EMC E20-816 Exam Syllabus Topics:

EMC Symmetrix Solutions Expert Exam for Technology Architects Sample Questions:

1. A company is evaluating SRDF/Star. They are concerned that the RDF daemon represents a single point of failure. How could this concern be addressed?

A) RDF daemons will be deployed on multiple management stations at the workload site. The RDF daemons will cooperate with each other.
B) RDF daemon process runs on the Symmetrix array and has built-in redundancy.
C) RDF daemons will be deployed on one management station at each of the three sites. If the workload site RDF daemon fails, one of the RDF daemons from the other two sites will take over.
D) RDF daemon process runs on the Symmetrix array. If the workload site RDF daemon fails, the RDF daemon from one of the other sites will take over.

2. You are designing a Symmetrix VMAX array with 15K rpm Fibre Channel drives and 7.2K rpm SATA drives. How can you ensure that every back-end director manages just one type of drive?

A) Connect drives of just one type to each engine
B) Load drives of just one type in each disk array enclosure
C) Connect drives of just one type to each front-end director
D) Load drives of just one type in each bay

3. A customer has implemented an Oracle application on a VMAX with a mix of Enterprise Flash Drives (EFD) and FC 15K drives. EFD are configured in RAID 5 and FC 15K both in RAID 5 and RAID 1. In terms of IOPS activity, reads are predominant over writes. The customer decided to place a portion of the database in each tier. Which Oracle database object(s) is suitable to be placed on the FC 15K RAID 1 drives?

5. You are designing a new Symmetrix VMAX storage array to replace a client's Symmetrix DMX4.
Performance data is captured and examined for the DMX4. During the discovery phase, the client states that their critical business application has increased response times when establishing SRDF for 20 logical volumes. Examination of the current configuration of the logical volumes used for the application reveals the following:
-Ten 4way meta volumes at 200 GB
-
Five 8 way meta volumes at 472 GB
-
Five logical volumes at 59 GB
Performance analysis shows that the device write pending counts for the five logical volumes at 59 GB are higher than other volumes used by the application.
The client expects migration events to require a complete establishment of their DR environment logical volumes. How should all the devices be configured on the target Symmetrix VMAX storage array?

A) Meta volumes, minimum 3 members
B) Virtual provisioned single volumes
C) Virtual meta volumes, minimum 2 members
