CompTIA Cloud+ (CV0-004) — Question 117

A cloud engineer needs to choose a storage technology that fulfills the following requirements:

• 99.99% durability
• Resilient to instance failures
• Resilient to instance deletions

Which of the following types of storage is the best option?

Answer options

• A. Ephemeral
• B. Cache
• C. Persistent
• D. Local

Correct answer: C

Explanation

The correct answer is C, as Persistent storage is designed to offer high durability and is capable of retaining data even in the event of instance failures or deletions. In contrast, Ephemeral storage (A) loses data upon instance termination, Cache (B) is meant for temporary data storage, and Local storage (D) is typically not resilient against instance failures or deletions.
