NEW QUESTION 26
A storage administrator working for a large enterprise is consolidating multiple locations into 2 data centers running on a new HCI platform. vSphere Replication has been used with vSAN to migrate a large amount of data between two separate locations with high latency links.

Which two statements are correct in this scenario? (Choose two.)

• A. vSphere replication does not add additional load to the Storage solution.
• B. When using vSphere Replication and vSAN, only virtual machines that are powered on are automatically replicated.
• C. vSphere Replication will automatically run a post-failover clean up task following replication being stopped.
• D. VMware Site Recovery Manager is required to perform the failover.
• E. There will be a post migration task to manually cleanup vSAN namespaces at the target data store.

Answer: A,C

• D. minimum of 4 vCPUs per node
• E. configure UEFI firmware

Answer: A,B

 

NEW QUESTION 28
Which is true about vSAN fault domains?

• A. Objects will be resynchronized when the Object Repair Timer expires.
• B. Resync Throttling has caused data resynchronization scheduling.
• C. Metadata resynchronization is scheduled to occur every 60 minutes.
• D. Offline host reconnected to the cluster and all objects are synchronized.
