AZ-802 Practice Question: Implement and Manage On-Prem and Hybrid Networking
Exhibit
PS C:\> Get-DhcpServerv4Failover Name : Corp-Failover PartnerServer : 192.168.1.10 Mode : LoadBalance State : CommunicationInterrupted MaxClientLeadTime : 01:00:00
Refer to the exhibit displaying the status of a DHCP failover relationship. A network administrator notices the 'CommunicationInterrupted' state. What is the immediate impact on DHCP clients that attempt to renew their leases while the server is in this state?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The server continues to renew leases for the duration of the MCLT.
In a DHCP failover configuration, the 'CommunicationInterrupted' state indicates that the two servers can no longer talk to each other. This state is designed to ensure continuity of service. Understanding how the Max Client Lead Time (MCLT) and server roles function during this interruption is critical for maintaining network availability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Clients cannot renew leases and will lose connectivity immediately.
Why it's wrong here
DHCP failover is specifically designed to prevent immediate connectivity loss. In the event of a communication failure, the remaining server continues to service the clients it is aware of, ensuring that existing devices can maintain their network presence while the administrator works to resolve the underlying connection issue.
- ✗
The server will grant new leases for the full scope duration.
Why it's wrong here
During a communication interruption, the server is restricted in how long it can extend or grant leases because it cannot synchronize with its partner. Granting full-duration leases without synchronization could lead to IP address conflicts once the partnership is restored and the two databases are reconciled.
- ✓
The server continues to renew leases for the duration of the MCLT.
Why this is correct
When communication is interrupted, the server will continue to renew leases for its clients but only for the duration specified by the Max Client Lead Time (MCLT). This safety mechanism ensures clients stay connected while preventing the server from permanently exhausting the IP pool without partner confirmation.
- ✗
The partner server automatically takes over all active leases.
Why it's wrong here
A takeover does not happen automatically in the 'CommunicationInterrupted' state. The servers must wait for the 'Partner Down' state to be manually or automatically triggered (if the transition delay is configured) before one server assumes full responsibility for the entire IP address range and all active client leases.
