An architect will be taking over control of a former Linux server fleet and repurposing the hardware into a new vSphere cluster. The current environment is already connected to the network but the hosts do not have any local disks. Since the fleet hardware is uniform, the architect can use a single ESXi image. All hosts within the cluster have the same CPU and memory capacity.

Which ESXi deployment method should the architect use?

Stateless cached vSphere Auto Deploy
Stateless cached vSphere Auto Deploy
Stateless vSphere Auto Deploy
Stateless vSphere Auto Deploy
Manual install of each ESXi host with an image from USB
Manual install of each ESXi host with an image from USB

An architect is finalizing the design for a new vCenter Server High Availability deployment.

What is one thing the architect must document in the design?

The load balancing algorithm used by the Management Distributed Virtual Switches (DVS)
The load balancing algorithm used by the Management Distributed Virtual Switches (DVS)
The SSH configuration settings for the vCenter Server’s active node
The SSH configuration settings for the vCenter Server’s active node

The vCenter Management Network IPv4 addresses for the witness node vCenter Server
The details of each of the vCenter Server licenses for active, passive and witness nodes
The details of each of the vCenter Server licenses for active, passive and witness nodes
Suggested answer: B

Explanation:

vCenter HA uses SSH keys for password-less authentication between the Active, Passive, and Witness nodes. The authentication is used for heartbeat exchange and file and data replication. To replace the SSH keys in the nodes of a vCenter HA cluster, you deactivate the cluster, generate new SSH keys on the Active node, transfer the keys to the passive node, and activate the cluster. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-B8E590BA-ACF4-48A1-8644-E492D2241031.html https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-5F7DAFB2-60BD-4C50-A7E5-29A319CBB714.html

Automated initial virtual machine placement

Virtual Machine Resource Profile 2

Memory sharing techniques should not be used

Virtual machines should be automatically restarted in the event of host failure regardless of available resources

All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster One.
All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster One.
All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster One.
All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster One.
All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Two.
All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Two.
All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster Two.
All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster Two.
All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Three.
All virtual machines matching Virtual Machine Resource Profile 2 should be placed on Cluster Three.
Suggested answer: D, E

Explanation:

PVLANs divide the broadcast domain into multiple broadcast sub-domains and allow further isolating different devices within the same VLAN. They provide layer 2 isolation between ports within the same broadcast domain. For example: 'Your ESXi host uses several networks. Use appropriate security measures for each network, and isolate traffic for specific applications and functions. For example, ensure that VMware vSphere vMotion traffic does not travel over networks where virtual machines are located. Isolation prevents snooping. Having separate networks is also recommended for performance reasons.' https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-esxi-vcenter-server-70-security- guide.pdf

An architect is designing a new VMware solution for a customer that has a number of different resource profiles.

The following are the business requirements for the design:

The solution must support virtual machines with the following storage profiles:

- Write-intensive

- Backup

- Write-Once-Read-Many (WORM) archive

The solution must support migration of virtual machine disks between storage profiles.

The WORM archive data must be located at an isolated secure site.

The backup storage array must only be connected to a backup media server.

All data should be recoverable from backup.

Which design decision should the architect make to meet the business requirements?

The solution will leverage a single storage array for the WORM archive and write-intensive storage profiles
The solution will leverage a single storage array for the WORM archive and write-intensive storage profiles
The solution will leverage the same array for the backup and write-intensive storage profiles

An architect is preparing a design for a company planning digital transformation. During the requirements gathering workshop, the following requirements (REQ) and constraints (CON) are identified:

REQ01 The platform must host different types of workloads including applications that must be compliant with internal security standard.

REQ02 The infrastructure must initially run 100 virtual machines.

REQ03 Ten of the virtual machines must be compliant with internal security standard.

REQ04 The internal security standard specifies logical network separation for in-scope applications.

CON01 The customer has already purchased the licenses as part of another project.

CON02 The customer has five physical servers that must be reused.

Additionally, based on resource requirements, four physical servers will be enough to run all workloads. Which recommendation should the architect make to meet requirements while minimizing project costs?

Use Network I/O Control to ensure the internal security zone has higher share value
