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

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.

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.
