PAS-C01 Design of SAP Workloads on AWS Practice Question

Exhibit

Refer to the exhibit.

# /etc/fstab entry for HANA data volume
UUID=abc123 /hana/data xfs defaults,noatime 0 0

An SAP administrator is configuring the /hana/data volume for SAP HANA on an EC2 instance. The exhibit shows the /etc/fstab entry. What is the purpose of the 'noatime' mount option?

⚠ Common exam trap

Many candidates confuse 'noatime' with other mount options like 'ro' (read-only) or 'sw' (swap), or assume it is related to performance tuning for swap or quotas, when in fact it specifically targets access time updates to reduce I/O overhead.

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

✓

To disable updating the access time on files, improving performance.

The 'noatime' mount option disables the update of inode access timestamps (atime) on every file read. For SAP HANA, which performs high-frequency I/O operations on the /hana/data volume, this eliminates unnecessary metadata writes, reducing disk I/O overhead and improving overall filesystem performance.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    To enable swap space on the volume.

    Why it's wrong here

    noatime is not for swap.

  • ✗

    To enable disk quotas.

    Why it's wrong here

    noatime is for access time.

  • ✗

    To mount the volume as read-only.

    Why it's wrong here

    Read-only is 'ro'.

  • ✓

    To disable updating the access time on files, improving performance.

    Why this is correct

    noatime reduces write operations.
