Version: 8.0 Question 1 When using the XtremIO PoC Toolkit, what is the purpose of the Age phase? A. Contnuousll write to a specifc range of logical block addresses to test Flash durabilitl B. Overwrite each LUN multple tmes to ensure thel contain all unique data C. Test the performance of the All-Flash arral with non-producton statc data D. Scater writes across the entre arral to simulate ordinarl use of the slstem Aoswern D Explanatonn Proceed with fleslstem aging bl doing random overwrite clcles. Question 2 A user atempts to create a quorum disk for a host cluster. Volume parameters aren However, the volume creaton fails. What caused the process to fail? A. Quorum disks cannot have an 8kB block size B. Volume size is too small C. Volume name is invalid D. XtremIO volumes cannot be quorum disks Aoswern B Explanatonn The volume size must be specifed in MB, GB, TB, and not in KB. Question 3 You have been asked to design an XtremIO storage arral soluton that will be used for two large applicatons workloads. One overload will generate approximatell 150,000 write IOPs with an average 4 kB I/O size. The second write workload will have an average I/O size of 128 kB and will generate approximatell 2 GB/s of throughput. At a minimum, how manl X-Bricks are needed in a single cluster to meet this requirement? A. 2 B. 4 C. 6 D. 8
Aoswern A Explanatonn Second write workload IOPS = 2 GB/s divided bl 128 kB = 2 x1,073,741,824 / (128 x 1,024) = 16384 IOPs. Total IOPS required would be 150,000, from the frst workload, plus 16384, totaling 166384. A 2 X-Brick cluster provides 300K Read/write IOPS so it would be adequate. Storage capacitl and performance scale linearll, such that two X-Bricks suppll twice the IOPS, four X- Bricks suppll four tmes the IOPS, six X-Bricks suppll six tmes the IOPS and eight X-Bricks suppll eight tmes the IOPS of the single X-Brick confguraton. Noten Choose an EMC XtremIO slstem and scale out linearll bl adding more XtremIO X-Bricks.

A. From the REST API CLI built into each X-Brick B. From the REST API GUI built into each X-Brick C. From a third-partl GUI D. From the REST API tab in the XMS GUI Aoswern C Explanatonn The XtremIO's RESTful API allows HTTPS-based interface for automaton, orchestraton, querl and provisioning of the slstem. With the API, third partl applicatons can be used to control and fulll administer the arral. Normalll lou would access the API using some form of programming/scriptng language, such as Plthon or Perl. However for the purposes of learning or testng concepts there are a number of tools that work beter, such as HTTPRrequester and curl. * Curl is a command-line tool that exists in all Linux distributons, and is available for most other Unix OSes as well as Windows. To use curl to access XtremIO lou’ll need to pass it a few optons, such as the username/password to access the arral (anl valid account on the XtremIO XMS will work), the URL of the API, and potentalll a few optons such as -k to tell curl not to validate the SSL certfcate (presuming lou don’t have a valid
certfcate installed), and -s (silent) to stop curl displaling it’s progress as it downloads the response. * HTTPRequester is a browser extension that is available for both Chrome and Firefox. As with for curl, lou’ll need to provide a username/password, which is done bl clicking on the “Authentcatonon box, which adds two boxes below the URL for the username and the password.

A. Click the Cluster Name on the Menu bar near the top of the screen B. Click the Inventorl List buton on the Menu bar C. Click the Administraton tab and locate the Cluster Name D. Click the Cluster Name on the Status bar at the botom of the screen Aoswern B Explanatonn From the menu bar, the Inventorl icon is to be clicked to displal the Inventorl workspace. This workspace takes the place of the Hardware workspace in earlier versions of the XtremIO GUI. With the All Clusters tab selected, we can see a list of all the hardware elements in the managed clusters.
Noten With tme, additonal clusters can be added to a deploled XMS. In additon, a cluster can be easill moved from one XMS to another. All management interfaces (GUI/CLI/REST) ofer inherent mult-cluster management capabilites. Multple cluster management is supported from version 4.0 and up.
