CompTIA CV0-004 Practice Test 23
Question 220
The infrastructure architect at a regional health provider investigates this condition: an existing relational application needs lower database maintenance overhead while preserving SQL compatibility. Which explanation best accounts for it?
- Rehosting changes the hosting environment with limited redesign, not automatically application modernization.
- Cloud migration must preserve data locality and legal controls across backups, logs and replicas.
- Incremental replication reduces final cutover downtime but the source and target must converge before write ownership moves.
- Replatforming changes supporting platforms without rewriting the complete business application.
Explanation
Correct Answer
D:The evidence of success is: Queries and transactions pass compatibility tests while backup and patch operations shift to the managed service.
Incorrect Answers
A:That approach would help when a legacy billing server cannot be changed before datacenter closure but runs on an OS supported by the target cloud. Check the difference through: Review engine version, extensions, character sets, downtime and replication options.
B:The alternative is aimed at a different condition: A provider-to-provider migration risks moving citizen records into a location prohibited by contract. Replatforming changes supporting platforms without rewriting the complete business application.
C:The proposed measure serves a related cloud task, but the present symptom calls for a more specific response. Replatforming changes supporting platforms without rewriting the complete business application. Check the difference through: Review engine version, extensions, character sets, downtime and replication options.
Question 221
At a global distribution company, an engineer needs to close a case where an existing relational application needs lower database maintenance overhead while preserving SQL compatibility. What test is most decisive?
- Queries and transactions pass compatibility tests while backup and patch operations shift to the managed service.
- Sample data restore and checksums pass before final cutover while schedule fits the deadline.
- The image worker scales independently while order API contracts remain compatible.
- Clients resolve the approved destination and TLS validation remains successful after cutover.
Explanation
Correct Answer
A:Queries and transactions pass compatibility tests while backup and patch operations shift to the managed service. This proves the service behavior rather than just showing a changed configuration. Replatforming changes supporting platforms without rewriting the complete business application.
Incorrect Answers
B:That approach would help when a migration team's internet connection is too slow to transfer several hundred terabytes before the datacenter lease ends. The required acceptance result is: Queries and transactions pass compatibility tests while backup and patch operations shift to the managed service.
C:This proves the service behavior rather than just showing a changed configuration. The relevant cloud response here is: Queries and transactions pass compatibility tests while backup and patch operations shift to the managed service.
D:Clients resolve the approved destination and TLS validation remains successful after cutover. The relevant cloud response here is: Queries and transactions pass compatibility tests while backup and patch operations shift to the managed service.
Question 222
At a regional health provider, this issue is reported: an existing relational application needs lower database maintenance overhead while preserving SQL compatibility. What should be examined before applying a fix?
- Review usage logs, integrations, legal holds and data export requirements.
- Review engine version, extensions, character sets, downtime and replication options.
- Estimate bytes, effective bandwidth, shipment logistics and integrity checks.
- Inspect guest compatibility, disk format, fixed IP dependencies and license terms.
Explanation
Correct Answer
B:Review engine version, extensions, character sets, downtime and replication options. This distinguishes the relevant dependency before changing cloud resources. Replatforming changes supporting platforms without rewriting the complete business application.
Incorrect Answers
A:That approach would help when a legacy dashboard duplicates an already approved analytics service and has no remaining business users. Review engine version, extensions, character sets, downtime and replication options.
C:Estimate bytes, effective bandwidth, shipment logistics and integrity checks. The relevant cloud response here is: Review engine version, extensions, character sets, downtime and replication options.
D:Inspect guest compatibility, disk format, fixed IP dependencies and license terms. The relevant cloud response here is: Review engine version, extensions, character sets, downtime and replication options.
Question 223
At a global distribution company, an operational review finds that an order service cannot scale its image processor without scaling the entire monolith and consuming excessive resources. What is the best next step?
- Retain the existing controlled environment until a compliant alternative is validated.
- Move its database to a compatible managed database service after migration tests.
- Refactor the image workflow into an independently scalable component behind a stable contract.
- Rehost the server with its dependencies mapped and an approved cutover.
Explanation
Correct Answer
C:The change should be verified, not just applied: The image worker scales independently while order API contracts remain compatible.
Incorrect Answers
A:That approach would help when a specialist payroll application uses a hardware key that the proposed cloud platform cannot support before a contractual deadline. In this case, refactoring restructures application internals to improve modularity and scalability rather than merely moving VMs.
B:Replatforming changes supporting platforms without rewriting the complete business application. The relevant cloud response here is: Refactor the image workflow into an independently scalable component behind a stable contract.
D:Rehosting changes the hosting environment with limited redesign, not automatically application modernization. The relevant cloud response here is: Refactor the image workflow into an independently scalable component behind a stable contract.
Question 224
An operator asks why the issue arises: an order service cannot scale its image processor without scaling the entire monolith and consuming excessive resources. Which explanation is strongest?

- Application retirement removes unneeded services while requiring data retention and dependency discovery.
- Refactoring restructures application internals to improve modularity and scalability rather than merely moving VMs.
Explanation
Correct Answer
D:The evidence of success is: The image worker scales independently while order API contracts remain compatible.
Incorrect Answers
A:That approach would help when an existing relational application needs lower database maintenance overhead while preserving SQL compatibility. Check the difference through: Inspect synchronous dependencies, data ownership and contract test coverage.
B:The alternative is aimed at a different condition: Users still reach an obsolete workload after a successful data migration because DNS cache and TLS names were not planned. Check the difference through: Inspect synchronous dependencies, data ownership and contract test coverage.
C:The proposed measure serves a related cloud task, but the present symptom calls for a more specific response. Check the difference through: Inspect synchronous dependencies, data ownership and contract test coverage.
