質問 # 18
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 without the -copy option
- B. Set copy pace 16
- C. Relink with the -precopy option
- D. Set copy to URGENT
正解：C
解説：
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.

Who has access to run the symaudit -list commands based on the symauth output shown in the exhibit?
- A. Beth only
- B. Beth, Bob, and Frank
- C. Jackie, Jenn. and Ji
- D. Bob and Frank only
正解：A
解説：
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
質問 # 20
If the host is cross connected in an SRDF/Metro configuration, what happens if the R2 device becomes Not Ready?
- A. Continues to have read/write access to the R1 device
- B. Read-only access is available to only the R1 device
- C. Loses read/write access to both devices
- D. Read-only access is available to both devices
正解：A
解説：
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.

質問 # 21
A PowerMax storage group is no longer SL compliant. No changes to application I/O profile have occurred.
Which factor is most likely responsible for the SL compliance impact?
- A. Queue depth full event
- B. Performance thresholds were exceeded
- C. Host queue depth setting was changed
- D. Noisy Neighbor issue
正解：D
解説：
A noisy neighbor issue occurs when one or more applications consume more resources than expected, causing performance degradation for other applications. This can affect the SL compliance of a storage group, as the service level defines the expected response time and performance for the applications in that group. If a noisy neighbor consumes too much cache, bandwidth, or CPU cycles, it can cause the SL compliance to drop below the target level. Therefore, answer A is correct.
B, C, and D are incorrect because they are not likely to cause SL compliance impact for a storage group. Queue depth full event (B) is a host-side issue that occurs when the host queue depth is too low or the host I/O rate is too high, causing the host to stop sending I/O requests to the array. Host queue depth setting is also a host-side parameter that determines how many I/O requests can be queued by the host. Performance thresholds (D) are user-defined values that trigger alerts when certain metrics exceed or fall below the specified levels. None of these factors affect the SL compliance of a storage group on the array.
質問 # 22
What is the minimum number of samples that must be collected via a single Real Time Trace collection process in Unisphere for PowerMax?
- A. 0
- B. 1
- C. 2
- D. 3
正解：A
解説：
The minimum number of samples that must be collected via a single Real Time Trace collection process in Unisphere for PowerMax is 1040. This is because the Real Time Trace feature allows the user to collect performance data at 30-second intervals for up to 8 hours, which results in 1040 samples (8 x 60 x 60 / 30 = 1040). The Real Time Trace feature can be used to monitor the performance of storage groups, directors, ports, or devices at a granular level and identify any potential issues or bottlenecks.

- A. Swap
- B. Suspend with bias set to R2
- C. Split with bias set to R2
- D. Failover
正解：A
解説：
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.

質問 # 25
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. Array-level % Hit and % Cache WP
- D. % Reads and Host MBs Read/sec
正解：C
解説：
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.

質問 # 26
A company has two PowerMax arrays located 100 km apart. The arrays are configured with SRDF/S over Fibre Channel.
Which Dell EMC technology improves FC replication between sites?
- A. Deduplication
- B. Fast Write
- C. Write Acceleration
- D. SIRT
正解：B
解説：
Fast Write is a Dell EMC technology that improves Fibre Channel (FC) replication between sites in a SRDF/S configuration. When a write I/O is issued by the host to the R1 device, SRDF with Fast Write acknowledges the write to the host as soon as the data is stored in the R1's cache and transmitted to the R2's cache. This results in reduced latency and improved performance for FC replication between sites.

質問 # 27
An administrator has added custom SSL certificates. Each time a client connection is made, default certificates are used.
Which step must be completed?
- A. manage server cert update
- B. svmcfq discover
- C. restart storsrvd
- D. security_cert_allow wildcards
正解：C
解説：
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.
質問 # 28
An SRDF/Metro Smart DR configuration experiences a service interruption.
What criteria will the Fault-Aware Witness give a higher priority to when selecting the winning array?
- A. Presence of a DR leq
- B. Synced SRDF/A leg
- C. Bias
- D. Director status
正解：C
解説：
In an SRDF/Metro Smart DR configuration, the Fault-Aware Witness gives a higher priority to Bias when selecting the winning array. The bias settings for the devices are used to determine the preferred winner in the event of a failure2. The preferred winner is the side that has priority when requesting the lock from the witness instance2. Reference: Dell EMC PowerMax and VMAX All Flash: SRDF/Metro Overview and Best Practices
質問 # 29
vWitness and Array Witness options are deployed in the same operating environment simultaneously.
Which option does SRDF/Metro favor in this situation?
- A. Witness
- B. Device Bias
- C. Array Witness
- D. Smart DR
正解：A
解説：
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.
質問 # 30
During a Non-Disruptive Migration (NDM), what is the result of issuing the ReadyTgt SYMCLI command to the migrating Storage Group?
- A. Source Masking View is removed so the original source paths are in a dead state
- B. Masking View is created on the target array using elements that are created during the create command
- C. Completes the migration by removing the migrated application resources from the source array
- D. Confirms that both the source and target arrays can support IDM operations
正解：C
解説：
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.

