Oracle Cloud Infrastructure Migration Architect Professional (1Z0-1123-26) - Practice Exam 1

1. A company has four servers that must cut over together. How should the Cloud Migrations project be organized?
2. A database migration has a small downtime budget and ongoing source writes. What should method selection consider?
3. A file-based application is copied while users continue writing. What consistency question must be addressed?
4. A landing zone has central network administrators and application-specific operators. Which authorization design is appropriate?
5. A large migration requires predictable private bandwidth between a data center and OCI. Which service should be evaluated?
6. A migrated database has correct row counts but some reports disagree with the source. What should be validated?
7. A migrated VM boots successfully, but its application cannot contact a licensed external service. What should be investigated?
8. A migration agent cannot access its required source credentials in Vault. What should be checked?
9. A migration inventory lists servers but not their dependencies. What should be discovered before defining migration waves?
10. A migration leaves temporary public firewall rules and source access keys. What should closure include?
11. A migration program needs an auditable acceptance decision. What should be defined during planning?
12. A migration project discovers that several applications share one database. What should wave planning account for?
13. A migration rehearsal exceeds the outage budget. What should the team do before production cutover?
14. A migration requires encrypted credentials and controlled database access. What should be configured?
15. A migration requires outbound access to public package repositories from private target instances. What should be configured?
16. A migration team wants to preserve a legacy VM architecture unchanged. Which assessment is still necessary?
17. A migration tool reports success, but the application cannot authenticate to the target. What should be checked?
18. A migration uses a temporary privileged source account. What should its lifecycle include?
19. A private migration path also has an encryption requirement. What must be validated?
20. A source VM is lightly used during the collection period but has a major monthly peak. How should target sizing be chosen?
21. A source VM relies on a hardcoded network adapter address. What should migration testing verify?
22. A target application passes basic login but fails a critical end-to-end transaction. What should determine the decision?
23. A target database is promoted and starts accepting new writes. What is required before reverting users to the original source?
24. A target image includes source-specific background jobs. What should be verified during migration testing?
25. A target tenancy needs repeatable identity, networking, and security foundations before migration. What should be evaluated?
26. A target VM uses a different shape from the source. What test is important beyond successful startup?
27. A team lowers a DNS TTL immediately at cutover and expects all clients to forget the old value instantly. What is the problem?
28. A team schedules cutover while large source transactions remain open. What should be considered?
29. A test launch shares network connectivity with the active production source. What risk should be controlled?
30. A wave contains one failed asset and several healthy but dependent assets. What should guide the cutover decision?
31. A workload is operational in OCI but costs far more than planned. What should the post-migration review assess?
32. A workload is split between on-premises and OCI during migration and becomes slow. What should be measured?
33. A workload's guest OS or disk configuration may be unsupported by the planned migration path. What should happen first?
34. After cutover, customers report errors only from one integration partner. What should be investigated?
35. An application has a strict one-hour outage window and a ten-hour initial data transfer. Which approach should be evaluated?
36. An online database migration reports a completed initial load but a nonzero change backlog. Is final cutover necessarily ready?
37. An online migration uses a change-capture path. What source workload characteristic is important for sizing it?
38. Before starting a managed database migration, what should a validation job establish?
39. Before the migration window, which network test provides the strongest readiness evidence?
40. Cloud Migrations stores discovered asset representations in inventory. What is their role?
41. Production cutover succeeds. When should the source environment be decommissioned?
42. Replication lag grows faster than it can be reduced during business hours. What should be evaluated?
43. Source 10.10.0.0/16 must remain reachable during migration. Which target network allocation avoids direct overlap?
44. Target instances resolve OCI private names but cannot resolve corporate application names. What should be reviewed?
45. Target monitoring is not ready when the migration window begins. Why is this a readiness concern?
46. The target database rejects an extension or feature used by the source application. What should happen?
47. What does Cloud Migrations replication prepare for supported VM migration workflows?
48. What should a cutover runbook define before the migration window?
49. What should a migration retrospective preserve for future waves?
50. Which TWO source workload types are explicitly supported by Oracle Cloud Migrations' infrastructure migration service? Select TWO.
