Oracle Cloud Infrastructure Cloud Ops Professional (1Z0-1067-26) - Practice Exam 1

1. A backup is required after a regional outage. What should the operator confirm in advance?
2. A block volume is accidentally deleted. What most directly determines whether its previous contents can be recovered?
3. A compute instance cannot be reached over SSH after an operating-system firewall change. Which recovery approach is most appropriate?
4. A compute launch fails with a capacity error in one availability domain. What is the appropriate response?
5. A configuration depends on a private Git server. Resource Manager cannot reach it. Which capability should be evaluated?
6. A CPU alarm never fires although a graph shows high values for one server. What should be checked?
7. A dashboard shows no metrics for a critical service. What is the safest interpretation?
8. A deployment script contains a tenancy administrator's private key. What is the best remediation for a script running on OCI compute?
9. A fleet needs controlled guest package updates. Which operational design is appropriate?
10. A new subnet has no access to supported regional Oracle services through the intended service gateway. What should be checked?
11. A nightly job fails intermittently while creating resources because the service temporarily rejects requests. What retry design is appropriate?
12. A pipeline upgrades its Terraform provider and proposes unexpected resource replacement. What should happen before approval?
13. A private instance needs outbound internet updates but must not accept unsolicited internet connections. Which gateway is suitable?
14. A private server can reach an IP address but fails when using its hostname. What is the most relevant initial investigation?
15. A production route table changed unexpectedly. Which evidence most directly helps identify the responsible API operation and principal?
16. A public load balancer returns unhealthy for a backend whose process is running. What should be checked?
17. A reboot is scheduled for a customer-managed Linux instance. What should the operator verify first?
18. A scale-out application stores user sessions only in each instance's memory. What operational problem can scale-in cause?
19. A scheduled traffic event is known in advance. Which scaling approach can increase an instance pool before the event?
20. A service's average latency looks normal while some customers experience severe delays. What should be examined?
21. A Site-to-Site VPN tunnel is down. What should the operator examine before changing application code?
22. A team expects a budget alert to terminate resources as soon as the threshold is crossed. What should the operator explain?
23. A team must retain selected objects against ordinary deletion for a specified period. Which control should be evaluated?
24. A team wants to bring existing OCI resources under Terraform management. What should its plan include?
25. A Terraform apply completed some resources before failing. What should the operator do before rerunning it?
26. A user overwrites an important object and needs the earlier contents. Which preconfigured feature most directly supports recovery from this change?
27. A VCN route points to the correct next hop, but TCP connections still fail. Which TWO checks are required? Select TWO.
28. A VM's application reports memory exhaustion, but basic compute metrics do not reveal the needed guest measurements. What should be evaluated?
29. A volume is expanded in OCI, but the guest filesystem still reports its previous size. What may still be required?
30. After incident mitigation, which activity best improves operational reliability?
31. An administrator opens a network security group rule, but a different instance remains unreachable. What should be verified?
32. An application reports missing files after an Object Storage lifecycle policy change. What should the investigation include?
33. An application team needs separate development and production infrastructure from one module set. Which design is safest?
34. An archival object must be read immediately, but it is not currently restored. What operational issue should be anticipated?
35. An incident runbook automatically restarts unhealthy workers when an event arrives. What design is essential?
36. An instance pool's autoscaling policy never adds instances even during sustained high CPU. Which TWO checks are appropriate? Select TWO.
37. An OCI resource was changed manually after its last Terraform apply. What can help identify the divergence?
38. An on-call team receives no alarm notifications. Which TWO layers should be validated? Select TWO.
39. An operations team needs evidence of allowed and rejected network flows for a VCN investigation. Which telemetry should it evaluate?
40. An operator must investigate a sudden spending increase by application team. Which preparation is most useful?
41. An operator must review the effects of a Resource Manager configuration before changing production. Which job should run first?
42. An operator needs application error details alongside infrastructure metrics. Which approach is appropriate?
43. An operator plans to delete a customer-managed key used to encrypt production data. What should be checked first?
44. An operator restores a backup successfully. What should be verified before declaring recovery complete?
45. An operator updates an instance configuration used by a pool. What should be planned for existing instances?
46. Connectivity works in one direction only across a hybrid network. Which troubleshooting principle is most useful?
47. One instance behind a load balancer has high error rates after a release. What is the safest initial containment?
48. One side of a stateful inspection appliance sees traffic, but return packets take another route. What is the likely concern?
49. Several volumes hold interdependent application data. What should a backup strategy address?
50. Two engineers submit jobs to the same Resource Manager stack. Why must execution be coordinated?
