QUESTION NO: 1
A customer currently uses XtremIO native remote replication with four RPAs and a 1 GB
WAN link to asynchronously protect all production data. Management has decided that all data stored on the XtremIO must now be protected at the disaster recovery site by synchronous replication.
How can this be achieved?

A. Purchase four additional RPAs. B. Use a VPLEX splitter C. Set the Link Policy to Synchronous, Dynamic by latency D. Set the Link Policy to Synchronous, Dynamic by throughput

QUESTION NO: 5
A customer has a group of applications that need storage which can provide low response times. The total I/O requirements are 75,000 IOPs with a 4 kB block size. They will have
500 LUNs and need to keep 30 daily snapshots of each LUN.
What is the smallest XtremIO configuration that will meet their needs?

A. 1 cluster with 2 X-Bricks B. 2 clusters with 1 X-Brick each C. 2 clusters with 2 X-Bricks each D. 1 cluster with 4 X-Bricks

Correct Answer: A

QUESTION NO: 6
An XtremIO administrator is having a problem with performance and is troubleshooting the issue. What is an accurate statement about I/O transfers?

A. As I/O size increases, IOPs increase, and latency increases B. As I/O size increases, IOPs decrease, and bandwidth increases C. As I/O size decreases, IOPs decrease, and latency increases D. As I/O size decreases, IOPs increase, and bandwidth increases

QUESTION NO: 7
A customer is considering XtremIO storage for their current Virtual Desktop Infrastructure
(VDI) deployment. The customer wants information on the benefits of an XtremIO solution.
What are the benefits of an XtremIO solution for this environment?

A. Latency is less than 1 ms for small I/O sizes, deduplication and compression, and scales linearly B. Latency is less than 1 ms for small I/O sizes, scales linearly, and slightly higher cost/IOP/GB than hybrid arrays C. Latency is less than 1 ms for large I/O sizes, deduplication and compression, and no reduction in power and cooling costs D. Latency is less than 1 ms for all large I/O sizes, deduplication with compression, and scales linearly
