- A
gcloud compute instances create my-vm --image debian-11 --boot-disk-size 50 --subnet my-subnet
Why wrong: --image is not the correct flag for image family; --boot-disk-size should include GB.
- B
gcloud compute instances create my-vm --image-family debian-11 --image-project debian-cloud --disk-size 50GB --subnet my-subnet
Why wrong: --disk-size is not a valid flag; use --boot-disk-size.
- C
gcloud compute instances create my-vm --image-family debian-11 --image-project debian-cloud --boot-disk-size 50GB --subnet my-subnet
Correct. This uses the appropriate flags and values.
- D
gcloud compute instances create my-vm --image-family debian-11 --boot-disk-size 50 --subnet my-subnet
Why wrong: Missing --image-project and boot-disk-size should be 50GB.

Google ACE Deploying and Implementing a Cloud Solution Practice Question
This ACE practice question tests your understanding of deploying and implementing a cloud solution. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer wants to create a Compute Engine instance with the default Debian 11 image, a 50 GB boot disk, and in a specific subnet. Which command should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"which command"Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.

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
✓
gcloud compute instances create my-vm --image-family debian-11 --image-project debian-cloud --boot-disk-size 50GB --subnet my-subnet
The command 'gcloud compute instances create' with flags --image-family, --image-project, --boot-disk-size, and --subnet correctly creates the instance with the specified configuration.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
gcloud compute instances create my-vm --image debian-11 --boot-disk-size 50 --subnet my-subnet
Why it's wrong here
--image is not the correct flag for image family; --boot-disk-size should include GB.
- ✗
gcloud compute instances create my-vm --image-family debian-11 --image-project debian-cloud --disk-size 50GB --subnet my-subnet
Why it's wrong here
--disk-size is not a valid flag; use --boot-disk-size.
- ✓
gcloud compute instances create my-vm --image-family debian-11 --image-project debian-cloud --boot-disk-size 50GB --subnet my-subnet
Why this is correct
Correct. This uses the appropriate flags and values.
Clue confirmation
The clue word "which command" in the question point toward this answer.
Related concept
CIDR notation defines the prefix length.
- ✗
gcloud compute instances create my-vm --image-family debian-11 --boot-disk-size 50 --subnet my-subnet
Why it's wrong here
Missing --image-project and boot-disk-size should be 50GB.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
Visual reference
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related ACE subnetting questions on CIDR, address ranges, and subnet selection.
