Google PCA Manage and provision cloud infrastructure Practice Question
This PCA practice question tests your understanding of manage and provision cloud infrastructure. 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.
Exhibit
NAME ZONE MACHINE_TYPE PREEMPTIBLE INTERNAL_IP EXTERNAL_IP
instance-1 us-central1-a n1-standard-4 true 10.128.0.2 35.184.0.1
instance-2 us-central1-b n1-standard-4 false 10.128.0.3 35.184.0.2
Refer to the exhibit. A developer wants to SSH into instance-1 from their local machine. Which command should they use?
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.
Option D is correct because the `gcloud compute ssh` command requires the `--zone` flag when the zone is not set in the gcloud configuration or when the instance is in a different zone than the default. In this scenario, instance-1 is in zone us-central1-a, so specifying `--zone us-central1-a` ensures the SSH connection targets the correct instance. Without this flag, the command may fail or connect to the wrong instance if the default zone is different.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 ssh instance-2
Why it's wrong here
This targets the wrong instance.
✗
gcloud compute ssh instance-1 --project default
Why it's wrong here
The project does not need to be specified explicitly if it's the current project.
✗
gcloud compute ssh instance-1 --internal-ip
Why it's wrong here
Internal IP cannot be reached from outside the VPC.
This command uses the external IP via SSH keys managed by gcloud.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often overlook the zone requirement and assume the `--project` flag or omitting the zone will work, but the PCA exam tests the precise need for zone specification when the default zone is not set or differs from the instance's zone.
Detailed technical explanation
How to think about this question
The `gcloud compute ssh` command uses the Compute Engine API to retrieve instance metadata and then initiates an SSH session via the instance's external IP (or internal IP if `--internal-ip` is used). The zone flag is critical because instance names are only unique within a zone; without it, gcloud uses the default zone set in the configuration or prompts the user. In real-world scenarios, misconfigured zones are a common cause of SSH failures, especially in multi-zone deployments where instances share the same name across zones.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

What is the correct answer to this question?
The correct answer is: gcloud compute ssh instance-1 --zone us-central1-a — Option D is correct because the `gcloud compute ssh` command requires the `--zone` flag when the zone is not set in the gcloud configuration or when the instance is in a different zone than the default. In this scenario, instance-1 is in zone us-central1-a, so specifying `--zone us-central1-a` ensures the SSH connection targets the correct instance. Without this flag, the command may fail or connect to the wrong instance if the default zone is different.
