NEW QUESTION # 14
A storage administrator migrated an AIX host using NDM.
When they commit the migration, how is host access to the source array removed?
- A. Masking view is deleted
- B. Source volumes are set NR
- C. Old host paths are set NR
- D. Source volumes are deleted
Answer: A
Explanation:
During a Non-Disruptive Migration (NDM), when the migration is committed, the host access to the source array is removed by deleting the masking view. The masking view is a logical grouping of host initiators, storage ports, and a storage group (which contains volumes). Deleting the masking view removes the host's access to the volumes on the source array12. Reference: Dell EMC PowerMax and VMAX: Non-Disruptive Migration Best Practices and Operational Guide, VMAX/PowerMax Non-Disruptive Migration (NDM) for the IBMi host platform | Dell US Support Knowledge Base Article
NEW QUESTION # 15
NDM is being used to migrate some Windows hosts to a new PowerMax. The client doesn't want the migration target volumes to retain the source volume external device identity following the migration.
What should be used to complete the migration and address the client's concern?
- A. NDM cancel revert function
- B. NDM metro-based mode
- C. NDM Updates feature
- D. NDM pass-through mode
Answer: C
Explanation:
The NDM Updates feature should be used to complete the migration and address the client's concern. The NDM Updates feature is designed to help automate the process of moving applications across arrays requiring a short application downtime. It allows application migration from a VMAX (5876) array to a VMAX3 (5977), VMAX All Flash (5978), or PowerMax (5978) array1. It supports pre-sync data between arrays and then schedule downtime to do the cutover1. Reference: Dell EMC PowerMax and VMAX: Non-Disruptive Migration Best Practices and Operational Guide
NEW QUESTION # 16
During a Non-Disruptive Migration (NDM), what is the result of issuing the ReadyTgt SYMCLI command to the migrating Storage Group?
- A. Confirms that both the source and target arrays can support IDM operations
- B. Source Masking View is removed so the original source paths are in a dead state
- C. Masking View is created on the target array using elements that are created during the create command
- D. Completes the migration by removing the migrated application resources from the source array
Answer: D
Explanation:
During a Non-Disruptive Migration (NDM), issuing the ReadyTgt SYMCLI command to the migrating Storage Group completes the migration by removing the migrated application resources from the source array2. This command is typically issued after all data has been synchronized from the source to the target array and application I/O has been switched to the target array2.

What should be done first to recover from this Concurrent SRDF/Star configuration failure?
- A. Reset the 1st Target Site
- B. Disable Star
- C. Reset the 2nd Target Site
- D. Switch to the 1st Target Site
Answer: D
Explanation:
In a Concurrent SRDF/Star configuration failure, the first step to recover is to switch to the 1st Target Site. This is because in a Concurrent SRDF/Star configuration, there are two target sites and one source site. If there's a failure, the source site can switch to either of the target sites based on the business continuity plan1. Reference: Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide
NEW QUESTION # 18
SRDF/Metro has been deployed and is operating normally. Maintenance tasks at the R1 data center require the array to be offline.
Which SRDF operation should be executed on the Metro RDF pairs to facilitate the planned outage without affecting application I/O?
- A. Split with bias set to R2
- B. Swap
- C. Suspend with bias set to R2
- D. Failover
Answer: B
Explanation:
When maintenance tasks at the R1 data center require the array to be offline, a Swap operation should be executed on the Metro RDF pairs. This operation allows for a planned outage without affecting application I/O by swapping the roles of R1 and R2 devices.

Who has access to run the symaudit -list commands based on the symauth output shown in the exhibit?
- A. Jackie, Jenn. and Ji
- B. Bob and Frank only
- C. Beth only
- D. Beth, Bob, and Frank
Answer: C
Explanation:
The symaudit -list command is used to display audit records for SYMCLI commands. The exhibit shows the output of the symauth -list command, which displays the user groups and access types defined for SYMCLI commands. The output shows that there are two user groups: AdminGrp and EmcMgmtGrp. The AdminGrp group has ADMINRD access type, which means that users in this group can run any SYMCLI command with read-only access. The EmcMgmtGrp group has BASECONTROL access type, which means that users in this group can run only a subset of SYMCLI commands with read/write access. However, the output also shows that there are two exceptions for specific users: Beth and Frank. Beth has ADMINRD access type for all commands, which overrides her membership in EmcMgmtGrp group. Frank has BASECONTROL access type for all commands, which overrides his membership in AdminGrp group. Therefore, the only user who has access to run the symaudit -list command based on the symauth output shown in the exhibit is Beth, since she has ADMINRD access type for all commands2
NEW QUESTION # 20
An administrator has added custom SSL certificates. Each time a client connection is made, default certificates are used.
Which step must be completed?
- A. restart storsrvd
- B. manage server cert update
- C. security_cert_allow wildcards
- D. svmcfq discover
Answer: A
Explanation:
If an administrator has added custom SSL certificates and each time a client connection is made, default certificates are used, then 'restart storsrvd' must be completed. This is because changes to SSL certificates often require a restart of the service that uses them in order for the new certificates to be correctly loaded and used for future client connections1.

