December 14, 2020 by admin EMC E20-562 practice test Welcome to your EMC E20-562 practice test QUESTION 1A service provider has implemented a VPLEX Metro cluster without VPLEX Witness and has implemented a static ruleset. The static ruleset has been set to “cluster-2 detaches”. A Microsoft Windows host in the Cluster-1 data center usesa distributed volume. However, the WAN COM fails.What is the result of this failure?A. 1. VPLEX suspends I/O to all distributed devices on both clusters 2. VPLEX starts a delay timer 3. If connectivity is not restored within the timer expiration period, VPLEX resumes I/O on Cluster-2 and keeps I/O suspended on Cluster-1.B. 1. VPLEX starts a delay timer 2. VPLEX suspends I/O to all distributed devices on both clusters 3. If connectivity is not restored within the timer expiration period, VPLEX resumes I/O on Cluster-1 and keeps I/O suspended on Cluster-2.C. 1. VPLEX suspends I/O to all distributed devices on both clusters 2.VPLEX starts a delay timer 3. If connectivity is not restored within the timer expiration period, VPLEX resumes I/O on Cluster-1 and keeps I/O suspended on Cluster-2.D. 1. VPLEX starts a delay timer 2. VPLEX suspends I/O to all distributed devices on both clusters 3. If connectivity is not restored within the timer expiration period, VPLEX resumes I/O on Cluster-2 and keeps I/O suspended on Cluster-1. QUESTION 2What steps are performed during extent and device migration?A. Start, commit, clean, and removeB. Start, commit, clean, and terminateC. Create, commit, clean, and terminateD. Create, clean, commit and remove QUESTION 3Which command collects the most recent performance statistics from all VPLEX directors?A. SNMPGETBULKB. monitor stat-listC. snmpgetD. monitor collect QUESTION 4What is the relationship between a storage volume and an extent?A. A storage volume can be split into multiple extentsB. An extent must map to an entire storage volumeC. A storage volume can be created out of multiple extentsD. An extent can span multiple storage volumes QUESTION 5In a VPLEX Metro, what factor has a direct impact on VPLEX performance with respect to WAN bandwidth?A. Thin pool rebalancesB. Read rate on distributed volumesC. Raid rebuild on an arrayD. Write rate on distributed volumes QUESTION 6What is a consideration when using VPLEX RecoverPoint enabled consistency groups?A. Repository volume and journal volumes must be indifferent consistency groups.B. Local virtual volumes and distributed virtual volumes can be in the same consistency group.C. Local copy volumes and production volumes must reside in separate consistency groups.D. Production and local copy journals must be indifferent consistency groups. QUESTION 7At which layer of the director IO stack are local and distributed mirroring managed?A. Coherent CacheB. Storage VolumeC. Device VirtualizationD. Storage View QUESTION 8LUNs are being provisioned from an ALUA-capable back-end array to VPLEX. What is the path requirement for each VPLEX director when connecting to this type of array?A. At least two paths to every back-end array and storage volumeB. At least two paths to both the active and passive array controllersC. A least two paths to both the active and non-preferred array controllersD. At least two paths to the active array controller only QUESTION 9What is a supported geometry for a VPLEX device?A. JBODB. RAID-5C. RAID-CD. 2-1 mapping QUESTION 10What happens to global cache size if a director fails and is removed from the cluster?A. SuspendsB. IncreasesC. DecreasesD. Remains as-is QUESTION 11Which protocol does the service laptop use to communicate with and maintain an EMC VPLEX environment?A. SSHB. SNMPC. TelnetD. UDP QUESTION 12What is a valid target for a device data migration in VPLEX?A. Distributed deviceB. Device with no existing virtual volumeC. Device with an existing virtual volumeD. Extent QUESTION 13A storage administrator has created a VPLEX distributed device. The administrator is performing application tests on thehost utilizing the distributed virtual volumes. During testing, some of the write response times appear to be elongated.What is a characteristic of distributed devices that explains this issue?A. Writes need to be written locally to multiple VPLEX Directors before sending a host acknowledgement.B. Writes need to be written to both clusters before sending a host acknowledgement.C. Writes need to be journaled in the VPLEX Witness logging volumes before sending a host acknowledgement.D. Writes need to be protected on the remote disk arrays only before sending a host acknowledgement. Time is Up!
