Disks, Partitions, and Filesystems

What is the primary difference between Hard Disk Drives (HDDs) and Solid-State Drives (SSDs)?

• HDDs use flash memory, while SSDs use spinning magnetic platters.

• HDDs are typically faster than SSDs.

• SSDs use flash memory, while HDDs use spinning magnetic platters.

• SSDs are usually less expensive per gigabyte than HDDs.

Which of the following factors is NOT commonly associated with disk performance?

• Rotational speed

• Form factor

• Read/write speeds

• Seek time

What is the primary purpose of an extended partition?

• To act as a primary partition

• To contain logical partitions when more than four partitions are needed

• To improve disk speed

• To format a disk

Which partition table scheme supports disks larger than 2 TB and allows up to 128 partitions?

• MBR

• FAT32

• NFTS

• GPT

Which volume type duplicates data across two or more disks to enhance reliability

• Simple Volume

• Spanned Volume

• Mirrored Volume (RAID 1)

• Striped Volume (RAID 0)

Which filesystem is known for its advanced features such as file permissions, encryption, and journaling?

• FAT32

• APFS

• NTFS

• ext4

Which attribute of a file typically indicates the amount of space it occupies?

• Name

• Permissions

• Size

• Timestamp

What is the main advantage of using the APFS filesystem in macOS and iOS?

• Compatibility with older systems

• Large file and volume support

• Optimized for flash and SSD storage

• Extensive cross-platform compatibility

What does the timestamp attribute of a file track?

• File name changes

• Data encryption status

• File creation, modification, and last access times

• File size variations

What is the primary benefit of using mirrored root disks?

• Increases storage capacity

• Provides data redundancy and improves fault tolerance

• Enhances disk performance

• Reduces the cost of storage
