Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q109-Q114):NEW QUESTION # 109
You are responsible for managing access to an Oracle Autonomous Database (ADB) instance inyour OCI environment. You need to configure a secure connection to the ADB from compute instances located in a private subnet. You want to limit access to the ADB to only the designated compute instances. Which type of endpoint, in conjunction with appropriate security rules, provides the MOST granular control over network access to the Autonomous Database?
  • A. A Service Gateway-enabled connection with a Service Gateway configured to allow access to ADB.
  • B. A Dynamic Routing Gateway (DRG) connection with appropriate route rules.
  • C. A private ADB endpoint with Network Security Groups (NSGs) restricting access.
  • D. A public ADB endpoint with Network Security Groups (NSGs) restricting access.
Answer: C
Explanation:
* Goal: Secure, granular access control to ADB from private subnet instances.
* Option A: Public endpoint with NSGs exposes ADB to the internet, increasing risk despite NSG restrictions-less secure than private options.
* Option B: Service Gateway provides private access to OCI services, but it's not specific to ADB instances and lacks the instance-level granularity of private endpoints.
* Option C: Private ADB endpoint assigns a private IP within the VCN, keeping traffic internal. NSGs allow precise, stateful control to specific instances, offering the most granular security.
* Option D: DRG is for external connections (e.g., on-premises), not internal VCN-to-ADB access.
* Conclusion: Option C provides the most secure and granular control.
Oracle documentation notes:
* "Private endpoints for Autonomous Database provide a private IP within your VCN, ensuring traffic stays off the public internet. Use NSGs for fine-grained access control to specific instances."This supports Option C. Reference:Autonomous Database Networking - Oracle Help Center(docs.oracle.com
/en-us/iaas/Content/Database/Tasks/adbconnecting.htm).

NEW QUESTION # 110
A development team has deployed a three-tier application in an OCI VCN. The application consists of a public-facing web tier, an application tier, and a database tier. The team reports that the web tier instances can communicate with the application tier instances, but the application tier instances cannot connect to the database tier instances. All security lists are configured to allow all traffic within the VCN. Which OCI Networking diagnostic tool would BEST help you quickly isolate the root cause of this connectivity issue?
  • A. Connection Diagnostics
  • B. VCN Flow Logs
  • C. Network Firewall
  • D. OCI Bastion
Answer: A
Explanation:
* Problem: App tier can't reach DB tier despite open security lists.
* Option A: Flow Logs show traffic details but require analysis, slowing diagnosis-less efficient.
* Option B: Connection Diagnostics tests connectivity (e.g., ping, traceroute) between resources, quickly pinpointing failures-correct.
* Option C: Network Firewall controls traffic, not diagnoses-incorrect.
* Option D: Bastion is for access, not troubleshooting-incorrect.
* Conclusion: Connection Diagnostics is the best tool for quick isolation.
Oracle states:
* "Connection Diagnostics provides rapid testing of network connectivity between OCI resources, ideal for isolating issues like tier-to-tier failures."This validates Option B. Reference:Network Troubleshooting - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks
/troubleshooting.htm#connectiondiagnostics).

NEW QUESTION # 111
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 using a third-party WAN optimization solution.
  • B. Determine the pricing scheme used for all OCI compute resources so you can predict when you need to scale bandwidth.
  • C. Deploy a dedicated interconnect through a network service provider that specializes in connecting OCI and AWS.
  • D. Evaluate the distance between the OCI and AWS regions you are using.
Answer: B
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 # 112
Which OCI service or feature is best suited for capturing and analyzing network traffic metadata to identify anomalies and troubleshoot connectivity issues between VCN resources?
  • A. Flow Logs
  • B. Service Gateway
  • C. Route Tables
  • D. Network Security Groups (NSGs)
Answer: A
Explanation:
* Goal: Capture and analyze traffic metadata for anomalies and troubleshooting.
* Option A: NSGs control traffic but don't capture metadata-incorrect.
* Option B: Flow Logs record detailed traffic metadata (e.g., IPs, ports), perfect for analysis-correct.
* Option C: Route Tables manage routing, not metadata-incorrect.
* Option D: Service Gateway enables service access, not traffic logging-incorrect.
* Conclusion: Flow Logs are best suited.
Oracle documentation confirms:
* "Flow Logs capture network traffic metadata within a VCN, enabling anomaly detection and connectivity troubleshooting."This supports Option B. Reference:Flow Logs Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/flowlogs.htm).

NEW QUESTION # 113
You're designing a multi-region deployment of your application on OCI. You want to use OCI's global load balancing capabilities, but also require the WAF to protect against attacks close to the user. Which configuration provides the best balance between global load balancing and regional WAF protection?
  • A. Configure the WAF in front of the OCI GLB itself to inspect all traffic globally.
  • B. Configure the OCI GLB to distribute traffic based on source IP address to specific regions, and enable WAF on the regional Load Balancer.
  • C. Use OCI GLB to distribute traffic to regional Load Balancers, each fronted by a regional WAF.
  • D. Use OCI Global Load Balancer (GLB) with a single regional WAF protecting the backend servers in one region.
Answer: C
Explanation:
* Goal: Balance global load balancing with regional WAF protection near users.
* Option A: Single WAF in one region creates a bottleneck and increases latency-insufficient.
* Option B: GLB distributes globally to regional Load Balancers, each with a WAF, ensuringprotection close to users-correct.
* Option C: WAF before GLB centralizes protection, adding latency and a single failure point-incorrect.
* Option D: Source IP routing with regional WAFs is less optimal than GLB's health-based routing- less effective.
* Conclusion: Option B optimizes both goals.
Oracle states:
* "OCI GLB distributes traffic across regions. Pair with regional Load Balancers and WAFs for localized protection and optimal performance."This supports Option B. Reference:Global Load Balancer Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Balance/Concepts/globalbalance.
