Exam 1: VPLEX Specialist for Implementation Engineers

When configuring a VPLEX local cluster, according to EMC best practices, how many metadata volumes are required?

What VPLEX user account is required to manage user security?

In a customer's VPLEX Metro environment, a host has been provisioned as a single virtual volume from cluster-1. The customer now needs to convert the local virtual volume to a distributed device. How can the customer accomplish this?

You have attempted to upgrade a VPLEX system to the latest Geosynchrony code. During the upgrade, an error appeared and caused the upgrade to fail. Which file should you review to gather more information about the failure?

Refer to the exhibit. After 6 months of operation, you are monitoring the health of the VPLEX system from the Unisphere Manager for VPLEX. What is the most likely reason for a state change of the VPLEX Witness?

You are preparing to migrate the topology of an installed VPLEX Local system. What is a supported upgrade path?

Refer to the exhibit. You have created a Distributed Device in a VPLEX Metro. You want to confirm you have chosen the correct volumes before performing a mobility job across clusters. You will be moving the device to cluster 1. Which object will be the source for this operation?

What aspect of VPLEX assigns and remembers chunk ownership?

A customer has a VPLEX Metro configuration across two data centers 200 km apart. During an overnight backup, the WAN-COM link between the two data centers fails. What VPLEX object allows for future incremental re-synchronization with the remote mirror once the link is restored?

In which asynchronous Consistency Group Operation stage are the delta sets written to the storage arrays?

Refer to the exhibit. A customer needs to provision storage to a host on Cluster 1, but there is no additional local array capacity to allocate.  How could the customer facilitate assigning storage to the Cluster 1 host from an array locally connected to Cluster 2?

Which protocols are required for a service laptop to communicate with and maintain a VPLEX environment?

Refer to the exhibit. You are preparing to perform an upgrade on an unconfigured VPLEX Metro. When you run the ndu pre-check command, it indicates that it has failed and there are no first upgraders. In your troubleshooting, you run the version -a command. Based on the output, what is the reason for the failure?

A customer has a VPLEX Metro with VPLEX Witness installed and configured. The detach rule for consistency group is "no-automatic-winner". What will VPLEX Witness do in case of a Site 1 failure?

A new VPLEX cluster has been configured. However, you are unable to register any host initiators. After verifying that the host has been properly zoned to the VPLEX cluster, you still cannot register them. What is a possible cause?

What is true about VPLEX CLI?

What is the recommended protection to be used when creating a VPLEX Logging Volume?

Refer to the exhibit. A customer is moving some VMAX devices under a VPLEX Local and is using PowerPath as multipath software. What is the preferred PowerPath load balancing policy assigned to VPLEX volumes?

Which VPLEX management interface is used for initial configuration?

A customer has ordered a new VPLEX, and you are on site doing the initial installation. When creating metadata volumes for the VPLEX Local configuration, the customer asks you how much total storage is needed for the VPLEX metadata. According to EMC best practices, what is the total minimum storage needed for this configuration?
