Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q118-Q123):

NEW QUESTION # 118
A large financial institution is migrating its on-premises trading platform to OCI. The platform requires low latency and high bandwidth connectivity to the on-premises data center. You have established an Oracle Cloud Infrastructure FastConnect circuit. You now need to connect multiple VCNs in different regions to the on-premises data center via this FastConnect circuit, optimizing for cost and management overhead. Which DRG configuration would be the most efficient and recommended approach?

  • A. Create a single DRG in one region and attach all VCNs in all regions to this single DRG using remote peering connections. Attach the FastConnect circuit to this single DRG. Configure static routes on the DRG to direct traffic to the appropriate VCNs.
  • B. Create a single DRG in one region and attach all VCNs in all regions to this single DRG using local peering gateways (LPGs). Attach the FastConnect circuit to this single DRG. Configure static routes on the DRG to direct traffic to the appropriate VCNs.
  • C. Create a single DRG in one region. Attach all VCNs in all regions to this single DRG using DRG attachments with remote peering. Attach the FastConnect circuit to the single DRG.
  • D. Create a separate DRG in each region and attach each VCN to its regional DRG. Then, create a separate FastConnect attachment to each regional DRG. Finally, configure static routes on each DRG to direct traffic appropriately.

Answer: C

Explanation:
* Requirements:Low latency, high bandwidth, multi-region VCNs via one FastConnect, minimal cost
/overhead.
* DRG Strategy:
* Multiple DRGs:Increases cost and complexity.
* Single DRG:Centralizes management, reduces FastConnect attachments.
* Evaluate Options:
* A:Multiple DRGs and FastConnects; costly and complex; incorrect.
* B:Remote peering connections imply RPC, not standard DRG attachments; less precise.
* C:Single DRG with remote peering attachments; efficient and correct terminology; optimal.
* D:LPGs are intra-region, not cross-region; incorrect.
* Conclusion:Single DRG with remote peering attachments is most efficient.
A single DRG optimizes multi-region setups. The Oracle Networking Professional study guide notes, "For connecting multiple VCNs across regions to a single FastConnect, use one DRG with remote peering attachments to minimize cost and management overhead" (OCI Networking Documentation, Section: DRG with FastConnect). Option C aligns with OCI's recommended architecture.


NEW QUESTION # 119
You are designing a highly available web application in OCI. You've created a VCN with two public subnets across different Availability Domains (ADs). You need to enable IPv6 support for the application to cater to a growing number of IPv6-only clients. You plan to use a Load Balancer to distribute traffic to backend compute instances in the public subnets. Which of the following approaches ensures the highest level of resilience and IPv6 connectivity for your application?

  • A. Configure the VCN with a /48 IPv6 ULA prefix. Configure the Load Balancer to listen on IPv4 only, and the compute instances to listen on both IPv4 and IPv6, relying on NAT for IPv6 clients.
  • B. Configure the VCN with a public IPv6 CIDR block obtained from Oracle. Configure the Load Balancer to listen on both IPv4 and IPv6 addresses. Ensure the backend compute instances also listen on both IPv4 and IPv6 addresses.
  • C. Configure the VCN with a /48 IPv6 ULA prefix. Configure the Load Balancer to listen on both IPv4 and IPv6 addresses. Ensure the backend compute instances also listen on both IPv4 and IPv6 addresses.
    Route traffic accordingly using NSGs.
  • D. Configure the VCN with a public IPv6 CIDR block obtained from Oracle. Configure the Load Balancer to listen on IPv4 only, while backend compute instances listen on both IPv4 and IPv6, relying on NAT for IPv6 clients.

Answer: B

Explanation:
* Requirements: HA and IPv6 support for public web app.
* Option A: ULA is private, not routable; NAT for IPv6 is inefficient-incorrect.
* Option B: ULA doesn't support public IPv6 clients-incorrect.
* Option C: Public IPv6 CIDR is correct, but IPv4-only LB with NAT lacks direct IPv6-less resilient.
* Option D: Public IPv6 CIDR with dual-stack LB and instances ensures full IPv6 support and HA across ADs-correct.
* Conclusion: Option D maximizes resilience and connectivity.
Oracle states:
* "For public IPv6 applications, use a public IPv6 CIDR block and configure Load Balancers and instances for both IPv4 and IPv6 to ensure resilience."This supports Option D. Reference:IPv6 in OCI - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/managingIPv6.htm).


NEW QUESTION # 120
Your security team has mandated that all traffic to Oracle Cloud Infrastructure Object Storage must be encrypted end-to-end and must not be routed over the public internet. You are designing asolution where compute instances within a private subnet will frequently upload and download data from Object Storage.
Which of the following options provides the most secure and compliant solution?

