. The RA Utilization chart shows a maximum utilization of 45%. The "Volume Exceptions" table lists five devices. 

What should you recommend? 

A. Change the application layout 

B. Add more remote adapters 

C. Use three engine VMAX arrays 

D. Turn on software compression on the remote adapters

C. E-Lab Advisor 

D. Change Tracker 

Answer:


Q66. - (Topic 1) 

A Symmetrix Customer has an application that runs 24 hours a day, 7 days a week and 365 days a year. They would like to replicate the application data simultaneously to four branch offices on a nightly basis. The branch offices have EMC VNX arrays. 

Which solution would you recommend? 

A. Use TimeFinder/Clone to replicate the production application. Then use Open Replicator cold push to replicate the clones. 

B. Use Open Replicator cold push to replicate the production devices 

C. Use Open Replicator hot push to replicate the production devices. 

D. Use TimeFinder/Snap to replicate the production application. Then use Open Replicator hot push to replicate the VDEVs. 

Answer:


Q67. - (Topic 1) 

A major telecommunications operator is planning to consolidate multiple mid-tier storage arrays to a single Symmetrix VMAX solution. Their existing environment includes IBM AIX servers, HP-UX Servers and Windows 2003 Servers. 

When documenting the existing Server environment, which command can be used on the AIX Servers, to list the software modules installed? 

A. pkginfo 

B. lslpp 

C. swlist 

D. cfgmgr 

Answer:


Q68. - (Topic 1) 

Refer to the exhibit. 

What is a characteristic of the proposed configuration recommended by TierAdvisor? 

A. It will consume 6% less storage than the current configuration 

B. It will have 49% better response time than the current configuration 

C. It will cost 2% less than the current configuration 

D. It is unsuitable for use with FAST because the tier allocations add up to 100% 

Answer:


Q69. - (Topic 1) 

A Symmetrix VMAX hosts four applications. Each application is assigned a named dynamic cache partition. Two of the partitions are static and two are flexible. The write pending limit for each partition is set to 60%. 

What will happen if an application running in a flexible partition reaches the write pending limit set for that partition? 

A. Host write activity to that partition will be throttled 

B. Cache will be borrowed from the other flexible partition 

C. Cache will be borrowed from the default partition 

D. The write pending limit of the partition will be raised until it reaches 80% 

Answer:


Q70. - (Topic 2) 

You are designing an SRDF/S over Fibre Channel solution. Data centers are 50 km apart and 4 Gb/s FC links are in place. 

What is the minimum number of buffer-to-buffer credits required to maximize the utilization of the links? 

A. 25 

B. 50 

C. 100 

D. 300 

Answer:


Q71. - (Topic 2) 

Your customer is using Replication Manager to make local TimeFinder/Clone backups of their Microsoft Exchange 2010 environment. The customer reconfigured the Exchange environment to place the logs on the L:\\ drive and mount the database on L:\\SG1DB1. 

They updated the associated Replication Manager replica job to reflect the change. The customer reports that the mount of the database to the backup server now fails. 

What do you advise the customer? 

A. Nested mount points are not supported with Replication Manager. 

B. A separate application set must be configured for the database. 

C. Additional clone targets need to be added to the storage pool. 

D. The database replica must be part of the same replica job as the logs. 

Answer:


Q72. - (Topic 2) 

The SiRT feature is enabled on the RA in an SRDF/S configuration. When does the host receive the acknowledgement of a write? 

A. When I/O is written to the cache at the R2 site and acknowledgement is received by the R1 site from R2 site 

B. When I/O is written to R2 site cache but not acknowledged yet 

C. When I/O is written at R1 site cache and sent to the R2 site 

D. Immediately after the I/O is written to R1 cache 

Answer:


Q73. - (Topic 2) 

Your customer is adding a new database application. You are asked to design a solution to expand the current SRDF/S implementation on the customer’s two Symmetrix VMAX arrays to account for this growth. As part of the sizing, you notice that the two RA ports are at 85% utilization. 

What should you tell your customer that the solution requires? 

A. At least two more RAs are required 

B. At least one more RA is required 

C. No additional hardware is required 

D. More memory is required 

Answer:


Q74. - (Topic 1)
