Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q32-Q37):NEW QUESTION # 32
You are managing an OCI Network Firewall that protects a VCN with multiple subnets. The application team reports intermittent connectivity issues to a specific application server behind the firewall. You suspect the issue might be related to the firewall's stateful inspection. What would be the most efficient way to troubleshoot if the stateful inspection is causing these connectivity issues?
  • A. Disable stateful inspection on the entire Network Firewall to check if the connectivity is restored.
  • B. Review the Network Firewall logs for denied traffic originating from or destined to the application server.
  • C. Recreate the Network Firewall with a completely different configuration.
  • D. Create a Network Firewall policy with a specific rule that allows all traffic to/from the affected application server, bypassing inspection.
Answer: B
Explanation:
* Identify the Goal: Troubleshoot efficiently to determine if stateful inspection is causing intermittent connectivity issues.
* Option A Evaluation: Disabling stateful inspection globally removes all security checks, potentially restoring connectivity but disrupting the entire VCN's security. This is inefficient and risky.
* Option B Evaluation: Creating a bypass rule for the application server avoids inspection, which could confirm the issue but weakens security for that server. It's a workaround, not a diagnostic step, and requires policy changes during troubleshooting.
* Option C Evaluation: Reviewing firewall logs for denied traffic is targeted and non-disruptive. Logs show if stateful inspection is dropping packets (e.g., due to session timeouts or rule mismatches), directly identifying the cause without altering configurations.
* Option D Evaluation: Recreating the firewall is highly disruptive, time-consuming, and doesn't guarantee insight into the current issue. It's not a troubleshooting step.
* Conclusion: Option C is the most efficient, as it leverages logs for precise diagnosis without impacting operations.
Per Oracle's Network Firewall documentation:
* "Network Firewall logs provide detailed information about allowed and denied traffic, including source
/destination IPs, ports, and protocols. Use logs to troubleshoot connectivity issues by identifying dropped packets due to stateful inspection or rule mismatches."
* "Stateful inspection tracks connection states; misconfigurations can lead to dropped sessions."This confirms logs are the best tool for diagnosing stateful inspection issues. Reference:Network Firewall Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/NetworkFirewall/overview.htm).

NEW QUESTION # 33
In a complex multi-region OCI environment using DRGs for transitive routing, which method is most efficient for ensuring that route updates from on-premises networks are propagated to all connected VCNs?
  • A. Using a centralized DRG route table with route distribution enabled.
  • B. Implementing a Service Gateway to broadcast route updates.
  • C. Attaching each VCN to a separate DRG and configuring static routing between them.
  • D. Manually updating static routes in each VCN's route table.
Answer: A
Explanation:
* Objective:Efficiently propagate on-premises route updates to multiple VCNs.
* DRG Capabilities:Supports route distribution to attached VCNs.
* Analyze Options:
* A:Manual updates are inefficient and error-prone; unsuitable.
* B:Centralized DRG with route distribution automates propagation; efficient.
* C:Multiple DRGs add complexity and manual effort; inefficient.
* D:Service Gateway is for OCI services, not route updates; incorrect.
* Conclusion:Centralized DRG with route distribution is the most efficient method.
Route distribution in a DRG simplifies multi-region routing. The Oracle Networking Professional study guide notes, "Using a centralized DRG with route distribution enabled allows routes learned from on-premises networks to be automatically propagated to all attached VCNs, reducing management overhead" (OCI Networking Documentation, Section: DRG Route Distribution). This leverages OCI's automation capabilities.

NEW QUESTION # 34
You're automating the creation of multiple VCNs across different OCI regions using Cloud Shell scripting.
Which authentication method within Cloud Shell is best suited to programmatically authenticate with OCI, ensuring both security and scalability for this automation task?
  • A. Leverage Instance Principals in conjunction with a dynamic group that includes your Cloud Shell session.
  • B. Using Resource Manager stack with Terraform to provision network resources including cross-region configurations, leveraging OCI Vault to handle the sensitive credentials used in Terraform scripts.
  • C. Using the default Cloud Shell user and configuring the OCI CLI with API keys in a shell script.
  • D. Creating a dedicated IAM user for automation, generating API keys, storing the keys securely in Cloud Shell's persistent storage, and using them in the scripts.
Answer: A
Explanation:
* Requirements:Secure, scalable authentication for Cloud Shell scripting.
* Methods:
* API Keys:Manual, less secure if stored.
* Instance Principals:Credential-less, dynamic.
* Terraform with Vault:Secure but complex for scripting.
* Evaluate Options:
* A:API keys in script are insecure; not scalable.
* Bersistent storage risks exposure; less secure.
* C:Instance Principals use IAM, no credentials; best fit.
* D:Overkill for simple scripting, better for IaC; less suited.
* Conclusion:Instance Principals offer security and scalability.
Instance Principals simplify automation. The Oracle Networking Professional study guide states,"Instance Principals allow Cloud Shell to authenticate via dynamic groups without storing credentials, ideal for secure, scalable scripting" (OCI Networking Documentation, Section: Authentication in Cloud Shell). This avoids key management issues.

NEW QUESTION # 35
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. Audit Logs
  • C. Flow Logs
  • D. Service 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. Referenceoad Balancer Logging - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Balance/Tasks/managinglogs.htm).

NEW QUESTION # 36
Your company is setting up a FastConnect connection with a provider. You have purchased a port from the provider, and they are requesting information to set up the connection to Oracle Cloud Infrastructure. They specifically require information to configure the VLANs. What information regarding VLAN configuration is ESSENTIAL for them to successfully establish the FastConnect circuit?
  • A. A single unused VLAN ID, your BGP ASN, and the BGP peering IP addresses you want to use.
  • B. The MTU (Maximum Transmission Unit) size for all VNICs in your OCI tenancy.
  • C. The list of all VCN CIDR blocks and their associated tags.
  • D. Your Oracle Cloud Identifier (OCID) and compartment ID.
Answer: A
Explanation:
* Requirement: Provide VLAN config info for FastConnect setup.
* Option A: CIDR blocks are for routing, not VLAN setup-incorrect.
* Option B: VLAN ID defines the circuit, BGP ASN and peering IPs establish routing-essential and correct.
* Option C: MTU is a performance setting, not required for VLAN config-incorrect.
* Option D: OCID and compartment ID are for OCI management, not provider setup-incorrect.
* Conclusion: Option B provides the necessary VLAN configuration details.
Oracle states:
* "For FastConnect, provide the provider with a VLAN ID, your BGP ASN, and BGP peering IPs to configure the virtual circuit."This confirms Option B. Reference:FastConnect Configuration - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#providerconfig).
