Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q82-Q87):

NEW QUESTION # 82
Which OCI service provides detailed logs for network traffic traversing a Network Load Balancer, offering insights into client connections and backend health checks?

A. Load Balancer Logs
B. Service Logs
C. Flow Logs
D. Audit Logs

Answer: A

Explanation:
* Objective: Identify the service for Load Balancer traffic logs.
* Option A: Flow Logs capture VCN traffic, not specific to Load Balancer-incorrect.
* Option B: Service Logs are generic, not Load Balancer-specific-incorrect.
* Option C: Load Balancer Logs provide detailed client and health check data-correct.
* Option D: Audit Logs track API actions, not traffic-incorrect.
* Conclusion: Load Balancer Logs are the best fit.
Oracle states:
* "Load Balancer Logs offer detailed insights into client connections and backend health checks for Network Load Balancers."This validates Option C. Reference:Load Balancer Logging - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Balance/Tasks/managinglogs.htm).

NEW QUESTION # 83
Which OCI component facilitates transitive routing between VCNs in different regions via a dedicated, private network backbone, while also enabling connectivity to on-premises networks?

A. Internet Gateway
B. Service Gateway
C. Dynamic Routing Gateway (DRG)
D. Local Peering Gateway (LPG)

Answer: C

Explanation:
* Requirement:Transitive routing across regions and to on-premises, privately.
* Components:
* LPG:Intra-region VCN peering; limited scope.
* DRG:Cross-region and on-premises routing via private backbone.
* Service Gateway:OCI service access; not transitive.
* Internet Gateway:Public internet; not private.
* Evaluate Options:
* A:Region-specific; incorrect.
* B:Supports multi-region and on-premises; correct.
* C:Service-focused; incorrect.
* D:Public; incorrect.
* Conclusion:DRG is the key component.
DRG enables complex routing scenarios. The Oracle Networking Professional study guide notes, "The Dynamic Routing Gateway (DRG) facilitates transitive routing between VCNs in different regions and on- premises networks over OCI's private backbone" (OCI Networking Documentation, Section: Dynamic Routing Gateway). This meets both requirements efficiently.

NEW QUESTION # 84
You are troubleshooting an issue where a compute instance in a private subnet within a VCN cannot reach OCI Object Storage. You have verified that a Service Gateway is configured for the VCN and that the route table associated with the subnet has a route rule directing traffic for OCI Services to the Service Gateway.
However, the instance still cannot connect. What is the MOST likely cause of the problem?

A. The Service Gateway is not configured to allow access to OCI Object Storage.
B. The security list or network security group associated with the subnet or instance is not configured to allow outbound traffic to the OCI Object Storage service CIDR block.
C. The instance requires a public IP address to access OCI Object Storage.
D. The instance is not configured with the Oracle Cloud Agent.

Answer: B

Explanation:
* Problem: Instance in private subnet can't reach Object Storage despite Service Gateway and routing.
* Option A: Service Gateway enables private access; public IP isn't required-incorrect.
* Option B: Security lists/NSGs act as firewalls; if outbound traffic to Object Storage CIDR isn't allowed, connectivity fails-most likely and correct.
* Option C: Service Gateway defaults to all OCI services unless restricted; less likely given setup verification-incorrect.
* Option D: Oracle Cloud Agent is for management, not connectivity-incorrect.
* Conclusion: Option B is the most probable cause.
Oracle states:
* "For private access to Object Storage via a Service Gateway, ensure security lists or NSGs allow outbound traffic to the Object Storage CIDR block."This supports Option B. Reference:Service Gateway Troubleshooting - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks
/servicegateway.htm#troubleshooting).

NEW QUESTION # 85
When setting up cross-tenancy VCN peering using Local Peering Gateways (LPGs), which IAM permission is required in the target tenancy to accept the peering request?

A. Allow group <group_name> to inspect local-peering-gateways in tenancy=<target_tenancy_OCID>
B. Allow group <group_name> to read virtual-network-family in tenancy=<target_tenancy_OCID>
C. Allow group <group_name> to manage local-peering-gateways in tenancy=<target_tenancy_OCID>
D. Allow group <group_name> to use local-peering-gateways in tenancy=<target_tenancy_OCID>

Answer: C

Explanation:
* Requirement: IAM permission to accept cross-tenancy LPG peering.
* Option A: "Manage" allows creating and accepting peering-correct.
* Option B: "Use" permits using existing LPGs, not accepting requests-incorrect.
* Option C: "Inspect" is read-only, insufficient-incorrect.
* Option D: "Read" on virtual-network-family doesn't cover LPG management-incorrect.
* Conclusion: Option A is required.
Oracle states:
* "To accept a cross-tenancy peering request, the target tenancy needs 'manage local-peering-gateways' permission."This confirms Option A. Reference:Local VCN Peering - Oracle Help Center(docs.oracle.
com/en-us/iaas/Content/Network/Tasks/localVCNpeering.htm).

NEW QUESTION # 86
You're tasked with creating a network diagnostic tool using Cloud Shell to test connectivity to various endpoints from within your VCN. To enhance security, you want to ensure the tool only has the necessary permissions to perform network diagnostics (e.g., ping, traceroute, nc). Which IAM principle and associated action(s) provide the MOST restrictive, least-privilege access for Cloud Shell to perform network diagnostic tasks?

A. An IAM user with the read permission on all virtual-network-family resources.
B. Cloud Shell session using Instance Principals, belonging to a dynamic group with a policy allowing network-security-groups and vnics to be read and used.
C. An IAM group with inspect permission on virtual-network-family in the target compartment.
D. An IAM group with the use permission on the virtual-network-family aggregate resource in the tenancy.

Answer: B

Explanation:
* Goal: Apply least privilege for Cloud Shell to run diagnostics (ping, traceroute, nc) within a VCN.
* Option A: Read permission on all virtual-network-family resources is too broad, granting unnecessary access beyond diagnostics-violates least privilege.
* Option B: Instance Principals use temporary credentials tied to the Cloud Shell instance, enhancing security. A dynamic group with "read" and "use" permissions on NSGs and VNICs allows inspecting configurations and running diagnostics (e.g., via VNICs), meeting the exact need-correct.
* Option C: Inspect permission only provides metadata access, insufficient for running diagnostics (e.g., no "use" for traffic)-incorrect.
* Option D: Use permission on virtual-network-family at tenancy level is overly permissive, granting access to all network resources-violates least privilege.
* Conclusion: Option B is the most restrictive and secure, aligning with least privilege.
Oracle states:
* "Instance Principals allow services like Cloud Shell to authenticate without static credentials. Policies with 'read' and 'use' on specific resources (e.g., network-security-groups, vnics) enable diagnostics while adhering to least privilege."This supports Option B. Reference:Instance Principals - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Identity/Tasks/instanceprincipals.htm).
