EMC E20-018 Online Questions & Answers

• Question 141:

  An application processes test results from a manufacturing facility, then generates and archives quality reports. The application has been in production for five years.

  The application was developed by an outsourced company that is no longer in business. The source code is not available. It can run on any current Microsoft Windows Server operating system.

  What is this an example of?

  A. Vendor lock-in
  B. A legacy application
  C. An enterprise application
  D. Service-oriented architecture
  A. Vendor lock-in

• Question 142:

  As part of a VDC deployment, you are examining the existing storage configurations. On one storage system, you discover over fifty storage pools. The pools contain a single type of drive (SSD, SAS or NL SAS), but many of them contain

  only a few drives and share the same RAID configuration. The Storage Administrator admits that they have been creating separate pools for each application because they did not want the applications contending for the disks.

  As part of the design, you propose to consolidate the existing pools into larger pools of mixed drive types and RAID configurations.

  What technology will you need to implement to utilize the new pool design?

  A. Virtual Provisioning
  B. Caching Tier
  C. Storage Virtualization
  D. Storage Tiering
  D. Storage Tiering

• Question 143:

  In the context of GRC, which are data handlers?

  A. Employees and contractors
  B. Service providers
  C. SAN components
  D. End users populating a web form
  A. Employees and contractors

• Question 144:

  Which mode of IPSec encrypts only the payload of the IP packet?

  A. Trusted
  B. Transparent
  C. Transport
  D. Tunnel
  C. Transport

• Question 145:

  Which type of switch can provide management functions for virtual machine ports?

  A. Distributed virtual switch
  B. Standard virtual switch
  C. Physical switch
  D. Third-party virtual switch
  D. Third-party virtual switch

• Question 146:

  A VDC administrator needs to create a virtual distributed file system. Which file storage protocol would best meet their requirement?

  A. iSNS
  B. pNFS
  C. NFS
  D. NTFS
  B. pNFS

• Question 147:

  A small law firm that does not currently have any virtualization technologies implemented has recently merged with another firm of approximately the same size. They are planning to consolidate into a single location. They have decided to virtualize their servers and they would like to consolidate storage. It has been determined that 80% of the file server data has not been accessed in over 90 days.

  What can they implement to achieve higher storage efficiency?

  A. A file archiving plan, to leverage inter-array storage tiering
  B. Quotas, to limit the amount of capacity users or groups can consume
  C. File extension filters, to prevent non-business related data from being stored in home directories
  D. Vertical storage tiering, to ensure data is placed on the appropriate drive technology
  A. A file archiving plan, to leverage inter-array storage tiering

• Question 148:

  Your client is considering a virtualized data center (VDC) as an investment in process improvement. A VDC can improve the delivery of which business process?

  A. Auditing
  B. Business continuity / disaster recovery
  C. Compliance
  D. Capacity planning / management
  D. Capacity planning / management

• Question 149:

  Which is a scale-out NAS solution that can distribute data over multiple nodes for resiliency?

  A. EMC VPLEX
  B. EMC Symmetrix VMAX
  C. EMC Isilon
  D. EMC VNX
  C. EMC Isilon

• Question 150:
