Question

You have three Hyper-V hosts named Server1, Server2, and Server3 that run Windows Server. Server1 hosts a virtual machine named VM1. You enable Hyper-V Replica to replicate VM1 to Server2 and set the replication frequency to 30 seconds. You need to extend the replication and create a second replica of VM1. On which Hyper-V hosts should you configure the replication, and what is the minimum replication frequency you can use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Answer Area Hyper-V hosts: [Dropdown] Replication frequency: [Dropdown]

Explanation

This question tests knowledge of Hyper-V Extended Replication, where a secondary replica (replica of a replica) is created on a third host, and the minimum replication frequency constraints that apply in that scenario.

Approach. To configure extended replication (a second replica of VM1), you must configure replication FROM Server2 (the existing replica server) TO Server3 - not from Server1. Server1 is the primary host and Server2 is the first replica; Server2 becomes the new 'source' for the extended replica on Server3. The minimum replication frequency for extended replication is 5 minutes (300 seconds). Even though the primary-to-replica replication is set to 30 seconds, Hyper-V Extended Replication does not support frequencies of 30 seconds or less - the minimum allowed frequency for a secondary (extended) replica is 5 minutes.

Concept tested. Hyper-V Extended Replication: configuring a replica-of-a-replica requires replication to be set up on the replica server (Server2 → Server3), and the minimum replication frequency for extended replication is 5 minutes, regardless of the primary replication frequency.
