VMware VMware Certifications 3V0-624 Questions & Answers

• Question 31:

  A customer is using blade servers with only one HBA.

  Which two design concepts apply to this scenario? (Choose two.)

  A. Assumption

  B. Risk

  C. Constraint

  D. Requirement

  Correct Answer: BC

  One HBA is a single point of failure and therefore a risk.Using this hardware configuration is a constraint (which although might also be a non-functional requirement

• Question 32:

  A customer has requested a high availability option for its data center in the event of power failure and the loss of connectivity to a virtual machine. Which three vSphere features support fault tolerance? (Choose three.)

  A. HA

  B. Virtual volume datastore

  C. vMotion

  D. Storage-based policy management

  E. DRS

  F. Virtual machine snapshots

  Correct Answer: ACE

  A, C, E are correct as in fact they are cluster requirements for FT

This process allows fault tolerant virtual machines to benefit from better initial placement." https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.avail.doc/GUID-59EA59EB-C60F-4815-AE2E-7A38506C516C.html

• Question 33:

  A customer uses vSphere Enterprise Plus edition and wants a network administrator to monitor network traffic. Which two capabilities help with monitoring network traffic? (Choose two.)

  A. Port Mirroring

  B. Network I/O Control

  C. QoS tagging

  D. NetFlow

  Correct Answer: AD

• Question 34:

  A customer is using a vSphere APIs for Storage Awareness (VASA) compatible storage array. The VASA provider is published as a virtual appliance. To ensure recoverability, where must the VASA prowler and vCenter server virtual machines be stored?

  A. The VASA provider and vCenter Server will be placed on the standard datastore (VMFS, NFS).

  B. The VASA provider and vCenter Server will be placed on the vVol datastore.

  C. The vCenter Server will be placed on the vVol datastore and the VASA provider will be placed on the standard datastore (VMFS, NFS).

  D. The VASA provider will be placed on the vVol datastore and the vCenter Server will be placed on the standard datastore (VMFS, NFS)

  Correct Answer: A

  A VASA VM should definitely not run on a vVol as it is then dependent on itself. Similarly, the VASA VM is dependent on vCenter, so both should be kept on a standard VMFS or NFS volume. If you have vCenter on a vVol, and both VASA VM and vCenter go down you are SOL.

  "You should not run VASA Provider on a VVOL datastore. Any management operation, including powering on a virtual machine that is on a VVOL, requires that VASA Provider be running. In addition, you would lose access to all VVOLs because VASA Provider would not be able to boot."

• Question 35:

  A company is consolidating its environment into vSphere 6.5, and uses a Fibre Channel SAN array to host a virtual machines.

  1.

  It has a pair of MSCS clustered VMs with shared RDM.

  2.

  High availability of service is its top priority.

  3.

  It wants to ensure that performance is optimized for the cluster service. The design requirements are:

  1.

  Storage should be able to withstand at least one component failure.

  2.

  Each server has at least 2 ports for FC connections.

  3.

  MSCS should also have no single point of failure with the clustering service. Which design will meet these requirements?

  

  A. Exhibit A

  B. Exhibit B

  C. Exhibit C

  D. Exhibit D

  Correct Answer: B

• Question 36:

  In the review of the current state of a business application, which three statements are true? (Choose three.)

  A. A virtual machine can be scaled up more quickly than a bare metal server.

  B. Application outages caused by known issues in the software do NOT count against the 99.9% SLA.

  C. Average latency should be monitored to ensure that application transactions never exceed 5 milliseconds.

  D. A weekly full backup and incremental every 2 hours meets an RPO of 2 hours.

  E. Separation of duties can be implemented using Role Based Access Controls (RBAC).

  Correct Answer: BCE

• Question 37:

  A system architect is building a design that includes three vCenter Server Appliances with 20 to 25 ESXi hosts each. The reliability of the environment is the top business priority because the company runs several applications that must be highly available.

  Which VMware solution provides the ability to centrally detect issues in the environment and resolve them?

  A. Set up a log collection and analysis engine such as VMware Log Insight and point all components of the vSphere environment to this engine.

  B. Enable the deactivated VMware Log Browser Service to capture and search logs in the vSphere Web Client.

  C. Use the new vSphere HTML5 client that provides multiple ways to detect and isolate issues in the environment.

  D. Use the vCenter Server Support Assistant as an easy way to create log bundles, then transfer them to VMware support for analysis and resolution.

  Correct Answer: A

• Question 38:

  DRS/HA cluster services depend on which two resources? (Choose two.)

  A. Management network

  B. vMotion network

  C. Network Time Protocol

  D. Domain Name Services

  Correct Answer: AB

• Question 39:

  A company provides critical financial and statistical data for several major banks.

  1.

  The company ensures that the bank's customer data is secure and that analytics data is available when needed.

  2.

  Customers rely on this data before making crucial business and financial decisions.

  3.

  Just a few minutes of downtime can result in loss of revenue and trust.

  4.

  To meet high-availability requirements, the company's IT infrastructure components must be redundant.

  5.

  The company established three data centers across the globe and interconnected them with high-speed WAN links.

  6.

  Due to the rapid growth of its customers and their increasing demands, the compute, network, and storage were procured and managed by the company's enterprise system administrators group.

  What are its two key challenges? (Choose two)

  A. Data centers across the globe possess manageability problems.

  B. Availability of business applications must be ensured.

  C. Regulatory requirements must be met.

  D. Hardware-defined data centers have limitations.

  Correct Answer: AD

  Read carefully: two key "challenges" NOT two key "requirements". Therefore A and D are correct, "challenges". If it said two key "requirements" then B and C would be correct.

• Question 40:

  A company has requested a new vSphere 6.5 design that will allow it to finally break the 80% virtualization barrier by virtualizing its resource-intensive application.

  1.

  The application is highly available by design and includes application-aware clustering software capable of operating as a fully distributed system.

  2.

  The company's Application Version 2.0 consists of 386 small applications and middleware with non-persistent storage and 24 database virtual machines at each data center.

  3.

  When coupled with a proper load balancing solution, this application can continue operating even with the loss of an entire data center, but the small applications and middleware tiers within a data center must exist within the same broadcast domain.

  4.

  The database tier is tightly controlled with a firewall policy that only allows middleware tier access, and is replicated to other sites using a dedicated circuit.

  Which two application requirements apply to this scenario? (Choose two.)

  A. The application will require the configuration of an IGMP stub and helper.

  B. Shared storage is required by the application clustering software.

  C. The application will require one large subnet.

  D. The application will require a method of balancing and recovering sessions between sites.

  Correct Answer: CD

  More than one subnet will be required in order to enforce firewall rules between the applications and databases. Also, one cannot determine if IGMP Stub and Helper are required without more information around the application.
