LPIC-1 System Architecture Practice Question

A system administrator runs the command `fdisk -l` and sees the following line: Disk /dev/sda: 1000 GB, 1000204886016 bytes, 1953525168 sectors Based on this output, which statement is true?
⚠ Common exam trap
The trap here is that candidates might assume the disk has a specific partition table type (like GPT) or partition count based on common defaults, but the output only provides disk size and geometry, not partition details, leading to overinterpretation of the data.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The disk is 1 TB
The output from `fdisk -l` shows the total disk size as 1000 GB, which is 1 TB. Thus, option C is correct. The output does not provide information about write protection, partition count, or partition table type.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The disk has write protection enabled
Why it's wrong here
The output lists only disk geometry — size, byte count and sector count — so it carries no write-protection status; that flag appears in read-only device attributes such as those shown by blockdev --getro or hdparm. It tempts because fdisk -l does report partition and disk metadata, but never mount or protection state.
- ✗
The disk has 5 partitions
Why it's wrong here
The line reports only disk geometry — size, bytes and sector count — with no partition table entries, so partition count cannot be inferred. It tempts because fdisk -l output normally lists partitions beneath the disk header, and on a disk whose table is present, counting those entries would be the correct approach.
- ✓
The disk is 1 TB
Why this is correct
The kernel reports the disk as 1000204886016 bytes, which is approximately one trillion bytes. Disk manufacturers quote decimal units, so this capacity is marketed and recognised as 1 TB, not 1 TiB, which would be roughly 1.1 trillion bytes.
- ✗
The disk uses GPT partitioning
Why it's wrong here
Nothing in the header line identifies the partition table type; GPT versus MBR requires inspecting the disklabel or partition entries. It tempts because disks above 2 TiB must use GPT, and for a disk exceeding that threshold, inferring GPT from the size alone would be the correct reasoning.
