Which of the following diagrams which may be included in project documentation shows a system's components and how they could affect/depend on each other?

  1. Logical diagram
  2. Entity relationship diagram
  3. Physical diagram

Answer(s): B

Explanation:

An entity relationship diagram is a form of logical diagram than can be used to map service component dependencies. It is independent of the hardware used for a solution. Chapter 2, Presenting the Data Gathered



Infrastructure qualities are guiding design considerations that can be used . (Choose two)

  1. in the absence of project requirements
  2. instead of project requirements
  3. in addition to project requirements

Answer(s): A,C

Explanation:

Good design should meet the project requirements and consider the properties of assumed platform design. Protecting data requires that a system be available and manageable, that it have good performance, and that it be easy to recover and be secure. Chapter 3, What Makes a Good Choice for Virtualization, and What Is a Good Design?



In a stateless Auto Deploy design, which of the following is correct?

  1. The vCenter has a direct impact in the event of an outage of this component.
  2. The Auto Deploy server has a direct impact in the end of an outage of this component.
  3. Both of the above statements are correct

Answer(s): C

Explanation:

The Auto Deploy feature is an excellent design choice for managing a mass installation of ESXi. The vCenter is required for implementation; however, the requirement is independent of vCenter version. Chapter 4, Management/Platform Design



VMware HA can reduce the requirement for disaster recovery planning and documentation.

  1. True
  2. False

Answer(s): B

Explanation:

VMware HA can satisfy the majority of RTO scenarios. In general, a business can tolerate small outages of less than a few minutes. When designed correctly, HA can satisfy this requirement while providing hardware-level protection. Chapter 4, The Importance of vMotion, VMware HA, and Fault Tolerance



You are tasked with ensuring that a multitier application will restart correctly during an HA event. Which of the following is required? (Choose two)

  1. A specified restart priority for each machine in the application tiers
  2. A vApp object
  3. A DR and validation process for operations staff manual processes

Answer(s): A,C

Explanation:

A vApp is a logical container for guest virtual machine objects. When you use a container, you have the ability to use key management functionality, which can dramatically help a virtualized platform. Automation allows a small number of staff to manage lots of virtual machines. Chapter 5, vApps



Before the implementation phase of a project, all design choices should be .

  1. validated and justified to the business and project team members
  2. documented, validated, and verified as vendor-based best practices
  3. validated

Answer(s): A

Explanation:

The best validation is to place a platform under a typical test of what it will be faced with in the field--for example, having a simulated number of users go through a workflow (perhaps a website). A lot of these tasks vary with the type of application and are primarily application functionality based. In addition, platform or infrastructure metrics are key for validation and for information to be used within the operational documentation (for example, troubleshooting guide, monitoring recommendations).
Chapter 6, Validation, Thoughts, and Processes



You have been asked to review a vSphere HA design. The admission control policy is set to "The number of host failures tolerated." The virtual machines vary in size, and use of VM-based reservations is common. Which of the following should be recommended? (Choose three)

  1. The platform has reservations removed unless specifically required by an application vendor verified or workload verified requirement.
  2. The platform should be configured with reservations based on resource pools
  3. The platform should be configured with an appropriate slot size or the admission control policy changed to a percentage based policy.
  4. The platform should not be configured with reservations based on resource pools

Answer(s): A,B,C

Explanation:

An admission control policy tells VMware HA how to calculate the resources it needs to reserve for a cluster. It uses a combination of memory and CPU reservation configuration or, if no configuration exists, a default low reservation. Chapter 4, The Importance of vMotion, VMware HA, and Fault Tolerance



When given a project requirement for RTO to be satisfied, VMware HA can be used with admission control enabled.

  1. True
  2. False

Answer(s): A

Explanation:

An admission control policy tells VMware HA how to calculate the resources it needs to reserve for a cluster. It uses a combination of memory and CPU reservation configuration or, if no configuration exists, a default low reservation. Chapter 4, The Importance of vMotion, VMware HA, and Fault Tolerance
