NEW QUESTION # 10
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. Auditor and
- B. SecuritvAdmin only
- C. LocalRep and Monitor
- D. RemoteRep Only
Answer: D
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 # 11
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 metro-based mode
- B. NDM cancel revert function
- 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

What should be done first to recover from this Concurrent SRDF/Star configuration failure?
- A. Switch to the 1st Target Site
- B. Reset the 2nd Target Site
- C. Reset the 1st Target Site
- D. Disable Star
Answer: A
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 # 13
A company wants to implement a three-site disaster recovery solution. It is considering a Concurrent SRDF/Star environment where the production data on R11 devices are replicated to two R2 devices in two remote arrays. Site 2 will use SRDF/S links, and Site 3 will use SRDF/A links from Site 1.
What is the correct configuration for recovery links?
- A. SRDF/A links must be configured between Site 1 and Site 2
- B. SRDF/S links must be configured between Site 1 and Site 3
- C. SRDF/S links must be configured between Site 3 and Site 2
- D. SRDF/A links must be configured between Site 3 and Site 2
Answer: C
Explanation:
In a Concurrent SRDF/Star environment where the production data on R11 devices are replicated to two R2 devices in two remote arrays, SRDF/S links must be configured between Site 3 and Site 2. 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.

Which correctly describes a possible configuration created by SYMACL?
- A. Only ADMINRD access type
- B. Only BASECNTROL 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 # 15
Which metrics are recommended to start analyzing the overall efficiency of the array due to cache?
- A. Cache Balance and Array-level % Hit
- B. %Cache WP and % Reads
- C. % Reads and Host MBs Read/sec
- 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 # 16
What is the correct sequence of actions that take place on a Write Miss?
Answer:
Explanation:
1 - Host sends requests to FE director and no cache slots are found
2 - FE finds available slot by polling
3 - FE sends data from host to mirrored cache locations
4 - FE responds to host to acknowledge successful write
5 - BE destages data as a high-priority task to make slots available
6 - BF destages new data to disk at a later time
NEW QUESTION # 17
Which KPIs should be reviewed when analyzing BE performance using the PowerMax array?
- A. %Busy and Balance
- B. IOPS and Utilization
- C. Balance and Reqs/sec
- D. Reqs/sec and IOPS
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.

NEW QUESTION # 18
An administrator has added custom SSL certificates. Each time a client connection is made, default certificates are used.
Which step must be completed?
- A. security_cert_allow wildcards
- B. restart storsrvd
- C. svmcfq discover
- D. manage server cert update
Answer: B
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 # 19
A host is issuing I/O to a PowerMax.
What happens if the cache space fills up?
- A. Cache is permanently flushed
- B. I/O will be queued until an empty cache slot is available
- C. I/O will be serviced at the speed of the destination device
- D. Cache is temporarily disabled
Answer: B
Explanation:
When the cache space fills up, I/O will be queued until an empty cache slot is available. This is because PowerMax operates as a cache-centric architecture, where all data is passed through cache before being stored on disk. Cache is used to buffer incoming and outgoing data, as well as to support various functions such as replication and data reduction. When cache is full, the array cannot accept any more data until some cache slots are freed up by flushing data to disk or invalidating stale data. Therefore, answer B is correct.
A, C, and D are incorrect because they do not describe what happens when cache space fills up. I/O will not be serviced at the speed of the destination device (A), as this would bypass the cache and degrade performance. Cache is not permanently flushed or temporarily disabled (D), as this would result in data loss or corruption.
NEW QUESTION # 20
SRDF/Metro is deployed in a clustered host configuration. The RDF link state is partitioned, and the R1 side has full read/write capability to the application.
What is the state of the R2 device?
- A. Goes Not Ready to the host
- B. Has full read/write capability to the application
- C. Bias is applied
- D. Has only read capability to the application
Answer: B
Explanation:
In a SRDF/Metro deployment in a clustered host configuration, when the RDF link state is partitioned and the R1 side has full read/write capability to the application, the R2 device also has full read/write capability to the application. With SRDF/Metro, both R1 and R2 devices may then appear as a single virtual device across the two SRDF paired arrays for host presentation. With both the R1 and R2 devices being accessible, the host or hosts (in the case of a cluster) can read and write to both R1 and R2 devices with SRDF/Metro ensuring that each copy remains current, consistent, and addressing any write conflicts which may occur between the paired SRDF devices23.

NEW QUESTION # 21
Which two factors define Capacity Management?
- A. Number of FE ports and number of SCM drives
B Number of BE ports and I/O capacity - B. I/O capacity and storage capacity
- C. Storage capacity and number of SCM drives
Answer: B
Explanation:
The two factors that define Capacity Management are I/O capacity and storage capacity. I/O capacity refers to the ability of the system to handle the incoming and outgoing data traffic from the hosts or applications. Storage capacity refers to the amount of disk space available to store the data. Capacity Management is the process of planning, monitoring, and optimizing the use of these resources to ensure optimal performance, availability, and efficiency of the system.

Which external storage can be connected to PowerMax using DX emulation?
- A. Unity
- B. PowerStore
- C. Compellent
- D. Data Domain
Answer: D
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.

The RDF-ECA timer has expired.
What is the state of all the RDF links?
- A. online
- B. split
- C. suspend
- D. failed over
Answer: C
Explanation:
When the RDF-ECA timer expires, all RDF links will be in a 'Suspend' state. This is because the RDF-ECA timer is used to control how long SRDF waits for an acknowledgement from the remote array before it suspends the link. If an acknowledgement is not received within this time, SRDF assumes that there is a problem with the link or remote array and suspends the link to prevent data loss or corruption.
