CSA Storage Solutions & Management 2 — Questions and Answers
Question 1: A customer wants to store large video files and needs the most cost-effective long-term solution. Which storage type is most appropriate?
- Solid-state drive (SSD)
- External hard disk drive (HDD) (Correct answer)
- USB flash drive
- Memory card
Correct answer: External hard disk drive (HDD)
External HDDs offer the highest capacity at the lowest cost per gigabyte, making them ideal for storing large video files long-term.
Question 2: Which RAID level provides disk mirroring with no parity, offering the best read performance and full redundancy?
- RAID 0
- RAID 1 (Correct answer)
- RAID 5
- RAID 6
Correct answer: RAID 1
RAID 1 mirrors data across two drives, providing full redundancy and improved read performance but using 50% of total capacity.
Question 3: A small business asks for a storage solution that allows multiple users to access files simultaneously over a network. What should you recommend?
- USB flash drive
- Internal SSD
- Network-Attached Storage (NAS) (Correct answer)
- Blu-ray disc
Correct answer: Network-Attached Storage (NAS)
NAS devices connect directly to a network, allowing multiple users to access and share files simultaneously.
Question 4: What does the term 'RPM' indicate when comparing traditional hard drives?
- Read per minute data rate
- Rotations per minute of the disk platter (Correct answer)
- Recovery points per minute
- Random partition mapping
Correct answer: Rotations per minute of the disk platter
RPM (rotations per minute) describes how fast the disk platter spins; higher RPM generally means faster data access speeds.
Question 5: A customer needs portable storage that works instantly with any modern laptop without installing drivers. Which is the best recommendation?
- eSATA external drive
- Thunderbolt SSD
- USB 3.0 flash drive (Correct answer)
- FireWire HDD
Correct answer: USB 3.0 flash drive
USB 3.0 flash drives are universally compatible with modern laptops and are plug-and-play with no driver installation required.
Question 6: Which storage technology uses NAND flash memory and has no moving parts, making it more shock-resistant than traditional drives?
- HDD
- Optical disc
- SSD (Correct answer)
- Magnetic tape
Correct answer: SSD
SSDs use NAND flash memory chips with no moving parts, making them significantly more resistant to physical shock and vibration.
Question 7: A customer is asking about 'cloud storage.' Which benefit should you emphasize first?
- Faster local access speeds than any SSD
- Access files from any device with an internet connection (Correct answer)
- No subscription or ongoing cost
- Unlimited storage with no capacity restrictions
Correct answer: Access files from any device with an internet connection
The primary benefit of cloud storage is the ability to access files from any internet-connected device, anywhere in the world.
