Welcome back! Here are the answers to the Cisco certification exam training questions for Thursday, May 29!

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.

CCNP Certification / ISCW Exam:

Which of the following IOS Firewall Set configurations would require the use of Security Device Manager's Advanced Firewall Wizard?

A. one trusted interface, two untrusted interfaces, no DMZ

B. two trusted interfaces, two untrusted interfaces, no DMZ

C. one trusted interface, one untrusted interface, one DMZ

D. two trusted interfaces, one untrusted interface, one DMZ

Answers: A, B, C, D. All of these scenarios would require the use of the Advanced Firewall Wizard. The Basic Firewall Wizard has the ability to configure multiple inside interfaces, but only one outside ("untrusted") interface. Additionally, the Basic Firewall Wizard has no DMZ configuration capabilities.

New questions later today!

To your success,
