Suggested answer: D, E

Explanation:

Two characteristics of the vSAN Data-At-Rest Encryption (DARE) are that it is Software Defined and works independently of the Cache or Capacity drives installed on the Nodes, and it continues to operate unaffected during downtime on vCenter Server. According to VMware's Official Guide, "vSAN Data-At-Rest Encryption (DARE) is a software-defined solution that works independently of the Cache or Capacity drives installed on the Nodes". Additionally, "DARE continues to operate unaffected during downtime on vCenter Server". Thus, these two characteristics make DARE an ideal encryption solution for vSAN.

A vSAN administrator has two identical VMware vSAN clusters, one for staging workloads and another for production workloads. Due to an unforeseen capacity requirement, the vSAN administrator is tasked with merging the staging vSAN cluster into the production.

Which two actions should the vSAN administrator perform on the staging cluster prior to moving the vSAN nodes to the production cluster? (Choose two.)

Answers
Suggested answer: B, D

Explanation:

The two actions that the vSAN administrator should perform on the staging cluster prior to moving the vSAN nodes to the production cluster are to disable vSAN Services and delete all Disk Groups.

According to VMware's Official Guide, "before removing the nodes from the source cluster and adding them to the destination cluster, you must disable vSAN services on the source cluster".

Additionally, "before merging clusters together, you must delete all disk groups in the source cluster".

This will ensure that the nodes can be successfully moved to the production cluster without any errors or conflicts.

Explanation:

PowerCLI is a command-line interface for managing VMware vSphere, vSAN and other VMware products. RVC is the Ruby vSphere Console which is an interactive command-line tool for managing vSphere, vSAN, and other VMware products. Using PowerCLI and RVC, you can run commands to identify unassociated objects and take corrective action. For example, you can use PowerCLI to list all vSAN objects and RVC to perform a check on the objects to see if they are unassociated.

An administrator is responsible for managing a 5-node vSAN 7.0 cluster. The vSAN Cluster is configured with both vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). The vSAN Cluster is currently hosting 150 virtual machines that have consumed 60% of the usable capacity.

Each virtual machine belongs to one of the following vSAN Storage Policies: vSANPolicy1:

• Site Disaster Tolerance: None

• Failures to Tolerate: 1 failure - RAID5 (Erasure Coding) vSANPolicy2:

• Site Disaster Tolerance: None

• Failures to Tolerate: No data redundancy

Following an unplanned power event within the data center, the administrator has been alerted to the fact that one host has permanently failed.

What will be the impact to any virtual machine that was running on the failed host using vSANPolicy1?

A.
Each virtual machine must be restored from backup.

D.
Each virtual machine will be restarted on another vSAN host using vSphere HA.
Answers
Suggested answer: C

Explanation:

The impact to any virtual machine running on the failed host using vSANPolicy1 will be that each virtual machine will be unavailable for up to 90 minutes while the automatic recovery process completes. vSAN will detect the failed disk and begin the automatic recovery process immediately.

During the process, any data stored on the failed disk will be reconstructed using the data stored on other disks in the cluster. This process can take up to 90 minutes to complete, during which the virtual machines will be unavailable. Once the recovery process is complete, the virtual machines will be restarted on another vSAN host using vSphere HA.

D.
No data protection will be applied to the VM objects.
Answers
Suggested answer: C

Explanation:

When a virtual machine is deployed on a vSAN datastore, it must be assigned at least one storage policy. If the administrator did not explicitly assign a storage policy when provisioning the new VM, vSAN will apply the vSAN Default Storage Policy to the virtual machine. The vSAN Default Storage Policy is a pre-configured storage policy that is automatically applied to virtual machines when no other storage policy is assigned.

According to VMware's official guide, "If a storage policy is not explicitly assigned to a virtual machine when it is provisioned, the virtual machine objects will be protected based on the vSAN Default Storage Policy configurations." This means that the vSAN Default Storage Policy will apply to the VM objects even if the administrator did not explicitly assign a storage policy when provisioning the new VM.

Answers
Suggested answer: D, E

Explanation:

According to VMware's official guide, the vSAN Data Persistence platform uses two storage policy types: Shared Nothing Architecture and vSAN Direct Configuration. Shared Nothing Architecture is a policy type that enables virtual machines to share a common storage pool and enables applications to scale out across multiple nodes. vSAN Direct Configuration is a policy type that allows applications to be deployed directly on the vSAN datastore and enables them to use the underlying vSAN storage features.

A vSAN administrator is planning to deploy a new vSAN cluster with these requirements:

• Physical adapters share capacity among several traffic types

• Guaranteed bandwidth for vSAN during bandwidth contention

• Enhanced security

E.
Isolate vSAN traffic in a VLAN
Answers
Suggested answer: B, E

Explanation:

According to VMware's official guide, Network I/O Control (NIOC) should be utilized in order to share the physical adapters' capacity among several traffic types. Additionally, isolating the vSAN traffic in a VLAN will provide enhanced security, as it isolates vSAN traffic from the rest of the network traffic.

Enabling jumbo frames and creating static routes between the vSAN hosts will not provide the desired result, as these are not related to the requirements. Utilizing IOPS Limit rules in storage policies is also not related to the requirements, as this is related to storage policies and not network configuration.

Suggested answer: C

Explanation:

When a cache disk is removed from a disk group in a vSAN cluster, the disk group goes offline. This means that the disk group is not available for use and the data stored on it is not accessible. This is done to prevent data corruption and to ensure the integrity of the data stored on the vSAN.
