Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q115-Q120):NEW QUESTION # 115
You are using the OCI Application Load Balancer (ALB) for your web application. You want to implement a blue/green deployment strategy to minimize downtime during application updates. You have two backend sets: 'blue' (the current version) and 'green' (the new version). What is the most efficient way to switch traffic from the 'blue' backend set to the 'green' backend set using the ALB's traffic management capabilities?
  • A. Use the ALB's routing rules to gradually shift traffic from the 'blue' backend set to the 'green' backend set based on a percentage weight.
  • B. Update the listener to point directly to the 'green' backend set.
  • C. Update the health check policy of the 'blue' backend set to mark all servers as unhealthy, forcing the ALB to send traffic to the 'green' backend set.
  • D. Create a new listener that points to the 'green' backend set and delete the old listener.
Answer: A
Explanation:
* Goal:Minimize downtime in blue/green deployment with ALB.
* ALB Capabilities:Supports weighted routing for gradual traffic shifts.
* Evaluate Options:
* A:Immediate switch risks downtime if 'green' fails; less efficient.
* Bistener swap causes abrupt change; not optimal.
* C:Gradual shift with weights ensures smooth transition; most efficient.
* D:Forcing 'blue' unhealthy is disruptive and hacky; inefficient.
* Conclusion:Weighted routing provides the smoothest transition.
ALB supports blue/green via routing rules. The Oracle Networking Professional study guide states,
"Application Load Balancer's routing rules allow weighted traffic distribution between backend sets, enabling blue/green deployments with minimal downtime" (OCI Networking Documentation,Section: Load Balancer Routing). This method ensures stability during updates.

NEW QUESTION # 116
You are designing a hybrid cloud architecture connecting your on-premises network to OCI. You have established a Site-to-Site VPN between your on-premises network and an OCI DRG. You have two VCNs attached to the DRG: VCN-A (10.0.0.0/16) and VCN-B (10.1.0.0/16). You need to ensure that only VCN-A can communicate with the on-premises network (192.168.1.0/24), while VCN-B should remain isolated. What is the MOST effective and secure method to achieve this connectivity requirement using DRG route tables?
  • A. Create two DRG route tables: DRG-RT-A and DRG-RT-B. In DRG-RT-A, add a route rule for
    192.168.1.0/24 pointing to the VPN attachment. Associate DRG-RT-A with the VCN-A attachment.
    Associate DRG-RT-B (containing no routes for 192.168.1.0/24) with the VCN-B attachment.
  • B. Create a single DRG route table. Add a route rule to the DRG route table for 192.168.1.0/24 pointing to the VPN attachment. Associate this route table with both the VCN-A and VCN-B attachments.
    Implement Network Security Groups (NSGs) on VCN-B to block all traffic to and from 192.168.1.0/24.
  • C. Create a single DRG route table. Add a route rule to the DRG route table for 192.168.1.0/24 pointing to the VPN attachment. Associate this route table with the VCN-A attachment. Associate a default DRG route table that contains no routes for the VPN attachment with the VCN-Battachment.
  • D. Create two DRG route tables: DRG-RT-A and DRG-RT-B. In DRG-RT-A, add a route rule for
    192.168.1.0/24 pointing to the VPN attachment. Associate DRG-RT-A with the VCN-A attachment. In DRG-RT-B, add a route rule for 192.168.1.0/24 pointing to the VPN attachment and associate DRG- RT-B with the VCN-B attachment. Then, use security lists to block all traffic between VCN-B and the on-premises network.
Answer: A
Explanation:
* Objective: Allow VCN-A to access on-premises (192.168.1.0/24) via VPN, isolate VCN-B using DRG route tables effectively and securely.
* Option A: Single route table for both VCNs with NSGs on VCN-B to block traffic. This works but relies on NSGs, which are secondary to routing. Routing-level isolation is more secure and efficient.
* Option B: Single route table for VCN-A with the VPN route, default table (no VPN route) for VCN-B.
This isolates VCN-B effectively at the routing level, but managing one table across all attachments can complicate scaling.
* Option C: Two route tables, both with VPN routes, then blocking VCN-B with security lists. This is inefficient-routes are advertised unnecessarily, relying on security lists instead of routing isolation.
* Option D: Two route tables-DRG-RT-A with VPN route for VCN-A, DRG-RT-B with no VPN route for VCN-B. This ensures VCN-B has no path to on-premises at the DRG level, providing the strongest isolation.
* Conclusion: Option D is the most effective and secure, leveraging routing for isolation rather than secondary security controls.
Oracle documentation states:
* "DRG route tables control traffic between VCN attachments and external connections (e.g., VPN).
Associate a unique route table with each attachment to enforce specific routing policies."
* "To isolate a VCN, ensure its DRG route table contains no routes to the destination."Option D aligns with this approach. Referenceynamic Routing Gateway Overview - Oracle Help Center(docs.oracle.
com/en-us/iaas/Content/Network/Tasks/managingDRGs.htm).

NEW QUESTION # 117
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. A Service Gateway configured with a Service CIDR label that includes the third-party API's IP address.
  • B. An Internet Gateway with a security list allowing outbound traffic to 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.
Reference:NAT Gateway Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network
/Tasks/NATgateway.htm).

NEW QUESTION # 118
In a multi-tier application environment with geographically dispersed teams requiring access to private resources, how can an OCI Bastion service be optimized to reduce latency for remote users?
  • A. Implementing Bastion hosts in multiple regions closer to user locations.
  • B. Configuring a Bastion service with a public load balancer.
  • C. Deploying a single Bastion host in the primary application region.
  • D. Using dynamic port forwarding to allow direct connections to private resources.
Answer: A
Explanation:
* Objective: Reduce latency for remote users accessing private resources via Bastion.
* Option A: Single Bastion increases latency for distant users-incorrect.
* Option B: Multiple regional Bastions minimize latency by proximity-correct.
* Option C: Dynamic port forwarding doesn't address geographic latency-incorrect.
* Option D: Load balancer aids HA, not latency reduction-incorrect.
* Conclusion: Option B optimizes latency.
Oracle notes:
* "Deploy Bastion hosts in multiple regions to reduce latency for geographically dispersed users accessing private resources."This supports Option B. Reference:Bastion Service Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Bastion/Concepts/bastionoverview.htm).

NEW QUESTION # 119
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 group with the use permission on the virtual-network-family aggregate resource in the tenancy.
  • B. An IAM group with inspect permission on virtual-network-family in the target compartment.
  • C. 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.
  • D. An IAM user with the read permission on all virtual-network-family resources.
Answer: C
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).
