NEW QUESTION # 27
An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the "Full-data migration" option.
What will happen after this action is taken?
- A. The system will prompt to add an additional host to the cluster in order to preserve the policy compliance.
- B. The host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.
- C. The host will enter in maintenance mode and only data with no redundancy will remain accessible.
- D. The host will enter into maintenance mode if both components of a certain object are residing on that host, then one of the components will be moved to another available host.
Answer: A
Explanation:
https://blogs.vmware.com/virtualblocks/2020/02/06/what-happens-vsan-host-in-maintenance-mode/ Let's take a look at a few unique scenarios with regard to maintenance mode. First, let's see what will happen if you have 6 hosts within your cluster, you have applied a policy containing FTT=2/RAID-6, and you want to place a host in maintenance mode using the 'Full data migration' option. This means all the data residing on the host will be evacuated to another host within the cluster. With this type of data configuration, the system will prompt you to add an additional host to the cluster in order to preserve the policy compliance. The policy will always require there must be two failures that can be tolerated, even during cluster reduction due to maintenance mode removing a host. Note that a minimum of six hosts is required to support a storage policy with RAID-6(FTT=2) erasure coding

NEW QUESTION # 31
A failed storage controller has two vSAN disk groups attached. The components contained on the dnves in those disk groups are marked Degraded. vSAN reports that some objects do not comply with their assigned storage policy.
How is the compliance issue resolved?
- A. Rebuilding of the degraded components starts immediately.
- B. Initiate a proactive rebalance to force component repairs.
- C. Storage policies must be reapplied to all affected objects.
- D. Degraded components are repaired after CLOM Repair Delay Timer expires.
Answer: A
NEW QUESTION # 32
An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.
Why is this behavior being seen?
- A. vSAN proactive tests haven't been run yet.
- B. vSAN network diagnostic mode is not enabled.
- C. vSAN performance service is turned off.
- D. vSAN performance verbose mode is not enabled.
Answer: C
Explanation:
Some tools allow for measuring latency peaks. This unfortunately isn't ideal, as it can unfairly represent statistical outliers, which may very well occur when there is little to no I/O activity. The best way to understand the actual behavior of VM and application latencies is to observe in time based performance graphs. Depending on the level of detail, you may need to measure at the individual VMDK level. Become familiar with these graphs to determine what is normal, and what is not for that given application. This is where you can use built-in functionality of vCenter and the vSAN performance service metrics to gather this information.

An administrator is tasked with preparing for a Cross vCenter migration in a stretched vSAN cluster where the virtual machines migration will be orchestrated via VMware Site Recovery Manager. Which action should the administrator take so the migration is successful?
- A. Reconfigure vCenter HA Admission control
- B. Disable vSAN Deduplication and Compression
- C. Enable vCenter Single Sign-On Enhanced Linked Mode
- D. Make sure that Witness traffic is on the management NIC.
Answer: C
Explanation:
Stretched storage is supported only on vCenter Single Sign-On Enhanced Linked Mode environments. Planned migration with Cross vCenter Server vMotion fails if the sites are not Enhanced Linked Mode. Stretched storage is required when using Cross vCenter Server vMotion during a planned migration.

NEW QUESTION # 42
A customer is planning to deploy a vSAN cluster to host their in-house distributed ERP system.
The hardware specifications for their server nodes include:
* 2 x Intel Xeon CPU E5-2697 v3 @ 2.60GHz
* 1TB memory
Which boot device is supported for the vSAN ESXi nodes for this customer?
- A. A 16GB single-level cell (SLC) SATADOM device must be used.
- B. A 16GB multiple-level cell (MLC) SATADOM device must be used.
- C. A 4GB USB or SD device must be used.
- D. ESXi Hosts must boot from a PMEM device.
Answer: A
Explanation:
If the memory of the ESXi host has 512 GB of memory or less, you can boot the host from a USB, SD, or SATADOM device.
If the memory of the ESXi host has more than 512 GB, consider the following guidelines.
You can boot the host from a SATADOM or disk device with a size of at least 16 GB. When you use a SATADOM device, use a single-level cell (SLC) device.
