Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q95-Q100):

NEW QUESTION # 95
When troubleshooting inter-region connectivity issues between VCNs peered via a Dynamic Routing Gateway (DRG), which OCI tool is most effective for verifying the routing configuration and identifying potential misconfigurations?

A. Network Visualizer
B. Oracle Cloud Guard
C. OCI Audit Logs
D. DRG Route Tables

Answer: D

Explanation:
* Goal: Verify routing for inter-region VCN peering via DRG.
* Option A: Cloud Guard monitors security, not routing-incorrect.
* Option B: Audit Logs track changes, not current routing state-incorrect.
* Option C: DRG Route Tables define routing rules, directly showing misconfigurations-correct.
* Option D: Network Visualizer shows topology but not detailed routing rules-less effective.
* Conclusion: DRG Route Tables are most effective.
Oracle states:
* "DRG Route Tables are the primary tool for verifying and troubleshooting routing configurations for inter-region VCN peering."This validates Option C. Reference:DRG Troubleshooting - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/managingDRGs.htm#troubleshooting).

NEW QUESTION # 96
Your organization requires that all backups of critical application data stored in OCI Object Storage from an instance within a private subnet must remain within the Oracle Cloud Infrastructure network and not traverse the public internet. Which OCI networking component should you configure to enable this secure and private access to Object Storage?

A. NAT Gateway
B. Network Firewall
C. Internet Gateway
D. Service Gateway

Answer: D

Explanation:
* Requirement:Private access to Object Storage from a private subnet.
* Components:
* Internet Gateway:Public internet access; unsuitable.
* NAT Gateway:Outbound internet; unsuitable.
* Service Gateway:Private OCI service access; fits requirement.
* Network Firewall:Security, not routing; incorrect.
* Evaluate Options:
* A:Public internet; violates policy.
* B:Public internet; violates policy.
* C:Keeps traffic in OCI network; correct.
* D:Doesn't enable access; incorrect.
* Conclusion:Service Gateway ensures private access.
Service Gateway is designed for private OCI service access. The Oracle Networking Professional study guide explains, "A Service Gateway allows private subnet instances to access Object Storage without traversing the public internet, ensuring secure data transfer within OCI" (OCI Networking Documentation, Section: Service Gateway). This meets the security requirement.

NEW QUESTION # 97
Which OCI service or feature enables the enforcement of granular, identity-based access controls for packet routing, crucial for implementing Zero Trust principles?

A. Dynamic Routing Gateway (DRG)
B. Internet Gateway
C. Service Gateway
D. Network Security Groups (NSGs)

Answer: D

Explanation:
* Zero Trust Principles:Require explicit, identity-based access controls at every network stage.
* Evaluate OCI Services:
* Internet Gateway:Enables public internet access, no identity-based control.
* Service Gateway:Provides private service access, no granular routing control.
* NSGs:Offer stateful, identity-based rules at the VNIC level.
* DRG:Facilitates routing, not identity-based access control.
* NSG Fit:NSGs allow rules based on VNIC identity, source/destination IP, and ports, aligning with Zero Trust.
* Conclusion:NSGs are the best fit for granular, identity-based routing control.
NSGs are pivotal for Zero Trust in OCI. The Oracle Networking Professional study guide states, "Network Security Groups provide granular, stateful security rules that can be applied to specific VNICs, enabling identity-based access controls essential for Zero Trust architectures" (OCI Networking Documentation, Section: Network Security Groups). Unlike security lists (subnet-level), NSGs offer instance-level precision.

NEW QUESTION # 98
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. Attaching each VCN to a separate DRG and configuring static routing between them.
B. Manually updating static routes in each VCN's route table.
C. Implementing a Service Gateway to broadcast route updates.
D. Using a centralized DRG route table with route distribution enabled.

Answer: D

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 # 99
In the context of OCI's Zero Trust Packet Routing, which principle emphasizes the necessity of explicitly defining and enforcing access controls at every stage of network communication?

A. Implicit Trust
B. Least Privilege
C. Network Segmentation
D. Perimeter Security

Answer: B

Explanation:
* Zero Trust Context:Assumes no inherent trust, requiring explicit controls at all network stages.
* Evaluate Principles:
* Implicit Trust:Assumes trust, opposite of Zero Trust; incorrect.
* Least Privilege:Grants minimal access, explicitly enforced; aligns with Zero Trust.
* Perimeter Security:Relies on boundary protection, not Zero Trust; incorrect.
* Network Segmentation:Isolates networks, a tactic not a principle; incomplete.
* Conclusion:Least Privilege is the core principle for explicit access control.
Zero Trust Packet Routing in OCI emphasizes Least Privilege. The Oracle Networking Professional study guide states, "The Least Privilege principle in Zero Trust requires that access controls be explicitly defined and enforced at every network communication stage, ensuring no implicit trust" (OCI Networking Documentation, Section: Zero Trust Networking). This drives granular security policies.
