NEW QUESTION # 30
If the host is cross connected in an SRDF/Metro configuration, what happens if the R2 device becomes Not Ready?
- A. Loses read/write access to both devices
- B. Continues to have read/write access to the R1 device
- C. Read-only access is available to both devices
- D. Read-only access is available to only the R1 device
Answer: B
Explanation:
In an SRDF/Metro configuration, if the host is cross-connected and the R2 device becomes Not Ready, the host continues to have read/write access to the R1 device12. This is because SRDF/Metro is designed to provide high availability and continuous data access. If one device becomes inaccessible, the host can still access the other device12.

NEW QUESTION # 31
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. LocalRep and Monitor
- B. RemoteRep Only
- C. SecuritvAdmin only
- D. Auditor and
Answer: B
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.

Which correctly describes a possible configuration created by SYMACL?
- A. Only BASECNTROL access type
- B. Only ADMINRD access type
- C. Physical hosts that are part of EmcMgmtGrp group
- D. Hosts that are part of AdminGrp proup
Answer: D
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
NEW QUESTION # 33
SRDF/A MSC has been configured between two sites. There are two PowerMax arrays at the source site and two PowerMax arrays at the target site. An SRDF/A MSC trip event has occurred.
What happens if the Receive Delta Set on one of the target arrays is incomplete?
- A. Session is marked as Cleanup required
- B. Transmit Delta set is discarded
- C. Receive Delta Set data is discarded
- D. Session is marked as No Cleanup required
Answer: A
Explanation:
The correct answer is D. When an SRDF/A MSC trip event occurs, the Receive Delta Set on the target arrays is checked for completeness. If the Receive Delta Set is incomplete on any of the target arrays, the session is marked as Cleanup required. This means that the data on the target arrays is not consistent and needs to be cleaned up before resuming SRDF/A replication. The symstar cleanup command can be used to discard the incomplete Receive Delta Set data and resume SRDF/A replication from the last consistent point1
NEW QUESTION # 34
A DG group is part of a snapshot schedule which runs each day at 9 am then linked to a set of targets for a full copy after termination. Additional volumes were added which increased the link to full copy time.
What course of action will prevent the issue?
- A. Relink with the -precopy option
- B. Set copy to URGENT
- C. Relink without the -copy option
- D. Set copy pace 16
Answer: A
Explanation:
The -precopy option in the relink command can be used when you want to start copying data to the target devices immediately after the link operation. This can be useful in situations where additional volumes have been added, increasing the link to full copy time. By using -precopy, you ensure that the data starts copying immediately, preventing potential issues.
NEW QUESTION # 35
An administrator is trying to view the SLO Compliance Report but is unable to find data for an issue that occurred 7 months ago.
What is the maximum retention period?
- A. 6 months
- B. Last month
- C. Last 2 weeks
- D. 3 months
Answer: A
Explanation:
The maximum retention period for the SLO Compliance Report is 6 months. This means that data older than 6 months will not be available in the report

Who has access to run the symaudit -list commands based on the symauth output shown in the exhibit?
- A. Beth only
- B. Jackie, Jenn. and Ji
- C. Beth, Bob, and Frank
- D. Bob and Frank only
Answer: A
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 # 38
vWitness and Array Witness options are deployed in the same operating environment simultaneously.
Which option does SRDF/Metro favor in this situation?
- A. Smart DR
- B. Array Witness
- C. Device Bias
- D. Witness
Answer: D
Explanation:
When vWitness and Array Witness options are deployed in the same operating environment simultaneously, SRDF/Metro favors the Witness option over the Array Witness option. This is because the Witness option provides a higher level of protection against split-brain scenarios and data loss than the Array Witness option. The Witness option uses a third-party server to monitor the health and connectivity of both SRDF/Metro arrays and to arbitrate in case of a failure. The Array Witness option uses a third array to store configuration information and to arbitrate in case of a failure. However, the Array Witness option does not monitor the health and connectivity of both SRDF/Metro arrays, and it requires manual intervention to resume SRDF/Metro replication after a failure.