質問 # 31
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
正解：C
解説：
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
質問 # 32
Which is correct about Unisphere for PowerMax and Solutions Enabler permission management?
- A. Unisphere can assign a maximum of two roles per user Solutions Enabler can assign up to four roles per user
- B. Unisphere and Solutions Enabler have authorization checking disabled by default
- C. Unisphere and Solutions Enabler permission information is maintained in separate symauth databases.
- D. Unisphere has a more explicit authentication mechanism for users Solutions Enabler uses the operating system user credentials
正解：D
解説：
Unisphere for PowerMax and Solutions Enabler have different ways of managing user permissions. Unisphere has a more explicit authentication mechanism for users, where each user must have a username and password to log in to the Unisphere interface. Unisphere also supports role-based access control (RBAC), where each user can be assigned one or more roles that define their level of access to the storage system resources and operations. Unisphere maintains the user and role information in a symauth database, which can be shared with Solutions Enabler. Solutions Enabler, on the other hand, uses the operating system user credentials to authenticate users. Solutions Enabler does not require users to have a username and password to run commands, but it checks the symauth database to verify if the user has the appropriate role to perform the requested operation. Solutions Enabler also supports RBAC, where each user can be assigned up to four roles that define their level of access to the storage system resources and operations.

質問 # 33
An SRDF/Metro device pair was in an ActiveActive state. A link failure between arrays occurs. The application continues running on the R1 side, and the link failure is addressed.
What is the current state of the Metro device pair?
- A. Partitioned
- B. Active Active
- C. Suspended
- D. Active Bias
正解：D
解説：
An SRDF/Metro device pair was in an ActiveActive state, meaning that both the R1 and R2 devices were read/write accessible to the host or hosts. A link failure between arrays occurs, causing the device pair to become Not Ready (NR) on the SRDF link. SRDF/Metro responds by making the non-biased or R2 paired device inaccessible (not ready) to the host or host cluster, while keeping the biased or R1 paired device accessible (ready). This ensures that there is no data inconsistency or split-brain scenario between the two sites. The device pair enters an Active Bias state, which indicates that only one side of the pair is active and has a bias attribute set. The bias attribute determines which side of the pair remains accessible in case of a link failure. By default, the bias is set to the R1 side of the pair, but it can be changed using the symrdf set bias command. The application continues running on the R1 side, and the link failure is addressed. Once the link is restored, the device pair resumes the ActiveActive state and both devices become accessible again.

質問 # 34
Which external storage can be connected to PowerMax using DX emulation?
- A. Unity
- B. PowerStore
- C. Data Domain
- D. Compellent
正解：C
解説：
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.
質問 # 35
Which KPIs should be reviewed when analyzing BE performance using the PowerMax array?
- A. IOPS and Utilization
- B. Reqs/sec and IOPS
- C. %Busy and Balance
- D. Balance and Reqs/sec
正解：C
解説：
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.

質問 # 36
SRDF/Metro has been implemented with the bias setting. The R1 side of the pair is configured as the bias side.
How does the device bias work with the R2 device if the R1 array has a failure?
- A. Device bias performs a half-swap, and the R2 device becomes the new R1 device
- B. Device bias is unable to make the R2 device available to the host
- C. R2 device automatically becomes the active device
- D. R2 device automatically becomes the bias device
正解：C
解説：
In an SRDF/Metro configuration with bias setting, if there is a failure at the R1 array (which is configured as the bias side), the R2 device automatically becomes the active device. This means that even if there's a failure on the R1 side, operations can continue on the R2 side without interruption, ensuring high availability.

- A. SRDF/CE
- B. SRDF/AR
- C. Concurrent SRDF
- D. Cascaded SRDF
正解：D
解説：
R11 devices are included in a Cascaded SRDF environment. In a cascaded SRDF configuration, the R1 device at the primary site is paired with an R11 device at the secondary site, which is then paired with an R2 device at the tertiary site2.

質問 # 38
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/S links must be configured between Site 3 and Site 2
- B. SRDF/A links must be configured between Site 3 and Site 2
- C. SRDF/A links must be configured between Site 1 and Site 2
- D. SRDF/S links must be configured between Site 1 and Site 3
正解：A
解説：
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.
