EMC E20-885 Online Questions & Answers

• Question 31:

  You are implementing a VNX using AVM, and you cannot create any more dvols from their remaining classic LUNs to create a stripe volume. What could be a reason for this?

  A. LUNs must have the same RAID configuration.
  B. LUNs must come from the same RAID Groups.
  C. LUNs must not exceed 18 TB in size.
  D. LUNs must have different RAID configurations.
  A. LUNs must have the same RAID configuration.

• Question 32:

  You are planning an Exchange 2010 environment. The customer's environment has 500 users. On average, each each user sends 90 and receives 60 messages daily. The average message size is 150 KB with 30 MB of logs per user per day. The Exchange administrator wants to retain five days of transaction logs. What is the minimum total log volume space that should be planned for?

  A. 125 GB
  B. 90 GB
  C. 225 GB
  D. 175 GB
  D. 175 GB

• Question 33:

  A customer wants to implement file system replication between two EMC VNX systems. The source production file system contains data from a sequential workload that resides in a pool composed of NL- SAS drives.

  The destination file system will be configured with a SnapSure schedule for data sharing. Due to cost concerns, the destination file system and SavVol volumes will also be placed on NL-SAS.

  What should you tell the customer about this configuration?

  A. Replicator session performance will decrease because of destination file system checkpoint reads.
  B. NL-SAS is adequate if the source file system is on NL-SAS and contains a random application.
  C. Only Flash and SAS drives should be used for Replicator SavVol volumes.
  D. The destination file system can be used as a source for cascaded replication with no impact to performance.
  A. Replicator session performance will decrease because of destination file system checkpoint reads.

• Question 34:

  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
  C. 10.5 minutes

• Question 35:

  A customer needs to deploy an EMC RecoverPoint/SE cluster.

  What is the minimum required count of RecoverPoint Appliances (RPAs) per cluster?

  A. 1
  B. 2
  C. 4
  D. 8
  B. 2

• Question 36:

  A customer has a RecoverPoint/SE environment with VNX arrays. What would trigger a full sweep of a volume?

  A. Direct Access mode is enabled.
  B. Virtual Access mode is enabled.
  C. The WAN link between clusters becomes degraded.
  D. The assigned primary RPA for a Consistency Group is changed.
  A. Direct Access mode is enabled.

• Question 37:

  An administrator is attempting to vMotion a VM from one vSphere ESXi 5.0 host to another. The ESXi servers are connected to three VNX arrays on the fabric. The vMotion fails. What is the most likely reason?

  A. RDMs are attached to the VM with different host LUN numbers on the ESXi servers.
  B. There are active SnapView sessions on the VM preventing the vMotion.
  C. RDMs are in physical compatibility mode and not eligible for vMotion.
  D. There are active MirrorView sessions on the VM preventing the vMotion.
  A. RDMs are attached to the VM with different host LUN numbers on the ESXi servers.

• Question 38:

  A customer is implementing an Etherchannel environment. They are concerned about how the VNX will handle the traffic load distribution. What is used by EMC VNX to distribute the traffic in an efficient manner?

  A. IP Address
  B. EUI
  C. Round Robin
  D. Serial Number Seed
  A. IP Address

• Question 39:

  Which part of the VNX initiates failover of a Blade?

  A. SP
  B. User
  C. Blade
  D. Control Station
  C. Blade

• Question 40:

  A customer needs to deploy an EMC RecoverPoint/SE cluster with the minimum configuration. How should the IP addresses be configured?

  A. 2 nodes x 2 Ethernet connections + 1 site management
  B. 2 nodes x 1 Ethernet connections + 1 site management
  C. 2 nodes x 2 Ethernet connections + 0 site management
  D. 2 nodes x 1 Ethernet connections + 0 site management
  A. 2 nodes x 2 Ethernet connections + 1 site management
