QUESTION 12
At which point is data compressed when a host sends data to the XtremIO storage system?
A. Inline before data is written to the SSD
B. Once data is written to the storage controller
C. After data is written to the SSDs
D. After data is in SSD cache
Answer: A
Explanation:
XtremIO inline data deduplication and inline data compression services are inline, all the time.

QUESTION 13
A customer has the following requirements for their VDI deployment:
* Greater than 1000 desktops with the ability to grow 10% for the next 3 years
* Low latency boot volumes
* General purpose NAS for home directories
* Remote replication with the ability to snap at every write
* Capable of delivering 100 IOPs per desktop
Which EMC technologies should be recommended?
A. XtremIO, RecoverPoint CRR, and VPLEX only
B. VSPEX Blue, RecoverPoint CDP, and VNX
C. Isilon, VSPEX Blue, VPLEX, and RecoverPoint CDP
D. XtremIO, RecoverPoint CRR, VPLEX, and Isilon
Answer: A
Explanation:
– The EMC RecoverPoint family provides cost-effective, local continuous data protection (CDP), continuous remote replication (CRR), and continuous local and remote replication (CLR) that allows for any-point-in-time data recovery and a new “snap and replicate” mechanism for local and remote replication (XRP).
– Splitter-based replication, using VPLEX.
– RecoverPoint splitter-based replication provides synchronous replication, continuous replication with fine recovery granularity (journal based), and replication for active-active datacenters.
QUESTION 14
You need to design a VDI solution for a customer. Which best practices should be used for VDI environments?
A. Align data on 4 KB boundaries. Put persona and user data on XtremIO LUNs.
B. Align data on 4 KB boundaries. Allocate multiple XtremIO LUNs to each host.
C. Align data on 8 KB boundaries. Put the master VM image on an XtremIO LUN.
D. Align data on 8 KB boundaries. Put all VDI-related data on one large LUN.
Answer: C
QUESTION 15
A customer has a requirement to replicate their VDI to a newly purchased data center located 5 miles away. They require 10-day retention at each site and a continuous replication RPO. However, they want to have the same storage platform at each site. They have a limited budget but need to meet their requirements. Which solution should be recommended to the customer?
A. XtremIO and OpenStack
B. XtremIO with VPLEX and RecoverPoint
C. XtremIO and RecoverPoint
D. XtremIO and MirrorView/A replication
Answer: C
Explanation:
– The EMC RecoverPoint family provides cost-effective, local continuous data protection (CDP), continuous remote replication (CRR), and continuous local and remote replication (CLR) that allows for any-point-in-time data recovery and a new “snap and replicate” mechanism for local and remote replication (XRP).
– Native replication support for XtremIO.
– The native replication support for XtremIO is designed for high-performance and low-latency applications that provides a low Recovery Point Objective of one minute or less and immediate RTO. The benefits include:
* Block level remote or local replication
* Asynchronous local and remote replication
* Policy-based replication to enable optimizing storage and network resources, while obtaining desired
* RPO and RTO
* Application-aware integration
Incorrect:
Not A: OpenStack is the open platform for managing private and public clouds.
Not B: XtremIO with VPLEX and RecoverPoint is a valid solution, but it would be more costly.
