Question 1

An administrator has just created a ScaleIO volume on a VMware ScaleIO 1.31 cluster. To which hosts on the administrator's network can that volume be mapped?

Correct Answer: B

Question 2

Which type of ScaleIO deployment is most similar to a traditional SAN topology?

A. Standalone B. Two layer C. Mixed D. Fully converged

Correct Answer: B

Question 3

A ScaleIO cluster has been implemented with one protection domain, one storage pool, and devices from 44 SDS nodes. Each SDS contributes one, 1 TB disk device to the storage pool. Sparing has been configured whereby up to four SDS nodes can fail without data loss.
What is the total usable capacity that can be provisioned using ScaleIO volumes?

A. 42 TB B. 22 TB C. 20 TB D. 36 TB

Correct Answer: C

Question 4

You have just integrated a ScaleIO cluster with an OpenStack cloud.
While testing the integration, the OpenStack administrator discovers that ScaleIO volume creation from the Horizon UI succeeds.
However, attaching the volume to an OpenStack instance fails.
What is a possible cause?

A. SDC has not been installed in every Nova node B. SDS has not been installed in every Nova node C. OpenStack instance must first be rebooted before the attach operation D. ScaleIO Cinder driver has not been installed in the Cinder node

Correct Answer: A

Question 5

What accurately describes ScaleIO?

A. Packaged hardware and software B. Storage appliance C. Managed service D. Hyper-converged SAN

Correct Answer: D

Question 6

An administrator wants to use the SCLI to determine if ScaleIO read RAM cache is in use in a server. Which command should be used?

A. scli --query_sds B. scli -query_sdc C. scli--query_cache D. scli --query_protection_domain

Correct Answer: A

Question 7

In a fully converged ScaleIO deployment, what applies to every server?

A. Contributes to, and benefits from, ScaleIO storage B. Runs the same operating system as all other servers C. Shares in the creation and maintenance of metadata D. Uses only one tier of storage, even if many ScaleIO pools exist

Correct Answer: A

Question 8

A ScaleIO cluster has been installed with one protection domain, one storage pool, and 10 provisioned volumes. Fault Sets have not been configured. Two SDS servers experience hardware failures and go offline.
What is the maximum severity you would expect for the generated ScaleIO events?

A. WARNING B. CRITICAL C. FATAL D. ERROR
