Cloud Digital Leader Practice Question: Google Cloud products, services, and solutions

This GCDL practice question tests your understanding of google cloud products, services, and solutions. 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

{
  "lifecycle": {
    "rule": [
      {
        "action": {"type": "Delete"},
        "condition": {
          "daysSinceCustomTime": 30
        }
      }
    ]
  }
}

Refer to the exhibit. A company configures a lifecycle policy on a Cloud Storage bucket. The bucket contains objects uploaded over the past year with custom time set on each object. After 60 days, what happens to the objects?

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

✓

Objects with custom time more than 30 days ago are deleted.

Option B is correct because the lifecycle policy uses the `customTime` attribute, and the rule is configured to delete objects when `customTime` is older than 30 days. After 60 days from upload, objects with a `customTime` set at upload will have had that timestamp for 60 days, so they are more than 30 days past their `customTime` and are deleted. The policy does not use object age or last access time.

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.

  • ✗

    All objects older than 30 days from now are deleted.

    Why it's wrong here

    The condition does not use age from upload time; it uses custom time.

  • ✓

    Objects with custom time more than 30 days ago are deleted.

    Why this is correct

    The condition uses daysSinceCustomTime, so objects are deleted when the time since custom time exceeds 30 days.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Objects are deleted after 30 days from the last access.

    Why it's wrong here

    The condition does not consider access time; it's based on custom time.

  • ✗

    The lifecycle policy is invalid because custom time is not supported.

    Why it's wrong here

    Custom time is a valid condition for lifecycle rules.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Google Cloud often tests the distinction between object age (creation time) and custom time, trapping candidates who assume lifecycle policies always use the object's creation date instead of the user-defined `customTime` attribute.

Detailed technical explanation

How to think about this question

The `customTime` metadata field in Google Cloud Storage allows you to set an arbitrary timestamp on each object, independent of its creation time. Lifecycle policies can then use `customTime` in conditions like `daysSinceCustomTime` to trigger actions such as deletion or transition to another storage class. This is useful for scenarios where the deletion schedule must be based on business logic (e.g., data retention after a specific event) rather than the object's upload date. Under the hood, the lifecycle service checks the condition daily and applies the action to objects that meet the threshold.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

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

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
