A. Flash drives: 960 GB free SAS drives: 2,400 GB free NL-SAS drives: 11,040 GB free

B. Flash drives: 400 GB free SAS drives: 2,500 GB free NL-SAS drives: 11,500 GB free

C. Flash drives: 900 GB free SAS drives: 2,000 GB free NL-SAS drives: 11,500 GB free

D. Flash drives: 970 GB free SAS drives: 2,350 GB free NL-SAS drives: 11,080GB free

A corporation has configured highly available CIFS file systems with VDMs. Replication is configured from a primary site to a secondary site. During testing, the VDM and user file systems switchover successfully, but 30 minutes later Windows clients still cannot access their shares. What is the most likely cause of this problem?

A. VDMs are not configured on the secondary site.

B. The CIFS service is not running on the secondary site.

C. Source side file systems are not correctly sized.

D. Source side VDM Replication licensing is not enabled.

An Oracle DBA creates a new database and requests a LUN to store the online redo logs. What is the recommended configuration for this LUN?

A. RAID 1/0 using SAS drives

B. RAID 5 using Flash drives

C. RAID 1/0 using Flash drives

D. RAID 5 using SAS drives

A customer is running Exchange 2010 on an EMC VNX. The customer recovery SLA mandates they cannot lose more than 10 MB of mail data, and the mail system cannot be down for more than five minutes. What should you implement to meet these recovery objectives without impacting Exchange performance or the recovery SLA?

A. Use a DAG with three database copies

B. Use Replication Manager with Clones

C. Use Replication Manager with snapshots

D. Use log shipping with MirrorView/A

A customer is migrating an Oracle database to a new EMC VNX. The database consists of random, small I/O workloads with high transaction rates.

What RAID type should be used for the LUN containing the data files in order to prevent I/O bottlenecks during peak load?

A. RAID 6

B. RAID 3

C. RAID 1/0

D. RAID 5

You are installing a new VNX and need to implement a Storage Pool on the array. Disks are available and must be set up as follows: 10, 400 GB SSD in R10 (4+4) for the Extreme Performance tier 13, 600 GB + 15K SAS R10 (4+4) for the Performance tier 12, 4 TB NL-SAS R6 (14+2) for the Capacity tier

Disks for FAST Cache, Vault, and unbound disks for sparing, are allocated separately.

How should you lay out the private RAID groups?

A. Extreme Performance tier: 1 R10 (4+4) +1 R10 (1+1) Performance tier: 2 R5 (4+1) + 1 R5 (2+1) Capacity tier: 1 R6 (10+2)

B. Extreme Performance tier: 1 R10 (5+5) + 2 unbound Performance tier: 2 R5 (4+1) + 1 R5 (2+1) Capacity tier: 1 R6 (10+2)

C. Extreme Performance tier: 1 R10 (4+4) + 1 R10 (1+1) Performance tier: 2 R5 (4+1) + 1 R5 (2+1) Capacity tier: 1 R6 (4+2) + 1 R6 (4+2)

D. Extreme Performance tier: 1 R10 (4+4) + 2 unbound Performance tier: 2 R5 (4+1) + 1 R5 (2+1) Capacity tier: 1 R6 (4+2) + 1 R6 (4+2)

A customer has two sites, with a VNX system at each site. The local site has four application LUNs of 512 GB each. They are replicated to the remote site with MirrorView/S. The link between the sites has an effective bandwidth of 100 MB/s. The application generates 1,000 random IOPS of 4 kB with a 3:1 R/W ratio on each of the LUNs. The link fails for five minutes.

How much data is copied to the secondary LUNs as part of the resynchronization process?

A. 4.6 GB

B. 18.3 GB

C. 36.6 GB

D. 73.2 GB

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

Which RecoverPoint/SE Consistency Group copy consists of all of the volumes that are the sources of replication of a Consistency Group?

A. Production Copy

B. Local Copy

C. Remote Copy

D. Journal Volume Copy

A customer currently has a RP/SE single cluster system. They want to add an additional VNX array for replication. The business requires replication from the existing VNX to the new one.

How would they best implement this configuration?

A. Purchase an additional RP/SE cluster. Install it using Deployment Manager, and then connect it to the existing cluster.

B. Purchase an additional RP/SE license for the new VNX. Add the VNX to the existing cluster using Deployment Manager.

C. Zone the new VNX FC ports to the existing RPA ports. Create new Consistency Groups using Unisphere for RecoverPoint.

D. Connect the VNX to the existing SAN. Connect the new array to the existing cluster using Deployment Manager.
