Welcome back! Here are the answers to Monday's Cisco CCNA and CCNP certification questions!
CCNA:
Which of the following helps to limit the number of broadcasts handled by a switch?
A. STP
B. Root Bridges
C. VLANs
D. BPDUs
Answer: C. VLANs help to reduce the number of broadcasts on a switch, since a broadcast sent by a member of any VLAN will only be received by the other members of that VLAN. By default, a Cisco switch will forward a broadcast out every port except the port that originally received the broadcast.
CCNP / BSCI:
The command summary-address is designed for use on what OSPF router type(s)?
A. ABRs only
B. ASBRs only
C. ASBRs and ABRs
D. ABRs and all routers in a stub area
E. ABRs and all routers in a total stub area.
F. Any router that is not in any kind of stub area.
Answer: B. The command summary-address is designed for use only on an ASBR. This command is used to summarize routes that are being redistributed into OSPF. Here's how the command is used on a Cisco router:
R1(config)#router ospf 1
R1(config-router)#summary-address 4.0.0.0 252.0.0.0
CCNP / BCMSN:
Which of the following is true of the "collapsed core" design?
A. There is no dedicated access-layer switch.
B. There is no dedicated distribution-layer switch.
C. There is no dedicated core-layer switch.
D. All three layers are found on one switch.
Answer: B, C. A "collapsed core" design has switches share the role of distribution- and core-layer switches. There are still dedicated access-layer switches.
CCNP / BCRAN:
What is the net effect of the command isdn caller 555xxxx ?
A. The router will accept calls only if the called number begins with 555.
B. The router will accept calls only if the calling number begins with 555.
C. This is an illegal command and will not be allowed by the IOS.
D. The command is legal, but does not allow the use of the letter x for a wildcard.
Answer: B. The router will accept calls only if the calling number begins with 555. The "x" characters are wildcards.
CCNP / CIT:
Identify the true statements regarding OSPF.
A. Area 0 can use link authentication.
B. Area 0 cannot use link authentication.
C. If Area 0 is authenticated, virtual links must be as well.
D. Virtual links cannot be authenticated, but Area 0 can be.
Answer: A, C. Area 0 can indeed use link authentication, and if you do so, any virtual links will need to use link authentication as well.
