• Question 301:

  You have implemented a VNX SnapSure schedule on a production file system. After a few days, the storage administrator complains that CIFS users accessing the snapshot need to remap the share around the same time each day. NFS users are able to successfully access the same snapshot with no interruptions. What could be the cause of the dropped links?

  A. A network interruption has occurred

  B. SavVol was not auto-extended

  C. The snapshot is being refreshed by the schedule

  D. SavVol has reached a full state

  Correct Answer: C

• Question 302:

  You are using the USM install Disk Array Enclosure wizard to add a DAE enclosure to a VNX system. What is the maximum number and type of DAE enclosure that the system can have?

  A. A combination of eight 2U 25-drive DAE5S enclosures and 3U 15-drive DAE6S enclosures

  B. It is based on the maximum number of drives

  C. Six 2U 25-drive DAE5S enclosures

  D. Eight 3U 15-drive DAE6S enclosures

  Correct Answer: B

• Question 303:

  An administrator has installed a new VNX and configured an interface using IP address 10.10.10.50 for CIFS file sharing over 10 gigabit Ethernet link. The administrator has also created two CIFS servers:one for production one for testing. They are currently able to access only the production CIFS server.

  What is the most likely source of this problem?

  A. A firewall is interfering with traffic to test network

  B. Only one CIFS server is supported per interface

  C. No route to the test network is currently avaiable

  D. The CIFS server used for testing needs to join the domain

  Correct Answer: B

• Question 304:

  A. PKCS#10

  B. X.500

  C. PKCS#12

  D. PEM

  Correct Answer: D

• Question 305:

  A VNX SnapSure snapshot has recently been created on a production file system (PFS). The second block in the PFS will be modified for the second time. How will SnapSure handle me bitmap value for this file system update?

  A. it remains unchanged; PFS is updated

  B. It remains unchanged; SavVol updated

  C. It is changed to 1;SavVol is updated

  D. Lt is changed to 1; SavVol is updated

  Correct Answer: A

• Question 306:

  Which is a requirement for moving a VDM from one physical data mover to another?

  A. At least one source VDM file system can be seen by the target Data Mover

  B. Interface names on the source and target Data Movers must be identical

  C. The VDM should be in an unloaded state in order to move it to the target Data Mover

  D. The target data mover must have at least one CIFS server with the same name as the source VDM

  Correct Answer: B

• Question 307:

  An administrator wants to add storage capacity to the cmsas_archive storage pool. They bind on new RAC

  for VNX for File and create a disk volume on the host from it. They check the cmsas_archive storage pool

  but potential capacity is not increased.

  What could be a possible cause?

  A. The cmsas_archive pool was not manually extended with the newly created di sk volume

  B. Disk volumes were not added to system-defined storage pools.

  C. The disk volume is already assigned to the same storage pool but it is still unused

  D. There is a mismatch between cmsas_archive disk volumes and the newly created disk volume type

  Correct Answer: D

• Question 308:

  An administrator wants to set an Export Permission on an NMFS. What is a key consideration concerning the export permissions on the component file system.

  A. The component file system does not inherit WFS export permissions

  B. The component file system cannot be assigned individual export permissions

  C. Export Permission of the component file system override NMFS export permission.

  D. Inherited NMFS export permissions override the component file system export permissions

  Correct Answer: D

  Explanation:

  A component (nested) file system will get it's permissions one of two ways:

  The user can export the component file system separate from the NMFS file systemand give it

  permissions at that time.

  The user can export just the NMFS file system. The component file systems then inherit the

  permissions from the parent (NMFS) file system.

• Question 309:

  You are provisioning a LUN on a VNX array with FAST VP enabled. In addition to Highest Tier Available and Lowest Tier Available, what other tier option(s) is displayed?

  A. Auto-Tier, No Data Movement

  B. Optimize for Performance

  C. Auto-Tier

  D. Optimize for Performance, No Data Movement

  Correct Answer: C

  Explanation:

  

• Question 310:

  Which tools can be used to configure IPv6 on an installed VNX Control Station that was initially configured as IPv4?

  A. Unisphere and CLI only

  B. CLI and VNX Installation Assistant only

  C. Unisphere and VNX Installation Assistant only

  D. Unisphere, CLI, and VNX Installation Assistant

  Correct Answer: A

  Explanation: The VNX Control Station can be configured for using IPv6 during the installation process, or later using either Unisphere, or CLI. With the current version of VNX code, the control station supports two types of IP configuration. The configurations supported are; IPv4 only and IPv4/IPv6 at same time. The configuration of IPv6 only is not currently supported. For more information on IPv6, please refer to the three-day IPv6 Workshop provided by EMC. NotE. VNX Installation Assistance cannot be used for configuring IPv6.