  • A. Configure a Service Gateway to Object Storage and enable encryption at rest on the Object Storage bucket.
  • B. Configure a Service Gateway to Object Storage and ensure all API calls to Object Storage are made over HTTPS.
  • C. Configure a NAT Gateway for the instances and enable encryption in transit using HTTPS for all Object Storage API calls.
  • D. Configure a Private Endpoint to Object Storage and ensure all API calls to Object Storage are made over HTTPS.

Answer: B

Explanation:
* Requirements:End-to-end encryption, no public internet for Object Storage access.
* Options Analysis:
* Service Gateway:Private access to Object Storage.
* NAT Gateway:Public internet access; unsuitable.
* Private Endpoint:Alternative private access, but newer feature.
* HTTPS:Ensures in-transit encryption.
* Evaluate Options:
* A:Encryption at rest doesn't cover transit; incomplete.
* B:NAT uses public internet; violates policy; incorrect.
* C:Service Gateway with HTTPS ensures full encryption and privacy; correct.
* D:Private Endpoint with HTTPS is valid but less common than Service Gateway; slightly less optimal historically.
* Conclusion:Service Gateway with HTTPS is most secure and compliant.
Service Gateway is standard for private Object Storage access. The Oracle Networking Professional study guide states, "A Service Gateway with HTTPS API calls ensures end-to-end encrypted traffic to Object Storage without public internet traversal" (OCI Networking Documentation, Section: Service Gateway). This meets security mandates effectively.


NEW QUESTION # 121
You are configuring a VCN with multiple subnets for a customer. The security team requires that all instances have IPv6 addresses. You configure the VCN with an IPv6 ULA CIDR block of fc00:1:1::/48 and create two private subnets. After launching instances in the two private subnets, you notice that they only have IPv4 addresses assigned. You have not manually configured any IPv6 addresses on the instances themselves. What steps are necessary to ensure the instances automatically receive IPv6 addresses?

  • A. No further steps are needed. Instances will automatically receive IPv6 addresses within the configured subnets upon launch.
  • B. Make sure the "Assign public IPv4 address" option is not selected during instance creation. This will force the instance to default to IPv6 allocation.
  • C. Ensure that SLAAC (Stateless Address Autoconfiguration) is enabled on the operating system of the instances within the two subnets.
  • D. IPv6 address assignment is only supported on instances launched in public subnets.

Answer: C

Explanation:
* Problem:Instances lack IPv6 addresses despite VCN IPv6 configuration.
* OCI IPv6 Behavior:IPv6 requires subnet enablement and OS support via SLAAC.
* Evaluate Options:
* A:Incorrect. OCI doesn't auto-assign IPv6 without OS configuration.
* B:Correct. SLAAC must be enabled on the instance OS for auto-assignment.
* C:Incorrect. IPv6 works in both public and private subnets.
* D:Incorrect. IPv4 and IPv6 assignments are independent.
* Conclusion:Enabling SLAAC on the OS ensures automatic IPv6 assignment.
IPv6 in OCI relies on SLAAC for automatic address assignment. The Oracle Networking Professional study guide states, "To enable IPv6 on instances, the VCN and subnet must have IPv6 CIDR blocks, and the instance OS must support SLAAC to automatically configure IPv6 addresses" (OCI Networking Documentation, Section: IPv6 Configuration). Without SLAAC, instances default to IPv4 only.


NEW QUESTION # 122
You are tasked with setting up a secure connection from an OCI Compute instance running in a private subnet to a third-party API that is only accessible over the internet via a static public IP address. Your company policy prohibits exposing the compute instance directly to the internet. Which combination of VCN resources BEST facilitates this secure outbound connection to the third-party API?

  • A. An Internet Gateway with a security list allowing outbound traffic to the third-party API's IP address.
  • B. A Service Gateway configured with a Service CIDR label that includes the third-party API's IP address.
  • C. A NAT Gateway and a security list allowing outbound traffic to the third-party API's IP address.
  • D. A Dynamic Routing Gateway (DRG) connected to a FastConnect circuit, with routes configured to direct traffic to the third-party API's IP address.

Answer: C

Explanation:
* Requirement: Secure outbound connection to a public API without exposing the instance.
* Option A: Internet Gateway allows inbound and outbound traffic, exposing the instance-violates policy.
* Option B: NAT Gateway enables outbound-only internet access from a private subnet. A security list restricts traffic to the API's IP, ensuring security-correct.
* Option C: Service Gateway is for OCI services, not third-party APIs-incorrect.
* Option D: DRG with FastConnect is for private connections (e.g., on-premises), not internet APIs- incorrect.
* Conclusion: Option B meets the policy and connectivity needs.
Oracle notes:
* "A NAT Gateway allows instances in a private subnet to initiate outbound internet traffic without receiving inbound connections. Use security lists to restrict destinations."This supports Option B.
