EMC Dell VPLEX Deploy Achievement Sample Questions (Q50-Q55):

NEW QUESTION # 50
Which consistency group configuration option must be set to ensure that a consistency group will continue synchronization without manual intervention once the link is restored after a link outage?

A. rebuild-type = full
B. rebuild-allowed = true
C. rule-set-name = cluster-1-detaches
D. auto-resume = true

Answer: D

Explanation:
To ensure that a consistency group will continue synchronization without manual intervention once the link is restored after a link outage, the configuration option that must be set is auto-resume = true.
* Consistency Group Configuration: A consistency group in Dell VPLEX is a collection of virtual volumes that are managed together to maintain write-order fidelity. This is crucial for applications that require all writes across multiple volumes to be consistent with each other1.
* Link Outage Handling: In the event of a link outage, it is important for the consistency group to be able to automatically resume synchronization once the link is restored. This minimizes the manual intervention required and ensures data integrity is maintained1.
* Auto-resume Option: The auto-resume = true setting is used to configure the consistency group to automatically resume synchronization. This setting is part of the consistency group's attributes and can be configured via the VPLEX CLI or Unisphere for VPLEX1.
* Implementation: To set this option, the administrator would use the VPLEX CLI to navigate to the consistency group settings and modify the auto-resume attribute to true. This ensures that the consistency group will automatically attempt to resume synchronization after a link outage is resolved1.
* Best Practices: It is recommended to enable auto-resume for all consistency groups that require high availability and automatic recovery from link outages. This setting is part of the best practices for VPLEX consistency groups as outlined in the Dell VPLEX Deploy Achievement documents1.
In summary, the auto-resume = true configuration option is essential for ensuring that a VPLEX consistency group will continue synchronization without manual intervention after a link outage, thereby maintaining the high availability and data protection standards set by Dell VPLEX Deploy Achievement guidelines.

NEW QUESTION # 51
A storage administrator wants to create an XML file to keep a record of each director's paths to storage. Which command creates an XML output file that provides this information?

A. connectivity validate-be
B. storage-volume summary
C. cluster summary
D. cluster configdump

Answer: D

NEW QUESTION # 52
LUNs belonging to an ESXi cluster were encapsulated behind VPLEX. What information must be shared with the ESXi administrator so that they can re-discover the datastore and the RDM LUNs?

A. Virtual volume VPD
B. VML ID
C. UUID of back-end LUN
D. WWN:WWPN

Answer: A

Explanation:
When LUNs belonging to an ESXi cluster are encapsulated behind VPLEX, the ESXi administrator needs to be provided with the Virtual Volume Page Data (VPD) of the virtual volumes. The VPD contains metadata about the virtual volumes that allows the ESXi host to properly identify and interact with them.
* Encapsulation Process: During the encapsulation process, the physical LUNs are virtualized and presented as virtual volumes through VPLEX. This process involves the VPLEX claiming the LUNs and presenting them to the ESXi hosts as new devices1.
* Re-discovery of Datastore and RDM LUNs: After encapsulation, the ESXi administrator must perform a rescan of the storage adapters to discover the new virtual volumes. The VPD of the virtual volumes, which includes information such as the device identifiers and characteristics, is crucial for the ESXi host to recognize and mount the datastores and RDM LUNs2.
* Importance of VPD: The VPD is essential because it provides the ESXi host with the necessary information to differentiate between the virtual volumes and other storage devices. Without the VPD, the ESXi host may not be able to properly identify the encapsulated LUNs, leading to issues with datastore accessibility1.
* Best Practices: It is recommended to follow the best practices and required configurations for a vSphere Metro Storage Cluster using EMC VPLEX Storage array as outlined in VMware KB articles and Dell support documents. This ensures a smooth encapsulation process and proper functioning of the ESXi hosts with the VPLEX storage volumes1.
In summary, sharing the Virtual Volume VPD with the ESXi administrator is a critical step in ensuring that the ESXi cluster can successfully re-discover the datastore and the RDM LUNs after they have been encapsulated behind VPLEX.

NEW QUESTION # 53
What are characteristics of a storage view?

