DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. 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.
The exhibit shows an IAM policy attached to a user. The user needs to create a manual snapshot of an RDS DB instance named 'production-db'. Which action will the user be able to perform?
Create a manual snapshot of 'production-db' with the name 'production-db-snapshot'.
Why wrong: The snapshot name must start with 'mydb-' to match the resource ARN pattern.
B
Create a manual snapshot of 'production-db' with the name 'mydb-production-snapshot'.
The snapshot name starts with 'mydb-', matching the allowed resource pattern.
C
Describe the 'production-db' DB instance.
Why wrong: The user can describe instances, but the question asks which action the user will be able to perform; the answer should be the snapshot creation with the correct name.
D
Delete the 'production-db' DB instance.
Why wrong: The Deny statement explicitly denies rds:DeleteDBInstance.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a manual snapshot of 'production-db' with the name 'mydb-production-snapshot'.
Option C is correct because the policy allows CreateDBSnapshot on resources matching 'mydb-*', but the snapshot name must match that pattern. Option A is wrong because DeleteDBInstance is denied. Option B is wrong because the user can create snapshots matching the pattern. Option D is wrong because the user can describe instances.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Create a manual snapshot of 'production-db' with the name 'production-db-snapshot'.
Why it's wrong here
The snapshot name must start with 'mydb-' to match the resource ARN pattern.
✓
Create a manual snapshot of 'production-db' with the name 'mydb-production-snapshot'.
Why this is correct
The snapshot name starts with 'mydb-', matching the allowed resource pattern.
Related concept
Static NAT maps one inside address to one outside address.
✗
Describe the 'production-db' DB instance.
Why it's wrong here
The user can describe instances, but the question asks which action the user will be able to perform; the answer should be the snapshot creation with the correct name.
✗
Delete the 'production-db' DB instance.
Why it's wrong here
The Deny statement explicitly denies rds:DeleteDBInstance.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DBS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Create a manual snapshot of 'production-db' with the name 'mydb-production-snapshot'. — Option C is correct because the policy allows CreateDBSnapshot on resources matching 'mydb-*', but the snapshot name must match that pattern. Option A is wrong because DeleteDBInstance is denied. Option B is wrong because the user can create snapshots matching the pattern. Option D is wrong because the user can describe instances.
