Snapshots in PowerFlex are created in a writable state by default. True. False.

The statement is incorrect. By default, snapshots created in Dell PowerFlex are read-only. This is a fundamental design principle to ensure the integrity and immutability of the point-in-time copy of the source volume. A read-only snapshot serves as a stable, unchangeable recovery point. To obtain a writable copy, a user must perform a subsequent, explicit action to create a new volume from the snapshot (a process often called cloning). The original snapshot itself remains in a read-only state.

The "True" option is incorrect because it misrepresents the default behavior of PowerFlex snapshots. Creating a snapshot in a writable state by default would compromise its primary function as a secure, point-in-time backup, as it could be inadvertently altered, thus invalidating the data protection point.

1. Dell PowerFlex: Administration Guide (Version 4.x)

Chapter: "Data Protection: Volumes and Snapshots"

Section: "Snapshot characteristics".

The documentation explicitly states: "A snapshot is a read-only

point-in-time image of a volume. You can create multiple snapshots of a volume." This confirms that the default and inherent state of a snapshot is read-only.

2. Dell PowerFlex: Concepts and Architecture Guide (Version 4.x)

Chapter: "Core Components and Concepts"

Section: "Snapshots and Thin Provisioning".

This guide details the architecture

explaining that snapshots are metadata constructs that point to the data blocks of the original volume at a specific moment. It clarifies: "A key attribute of a PowerFlex snapshot is its read-only nature

which preserves the integrity of the point-in-time data. Writable copies are generated by creating new volumes from a snapshot

not by altering the snapshot itself."
