Question 6

A customer wishes to host a new range of applications with high-performance needs, specifically, low latency.
The applications are required to be hosted at company-owned edge locations, each with minimal rack space (three host slots per edge location for this project).
Which deployment options would satisfy the customer's needs, while maximizing the amount of capacity available per deployment?

A.A new three-node vSAN 8.0 All-Flash Cluster with OSA in each edge location Each application VM configured with a RAID-5 VM storage policy
B.A new three-node vSAN 8.0 All-Flash Cluster with OSA in each edge location Each application VM configured with a RAID-1 VM storage policy
C.A new three-node vSAN 8.0 All-Flash Cluster with ESA in each edge location Each application VM configured with a RAID-1 VM storage policy
D.A new three-node vSAN 8.0 All-Flash Cluster with ESA in each edge location Each application VM configured with a RAID-5 VM storage policy

Correct Answer: B

Explanation
To satisfy the customer's needs for high-performance, low-latency applications at edge locations, the best deployment option is to use a new three-node vSAN 8.0 All-Flash Cluster with OSA in each edge location and configure each application VM with a RAID-1 VM storage policy. This option will provide the following benefits:
All-flash clusters offer the highest performance and lowest latency for vSAN, as they use flash devices for both cache and capacity tiers. Flash devices have faster read and write operations than magnetic disks, and they also support advanced features such as deduplication, compression, and encryption.
OSA stands for One Socket Architecture, which means that each host has only one CPU socket with multiple cores. This reduces the licensing cost and complexity of vSphere and vSAN, as well as the power consumption and cooling requirements of the hosts. OSA also improves the performance of vSAN by eliminating the NUMA effect, which is the latency caused by accessing memory or devices across different CPU sockets.
RAID-1 is a mirroring technique that creates two copies of each data component and places them on different hosts. This provides high availability and fault tolerance for the application VMs, as they can survive the failure of one host or disk. RAID-1 also offers better performance than RAID-5 or RAID-6, as it does not incur any parity overhead or additional write operations.
The other options are not optimal for the customer's needs, as they either sacrifice performance or capacity.
Option A uses RAID-5, which is an erasure coding technique that splits each data component into three data segments and one parity segment, and distributes them across four hosts. This reduces the capacity consumption by 25%, but it also increases the write latency and network traffic, as each write operation requires four hosts to participate. Option C uses ESA, which stands for Enterprise Storage Architecture, which means that each host has two CPU sockets with multiple cores. This increases the licensing cost and complexity of vSphere and vSAN, as well as the power consumption and cooling requirements of the hosts.
ESA also introduces the NUMA effect, which can degrade the performance of vSAN by adding latency to access memory or devices across different CPU sockets. Option D uses RAID-5 with ESA, which combines the disadvantages of both options A and C.

Question 7

A vSAN administrator needs to enable vSAN ESA.
Which two requirements need to be met? (Choose two.)

A.vSAN Build Your Own configuration
B.vSAN Standard license
C.vSAN Witness Appliance
D.vSAN Advanced license
E.vSAN ReadyNodes configuration

Question 8

A vSAN administrator has a vSAN cluster that is using vSphere Lifecycle Manager (vLCM) to manage hypervisor, server drivers, and firmware. All hosts in the cluster are compliant according to the vLCM image.
A 10GB NIC on the servers is experiencing issues, and the vSAN administrator determines a new network driver will resolve the problem. Unfortunately, the required NIC driver is a newer version compared to the driver provided by the most recent Vendor Add-on.
Which action should the vSAN administrator take to ensure the latest network driver is installed on the NIC before remediation?

A.Make sure the vLCM image is configured to use the most recent version of the Vendor Add-on
B.Add an individual component to the vLCM image that has the updated NIC driver
C.Remove theVendor Add-on from the vLCM image, and then manually install the network driver on the servers
D.Modify the vLCM image to omit the NIC Driver, and then manually update the servers with the required NIC driver

Question 9

Refer to the exhibit.
An administrator uses SSH to log into a vSAN ESA host and runs theesxcli vsan debug object overview command.

The administrator notices the Healthy Components column, the last column, is reporting some components are not in a fully healthy state.
What could cause this behavior?

A.New physical disks have been claimed and a rebalance operation is underway.
B.The applied Storage policy has been updated.
C.New VMDKs have been added to multiple VMs, but the storage policy has not finished applying.
D.One host is in maintenance mode with ensure accessibility.

Question 10

A vSAN administrator wants to transition from VMware Update Manager to vSphere Lifecycle Manager.
Which element is a mandatory requirement to create an image?

A.ESXi Version
B.Component
C.Firmware and Drivers Add-On
D.Vendor Add-On
