Secure snapshots in PowerFlex are controlled by policies that define their retention and expiration periods. If a snapshot has a lock enabled, it cannot be deleted until the lock is disabled. The lock is a security feature that prevents accidental or unauthorized deletion of the snapshot before its intended retention period1.

To delete a secure snapshot that is still within its expiration period but needs to be removed, the administrator must first disable the snapshot policy lock. Here are the general steps to do so:

• Access PowerFlex Manager.
• Navigate to the Snapshots section.
• Locate the specific snapshot that needs to be deleted.
• Disable the lock on the snapshot policy associated with the snapshot.
• Once the lock is disabled, the snapshot can be deleted manually.

Changing the snapshot expiration period to 30 days (Option C) would not affect the ability to delete the snapshot if the lock is still enabled. The Dual Signature Policy agreement with Dell (Option A) is not a standard procedure for deleting snapshots within PowerFlex and is not related to the administrative controls of snapshot policies.

Therefore, the correct answer is B. Disable the snapshot policy lock on the snapshot, as this action will allow the administrator to delete the snapshot before the expiration period, provided that the snapshot is no longer needed and can be safely removed from the system1.

In PowerFlex File shares, when a soft limit quota is exceeded, it triggers a grace period during which users can still write data to the share. The grace period is a predefined time frame that allows users to either reduce the amount of stored data or to adjust the quota settings. As long as the hard limit quotahas not been reached, users can continue to write files to the share, even if the soft limit has been exceeded and the grace period is in effect1.

The soft limit is essentially a warning threshold that alerts users that they are approaching the maximum allowed capacity, but it does not immediately prevent new writes. The hard limit, on the other hand, is a strict limit that, once reached, will prevent any further writes to the share until the stored data is reduced below the hard limit or the quota is increased.

Since the question states that the number of files is still below the hard limit quota, the user will be able to write a new file to the share location. Therefore, the correct answer is C. The file is written as the hard limit has not been reached.

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.
