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.
A company is planning to migrate its on-premises Oracle database to Amazon RDS for Oracle. The database uses Oracle Data Guard for disaster recovery. Which TWO AWS services can be used to assess the database and plan the migration? (Choose TWO.)
AWS Migration Hub
Why wrong: Tracks migration progress, not assessment.
CloudEndure Disaster Recovery
Why wrong: Used for server replication, not database assessment.
AWS Snowball
Why wrong: Used for large data transfers, not assessment.
AWS Database Migration Service (DMS)
DMS can migrate data and assess compatibility.
AWS Schema Conversion Tool (SCT)
SCT assesses and converts database schemas.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Database Migration Service (DMS)
Option C and Option D are correct. AWS DMS can migrate the database, and AWS Schema Conversion Tool (SCT) can assess and convert the schema. Option A is wrong because CloudEndure is for server migration. Option B is wrong because AWS Migration Hub tracks migrations but does not assess databases. Option E is wrong because AWS Snowball is for large data transfer offline.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Migration Hub
Why it's wrong here
Tracks migration progress, not assessment.
CloudEndure Disaster Recovery
Why it's wrong here
Used for server replication, not database assessment.
AWS Snowball
Why it's wrong here
Used for large data transfers, not assessment.
AWS Database Migration Service (DMS)
Why this is correct
DMS can migrate data and assess compatibility.
Related concept
Standard ACLs match source addresses.
AWS Schema Conversion Tool (SCT)
Why this is correct
SCT assesses and converts database schemas.
Related concept
Standard ACLs match source addresses.
Common exam traps
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related DBS-C01 ACL questions on filtering logic and placement.
