Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q24-Q29):

NEW QUESTION # 24
Your organization uses a combination of OCI and AWS. Applications in OCI frequently access services hosted in AWS. You are experiencing slow and inconsistent data transfer speeds when transferring large files between the two clouds. You have a Site-to-Site VPN, but are considering other options. Which option is NOT a valid design consideration for improving the data transfer performance between OCI and AWS?

  • A. Evaluate the distance between the OCI and AWS regions you are using.
  • B. Deploy a dedicated interconnect through a network service provider that specializes in connecting OCI and AWS.
  • C. Determine the pricing scheme used for all OCI compute resources so you can predict when you need to scale bandwidth.
  • D. Evaluate using a third-party WAN optimization solution.

Answer: C

Explanation:
* Objective: Improve OCI-AWS data transfer performance.
* Option A: Region distance affects latency-valid.
* Option B: Dedicated interconnect boosts bandwidth and stability-valid.
* Option C: Compute pricing doesn't influence inter-cloud bandwidth-invalid.
* Option D: WAN optimization can enhance transfer efficiency-valid.
* Conclusion: Option C is not a design consideration for performance.
Oracle notes:
* "To optimize OCI-AWS connectivity, consider region proximity, dedicated interconnects, or WAN optimization. Compute pricing is unrelated to network performance."This excludes Option C.

/Concepts/hybridcloud.htm).


NEW QUESTION # 25
Your company is migrating its publicly accessible website to OCI. You want to ensure the highest level of security and prevent DNS spoofing or cache poisoning attacks. You've decided to implement DNSSEC.
Which of the following is the most important first step in enabling DNSSEC for your domain using OCI DNS?

  • A. Enable DNSSEC on the OCI DNS zone for your domain and obtain the Delegation Signer (DS) record from OCI DNS.
  • B. Create a Traffic Management Steering Policy with the "DNSSEC" option enabled.
  • C. Generate a Key Signing Key (KSK) and a Zone Signing Key (ZSK) using a third-party tool and upload them to OCI DNS.
  • D. Configure the OCI DNS resolver to validate all incoming DNS responses using DNSSEC.

Answer: A

Explanation:
* Objective:Enable DNSSEC to secure OCI DNS against spoofing.
* DNSSEC Process:Requires enabling on the zone, generating keys, and updating the registrar.
* Evaluate Options:
* A:Steering policies manage traffic, not DNSSEC; incorrect.
* B:OCI DNS auto-generates keys; manual upload unnecessary; incorrect.
* C:Enabling DNSSEC starts the process, provides DS record; correct first step.
* D:Resolver validation is client-side, not enabling DNSSEC; incorrect.
* Conclusion:Enabling DNSSEC on the zone is the critical first step.
DNSSEC setup begins at the zone level. The Oracle Networking Professional study guide states, "The first step to enable DNSSEC in OCI DNS is to activate it on the zone, which generates keys and provides a DS record to share with your registrar" (OCI Networking Documentation, Section: DNSSEC Configuration). This establishes the chain of trust.


NEW QUESTION # 26
In a multi-region OCI environment, which configuration is necessary to allow communication between two VCNs located in different regions through a DRG?

  • A. Attaching a Service Gateway to each VCN and enabling transitive routing.
  • B. Configuring Internet Gateways on each VCN and using public IP addresses for communication.
  • C. Attaching an LPG to each VCN and configuring route tables to peer them directly.
  • D. Attaching each VCN to the same DRG and configuring the appropriate route tables on the DRG.

Answer: D

Explanation:
* Requirement: Private communication between VCNs in different OCI regions via DRG.
* Option A: LPGs are for same-region VCN peering, not cross-region-incorrect.
* Option B: Service Gateways are for OCI service access, not VCN-to-VCN routing-incorrect.
* Option C: Attaching both VCNs to a single DRG (via Remote Peering Connections implicitly) and configuring route tables enables cross-region communication over OCI's backbone. This is the standard approach.
* Option D: Internet Gateways use public IPs, which is insecure and not private-incorrect.
* Conclusion: Option C is the necessary configuration for DRG-based cross-region connectivity.
Oracle documentation confirms:
* "To connect VCNs in different regions, attach each to a DRG using Remote Peering Connections (RPCs). Configure DRG route tables to route traffic between VCN CIDRs."Option C reflects this setup (RPCs are implied). Reference:VCN Peering Overview - Oracle Help Center(docs.oracle.com/en-us/iaas
/Content/Network/Tasks/remoteVCNpeering.htm).


NEW QUESTION # 27
When troubleshooting inter-region connectivity issues between VCNs peered via a Dynamic Routing Gateway (DRG), which OCI tool is most effective for verifying the routing configuration and identifying potential misconfigurations?

  • A. DRG Route Tables
  • B. Oracle Cloud Guard
  • C. Network Visualizer
  • D. OCI Audit Logs

Answer: A

Explanation:
* Goal: Verify routing for inter-region VCN peering via DRG.
* Option A: Cloud Guard monitors security, not routing-incorrect.
* Option B: Audit Logs track changes, not current routing state-incorrect.
* Option C: DRG Route Tables define routing rules, directly showing misconfigurations-correct.
* Option D: Network Visualizer shows topology but not detailed routing rules-less effective.
* Conclusion: DRG Route Tables are most effective.
Oracle states:
* "DRG Route Tables are the primary tool for verifying and troubleshooting routing configurations for inter-region VCN peering."This validates Option C. Reference:DRG Troubleshooting - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/managingDRGs.htm#troubleshooting).


NEW QUESTION # 28
When establishing cross-tenancy connectivity using Remote Peering Connections (RPCs), which IAM policy statement is essential to grant the requesting tenancy the ability to initiate the connection?

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

Answer: D

Explanation:
* Objective:Grant requesting tenancy permission to initiate an RPC to the target tenancy.
* RPC Process:Requires the requesting tenancy to create and connect the RPC, which needs specific IAM permissions in the target tenancy.
* IAM Verbs:
* manage:Broad permissions, too permissive for RPC initiation.
* use:Allows creation and connection of RPCs, precise for this task.
* inspect:Read-only, insufficient for initiating connections.
* read:Read-only, insufficient for initiating connections.
* Evaluate Options:
* A:Too broad, includes unnecessary permissions; incorrect.
* B:Precise permission for RPC initiation; correct.
* C:Read-only, doesn't allow connection; incorrect.
* D:Read-only, doesn't allow connection; incorrect.
* Conclusion:"use remote-peering-connections" is the essential policy.
RPCs require specific IAM policies for cross-tenancy connectivity. The Oracle Networking Professional study guide states, "To initiate a Remote Peering Connection, the requesting tenancy needs an IAM policy with the 'use remote-peering-connections' verb targeting the acceptor tenancy's OCID" (OCI Networking Documentation, Section: Remote Peering Connections). This ensures controlled access for connection establishment.
