The correct IAM policy statement is the one that grants the glue:GetDatabase action on the specific database resource ARN. This is because read-only access to a single AWS Glue Data Catalog database requires only the permission to retrieve that database’s metadata, which is precisely what the glue:GetDatabase action provides. On the AWS Certified Data Engineer Associate DEA-C01 exam, this question tests your understanding of the granularity of Glue IAM actions—a common trap is confusing glue:GetDatabase (for a single database) with glue:GetDatabases (for listing all databases) or using glue:GetTable (which applies to tables, not the database itself). The exam frequently pairs Glue permissions with S3 data access, but remember that reading the catalog metadata is separate from reading the underlying data in S3. A useful memory tip: think of "GetDatabase" as the key for a single database entry, just as you would use "GetItem" for a single item in DynamoDB—singular actions for singular resources.
DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Network Topology
Refer to the exhibit. A data engineer runs the AWS CLI command and gets the output shown. The engineer wants to grant a data analyst read-only access to the 'sales_db' database in AWS Glue Data Catalog using IAM. Which IAM policy statement is required?
Option A is correct because to read a database, the user needs glue:GetDatabase. Option B is wrong because glue:GetDatabases is for listing databases. Option C is wrong because s3:GetObject is for data access. Option D is wrong because glue:GetTable is for tables, not databases.
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.
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
