VMware NSX 4.x Professional (2024) — Question 59

When configuring OSPF on Tier-0 Gateway, which three of the following must match in order to establish a neighbor relationship with an upstream router? (Choose three.)

Answer options

• A. Area ID
• B. MTU of the Uplink
• C. Naming convention
• D. Address of the neighbor
• E. Subnet mask
• F. Protocol and Port

Correct answer: A, B, E

Explanation

The correct parameters that must match for OSPF neighbor relationships are Area ID, MTU of the Uplink, and Subnet mask. The Area ID ensures routers are in the same OSPF area, the MTU must be the same for packets to be transmitted correctly, and the Subnet mask must match for accurate routing. The other options, such as Naming convention and Address of the neighbor, are not critical for establishing OSPF neighbors.
