Based on the lsblk output, which of the following is true?

⚠ Common exam trap

Watch out — candidates often confuse partition numbering with partition type, assuming that any partition numbered 5 or higher is automatically a primary partition, when in fact on MBR disks, partitions 5+ are always logical partitions inside an extended partition.

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 partition /dev/sda2 is an extended partition.

In the lsblk output, /dev/sda2 is listed as a partition of type 'Extended' (typically shown as 'Extended' or with a partition type ID of 5 in fdisk). Extended partitions cannot be directly formatted or mounted; they serve as containers for logical partitions (e.g., sda5). The lsblk output would show sda2 with no filesystem or mount point, and sda5 would appear as a child of sda2, confirming sda2 is extended.

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 /dev/sdb has an extended partition.
Why it's wrong here
sdb1 is a single partition, no extended.
✗
The root filesystem is mounted from /dev/sda5.
Why it's wrong here
Root is on LVM volume /dev/mapper/vg-root.
✓
The partition /dev/sda2 is an extended partition.
Why this is correct
Size 1K and no mount point indicate extended partition.
✗
The disk /dev/sda has a primary partition sda5.
Why it's wrong here
sda5 is a logical partition (number >4).
