EMC Implementation Engineer E20-885 Questions & Answers

  • Question 241:

    A customer has an existing DR solution using SRDF between Symmetrix at their source and backup sites. TimeFinder Clones are also used at the backup site. A new VNX is installed at the backup site. The customer tries to use Incremental SAN Copy to copy data updates from the TimeFinder Clone to live web server LUNs on the VNX. The customer reports they are not able to configure the SAN Copy session. Why does the customer need to rework this solution?

    A. The source for Incremental SAN Copy must be a TimeFinder BCV, and the server I/O needs to be stopped.

    B. The source for Incremental SAN Copy must be on the VNX, and the server I/O needs to be stopped.

    C. The source for Incremental SAN Copy must be on the source Symmetrix, and TimeFinder Snapshot needs to be used.

    D. The source for Incremental SAN Copy must be on the VNX, and the data needs to be pushed.

  • Question 242:

    An Exchange 2010 environment with 60% reads and 40% writes will be configured on an EMC VNX using RAID 1/0 15K SAS drives. The total I/O per second required is 3,000. Accounting for additional overhead for spikes, what is the number of spindles required?

    A. 32

    B. 24

    C. 30

    D. 28

  • Question 243:

    A customer plans to virtualize their SQL databases on an EMC VNX. They are most concerned about database performance. How should they design the SQL layout?

    A. Distribute multiple SQL instances per VM

    B. Distribute one SQL instance per ESX server

    C. Distribute one SQL instance per VM

    D. Allocate all SQL instances to the VM with the most resources

  • Question 244:

    A customer plans to implement and replicate CIFS on two new EMC VNX. The customer's existing environment recently suffered a long outage due to a computer virus. The customer wants to use CAVA in their new CIFS environment on VNX. Which configuration will satisfy this requirement?

    A. Create a Global CIFS Server on the physical Data Mover at the primary and DR sites.

    B. Configure the CAVA client on the Virtual Data Mover at the primary and DR sites.

    C. Configure the CAVA client on the VNX Control Station at the primary and DR sites.

    D. Create a Global CIFS Server on the Anti-Virus Engine at the primary and DR sites.

  • Question 245:

    Two new EMC VNX were implemented at a customer's primary and backup sites. Each VNX has a single active Data Mover. Multiple VDMs are configured on both VNX, each with a CIFS file system. The default mapping solution was implemented in a primary-secondary configuration.

    The customer completes a security audit and then observes new user authentication fails on the secondary site. Which TCP/UDP port is being blocked by the firewall?

    A. 12345

    B. 443

    C. 23

    D. 8088

  • Question 246:

    A customer has vSphere v4.x hosts connected to an EMC VNX with thin provisioned pools. They report capacity shortages even after deleting or migrating some VMs. You recommend the customer upgrade their virtual environment to vSphere v5.0 to benefit from the new features and enhancements in VAAI. Which VAAI feature will address their issue?

    A. Dead Space Reclamation

    B. Thin Provisioning Stun

    C. Hardware Acceleration

    D. Hardware assisted locking

  • Question 247:

    Click on the calculator in the upper left-hand corner.

    A company plans to migrate their 10 TB Oracle 10g database to a new EMC VNX with FAST Suite and

    FAST Cache. What is the recommended minimum FAST Cache size that should be provisioned?

    A. 1 TB

    B. 500 GB

    C. 100 GB

    D. 200 GB

  • Question 248:

    You are deploying Exchange 2010 using a VMware virtualized infrastructure. A large VMFS partition will support the operating system binaries for four mailbox servers. RDM devices will be used for all database and log volumes. All partitions on the RDMs have been created using Windows Disk Manager.

    During deployment verification, you populate a database with test data and attempt to create a backup of it using Replication Manager. The replica creation fails with an error. What is the cause?

    A. The RDMs were created in virtual mode.

    B. The vSphere client was used to create the VMFS partitions.

    C. The ESX 'maxlun' parameter has been exceeded.

    D. Replication Manager does not support VMFS volumes.

  • Question 249:

    A customer configures SnapView clones on their EMC VNX. A 512 GB clone is fractured for 5 minutes. The source LUN performs fifty 16 KB random writes per second. The clone resynchronization is configured to 6 MB/s. How long will it take to resynchronize the clone?

    A. 21.0 minutes

    B. 35.0 minutes

    C. 10.5 minutes

    D. 60.0 minutes

  • Question 250:

    Exchange 2010 is installed on a virtual machine using VMDK files. Replication Manager is being used to

    take snapshots of the virtual machine files and back them up to disk. After a few weeks, the Exchange

    server stops functioning.

    What is the most likely reason for the Exchange failure?

    A. Replication Manager is unable to truncate log files.

    B. Replication Manager can only snapshot powered off VMs.

    C. Replication Manager is compatible with RDMs, not VMDKs.

    D. Replication Manager is not compatible with VMFS version 5.
