It's Friday, May 16, and we're just 6 days away from the release of The Ultimate ISCW Study Package!

Also, The Ultimate CCNP All-In-One Video Boot Camp will be released early next week!

You'll receive over 50 hours of video instruction from yours truly, online support for your studies, and a download that will have you studying for the BSCI exam immediately after your purchase.

All four CCNP exams are covered in this Video Boot Camp!

Hang in there - I've gotten hundreds of emails regarding both items, and no, I can't sneak you one early. :) I guarantee you'll be very happy with both items!

While we're waiting not-so-patiently, let's check out the answers to Thursday's free Cisco certification exam practice questions!

CCENT Certification:

Which of the following is *not* associated with UDP?

A. guaranteed delivery

B. windowing

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:

When you run the ip ospf hello 30 command, you've actually set two values. The first one's pretty obvious, but what's the second one?

Answer: When you change the OSPF hello time, the OSPF dead timer is also dynamically changed. By default, the OSPF dead timer is 4 times the hello time, so that command would set the hello-time to 30 seconds and the dead-time to 120 seconds.

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!

To your success,