A. An initiator can only be in multiple storage view
VPLEX FE port can be in multiple storage views
Each initiator and FE port pair must be in different storage views
B. An initiator can be in multiple storage views
VPLEX FE port can only be in one storage view
Each initiator and FE port pair can only be in one storage view
C. An initiator can be in multiple storage views
VPLEX FE port can be in multiple storage views
Each initiator and FE port pair can only be in one storage view
D. An initiator can only be in one storage view
VPLEX FE port can be in multiple storage views
Each initiator and FE port pair can be in different storage views

Answer: C

Explanation:
A storage view in Dell VPLEX is a construct that defines the visibility and access control of storage resources for hosts connected to the VPLEX system. The characteristics of a storage view are crucial for ensuring proper access and management of storage resources.
* Initiator Access: An initiator, which is typically a host bus adapter (HBA) on a server, can be part of multiple storage views. This allows a single server to access different storage resources that may be segregated for organizational, performance, or security reasons1.
* VPLEX FE Ports: VPLEX Front-End (FE) ports can be included in multiple storage views. This design allows for flexibility in connecting multiple hosts to various storage resources through the same FE port1.
* Initiator and FE Port Pairing: While an initiator can be in multiple storage views and a VPLEX FE port can be part of multiple storage views, each specific initiator and FE port pair can only be in one storage view. This restriction ensures that a unique path is maintained between a host and its storage resources, which is important for managing access and avoiding conflicts1.
* Storage View Configuration: When configuring a storage view, it is essential to correctly map the initiators to the VPLEX FE ports and assign the appropriate virtual volumes. This setup defines which hosts can access which storage volumes through which paths1.
* Best Practices: It is recommended to follow Dell's best practices for VPLEX storage views to ensure optimal performance, security, and manageability. These practices include proper zoning, LUN masking, and storage view management as outlined in Dell VPLEX documentation1.
In summary, the verified characteristics of a storage view in a Dell VPLEX environment are that an initiator can be in multiple storage views, a VPLEX FE port can be in multiple storage views, but each initiator and FE port pair can only be in one storage view. This configuration ensures that storage resources are properly allocated and managed within the VPLEX system.

NEW QUESTION # 54
A company has VPLEX Metro protecting two applications without Cluster Witness:
. App1 distributed virtual volumes are added to CG1, which has detach-rule set cluster-1 as winner
. App2 distributed virtual volumes are added to CG2, which has detach-rule set cluster-2 as winner What should be the consequence if cluster-2 fails for an extended period?

A. I/O for CG1 is detached at cluster -1; I/O is serviced at cluster-2I/O for CG2 is detached at cluster -2; I/O is serviced at cluster-1
B. I/O for CG1 is suspended at cluster -1; I/O is serviced at cluster-2I/O for CG2 is serviced at cluster -2; I/O is suspended at cluster-1
C. I/O for CG1 is serviced at cluster -1; I/O is suspended at cluster-2I/O is serviced for CG2 at cluster -2; I/O is suspended at cluster-1
D. I/O for CG1 is suspended at cluster -1; I/O is serviced at cluster-2I/O for CG2 is serviced at cluster -1; I/O is suspended at cluster-2

Answer: D

Explanation:
In a VPLEX Metro environment without a Cluster Witness, consistency groups (CGs) are used to manage distributed virtual volumes with detach rules that determine the behavior during a cluster failure.
* CG1 with Cluster-1 as Winner: For App1, the distributed virtual volumes are added to CG1, which has a detach rule set with cluster-1 as the winner. This means that if cluster-2 fails, I/O for CG1 will continue to be serviced at cluster-1 after it automatically attaches the volumes that were distributed across both clusters1.
* CG2 with Cluster-2 as Winner: For App2, the distributed virtual volumes are added to CG2, which has a detach rule set with cluster-2 as the winner. In the event of a cluster-2 failure, I/O for CG2 will be serviced after the volumes are detached from cluster-2, allowing cluster-1 to take over and service the I/O1.
* Extended Cluster-2 Failure: If cluster-2 fails for an extended period, the VPLEX Metro will follow the detach rules set for each consistency group. CG1 will have its I/O serviced at cluster-1, and CG2 will also have its I/O serviced at cluster-1 after detaching from the failed cluster-21.
* No Cluster Witness: Without a Cluster Witness, the VPLEX Metro relies on the detach rules defined in the consistency groups to determine how to handle I/O in the event of a cluster failure1.
* Operational Continuity: The goal is to maintain operational continuity for both applications. By servicing I/O for both CG1 and CG2 at cluster-1, VPLEX ensures that both applications remain operational despite the failure of cluster-21.
In summary, if cluster-2 fails for an extended period in a VPLEX Metro setup without a Cluster Witness, I/O for CG1 will be serviced at cluster-1, and I/O for CG2 will also be serviced at cluster-1 after detaching from cluster-2, as per the detach rules set for each consistency group.
