az-801 Practice Question 1916
Exam: az-801
Domain: Implement disaster recovery
Topic: Implement disaster recovery by using Azure Site Recovery
Difficulty: medium
During a disaster recovery test using Azure Site Recovery (ASR), a Mobility Service agent on an on-premises Hyper-V host fails to replicate data to Azure. What is the most likely cause of this issue, and how should it be resolved?
Answer Options
A
Incorrect protection settings were configured for the virtual machine.
B
Network connectivity issues between the on-premises environment and Azure.
C
The virtual machine is not powered on in the on-premises environment.
D
The Azure subscription does not have sufficient storage capacity.
Correct Answer
B: Network connectivity issues between the on-premises environment and Azure.
Explanation
The correct answer is B because the Mobility Service agent is responsible for replicating data between the on-premises environment and Azure. If the agent fails to replicate data, it could be due to a network connectivity issue between the on-premises environment and Azure. The recommended action is to check the network connectivity and ensure that the necessary ports are open. Options A, C, and D are incorrect as they do not address the root cause of the replication failure.
