You created a synchronous consistency group, which contains two distributed volumes configured with the rule "set cluster-1-detaches".
What is the expected behavior of the virtual volumes in the event of a WAN-COM failure?
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 a power disruption of 20 seconds in a VPLEX environment, the output of the "vault status" command shows no vaulting processes.
Why did this occur?
Refer to the exhibit.
During a short power disruption to cluster 2, director-2-1-A had failed. Power was restored after 5 minutes. In examining the output of the vault status command, you note that cluster-2's status reads "Cluster is not vaulting/unvaulting".
Why did this message appear?
You are configuring a single engine VPLEX Metro to support both local and distributed volumes. The VPLEX will utilize 10Gb WAN-COM modules in a routed configuration.
According to EMC best practices, what is the minimum number of subnets and IPs required?
Refer to the exhibit.
What is the function of the two highlighted VPLEX VS2 modules?
When performing an installation you notice DHCP has set your Management Server subnet mask to 255.255.255.252. Based on EMC best practices, what is the appropriate subnet mask value for Management Server network 128.221.252.0?
A customer wants to collect performance data for specific virtual-volumes and has created the performance monitor.
What step needs to be performed to enable data capture?
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?
After an expansion of a RAID-0 device in VPLEX, the customer notices a slight degradation of performance. What could cause this?
What are the recommended protection and disk type when selecting a VPLEX Logging Volume?
You created a synchronous consistency group, which contains two distributed volumes configured with the rule "set cluster-1-detaches".
What is the expected behavior of the virtual volumes in the event of a WAN-COM failure?
You are preparing to migrate the topology of an installed VPLEX Local system. What is a supported upgrade path?
What is the total number of engines for a small VPLEX Metro configuration?
A customer has a VPLEX Metro installed. They asked you to recommend a method to non-disruptively move Virtual Volumes from a storage array at Cluster 1 to a storage array at Cluster 2. What would you recommend?
Refer to the exhibit.
Which two metavolume candidates should be used to complete the displayed command?
Refer to the exhibit.
You are planning to perform data mobility between VPLEX Clusters using the GUI. What mobility job options do you have?
Refer to the exhibit.
What is the purpose of VPLEX Witness in a Metro environment?
Following EMC best practices, which information is required to register a VPLEX on an ESRS portal?
In addition to HP-UX, RecoverPoint, SUN-VCS, and AIX, which host type option is available when registering a host initiator in VPLEX?
In which asynchronous Consistency Group Operation stage are the delta sets written to the storage arrays?
Which command would you execute to perform basic system checks to ensure that the VPLEX cluster is working properly?
A customer wants to implement VPLEX between two datacenters 200 km apart. The latency between the sites is 15 ms.
Which VPLEX topology is recommended?
During the installation of a small VPLEX Metro, the command ‘configuration continue-system-setup’ is issued. What is accomplished by this command?
What is a group of VPLEX directors that participate in the cache coherence protocol for a virtual volume?
What is the EMC best practice for the optimum number of back-end storage paths per director presented to a LUN?
Refer to the exhibit.
The customer has not followed EMC best practices when cabling their VS2 VPLEX engine. You are asked how to re-cable the engine to adhere to best practices. What is your response?
During the installation of a VPLEX Local, the command ‘configuration system-setup’ is issued. What is accomplished by this command?
What can you use to generate a list of VPLEX fabric initiator and target identifiers?
A customer has asked you to inspect their SAN connectivity before upgrading their Local configuration to a Metro. What will the output of the connectivity validate-be command provide for an analysis of this environment?
What is the EMC best practice for the optimum number of active back-end storage paths per director for each LUN presented to VPLEX?
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?
In a VPLEX Metro/Geo, which vplexcli command can help to troubleshoot directors latency and routing issues to other Cluster directors?
Refer to the Exhibit.
Based on this diagram of a single VPLEX engine, which protocol is represented by "A"?
What is the maximum number of Virtual Volumes that can be created in a VPLEX Version 5 Cluster?
Click on the calculator in the upper left corner. How much distributed storage can be managed by a 20 GB logging volume?
Refer to the exhibit.
The customer deleted ext_2 on a 20 GB LUN in order to make an extent of 10 GB. Why is the customer unable to create a 10 GB extent?
A service provider has implemented a VPLEX Metro cluster without the VPLEX Witness, but has implemented a static rule set. The static rule set has been set to "Cluster-2 detaches". A Windows host in the Cluster-1 data center uses a distributed volume. The inter-cluster link fails. What happens?
A customer has just introduced a new VPLEX cluster into their storage environment with numerous existing storage arrays. They need to present the host's existing data from the VPLEX cluster.
Which method would you use to perform this operation?
