EMC E20-018 Online Questions & Answers

• Question 61:

  An organization plans to migrate a single application from a traditional, physical infrastructure to new servers. These servers are the first of several planned for their VDC. This will be the pilot application for the VDC migration to be completed over the next 5 years. The project is well funded and the VDC has more than enough capacity to support the pilot application.

  Which migration strategy will they most likely use and why?

  A. A forklift approach, because they can keep the old systems running in parallel and they have the capacity to run in either the VDC or traditional data center as needed should something go wrong.
  B. A phased approach, because they can keep the old systems running in parallel and they have the capacity to run in either the VDC or traditional data center as needed should something go wrong.
  C. A forklift approach, because this allows them to re-purpose the old servers and add those resources to the new VDC immediately.
  D. A phased approach, because this allows them to re-purpose the old servers and add those resources to the new VDC immediately.
  A. A forklift approach, because they can keep the old systems running in parallel and they have the capacity to run in either the VDC or traditional data center as needed should something go wrong.

• Question 62:

  A VDC environment will be deployed with several virtual machines (VMs). The datastores for the VMs will be hosted on a storage array. Array-based local replication has been proposed as the BC/DR solution. Restore granularity will be at the individual VM level.

  What is the simplest data layout that would meet this requirement?

  A. A single large LUN for all virtual disks
  B. An individual LUN for all virtual disks of each VM
  C. All virtual disks on the boot LUN of the hypervisor
  D. An individual LUN for each virtual disk
  B. An individual LUN for all virtual disks of each VM

• Question 63:

  What capabilities are needed to transform a VDC into IaaS?

  A. Self-service portal, service catalog, metering processes
  B. Self-service portal, pay-as-you-go
  C. Metering processes, multi-tenancy, termination agreements
  D. Pay-as-you-go, service catalog
  A. Self-service portal, service catalog, metering processes

• Question 64:

  A company is thinking of deploying a new HR application to the public cloud.. However, they are concerned about the regulatory requirements. Several of the countries in which the company operates require that personal information not flow across country borders.

  What should the company do when it investigates cloud providers?

  A. Evaluate the cloud provider's architecture to ensure that it can satisfy regulatory requirements
  B. Accept the cloud provider's service-level agreement for specific protections regarding employee data
  C. Review the cloud provider's audit results to verify that it has never moved data across country borders
  D. Create a one-off contract with the cloud provider to specify handling of employee data
  A. Evaluate the cloud provider's architecture to ensure that it can satisfy regulatory requirements

• Question 65:

  A VDC administrator wants to implement a service to non-disruptively relocate virtual machines from one physical host to another physical host. Which service should they implement?

  A. Online Migration
  B. High Availability
  C. Distributed Switching
  D. Resource Pooling
  A. Online Migration

• Question 66:

  A company has virtualized all their non-mission critical applications and many of their mission critical applications. They now want to convert those virtualized silos that are still owned by the lines of business into a true VDC. What is an important technical capability gained from doing this?

  A. Provisioning time is reduced by deploying standard services
  B. A multi-tenant environment can be leveraged to deploy custom services
  C. The data center is ready to deploy cloud services
  D. Energy consumption is cut dramatically due to increased consolidation
  A. Provisioning time is reduced by deploying standard services

• Question 67:

  A small company asks you to design a VDC in each of their two data centers, using stretched VLANs and native Fibre Channel extension to interconnect the environments. The data centers are located 30 km apart. After inquiring with the local service providers, you find that only two strands of dark fiber are available.

  Which distance networking technology is the most appropriate?

  A. CWDM
  B. DWDM
  C. Dark Fiber
  D. MPLS
  A. CWDM

• Question 68:
