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

NEW QUESTION # 24
Your company utilizes a hybrid cloud architecture, connecting its on-premises network to an OCIVCN using a FastConnect private peering connection. You need to ensure that instances within a specific subnet in the VCN can only communicate with resources in a designated IP address range within the on-premises network.
What is the MOST effective way to achieve this specific network isolation?

  • A. Configure a Local Peering Gateway (LPG) for the subnet to route traffic to the on-premises network.
  • B. Modify the VCN's default security list to restrict traffic to the on-premises IP address range.
  • C. Create a custom route table for the subnet with a route rule pointing to the Dynamic Routing Gateway (DRG) and configure network security groups (NSGs) to limit traffic to the specified on-premises IP address range.
  • D. Configure an Internet Gateway for the subnet with a route rule to the on-premises network.

Answer: C

Explanation:
* Goal: Restrict subnet traffic to a specific on-premises IP range via FastConnect.
* Option A: Internet Gateway is for public access, not FastConnect-incorrect.
* Option B: Default security list applies broadly, lacking granularity; NSGs are more effective-less optimal.
* Option C: Custom route table with DRG ensures FastConnect routing; NSGs provide precise, instance- level traffic restriction-correct.
* Option D: LPG is for same-region VCN peering, not on-premises-incorrect.
* Conclusion: Option C is the most effective method.
Oracle notes:
* "Use a custom route table with a DRG route rule for FastConnect traffic. NSGs offer granular control to restrict traffic to specific IP ranges."This supports Option C. Reference:FastConnect and NSG Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm & docs.oracle.com/en-us/iaas/Content/Network/Concepts/NSGs.htm).


NEW QUESTION # 25
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 # 26
Your company has established a hybrid cloud environment using FastConnect to connect your on-premises network to your OCI VCN. You are advertising on-premises network prefixes to OCI via BGP. You want to ensure that OCI only learns routes from your on-premises network that are within a specific range, and that any other prefixes advertised are rejected to prevent routing conflicts. Which BGP attribute and configuration on the OCI side should you use to achieve this?

  • A. Route Filtering using Route Distinguisher (RD) and Route Target (RT): Configure RDs and RTs on the FastConnect virtual circuit to filter routes based on tenant isolation.
  • B. MED (Multi-Exit Discriminator): Configure MED values on the on-premises BGP router toinfluence OCI's route selection based on preferred exit points.
  • C. Route Filtering using Prefix Lists: Configure Prefix Lists on the FastConnect virtual circuit to accept only the desired prefix ranges and reject all others.
  • D. AS Path Prepending: Configure AS Path Prepending on the FastConnect virtual circuit to discourage OCI from selecting routes outside the desired range.

Answer: C

Explanation:
* Objective:Filter BGP routes on OCI to accept only specific on-premises prefixes.
* BGP Attributes Overview:
* AS Path Prepending:Lengthens AS path to influence route preference, not filtering.
* MED:Influences exit point selection, not route acceptance.
* RD/RT:Used in MPLS VPNs for tenant isolation, not simple prefix filtering.
* Prefix Lists:Directly filter prefixes based on IP ranges.
* Evaluate Options:
* A:AS Path Prepending affects preference, not filtering; unsuitable.
* B:MED influences path selection, not route rejection; incorrect.
* C:RD/RT is for VPN contexts, not applicable here.
* D:Prefix Lists explicitly allow/deny prefixes, meeting the requirement.
* Conclusion:Prefix Lists on the FastConnect virtual circuit provide precise control over accepted routes.
Prefix Lists are the most effective BGP tool for filtering routes in OCI. The Oracle Networking Professional study guide notes, "Prefix Lists can be applied to FastConnect virtual circuits to filter BGP advertisements, ensuring only approved prefixes are learned by OCI" (OCI Networking Documentation, Section: FastConnect and BGP). This prevents routing conflicts by rejecting unwanted prefixes, aligning with the security and control requirements.


NEW QUESTION # 27
Your company has two FastConnect circuits connecting your on-premises network to OCI. You want to implement a BGP configuration that ensures that traffic from OCI to your on-premises network is load- balanced across both FastConnect circuits. Which BGP configuration would BEST achieve load balancing across the two FastConnect circuits?

  • A. Configure AS Path Prepending on one of the FastConnect virtual circuits.
  • B. Advertise the same prefixes with the same attributes (including AS Path) across both FastConnect circuits.
  • C. Configure different MED values on each FastConnect virtual circuit.
  • D. Configure local preference to be higher on one of the FastConnect virtual circuits.

Answer: B

Explanation:
* Objective: Load balance OCI-to-on-premises traffic over two FastConnect circuits.
* Option A: Different MEDs prioritize one path, not balance-incorrect.
* Option B: Same prefixes and attributes enable Equal-Cost Multi-Path (ECMP) routing, balancing traffic-correct.
* Option C: AS Path Prepending prefers one path-incorrect.
* Option D: Local preference prioritizes one path-incorrect.
* Conclusion: Option B ensures load balancing.
Oracle states:
* "For load balancing over multiple FastConnect circuits, advertise identical prefixes with the same BGP attributes to enable ECMP."This supports Option B. Reference:FastConnect BGP - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#BGP).


NEW QUESTION # 28
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 instance requires a public IP address to access 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 Service Gateway is not configured to allow access to 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).
