E20-885 | A heterogeneous Pool is created as…

Question: 8

A heterogeneous Pool is created as follows:
5 x 200 GB FAST VP optimized Flash drives, configured as 4+1 R5
10 x 600 GB 10K rpm SAS drives, configured as 4+1 R5
16 x 2 TB NL-SAS drives, configured as 6+2 R6
Ten equal-sized thick LUNs are created on the pool at 5 minute intervals. No space is left in the pool. All parameters are left at the default value. Testing is started at 9:00 A.M. on the 10 LUNs using IOmeter. The R/W ratio for the testing is set at 3:1, and 4 kB random I/Os are performed.
What throughput do you expect to see from the LUN that was created second?

A. 480 IOPS
B. 960 IOPS
C. 4,100 IOPS
D. 5,600 IOPS

Answer: A

Question: 7

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

Answer: A

Question: 6

A customer recently added several new applications to an EMC VNX. Some of the new applications are experiencing very long response times. The customer suspects a high TCP retransmission rate is causing the long response times. How could the customer determine the TCP retransmission rate?

A. % retransmissions = (retransmissions / packets sent) * 100
B. % retransmissions = (packets sent/retransmissions) * 100
C. % retransmissions = (retransmissions *packets sent) /100
D. % retransmissions = (retransmissions *packets sent) * 100

Answer: A

Question: 5

A customer plans to replicate the active database copy of an Exchange Server 2010 DAG (Database Availability Group) to their warm DR site using RecoverPoint/CRR. The Exchange server hosts a total of seven databases, and the sites are within eight km of each other. Which guideline must be followed for the solution to function as expected?

A. “Database Reads (Recovery) Average Latency” should be below 50 ms.
B. “Database\Log Record Stalls per second” should be below 10 per second
C. “Database\Log Record Stalls per second” spikes should be below 50 per second
D. “Database Reads (Recovery) Average Latency” spikes should be below 500 ms.

Answer: B

Question: 4

A customer is implementing ESXi 5.0 into their heterogeneous environment. Due to separation of duties, the networking and virtualization team must work together to minimize the risk of downtime due to misconfiguration. What ESXi feature can be implemented into the existing switch infrastructure to ease management and avoid configuration issues?

A. Cisco Discovery Protocol
B. NetFlow
C. Juniper Neighbor Discovery Protocol
D. Link Layer Discovery Protocol

Answer: D

Question: 3

You are managing protection using Unisphere for Recover Point. What is the result of disabling a Consistency Group?

A. Copy journal will be cleared.
B. Production journal will be cleared.
C. Group will be deleted.
D. Primary RPA will need to be re-assigned.

Answer: A

E20-885 | A customer creates an incremental SAN Copy…

Question: 2

A customer creates an incremental SAN Copy (ISC) session for a 200 GB LUN on an EMC VNX. The session fails to start, and the customer notes the RLP (reserved LUN pool) contains 300 MB of storage. What action must be taken to get the session started?

A. Increase the RLP storage to 30 GB.
B. Deactivate the ISC snapshot.
C. Enable the SnapView license.
D. Restart the COFW service.

Answer: A

E20-885 | At the local site, application LUNs to be mirrored…

Question: 1

A customer has two VNX systems:

  • At the local site, a VNX capable of performing 10,000 LUN IOPS
  • At the remote site, a VNX capable of performing 7,000 LUN IOPS

At the local site, application LUNs to be mirrored to the remote site perform 2,000 random 4kB IOPS, with a R/W ratio of 4:1. At the remote site, application LUNs to be mirrored to the local site perform 1,200 random 8 kB IOPS, with a R/W ratio of 3:1. The utilization of both systems must be 70% or lower. MirrorView/A will be used to replicate the data. How much throughput can be performed by other applications at the local and remote sites?

A. Local: 3,200 IOPS; Remote: 1,300 IOPS
B. Local: 4,600 IOPS; Remote: 3,100 IOPS
C. Local: 5,600 IOPS; Remote: 4,100 IOPS
D. Local: 6,800 IOPS; Remote: 4,600 IOPS

Answer: A
