VNX Solutions Expert Exam for Technology Architects v9.0 (E20-880)

Your customer is reporting less than optimal performance for their online payment processing application. The payment processing application is running on a Windows
Server cluster with the back-end Oracle databases running on Oracle Enterprise Linux
(OEL). Both the application and database environments have been presented storage from the customer's VNX solution.
Which tool is best suited to identify database performance issues?

You have designed a VNX for File solution for a creative content provider. The solution involves 10, 2 TiB file systems. Each file system has a Checkpoint taken every hour, refreshed every day. The customer predicted a 2% daily change rate, and SavVol storage was allocated based on that change rate.
Sometime after the implementation, the customer notices that some of the older
Checkpoints are disabled.
What is the most likely explanation?

A customer has implemented a VNX array that hosts multiple SQL database applications, but there are significant performance issues with some of the applications. They have purchased a small number of Flash drives and have asked for your recommendation on maximizing performance using the limited number of new drives.
What suggestion would you make about using the Flash drives?

Which action would be most effective in reducing the performance impact of a Snapshot on a Source LUN?

As a result of suffering a catastrophic failure, your customer has requested a DR solution.
The solution must introduce a higher level of availability for their Exchange 2010 system.
The customer wants a strategy that involves Replication Manager and DAG with third-party replication enabled.
In what state(s) of the database would the replication occur?

A customer has designed an environment using block based LUNs presented to individual hosts. They have configured a pool to start using both thick and thin LUNs. One of the standalone servers is an archive server running on Windows. They want to maximize capacity on the standalone server since the data is no longer accessed. They have no more drives to increase LUN capacity.
How can the customer increase available capacity to the archive server?

You designed the disk layout on a VNX storage system for a large client. They have a very large amount of basic file data consisting of Word documents and text files. The data needs to be accessible but sits for long periods of time without activity.
You decided to place this data on a thin LUN and compress it to maximize capacity. The client is concerned about how much capacity they will reclaim with compression.
Based on the data that is going to be placed on the compressed LUN, what compression ratio will the client typically see?

Replication Manager (RM) is being used to create replicas for a SQL server installed on
VMFS residing on an ESX server. The operations are sent from a separate virtual RM proxy host. However, the RM is not able to successfully create copies.
What is the most likely cause of the failure?

Which tool provides recommendations on how query processing performance can be improved by modifying physical design structures such as indexes, indexed views, and partitioning?

A storage administrator with a VNX Unified solution is using the CLI to monitor the daily storage performance. They must type long commands to examine the statistical types and names to get the desired results. You have been asked to accelerate and ease the monitoring tasks.
What is the most suitable solution?

An Oracle database is stored on an EMC VNX storage array and replicated to a second
VNX array at a DR location. EMC RecoverPoint is providing the replication.
According to best practices, how many Consistency Groups are required to provide application consistent recovery?

You are conducting an analysis of a Celerra system to migrate the data to a new VNX
Unified storage system. You want to measure the current connections for the CIFS/NFS protocol.
Which server_stats statistic type would you use to get the desired information?

Your customer has a VNX array with FAST Cache licensed and two storage pools created.
Only Storage Pool A has FAST Cache enabled.
They currently use both Storage Pools for their general production environment, but would like you to design an environment that will support their Exchange 2010 deployment. There is sufficient free space in both Storage Pools to accommodate their Exchange storage requirements.
Based on EMC best practice guidelines, which design would you recommend?

A customer has recently implemented Microsoft Exchange 2010 on a VNX storage system that hosts a variety of application servers. The Exchange implementation is currently using
RAID 5 (4+1) and uses FAST Cache for the database volumes, but is not using FAST VP.
Performance has been significantly diminished.
What would you recommend to the customer?

A customer is using a virtualized environment with a large number of NFS datastores presented from a VNX system. They are experiencing more than expected network traffic on their datastore networks.
According to EMC best practices, what recommendation should you make to your customer?
