Here are the answers to the free Cisco certification exam training questions for Wednesday, October 3!
CCENT Certification:
Which of the following is *not* associated with UDP?
A. guaranteed delivery
B. sliding window
C. sequence numbering
D. acknowledgement numbers
Answer: A, B, C, D. None of those is associated with UDP - they're all terms that describe TCP or a TCP header field.
CCNA Certification:
Briefly describe the channels that make up an ISDN BRI.
Answer: In an ISDN BRI, we've got two B-channels and one D-channel. The D-channel is responsible for call maintenance and teardown, while the B-channels carry the actual data. Each B-channel has a capacity of 64 kbps, while the D-channel is a 16 kbps channel.
CCNP Certification / BSCI Exam:
If a router receives a BGP update and sees its own AS in the update, what action is taken?
Answer: That particular route update is ignored. This is a loop prevention feature.
CCNP Certification / BCMSN Exam:
What is the default root path cost of a Fast Ethernet port?
Answer: 19. The cost is dependent on the speed of the port.
CCNP Certification / ISCW Exam:
What protocol number does the Authentication Header use?
Answer: The AH header uses protocol number 51.
CCNP Certification / ONT Exam:
Name three Frame Relay marking values and briefly describe them.
Answer: Actually, these go back to your CCNA studies!
BECN - Backward Explicit Congestion Notification - indicates congestion was encountered in the opposite direction in which the frame was traveling when received.
FECN - Forward Explicit Congestion Notification - indicates congestion was encountered in the direction in which the frame was traveling when received.
DE - Discard Eligible - indicates that a particular frame is considered less important than others, and therefore should be dropped first if frames need to be dropped due to network congestion.
New questions posted later today, and look further down the blog for links to several new CCENT and CCNA exam tutorials!