NEW QUESTION # 40
A storage administrator is investigating non-linear variations in throughput when zoning additional hosts to certain front-end adapters. They notice a certain performance characteristic having 10 identical hosts zoned to the same FA ports. After adding the 11th host, the throughput sometimes drops more than 20%.
What is the most likely cause of this behavior?
- A. System Write Pending > 75%
- B. QFULL responses of the FA ports
- C. Average disk queue length on the hosts exceed 3
- D. I/O sizes over 128 KiB are being used on the hosts
Answer: B
Explanation:
The most likely cause of this behavior is QFULL responses of the FA ports. When additional hosts are zoned to certain front-end adapters, the FA ports may not be able to handle the increased I/O requests, resulting in QFULL responses. This can cause non-linear variations in throughput and sometimes a drop in throughput of more than 20%. Reference: Dell EMC PowerMax: Service Levels for PowerMaxOS
NEW QUESTION # 41
Which metrics are recommended to start analyzing the overall efficiency of the array due to cache?
- A. % Reads and Host MBs Read/sec
- B. Cache Balance and Array-level % Hit
- C. %Cache WP and % Reads
- D. Array-level % Hit and % Cache WP
Answer: D
Explanation:
The metrics that are recommended to start analyzing the overall efficiency of the array due to cache are array-level % Hit and % Cache WP. The array-level % Hit metric shows the percentage of read requests that are satisfied from the cache memory, without accessing the physical disks. A high % Hit value indicates that the cache is effective in reducing the read latency and improving the performance. The % Cache WP metric shows the percentage of cache memory that is occupied by write pending data, which is data that has been written to the cache but not yet destaged to the physical disks. A high % Cache WP value indicates that the cache is under pressure and may not have enough space to accommodate new write requests, which can lead to performance degradation. By monitoring these two metrics, a storage administrator can evaluate the overall efficiency of the array due to cache and identify any potential issues or bottlenecks.

NEW QUESTION # 42
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 Updates feature
- B. NDM cancel revert function
- C. NDM pass-through mode
- D. NDM metro-based mode
Answer: A
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 # 43
An application owner is experiencing performance issues for their application. Unisphere for PowerMax is showing the storage group is compliant with the current Service Level.
How should the performance issue be addressed?
- A. Redistribute the application to other front-end host ports on different directors
- B. Redistribute the application to other front-end host ports on the same directors
- C. Adjust the Service Level to a lower level of service
- D. Adjust the Service Level to a higher level of service
Answer: A
Explanation:
An application owner is experiencing performance issues for their application. Unisphere for PowerMax is showing the storage group is compliant with the current Service Level. This means that the performance issue is not caused by the storage system, but by some other factor in the environment, such as network congestion, host configuration, or application workload. One possible way to address the performance issue is to redistribute the application to other front-end host ports on different directors. This can help balance the workload across multiple paths and avoid potential bottlenecks or contention on a single port or director. Unisphere for PowerMax provides a Performance Plan feature that can analyze the current configuration and suggest optimal port allocation for each storage group based on historical data and best practices.

NEW QUESTION # 44
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. Distance cannot exceed 200 kilometers
- B. The link must be able to transport the delta set of the RPO within the company's RTO
- C. Latency cannot exceed 40 ms
- D. Any link capable of transporting data with a maximum latency of 15 seconds
Answer: B
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 # 45
Which external storage can be connected to PowerMax using DX emulation?
- A. Data Domain
- B. Compellent
- C. Unity
- D. PowerStore
Answer: A
Explanation:
Data Domain is the only external storage that can be connected to PowerMax using DX emulation. DX emulation is a specialized back-end DA emulation that handles SAN attached disks. DX directors are configured on existing PowerMax front-end Fibre Channel ports and are required to be implemented in pairs for high availability. DX emulation is used to support ProtectPoint technology, which integrates primary storage with Data Domain protection storage to accelerate backup and recovery. Therefore, answer A is correct1.
B, C, and D are incorrect because they are not external storage that can be connected to PowerMax using DX emulation. Unity (B), PowerStore , and Compellent (D) are primary storage arrays that do not support ProtectPoint technology or DX emulation.

NEW QUESTION # 48
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. svmcfq discover
- D. security_cert_allow wildcards
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.
NEW QUESTION # 49
Which KPIs should be reviewed when analyzing BE performance using the PowerMax array?
- A. %Busy and Balance
- B. Balance and Reqs/sec
- C. Reqs/sec and IOPS
- D. IOPS and Utilization
Answer: A
Explanation:
he %Busy and Balance KPIs are the most important indicators of the BE performance on a PowerMax array. The %Busy metric shows the percentage of time that a BE director is busy processing I/O requests. A high %Busy value may indicate that the BE director is overloaded and cannot keep up with the demand. The Balance metric shows the difference in %Busy between the two BE directors in a pair. A high Balance value may indicate that the workload is not evenly distributed across the pair, which can lead to performance degradation. By monitoring these two KPIs, a storage administrator can identify and troubleshoot any potential issues with the BE performance.
