Welcome back! Here are the answers to the Cisco certification exam training questions for Saturday, August 11!

CCNA Certification:

What's the broadcast address for a frame?

Answer: The all-Fs MAC address, ff-ff-ff-ff-ff-ff (or FF-FF-FF-FF-FF-FF, as there's no difference between upper and lower case in hexadecimal numbering.)



CCNP Certification / BSCI Exam:

What port number does BGP use to create and maintain adjacencies?

Answer: TCP port 179. Don't block that one with an ACL! :)



CCNP Certification / BCMSN Exam:

What's the maximum number of physical channels that can be placed into an Etherchannel?

Answer: Eight.


CCNP Certification / ONT Exam:

What's the full command for doubling the capacity of the default queue when Priority Queuing is in use?

Answer: Assuming we're using list 1:

priority-list 1 queue-limit 20 40 120 80.

From left to right, we're defining the limit for the high, medium, normal, and low-priority queues. The default queue is the normal-priority queue, and the default capacity for that queue is 60 packets. Even though we're only changing one value, the IOS will make us list a value for all four queues.


Fresh-baked questions posted later today!


To your success,
