CompTIA CV0-004 Practice Test 24
Question 230
Before changing production at a regional health provider, a specialist payroll application uses a hardware key that the proposed cloud platform cannot support before a contractual deadline. Which evidence should the engineer check first?
- Inspect guest compatibility, disk format, fixed IP dependencies and license terms.
- Check vendor support, regulatory requirements and hardware dependency options.
- Monitor replication lag, consistency checks, cutover routing and dual-write risk.
- Review engine version, extensions, character sets, downtime and replication options.
Explanation
Correct Answer
B:Check vendor support, regulatory requirements and hardware dependency options. This distinguishes the relevant dependency before changing cloud resources. Retain decisions are legitimate migration outcomes when technical or regulatory constraints prohibit safe relocation.
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 vendor support, regulatory requirements and hardware dependency options.
C:Monitor replication lag, consistency checks, cutover routing and dual-write risk. The relevant cloud response here is: Check vendor support, regulatory requirements and hardware dependency options.
D:Review engine version, extensions, character sets, downtime and replication options. The relevant cloud response here is: Check vendor support, regulatory requirements and hardware dependency options.
Question 231
The incident responder reviews a case where a legacy dashboard duplicates an already approved analytics service and has no remaining business users. What should the team change first?
- Evaluate an offline bulk-transfer appliance or accelerated private transfer against deadlines.
- Move its database to a compatible managed database service after migration tests.
- Retire the redundant application after preserving required records and dependencies.
- Rehost the server with its dependencies mapped and an approved cutover.
Explanation
Correct Answer
C:Application retirement removes unneeded services while requiring data retention and dependency discovery. The change should be verified, not just applied: Users migrate to the approved service and the old system is decommissioned without lost obligations.
Incorrect Answers
A:That approach would help when a migration team's internet connection is too slow to transfer several hundred terabytes before the datacenter lease ends. In this case, application retirement removes unneeded services while requiring data retention and dependency discovery.
B:Replatforming changes supporting platforms without rewriting the complete business application. The relevant cloud response here is: Retire the redundant application after preserving required records and dependencies.
D:Rehosting changes the hosting environment with limited redesign, not automatically application modernization. The relevant cloud response here is: Retire the redundant application after preserving required records and dependencies.
Question 232
A legacy dashboard duplicates an already approved analytics service and has no remaining business users. What underlying cloud behavior should the engineer recognize?
- Rehosting changes the hosting environment with limited redesign, not automatically application modernization.
- Refactoring restructures application internals to improve modularity and scalability rather than merely moving VMs.
- Incremental replication reduces final cutover downtime but the source and target must converge before write ownership moves.
- Application retirement removes unneeded services while requiring data retention and dependency discovery.
Explanation
Correct Answer
D:The evidence of success is: Users migrate to the approved service and the old system is decommissioned without lost obligations.
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 usage logs, integrations, legal holds and data export requirements.
B:The alternative is aimed at a different condition: An order service cannot scale its image processor without scaling the entire monolith and consuming excessive resources. Application retirement removes unneeded services while requiring data retention and dependency discovery.
C:The proposed measure serves a related cloud task, but the present symptom calls for a more specific response. Application retirement removes unneeded services while requiring data retention and dependency discovery. Check the difference through: Review usage logs, integrations, legal holds and data export requirements.
Question 233
During postchange validation at a global distribution company, a legacy dashboard duplicates an already approved analytics service and has no remaining business users. What outcome would prove the intended safeguard works?
- Users migrate to the approved service and the old system is decommissioned without lost obligations.
- The application remains supported with a dated replacement plan and documented risk acceptance.
- Audit evidence shows sensitive records and their backups remain within approved jurisdictions.
- Checksums and latest transaction positions match and clients successfully write to the new primary.
Explanation
Correct Answer
A:Users migrate to the approved service and the old system is decommissioned without lost obligations. This proves the service behavior rather than just showing a changed configuration. Application retirement removes unneeded services while requiring data retention and dependency discovery.

Question 234
A review identifies this symptom: a legacy dashboard duplicates an already approved analytics service and has no remaining business users. Which read-only investigation is most useful?
- Review engine version, extensions, character sets, downtime and replication options.
- Review usage logs, integrations, legal holds and data export requirements.
- Check vendor support, regulatory requirements and hardware dependency options.
- Inspect synchronous dependencies, data ownership and contract test coverage.
Explanation
Correct Answer
B:Review usage logs, integrations, legal holds and data export requirements. This distinguishes the relevant dependency before changing cloud resources. Application retirement removes unneeded services while requiring data retention and dependency discovery.
Incorrect Answers
A:That approach would help when an existing relational application needs lower database maintenance overhead while preserving SQL compatibility. Review usage logs, integrations, legal holds and data export requirements.
C:Check vendor support, regulatory requirements and hardware dependency options. The relevant cloud response here is: Review usage logs, integrations, legal holds and data export requirements.
D:This distinguishes the relevant dependency before changing cloud resources. The relevant cloud response here is: Review usage logs, integrations, legal holds and data export requirements.
Question 235
At a global distribution company, a large inventory database must migrate with no more than a few seconds of write interruption. Which response most directly addresses this specific cloud challenge?
- Prepare certificate continuity, low-TTL transition and monitored DNS cutover.
- Move its database to a compatible managed database service after migration tests.
- Use supported initial load and change replication followed by controlled write freeze and endpoint switch.
- Select target regions and replication settings that meet residency policy before transfer.
Explanation
Correct Answer
C:Incremental replication reduces final cutover downtime but the source and target must converge before write ownership moves. The change should be verified, not just applied: Checksums and latest transaction positions match and clients successfully write to the new primary.
Incorrect Answers
A:That approach would help when users still reach an obsolete workload after a successful data migration because DNS cache and TLS names were not planned. In this case, incremental replication reduces final cutover downtime but the source and target must converge before write ownership moves.
B:Replatforming changes supporting platforms without rewriting the complete business application. The relevant cloud response here is: Use supported initial load and change replication followed by controlled write freeze and endpoint switch.
D:Cloud migration must preserve data locality and legal controls across backups, logs and replicas. The relevant cloud response here is: Use supported initial load and change replication followed by controlled write freeze and endpoint switch.
