1Z0-1072-26 OCI Architect Associate Practice Test

Answer choices

1. A. Choose a nonoverlapping CIDR for the analytics VCN, such as 10.30.0.0/16, before creating the peering relationship.
2. B. Keep 10.20.64.0/18 and add a more-specific route on both VCNs after the peering is created.
3. C. Keep the overlapping CIDRs and rely on network security groups to distinguish traffic between the two VCNs.
4. D. Create the peering first, then use a NAT gateway in each VCN to translate all inter-VCN traffic.

Wrong-answer review

• B. Keep 10.20.64.0/18 and add a more-specific route on both VCNs after the peering is created.: More-specific routes do not make overlapping VCN address spaces valid for peering.
• C. Keep the overlapping CIDRs and rely on network security groups to distinguish traffic between the two VCNs.: NSGs filter traffic; they do not resolve ambiguous overlapping address spaces.
• D. Create the peering first, then use a NAT gateway in each VCN to translate all inter-VCN traffic.: NAT gateways provide outbound translation to the internet and are not the remedy for overlapping peered VCN CIDRs.

Answer choices

1. A. Create a NAT gateway timeout because NAT sessions can expire Object Storage objects.
2. B. Create a compartment quota because quotas delete resources once their age exceeds the quota period.
3. C. Use Object Lifecycle Management with age-based rules for current and previous object versions.
4. D. Create a DRG import policy because route distributions can delete stale object versions.

Answer choices

1. A. Disable all route tables in the hub so OCI automatically sends packets through the only firewall VNIC.
2. B. Use a service gateway because service gateways inspect traffic between private VCN address spaces.
3. C. Rely on security lists to rewrite the next hop whenever a packet enters the hub subnet.
4. D. Route intra-VCN and DRG traffic through the firewall private IP or attachment as the next hop.

Answer choices

1. A. Use OCI File Storage, expose the file system through a mount target and NFS export, and mount it from the clients.
2. B. Use one Block Volume with ordinary ext4 mounted read/write independently on every instance without clustering.
3. C. Use Object Storage as a raw POSIX block device attached through iSCSI.
4. D. Use Archive Storage and mount archived objects directly with the Linux NFS client.

Answer choices

1. A. Double the instance size because absent metrics always mean CPU exhaustion.
2. B. Delete the resource because OCI never resumes metric publication after a single gap.
3. C. Check the metric namespace, dimensions, time window, and Monitoring configuration first.
4. D. Create a public IP because Monitoring metrics require internet-routable resources.

Answer choices

1. A. Validate only the subnet route table; image architecture is translated automatically by OCI.
2. B. Validate the cost report because billing data determines whether an image can boot on Arm.
3. C. Validate that the image and operating system are compatible with the target processor architecture.
4. D. Validate that the image's security list is stateless, because stateful rules prevent cross-architecture boot.

Answer choices

1. A. Keep the policy and add a free-form tag named `LeastPrivilege=true` to the group.
2. B. Keep the tenancy scope but change `manage` to `inspect`, because instance administration requires only metadata access.
3. C. Move AppProd into a new VCN because VCN boundaries automatically override excessive IAM policies.
4. D. Replace the tenancy-wide all-resources grant with permissions limited to the required Compute resource types in compartment AppProd.

Answer choices

1. A. Use Autonomous AI Database.
2. B. Use Base Database Service because it requires no database administration and hides all configuration from the customer.
3. C. Use Oracle NoSQL Database because it provides full Oracle SQL relational compatibility and RAC administration.
4. D. Use a self-managed compute VM because it removes operating-system and database patching responsibility from the customer.

Answer choices

1. A. Keep the workflow unchanged because usage reports remain the only cost and consumption reporting format.
2. B. Replace the reports with Monitoring CPU metrics because operational metrics are equivalent to billed usage.
3. C. Migrate the workflow to current cost reports or Cost Analysis because legacy usage reports were deprecated.
4. D. Replace the reports with compartment quotas because quotas contain historical line-item costs.

Answer choices

1. A. Select any flexible VM shape because flexible shapes remove the hypervisor.
2. B. Select a bare metal shape.
3. C. Select a burstable VM because burstable mode provides direct physical host ownership.
4. D. Select an instance pool because pools automatically convert VMs into bare metal instances.
