Question: 316

Why do Cisco MPLS TE tunnels require a link-state routing protocol?

A . The link-state database provides segmentation by area, which improves the path-selection process.

B . The link-state database provides a data repository from which the tunnel endpoints can dynamically select a source I

D . Link-state routing protocols use SPF calculations that the tunnel endpoints leverage to implement the tunnel. E . The tunnel endpoints use the link-state database to evaluate the entire topology and determine the best path.

Answer: D

Question: 323

Refer to the exhibit.

A network engineer is implementing an OSPF configuration. Based on the output, which statement is true?

A . OSPFv3 does not run for IPv4 on FastEthernet0/0 until IPv6 routing is enabled on the router and IPv6 is enabled on interface FastEthernet0/0.
