2: Recommend completing the latest Hands-On Lab(s) for vSAN.
3: Recommend attending VMware vSAN: Deploy and Manage [V6.6] course. Note: This training is strongly recommended, though not required.
4: Review the VMware vSAN 2017 Specialist Exam (2VB-601) Exam Prep Guide knowledge and objectives.
5: Pass the VMware vSAN 2017 Specialist Exam (2VB-601).

Objectives: By the end of the course, you should be able to meet the following objectives:
• Describe the vSAN architecture
• Identify vSAN features and use cases
• Configure vSAN networking components
• Configure a vSAN cluster
• Deploy virtual machines on a vSAN datastore
• Configure virtual machine storage policies
• Perform ongoing vSAN management tasks
• Outline the tasks for upgrading to vSAN 6.6
• Configure vSAN encryption
• Control vSAN resynchronization tasks
• Create and manage nested fault domains
• Use the vSAN health service to monitor health and performance
• Configure a stretched cluster and observe failover scenarios
• Describe vSAN interoperability with VMware vSphere® features and other products
• Plan and design a vSAN cluster

Intended Audience: Storage and virtual infrastructure administrators who want to use software-defined storage with vSAN

Prerequisites: This course requires completion of one of the following prerequisites:
• Storage administration experience on block or file storage devices
• Understanding of concepts presented in the VMware vSphere: Install, Configure, Manage [V6.5] course

Experience working at the command line is helpful.

The course material presumes that a student can perform the following tasks with no assistance or guidance before enrolling in this course:
• Use VMware vSphere® Web Client
• Create and manage VMware vCenter Server® objects, such as data centers, clusters, hosts, and virtua machines
• Create and modify a standard switch
• Connect a VMware ESXi™ host to NAS, iSCSI, or Fibre Channel storage
• Create a VMware vSphere® VMFS datastore
• Use a wizard or a template to create a virtual machine
• Migrate a virtual machine with VMware vSphere® vMotion®
• Migrate a virtual machine with VMware vSphere® Storage vMotion®

If you cannot complete all of these tasks, VMware recommends that you complete the VMware vSphere: Install, Configure, Manage [V6.5] course before enrolling in VMware vSAN: Deploy and Manage.

QUESTION 1
The following are the configuration details of a 12-node all-flash VSAN cluster:
Which two methods can be used to increase the size of the cache tier in each host? (Choose two.)

A. Promote a capacity device to a cache device so that each disk group has two cache devices.
B. Add a new cache device to the host. Reconfigure the host to have two disk groups with one cache device and three capacity devices per disk group.
C. Add asecond cache device to each disk group.
D. Replace the existing cache device in each disk group with a larger cache device.

Answer: C,D

Explanation:
As you create disk groups on each host and add cache and capacity devices, the size of the data store increases according to the amount of physical capacity added by those devices.
Typically, you delete devices or disk groups from vSAN when you are upgrading a device or replacing a failed device, or when you must remove a cache device.

QUESTION 2
An administrator is designing a vSphere cluster with the VSAN default policy. The requirement is to maintain full redundancy of data and virtual disks during any patching or maintenance of this cluster.
What is needed to meet the needs of this scenario?

A. A minimum of four hosts in the cluster
B. VMware Proactive HA
C. Multiple disk groups per host
D. Use of RAID-5/6 erasure coding

Answer: B

Explanation:
Patching a vCenter High Availability Environment
You can patch a vCenter Server Appliance which is in a vCenter High Availability cluster by using the
<codeph>software-packages</codeph> utility available in thevCenter Server Appliance shell.

QUESTION 3
Which two factors below determine how a VMDK object will be split on a vSAN cluster? (Choose two.)

A. Checksum parameter
B. Free capacity in the cache tier devices
C. Size of the VMDK object
D. Stripe width parameter
Answer: C,D

Explanation:
Note: Number Of Disk Stripes Per Object, commonly referredto as stripe width, is the setting that defines the minimum
number of capacity devices across which each replica of a storage object is distributed.

QUESTION 4
Given a limited maximum queue depth, what can an administrator do to potentially improve performance when deploying vSAN iSCSI volumes?

A. Utilize multiple iSCSI targets.
B. Change the erasure coding to RAID-6
C. Adjust the maximum iSCSI queue depth values
D. Configure multiple VMkernel ports

Answer: C

Explanation:
Today if you are noticing that your device queues are constantly bumping up to their maximum limits, it would be recommended to increase the Device/LUN depth and use SIOC to help mitigate any potential noisy neighbor problem.

QUESTION 5
Which are two functions of software checksums in a vSAN environment? (Choose two.)

A. Limit the number of IOPS that an object can consume
B. Perform disk scrubbing in the background
C. Limit the number of reads to the capacity tiered disks
D. Automatically detect and resolve silent disk errors

Answer: B,D

Explanation:
Software checksums which will perform the following checks:
