Question No.37

Which three LSA types are valid for OSPFv2? (Choose three)

1. Router LSA: an LSA sent by every router. This LSA includes the state and the cost of all links and a list of all OSPFv2 neighbors on the link

2. AS Internal LSA: an LSA generated by the ASBR. AS Internal LSAs are flooded only within the autonomous system

3. Backbone Summary: an LSA sent by the backbone router to all the OSPF areas

4. DR Summary LSA: an LSA sent by the DR router to all the others on network

5. Default LSA: an LSA generated by the ASBR. These LSAs are used to propagate default route into OSPF

6. Network LSA: an LSA sent by the DR. This LSA lists all routers in the multi-access network

7. Opaque LSA: an LSA used to extend OSPF

Correct Answer: AFG

2. If MSTP is enabled, a separate MST instance must be used for FCoE VLANs

3. Cisco UF links must be configured as spanning-tree edge ports

4. A shared VLAN can be used to carry traffic for each virtual fabric in the SAN (for example, VLAN 1002 for VSAN 1, VSAN 2, and so on)

5. Separate FCoE VLANs must be used for FCoE in SAN-A and SAN-B

6. A blade switch must connect to multiple converged access switched in a topology.
