NEW QUESTION # 11
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. Fast Write
- B. Write Acceleration
- C. Deduplication
- D. SIRT
Answer: A
Explanation:
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.

NEW QUESTION # 12
vWitness and Array Witness options are deployed in the same operating environment simultaneously.
Which option does SRDF/Metro favor in this situation?
- A. Device Bias
- B. Array Witness
- C. Smart DR
- 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 # 13
What is a requirement for the SRDF/Metro devices for an SRDF/Metro personality swap?
- A. Must be RW on the link
- B. Must be in partitioned state
- C. Must be WD on the link
- D. Must be in suspended state
Answer: A
Explanation:
For an SRDF/Metro personality swap, the SRDF/Metro devices must be Read/Write (RW) on the link. This ensures that data can be read from and written to the devices during the swap operation.
NEW QUESTION # 14
A disaster occurred at the workload site of an SRDF/Star configuration. The administrator decides to move the workload to the Synchronous site (Site B).
What symstar command should be used before the workload switch?
- A. disable
- B. cleanup
- C. unpFOlecl
- D. halt
Answer: D
Explanation:
The symstar halt command is used to write disable devices and synchronize SRDF data to remote sites in an SRDF/Star configuration. This command ensures that all sites have a consistent copy of data before switching the workload site from one site to another. Therefore, the symstar halt command should be used before the workload switch in case of a disaster at the workload site of an SRDF/Star configuration1
NEW QUESTION # 15
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 # 16
What environment includes R11 devices?
- A. SRDF/CE
- B. Cascaded SRDF
- C. Concurrent SRDF
- D. SRDF/AR
Answer: B
Explanation:
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.

NEW QUESTION # 17
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 # 19
A host is issuing I/O to a PowerMax.
What happens if the cache space fills up?
- A. I/O will be serviced at the speed of the destination device
- B. I/O will be queued until an empty cache slot is available
- C. Cache is permanently flushed
- 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
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 host-based passphrase Randomly generated by Solutions Enabler lockbox file
- D. Derived from storage array hardware configuration From a passphrase
Answer: C
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 # 22
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. Suspend with bias set to R2
- B. Swap
- C. Split 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.
NEW QUESTION # 23
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. Noisy Neighbor issue
- C. Host queue depth setting was changed
- D. Performance thresholds were exceeded
Answer: B
Explanation:
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.
NEW QUESTION # 24
An application server has the following data characteristics:
80% of the I/O is generated with 8 KB random small blocks
20% of the I/O is generated with 64 KB sequential large blocks
50% of all I/O is a write
What workload profile do these data characteristics represent?
- A. DCS
- B. RWM
- C. OLTP
- D. RRH
Answer: C
Explanation:
The data characteristics represent an Online Transaction Processing (OLTP) workload profile. OLTP workloads typically consist of a high percentage of small, random I/O operations2. In this case, 80% of the I/O is generated with 8 KB random small blocks, which is characteristic of OLTP workloads2.

NEW QUESTION # 25
An administrator implemented SYMACLs on a PowerMax using host-based Access IDs. The administrator is no longer able to run SYMCLI commands against the volumes belonging to a host.
What is a possible reason for this issue?
- A. The disks the volumes were on were replaced
- B. Host network interface card was replaced
- C. SYMAPI options file was manually modified with the wrong host ID.
- D. symacl -unique -passphrase was run using a different passphrase
Answer: C
Explanation:
If an administrator implemented SYMACLs on a PowerMax using host-based Access IDs and is no longer able to run SYMCLI commands against the volumes belonging to a host, one possible reason could be that the SYMAPI options file was manually modified with the wrong host ID. The SYMAPI options file contains configuration settings for Solutions Enabler, including host IDs for access control. If this file is incorrectly modified, it could prevent the administrator from running SYMCLI commands against certain volumes34.

NEW QUESTION # 26
Which feature of PowerMax and VMAX All Flash arrays provides ORM functionality?
- A. FlashBoost
- B. Write coalescing
- C. Write folding
- D. Parallel prefetch
Answer: B
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.

NEW QUESTION # 27
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. SecuritvAdmin only
- C. Auditor and
- 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 # 28
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. Read-only access is available to only the R1 device
- C. Continues to have read/write access to the R1 device
- D. Read-only access is available to both devices
Answer: C
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 # 29
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. QFULL responses of the FA ports
- B. System Write Pending > 75%
- C. I/O sizes over 128 KiB are being used on the hosts
- D. Average disk queue length on the hosts exceed 3
Answer: A
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