- B. 1st level - informational, 9 ms 2nd level - Warning, 14 ms
- C. 1st level - Warning, 10 ms 2nd level - Critical, 15 ms
- D. 1st level - Informational, 10 ms. 2nd level - Warning, 15 ms
Answer: C
Explanation:
The alert settings required are a first level warning at 10 ms and a second level critical alert at 15 ms. These settings will ensure that high I/O response times for a specific storage group are tracked and appropriate actions are taken when the response times exceed the specified thresholds.

NEW QUESTION # 22
A user can create, manage, and delete PowerMax SRDF device pairs. They can also view the array information, masking objects, device information, and the defined RBAC rules. However, they are unable to create and delete SRDF groups.
Which RBAC profile has been assigned to the user's profile?
- A. SecuritvAdmin only
- B. Auditor and
- C. RemoteRep Only
- D. LocalRep and Monitor
Answer: C
Explanation:
The user has been assigned the RemoteRep role only. The RemoteRep role allows users to create, manage, and delete SRDF device pairs, as well as view array information, masking objects, device information, and RBAC rules2. However, it does not allow users to create and delete SRDF groups, which requires the StorageAdmin role. Therefore, answer C is correct.
A, B, and D are incorrect because they do not match the user's profile. SecurityAdmin (A) role allows users to manage security settings such as authentication methods, certificates, RBAC rules, and audit logs2. Auditor (B) role allows users to view array information and audit logs only2. LocalRep (D) role allows users to create, manage, and delete TimeFinder SnapVX sessions from a source device2. None of these roles allow users to create and delete SRDF device pairs.
NEW QUESTION # 23
A company plans to implement SRDF/Star. It is currently using SRDF/S between their two data centers. It is setting up a third data center and wants to have at least two identical copies of its data in case of a primary site failure.
What condition is needed for the connection between the first two sites and the third site?
- A. The link must be able to transport the delta set of the RPO within the company's RTO
- B. Distance cannot exceed 200 kilometers
- C. Latency cannot exceed 40 ms
- D. Any link capable of transporting data with a maximum latency of 15 seconds
Answer: A
Explanation:
A company plans to implement SRDF/Star, which is a three-site replication solution that provides continuous data protection and disaster recovery capabilities. It is currently using SRDF/S between their two data centers, which are located within 200 kilometers and use synchronous replication. It is setting up a third data center and wants to have at least two identical copies of its data in case of a primary site failure. The third site can be located anywhere in the world and use asynchronous replication. The condition that is needed for the connection between the first two sites and the third site is that the link must be able to transport the delta set of the Recovery Point Objective (RPO) within the company's Recovery Time Objective (RTO). The delta set is the amount of data that has changed since the last successful replication cycle. The RPO is the maximum acceptable amount of data loss measured in time. The RTO is the maximum acceptable amount of time to restore normal operations after a disaster. The link must have enough bandwidth and latency to ensure that the delta set can be transferred within the RTO without exceeding the RPO.

NEW QUESTION # 26
An administrator is configuring SYMACL on a PowerMax array.
What are possible ways to get a unique ID for a host system?
- A. Derived from host hardware configuration Randomly generated
- B. Derived from SAN domain ID Derived from local disk configuration
- C. Derived from storage array hardware configuration From a passphrase
- D. Derived from host-based passphrase Randomly generated by Solutions Enabler lockbox file
Answer: D
Explanation:
The SYMACL unique ID for a host system can be obtained in two ways: derived from a host-based passphrase or randomly generated by the Solutions Enabler lockbox file. The host-based passphrase is a string that the user can specify to generate a unique ID for the host. The passphrase can be entered interactively using the symacl -unique -passphrase command, or stored in a file and passed as an argument using the symacl -unique -passphrase -file command. The Solutions Enabler lockbox file is a secure file that stores encryption keys and other sensitive information. The lockbox file can also generate a random unique ID for the host using the symacl -unique command. The lockbox file must be created and initialized before using this method.

NEW QUESTION # 27
Which feature of PowerMax and VMAX All Flash arrays provides ORM functionality?
- A. Write folding
- B. Parallel prefetch
- C. FlashBoost
- D. Write coalescing
Answer: D
Explanation:
The feature of PowerMax and VMAX All Flash arrays that provides ORM functionality is write coalescing. ORM stands for Optimized Resource Management, which is a set of technologies that optimize the performance and efficiency of flash storage. Write coalescing is one of the ORM technologies that reduces the write amplification and extends the life of flash drives. Write coalescing combines multiple small writes into larger sequential writes before destaging them to the flash drives. This reduces the number of write operations and the amount of data that needs to be erased and rewritten on the flash drives, which improves the performance and endurance of the flash storage.

- A. Hosts that are part of AdminGrp proup
- B. Only BASECNTROL access type
- C. Physical hosts that are part of EmcMgmtGrp group
- D. Only ADMINRD access type
Answer: A
Explanation:
The symauth command is used to manage user authorization for SYMCLI commands. The exhibit shows the output of the symauth -list command, which displays the user groups and access types defined for SYMCLI commands. The output shows that there are two user groups: AdminGrp and EmcMgmtGrp. The AdminGrp group has ADMINRD access type, which means that users in this group can run any SYMCLI command with read-only access. The EmcMgmtGrp group has BASECONTROL access type, which means that users in this group can run only a subset of SYMCLI commands with read/write access. Therefore, the correct description of a possible configuration created by SYMACL is hosts that are part of AdminGrp group2
