Which two aspects must be in place before adding a Fault Set? (Select 2)
- A. Protection Domain
- B. Storage Pools
- C. Acceleration Pool
- D. Resource Group
Answer: A,B
Explanation:
Before adding a Fault Set in PowerFlex, two critical aspects must be in place: a Protection Domain and Storage Pools.
Protection Domain: This is a logical grouping of storage resources that share the same protection policy and fault tolerance settings. It defines the boundaries of failure domains and is essential for ensuring data availability and resilience1.
Storage Pools: These are collections of storage media across multiple nodes within a Protection Domain. Storage Pools provide the physical storage where data is actually placed. They are necessary for the creation of volumes and for the distribution of data across the system1.
Fault Sets are used to group nodes that share a common risk of failure, such as being in the same rack or power circuit. When creating Fault Sets, it's important that they are defined within an existing Protection Domain and utilize the storage resources allocated within Storage Pools. This ensures that data remains available and protected even if a Fault Set fails, as the system can rebuild the data using the remaining Fault Sets and Storage Pools1.
The information provided here is based on the best practices and design principles outlined in Dell PowerFlex documentation, which details the requirements for setting up and configuring various components of the PowerFlex system, including Fault Sets1.

NEW QUESTION # 17
Which PowerFlex component provides the information that application servers require to connect to the cluster's virtualized storage?
- A. SDC
- B. MDM
- C. SDR
- D. SDS
Answer: A
Explanation:
The PowerFlex component that provides the information application servers require to connect to the cluster's virtualized storage is the Storage Data Client (SDC). The SDC is installed on application servers and is responsible for translating standard block I/O requests from the server's operating system into network I/O requests that can be understood and processed by the PowerFlex storage cluster.
Here's a detailed explanation:
SDC Role: The SDC acts as the interface between the application servers and the PowerFlex storage system. It allows servers to access the virtualized storage as if it were local to the server1.
Connection Process: When an application server needs to connect to the PowerFlex cluster, the SDC communicates with the Meta Data Manager (MDM) to understand the layout of the storage and then interacts with the Storage Data Server (SDS) to perform I/O operations1.
Virtualized Storage Access: Through the SDC, application servers can perform read and write operations on the virtualized storage volumes provided by the PowerFlex cluster, ensuring seamless integration with the existing applications and services1.
The SDC is a critical component in the PowerFlex architecture, enabling the connection and communication between application servers and the PowerFlex storage cluster, thus facilitating the use of virtualized storage resources1.
NEW QUESTION # 18
A volume has a snapshot policy assigned and snapshot creation is failing What is the cause of this issue?
- A. The snapshot is the 61st created by the policy
- B. The requested snapshot is 126th in the vTree.
- C. The storage pool has 32 000 volumes plus snapshots and is at its limit
- D. The snapshot name does not match the source volume.
Answer: A
Explanation:
The cause of the snapshot creation failure when a volume has a snapshot policy assigned is likely because the snapshot is the 61st created by the policy. According to Dell PowerFlex documentation, of the 126 user-available snapshots per volume, sixty (60) can be used for policy-based snapshot scheduling1. This means that if the policy attempts to create a snapshot beyond this limit, it will fail.
Here's a step-by-step explanation of the issue:
Snapshot Policy Limit: Each volume in a PowerFlex system can have a maximum of 126 user-available snapshots. For policy-based snapshot scheduling, the limit is 60 snapshots per volume1.
Policy-Based Snapshot Creation: When a snapshot policy is in place, it will automatically attempt to create snapshots based on the defined schedule and retention levels.
Failure Point: If the snapshot policy tries to create a snapshot and it is the 61st snapshot for that volume, the creation will fail because it exceeds the limit set for policy-based snapshots1.
Resolution: To resolve this issue, the administrator would need to adjust the snapshot policy to ensure that it does not exceed the limit of 60 snapshots. This may involve modifying the retention levels or the frequency of snapshot creation.
This explanation is based on the snapshot policy details provided in the Dell PowerFlex documentation, which outlines the restrictions and uses of snapshots within the PowerFlex storage system1.

An administrator is creating a NAS server with a Standalone Windows server. Creation of trie NAS server fails What is the cause of the failure?
- A. The NAS server is using the same VLAN as block storage networks
- B. A Storage Pool lor NAS has not been created
- C. DNS was not defined in the NAS server creation wizard
- D. FSN has not been added to the cluster
Answer: B
Explanation:
The creation of a NAS server requires a dedicated storage pool. If a storage pool specifically for NAS has not been created, the NAS server creation will fail. This is because the NAS server needs to allocate space from a storage pool to store the file system data. Without a designated storage pool, the NAS server cannot be configured properly1.
The other options, while important for the operation and integration of a NAS server, are not directly related to the creation process itself. For instance, using the same VLAN as block storage networks (Option B) may lead to network conflicts, but it would not prevent the creation of the NAS server. Similarly, not defining DNS in the NAS server creation wizard (Option C) could cause resolution issues later on, but it is not a prerequisite for the creation of the NAS server. Lastly, while adding FSN to the cluster (Option D) is a necessary step for enabling file system services, it is not the cause of the NAS server creation failure in this context.
Therefore, the correct answer is A. A Storage Pool for NAS has not been created, as it is a fundamental requirement for the NAS server creation process in a PowerFlex environment.

NEW QUESTION # 27
A customer application generates 2 GB/s writes The outage is under two hours. What capacity must be allowed for the journal?
- A. 240 GB
- B. 10.800 GB
- C. 7,200 GB
- D. 14.400 GB
Answer: B
Explanation:
To calculate the required journal capacity, we need to consider the maximum cumulative writes that might occur during an outage. The calculation is based on the application's write bandwidth and the duration of the supported outage. For an application generating 2 GB/s of writes, using a 2-hour outage (which is 7200 seconds), the journal capacity reservation needed is:
Journal Capacity=Write Bandwidth×Outage Duration
Journal Capacity=2 GB/s×7200 s=14400 GB
However, since the question specifies that the outage is under two hours, we use the minimum outage allowance of 1 hour for the calculation, which is 3600 seconds. Therefore, the correct calculation is:
Journal Capacity=2 GB/s×3600 s=7200 GB
But considering the recommendation to use three hours in the calculations for safety, the needed capacity would be approximately 10.547 TB, which is roughly 10.800 GB12. Hence, the verified answer is 10.800 GB.
