Welcome back! It's Wednesday, June 18, and here are the answers to yesterday's Cisco certification exam practice exam questions!



CCENT Certification:

What globally configured command starts a RIP process?



Answer: The router rip command. You don't need to indicate a process number or AS number with RIP.


CCNA Certification:

What are the frame relay LMI types?

Answer: Cisco, ansi, and q933a. Cisco is the default.


CCNP Certification / BSCI Exam:

What port number does BGP use to create neighbor adjacencies?

Answer: That's TCP port 179. Make sure to leave that one unblocked by ACLs!


CCNP Certification / BCMSN Exam:

Classification and marking of data should be done at what layer of the Cisco switching model?

Answer: That should take place as close to the origination point of the data as possible, which means the Access layer.


CCNP Certification / ISCW Exam:

You notice that TCP keepalives are enabled on a router, and you want to disable this feature. What global configuration command will you need to use?

Answer: This is a router service, so we'll use the no service tcp-keepalives command.


CCNP Certification / ONT Exam:

RED has three different modes of packet dropping. Name them.

Answers: "no drop", used when the number of packets in the queue is less than the minimum threshold; "random drop", used when the number of packets in the queue is between the minimum and maximum threshold values; "tail drop", used only when the number of packets exceeds the max threshold. Tail drop can lead to TCP Global Synchronization issues.



New questions later today! Be sure to read yesterday's blog postings for links to three new CCNA and CCENT question sets over on the main site!



To your success,
