VMware VMware Certifications 3V0-624 Questions & Answers

• Question 71:

  A company is conducting a technology refresh and has requested assistance with a vSphere 6.5 design.

  1.

  The company has a corporate headquarters and two data centers strategically placed around the country, which provide the bulk of the computer power and storage for their customer-facing stores.

  2.

  The company requires each of its stores to be able to operate independently if connectivity is ever lost.

  3.

  Presently, all stores are configured differently and must be standardized as part of the technology refresh

  4.

  To support store operations, only a dozen applications are required.

  5.

  Any downtime during store hours could result in significant losses.

  6.

  Any proposed design must minimize cost.

  What is a VMware-recommended option for this scenario?

  A. VMware vSAN cluster with a minimum of three hosts

  B. VMware vSphere cluster with low-cost iSCSI shared storage

  C. VMware vSAN Stretched Cluster with nearest regional data center

  D. VMware vSAN Remote Office Branch Office (ROBO) with two hosts

  Correct Answer: D

  Reference: https://www.vmware.com/files/pdf/products/vsan/vmware-vsan-robo-solution-overview.pdf "The use of a virtual appliance as a witness host eliminates the need to deploy a third physical server, whichreduces the overall cost of the solution without sacrificing the benefits of shared storage." "By default, a replica isplaced on each host of the 2-node configuration. If one of the physical hosts is offline, it is still possible forvirtual machines to run using replicas located on the other physical node. In the case where the hosts in a 2

  node cluster are unable to communicate across the network, the witness host serves as a "tie-breaker" toachieve a quorum and maintain data accessibility and integrity." VSAN Robo satisfies requirements 2,5,6.

• Question 72:

  A company has requested that a new vSphere 6.5 design be created.

  1.

  The existing environment consists of 32 vSphere 6.0 hosts attached to an iSCSI storage array.

  2.

  The storage arrays contain external customer financial and medical records used by the company's investment and medical services division.

  The design must:

  1.

  protect the company's existing data center investment

  2.

  expand to a second data center site

  3.

  introduce process automation

  4.

  expand to and fail over to public cloud

  Which two non-functional requirements are applicable for this design? (Choose two.)

  A. The product of the design must account for regulatory compliance.

  B. The automation solution must be compatible with the existing equipment.

  C. The product of the design must feature 3DES encryption at the virtual machine disk level.

  D. At least two 10Gbps interfaces must be dedicated to storage on each host.

  E. Every host in the design must have Lockdown Mode enabled for security.

  Correct Answer: DE

• Question 73:

  A customs has requested a vSphere 6.5 deployment design where ESXi hosts are provisioned with Auto Deploy. The customer requires that certificates can be automatically refreshed and renewed from the vSphere Web Client for ESXi hosts.

  Which certificate policy should be configured for vCenter Server?

  A. Thumbprint Mode

  B. VMware Certificate Authority

  C. Custom Certificate Authority

  D. Subordinate Certificate Authority

  Correct Answer: B

  "If VMCA assigns certificates to your ESXi hosts (6.0 and later), you can renew those certificates from the vSphere Web Client. You can also refresh all certificates from the TRUSTED_ROOTS store associated with vCenter Server"

• Question 74:

  A solution architect has finished conducting interviews and gathering requirements for a company, and has determined that the logical requirements are:

  1.

  two data centers for high availability

  2.

  synchronous replication to meet the zero minute RPO

  3.

  separating management workloads from application workloads

  4.

  dedicated 10Gb uplink for each low latency server

  5.

  single management port for the entire environment

  Which two actions would meet the design requirements? (Choose two.)

  A. Create two data center objects in vCenter Server.

  B. Configure vSAN Stretched Clustering.

  C. Configure SR-IOV for low latency servers.

  D. Create one folder for Management workloads and one folder for application workloads.

  Correct Answer: BD

  Folders don't separate workloads (management object only) and Zero-RPO implies vSAN stretched cluster. Even though thee vSAN nodes are at different sites, they must reside within one logical data center in vCenter (and inside a single Cluster Object).

