Instructions:

Answer 23 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. What is the process for configuring Trunking and VTP. How do we check our work.
On the mapping agent: Create an access list to define the RP's - access-list 25 permit 150.1.3.3 - Create and access list to define the groups - access-list 26 permit 239.0.0.0 0.255.255.255 - Apply the filter - ip pim rp-announce-filter rp-list 25 g
Negotiation conditions - Show interface switchport.
Change interface BW - Change Neighbor Cost - Change Interface ip ospf cost - Change OSPF process reference BW (all routers)
Transport preferred none
