critical, and there's no workaround. What priority level will TAC most likely assign to this case?
Answer: This case would most likely be assigned the highest priority level possible with TAC, Priority 1.
That about does it for today! I'll see you tomorrow with the answers to today's questions, more free Cisco and CompTIA certification exam questions, and who knows what else!
