Recall & Review

beginner

What is the main reason for choosing the right storage in system design?

Choosing the right storage ensures data is stored efficiently, accessed quickly, and scales well with system needs.

beginner

How does storage choice affect system performance?

Storage affects how fast data can be read or written, impacting overall system speed and user experience.

intermediate

Why is scalability important when selecting storage?

Scalability ensures the storage can grow with increasing data without slowing down or failing.

intermediate

What role does data durability play in storage selection?

Durability guarantees data is not lost or corrupted over time, which is critical for reliability.

beginner

How can cost influence the choice of storage?

Cost affects budget and long-term expenses; choosing storage that balances cost and needs is essential.

Which factor is NOT directly affected by the choice of storage?

A User interface design

B System scalability

C Data access speed

D Data durability

User interface design is separate from storage choice and focuses on how users interact with the system.

What does scalability in storage mean?

A Ability to backup data daily

B Ability to store data securely

C Ability to encrypt data

D Ability to grow storage capacity without performance loss

Scalability means the storage can increase capacity smoothly while maintaining performance.

Why is durability important in storage systems?

A To ensure data is never lost or corrupted

B To make data access faster

C To reduce storage cost

D To improve user interface

Durability ensures data remains safe and intact over time.

Which storage type is best for fast read/write operations?

A Cold storage

B Tape backup

C SSD (Solid State Drive)

D Optical discs

SSDs provide fast read/write speeds compared to other storage types.

How does cost influence storage choice?

A It determines the color of storage devices

B It affects budget and long-term maintenance

C It changes the data format

D It controls user permissions

Cost impacts what storage options are affordable and sustainable for the system.
