NEW QUESTION 8
Refer to the exhibits.
Exhibit 1

Exhibit 2

Exhibit 1 shows a portion of the BGP routing table when the BGP solution was first deployed. Exhibit 2 shows the same portion at the current time. What can explain the current state?

Answer: C

NEW QUESTION 9
What is a reason to create a virtual link between two OSPF routers?

• A. to permit OSPF to operate between two routers that also run VRRP
• B. to create a connection between two areas that are not directly connected to Area 0
• C. to permit an OSPF adjacency between two VSF fabrics

Answer: B

NEW QUESTION 10
A network uses MSTP and has AOS-Switches at the access layer. The company wants edge ports on the access layer switches to meet these criteria:
They prevent all rogue switches that run STP, RSTP, or MSTP from connecting to the network.
