Which adjacency server configuration makes two OTV edge devices located in the same site bring up the dual-site adjacency?
Correct Answer: C
Option C is the correct adjacency server configuration to make two OTV edge devices located in the same site bring up the dual-site adjacency. The adjacency server is a logical entity that maintains the control plane information for the OTV overlay network. The adjacency server can be configured in unicast-only mode, which means that the OTV edge devices use unicast packets to exchange control plane information. To enable dual-site adjacency, which means that the OTV edge devices can form adjacencies with devices in the same site as well as devices in different sites, the adjacency server must be configured with the same IP address on both devices in the same site. The other options have incorrect configurations or IP addresses. For example, option A uses different IP addresses for the adjacency server on the same site, option B uses the same IP address for the adjacency server on different sites, and option D uses an invalid IP address for the adjacency server.

Question 217
Port security is enabled on a Cisco MDS 9000 series Switch. Which statement is true?
Refer to the exhibit. All switches are configured with the default OSPF priority. Which configuration should be applied to ensure that the SW2 Cisco Nexus switch controls the LSA floods and advertises the network to the remaining nodes in the OSPFv2 area?
Correct Answer: A
In OSPF, the router with the highest priority on a network becomes the Designated Router (DR), responsible for generating LSAs for the network. By default, all Cisco routers have an OSPF priority of 1. To ensure that SW2 becomes the DR and controls the LSA floods, its priority needs to be the highest in the OSPFv2 area. The command in option A sets the OSPF priority to the maximum value of 255, which will make SW2 the most likely candidate to be elected as the DR, provided that no other router has a higher priority or a higher router ID if priorities are equal. References := This explanation is based on the OSPF election process as described in Cisco's OSPF design guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials.