• Question 75:

  A solution architect has finished conducting interviews and gathering requirements for a company, and has determined that the logical requirements are:

  1.

  two data centers for high availability

  2.

  3.

  separating management workloads from application workloads

  4.

  dedicated 10Gb uplink for each low latency server

  5.

  single management point for the entire environment

  Which two actions would meet the design requirements? (Choose two.)

  A. Configure 1 Port Group with a dedicated 10Gb Uplink for low latency servers.

  B. Deploy two clusters, one for management workloads and one for application workloads.

  C. Build 2 Port Groups, one for management serves and one for application servers.

  D. Install two vCenter Servers in Enhanced Link Mode.

  Correct Answer: AC

• Question 76:

  The hardware operations team is planning to purchase new ESXi hosts for the upcoming budget year and is requesting recommendations on the type of servers to purchase for a web application. The web application consists of hundreds of small virtual machines (1 vCPU and 8GB of RAM) that are members of a software cluster.

  The solution should have these abilities:

  1.

  recover from ESXi host hardware failures

  2.

  zero downtime for a limited number of critical virtual machines (VMs)

  3.

  migrate running VMs between ESXi hosts without interruption to the operating system

  4.

  perform these functions using VMware ESXi servers, vCenter Server, and high-speed network interfaces

  What are the three functional requirements and their associated VMware technologies? (Choose three.)

  A. automatic restarts of failed VMs (vSphere HA)

  B. high speed network interfaces (vSphere Distributed Switches)

  C. ability to migrate running VMs (vSphere vMotion)

  D. fault tolerance for limited number of critical VMs (vSphere FT)

  E. VMware ESXi Servers (vSphere Auto Deploy)

  Correct Answer: ACD

  They need vSphere HA to recover VM's (web applications) from hardware failure.

  They need vMotion to move VM's between hosts without interruption to OS.

  They need zero downtime of Fault Tolerance (Supports up to 4 vCPU and 64GB RAM on 6.5) to support critical VM's.

  There is no mention of a need for Distributed Switches (Standard Switches would meet requirements) and no mention of requirements for deployment of ESXi (Auto Deploy).

• Question 77:

  A company is implementing a new ESXi host cluster at its New York data center.

  1.

  The CIO has stated that the new ESXi cluster should be deigned with enough failover capacity to sustain two ESXi host failures.

  2.

  Six ESXi hosts have been approved for this workload.

  3.

  The ESXi hosts are to be purchased from Dell with these specifications:

  4.

  2x10 core 2.2GHz Intel CPU

  5.

  128 GB of memory

  6.

  The workload is defined as 150 employee desktop virtual machines each with 3GB RAM reserved.

  7.

  All virtual machines should be protected by vSphere High Availability

  Which are two true statements regarding failover capacity? (Choose two.)

  A. vSphete HA can be configured to reserve 25% of memory capacity for failover.

  B. vSphete HA can be configured to specify two dedicated failover hosts.

  C. vSphere HA can be configured to reserve 35% of memory capacity for failover.

  D. vSphere HA can be configured to specify one dedicated failover host.

  Correct Answer: BC

  You have the option in vSphere HA to reserved any number of hosts /or % of memory resources (1/3 = ~35%).

  These both enforce the CIO requirements.

  A) Memory reserved is not enough to sustain 2 hosts failure

  B) Yes, requirements are to sustain 2 hosts failure. Dedicating 2 hosts would leave a total usable memory of 512 GB, which is enough to cover 450GB of VMs memory.

  C) Yes, if you want to sustain 2 hosts failure you need to reserve the same amount of memory contribution of those hosts. In this case, 2 hosts out of 6 it's 1/3 = 33.3%. So rounding up to 35% is correct.

  D) No, solution needs to sustain 2 hosts failure
