EMC DES-1415 Exam Syllabus Topics:

EMC Specialist - Technology Architect, PowerScale Solutions Sample Questions:

1. A customer has an SMB file directory with 375 TB of data on the primary cluster with a protection level of N+ 3:1. They want to replicate this directory to the secondary cluster. The customer would like information about the possibility of setting protection levels on the target cluster.
What information can be provided to the customer about the protection level for the target directory?
Response:

A) Configured separately on the target cluster and must match the source
B) Controlled by SyncIQ and cannot be altered
C) Controlled by SyncIQ and can be altered by the CLI
D) Configured separately on the target cluster and does not need to match the source

2. What form of journaling redundancy is provided by a PowerScale Gen6 cluster?
Response:

A) In the event of a node failure, the peer journal is written to nonvolatile storage on the paired node.
B) In the event of a node failure, the peer journal is written to disk on the paired node.
C) Each node maintains a copy of the peer journal.The local journal is saved on nonvolatile storage.
D) Each node maintains a copy of the peer journal.The local journal is saved on battery backed-up storage.

3. You are designing a cluster for workloads that have a low latency, heavy, random access pattern. Which node type is designed for this type of workload?
Response:

A) F800
B) A2000
C) A200
D) H5600

4. A customer is inquiring about expanding their primary cluster consisting of six S-Series nodes in order to improve performance. They have a second cluster with 11 X-Series nodes. Both clusters leverage 1GbE, but the customer recently installed a 10GbE network that can be utilized.
They also have multiple Fibre Channel SAN arrays in their environment. They have a variety of workloads on each cluster and are in the process of determining which workloads belong on which cluster.
They have discovered that one of the workloads- a SQL database that resides on the X-Series node cluster - is experiencing timeouts due to latency. The database vendor has suggested limiting latency to 5ms or less to eliminate these timeouts.
How do you advise the customer?
Response:

A) Recommend they increase the amount of DRAM in the cluster or consider an Accelerator node in order to increase the amount of cache in their cluster.
B) Merge the S-Series nodes and X-Series nodes into one cluster, upgrade the 1GbE to 10GbE, and leverage SmartPools to allow for the cluster to determine where data should reside.
C) Consider migrating data from Isilon to one of their SAN platforms or proposing a new solution to handle the performance requirements of SQL.
D) Suggest the customer consider leveraging SSDs in the new nodes they purchase and GNA to boost the performance of each cluster.

5. Which feature will provide data immutability without the ability for the administrator to delete the files under any condition?
Response:

A) Role-based Access Controls
B) Compliance SmartLock
C) Enterprise SmartLock
D) Access Control Entries
