Question

You have two servers that run Windows Servers,  have the DHCP Server role installed and are in DHCP failover relationship.

The DHCP failover relationship state is listed as communication interrupted.

You need to restore the DHCP functionality. The solution must minimize downtime.

What should you investigate first?

Select only one answer.

Proposed answer
  • DNS server failure
  • incompatible DHCP server configurations  
  • interruption to the network link between DHCP failover partners
  • lack of DHCP scope exclusions 
Correct answer

interruption to the network link between DHCP failover partners 

  • Incorrect - DNS server failure is not a direct cause of the communication interrupted state in a DHCP failover relationship.
  • Incorrect - Incompatible DHCP server configurations can cause a failover relationship to be in the partner down state, but it is not a direct cause of the communication interrupted state.
  • Correct - In a Windows Server DHCP failover relationship, the interrupted communication state can occur due to an interruption on the network link between the DHCP failover partners or because the DHCP Server service on a failover partner is unresponsive. This can cause a DHCP client to lose communication with one or both DHCP servers, interrupting the DHCP Server service for clients on the affected network segment.
  • Incorrect - While a lack of DHCP scope exclusions can cause a DHCP Server service interruption, it is not a direct cause of the communication interrupted state in a DHCP failover relationship.
