CCNA: Cisco Certified Network Associate — Question 769

A Cisco engineer notices that two OSPF neighbors are connected using a crossover Ethernet cable. The neighbors are taking too long to become fully adjacent. Which command must be issued under the interface configuration on each router to reduce the time required for the adjacency to reach the FULL state?

Answer options

• A. ip ospf dead-interval 40
• B. ip ospf network broadcast
• C. ip ospf priority 0
• D. ip ospf network point-to-point

Correct answer: D

Explanation

The correct command is 'ip ospf network point-to-point', as it configures OSPF to treat the link as a point-to-point connection, which reduces the amount of OSPF overhead and allows for faster convergence. The other options either change different parameters that do not directly impact the adjacency speed, such as dead intervals, broadcast settings, or priorities, which are not effective in this scenario.
