PAS-C01 Technology Practice Question
Network Topology
An SAP administrator runs the command `aws ec2 describe-volumes --volume-id vol-0abc1234` and sees the following output: ```
{
"Volumes": [
{
"VolumeId": "vol-0abc1234",
"Size": 100,
"VolumeType": "io2",
"Iops": 10000,
"State": "available",
"MultiAttachEnabled": false,
"Attachments": []
}
]
}``` The EC2 instance i-0a1b2c3d4e5f6g7h8 is stopped. What will happen if the administrator attempts to start the instance?
⚠ Common exam trap
Watch out — candidates often assume a stopped instance with a detached volume will fail to start or that the volume type (io2 with 10,000 IOPS) imposes restrictions, when in fact io2 volumes with up to 32,000 IOPS are universally supported and the instance will start normally regardless of the volume's attachment state.
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 instance will start but the volume will not attach because multi-attach is disabled.
The volume is in 'available' state, meaning it is not attached to any instance. Starting a stopped instance does not automatically attach a detached volume; the volume must be manually attached. Therefore, the instance will start successfully but the volume will not be attached, making option C correct.
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 instance will fail to start because the volume type is not supported.
Why it's wrong here
The volume type (io2 with 10,000 IOPS) is supported by all instance types, so this is not a reason for failure.
- ✗
The instance will start successfully and the volume will be attached.
Why it's wrong here
This is incorrect because the volume is not automatically attached when the instance starts; it must be attached separately.
- ✓
The instance will start but the volume will not attach because multi-attach is disabled.
Why this is correct
Correct. The instance will start, but the volume will not be attached because it is currently detached and must be attached explicitly.
- ✗
The instance will start but the volume will be read-only.
Why it's wrong here
There is no indication that the volume would be read-only; volumes are not forced to read-only upon attachment.
