It's Monday, October 13, and here are the answers to Saturday's questions!
A. If both the enable secret and enable password are configured, the enable secret takes precedence.
B. The options for the end of the ip route command are local IP address of exit interface and name of exit interface.
C. To clear a route table of its RIP routes, run clear ip route rip.
D. Debugs must be turned off individually; there is no single command to stop all debugs currently running on a Cisco router.
Answers: A. The enable secret password does take precedence over the enable password. Reasons the other statements are false:
If you specify the IP address at the end of the ip route command, that's the IP address of the next-hop router, not an address on the local router.
You can run clear ip route * to clear all dynamically learned routes, but there is no clear ip route rip command.
You can use undebug all to stop all currently running debugs ("u all").
You see a green box next to a signature in SDM. What does that green box indicate?
Answer: The parameter is set to the default. A red diamond indicates the parameter has been edited.
Identify the true statements regarding OSPF and Cisco-recommended best practices.
A. No router should be in more than two areas.
B. No area should contain more than 50 routers.
C. There's no problem with a Cisco router acting as a DR or BDR for more than one network segment.
D. The ABR should run no more than one OSPF process.
Answer: B, D. Other recommendations are that no router should be in more than three areas (not two), and that a router generally should not act as the DR or BDR for more than one segment. (In real-world networks, powerful routers can and do serve in that multi-DR role.)
CCNP Certification / BCMSN Exam:
Which of the following statements are true?
A. ISL encapsulation adds 30 bytes overall to the frame size.
B. Dot1q adds to the overall frame size, but the frame is not encapsulated.
C. Frames destined for the native VLAN are not appended by either ISL or dot1q.
D. IEEE 802.3ac allows a maximum frame length of 1522 bytes.
Answer: A, B, D. C is false because ISL encapsulates all frame with no regard for the native VLAN.
At what layer of the OSI model does LFI take place? Is LFI a default behavior?
Answer: Link Fragmentation and Interleaving takes place at the Data Link layer, and it is not a default behavior.
