EMC E20-018 Online Questions & Answers

• Question 21:

  You are meeting with the CIO to discuss your VDC design. They question the amount of capital that is being invested in iSCSI adapters. They state that, because of the number of adapters required, it is more costeffective to purchase 10 Gigabit Ethernet NICs and use the integrated hypervisor software stack.

  What effect will this have on the design?

  A. Larger form-factor hypervisors will be required
  B. Fewer hypervisors will be required
  C. More hypervisors will be required
  D. Smaller form-factor hypervisors will be required
  C. More hypervisors will be required

• Question 22:

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

  What is the optimal data layout to meet this requirement?

  A. Individual LUNs for each virtual disk
  B. All virtual disks on the boot LUN of the physical disks
  C. Individual LUNS for each VMS virtual disk
  D. Single large LUN for all VM virtual disks
  C. Individual LUNS for each VMS virtual disk

• Question 23:

  An organization supporting 12,000 desktop PCs is considering implementing VDI. What is a benefit of moving forward with a VDI plan?

  A. Ease of addressing compliance issues
  B. Reduced impact on network infrastructure
  C. No change in desktop management methods and tools
  D. Immediate cost savings
  A. Ease of addressing compliance issues

• Question 24:

  You have a requirement to encrypt data that will be stored in several SAN-attached storage systems, including both disk arrays and tape libraries.

  Which

  solution would address this requirement?

  A. Cisco SME
  B. VMAX D@RE
  C. PowerPath/VE with RSA Encryption
  D. EMC VPLEX
  A. Cisco SME

• Question 25:

  An administrator is managing a virtualized environment that has limited available physical NICs on the hyper host. The hypervisor hosts physical switch ports are configured for VLAN tagging. A new application is being deployed that will need to be on a new subnet.

  What should the administrator implement to provide this new subnet for the application servers in the least amount of time?

  A. Add ports to an existing port group
  B. Add virtual switch to the hypervisor host
  C. Add a new port group with an individual VLAN
  D. Add network cards to the hypervisor host
  B. Add virtual switch to the hypervisor host

• Question 26:

  A company requires their application, which is running on a virtual server, to be continuously available. They would like to provide automatic failover and non-disruptive failure recovery. Which service should they configure?

  A. Fault Tolerance
  B. High Availability
  C. Online Migration
  D. Resource Pooling
  A. Fault Tolerance

• Question 27:

  An organization uses Linux desktops, laptops, and servers for their primary infrastructure. The company has a business need to run an application that is only available for the Microsoft Windows operating system. This application needs to be

  available to approximately one third of their 100 desktop and laptop users.

  There is concern about the stability of the application and how a single failure might impact multiple users in a shared environment.

  Which solution would best meet their needs, and why?

  A. VDI, because it provides true user segmentation
  B. RDS, because it allows all users to share a single instance of an application
  C. VDI, because it provides the highest density per user
  D. RDS, because it provides better fault tolerance
  A. VDI, because it provides true user segmentation

• Question 28:

  A customer is determining whether the risk involved in migrating in-house data to a third- party cloud provider is acceptable. Which step should be performed after the initial evaluation of the asset?

  A. Run a full risk assessment
  B. Leverage standards to mitigate risks
  C. Run a second asset evaluation
  D. Deploy the environment
  B. Leverage standards to mitigate risks

• Question 29:

  Which product eliminates the need to replicate data manually to a secondary file system?

  A. EMC Isilon
  B. EMC VFCache
  C. Cisco WAFS
  D. Cisco UCS
  A. EMC Isilon

• Question 30:

  After virtualizing an x86 server workload, users report that a custom application is performing poorly. You investigate the issue and find that the resources on the host do not appear to be constrained. However, you discover that the application on the guest operating system has an abnormally high number of context switches.

  What should you do to resolve the issue?

  A. Deploy additional hosts
  B. Move to a Type 2 hypervisor
  C. Use software-assisted virtualization
  D. Turn on hardware virtualization in the BIOS
  D. Turn on hardware virtualization in the BIOS
