Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q99-Q104):

NEW QUESTION # 99
You are designing a hybrid cloud solution where sensitive data must be transferred between your on-premises data center and an OCI VCN. You require a dedicated, private connection with guaranteed bandwidth and low latency. In addition to FastConnect, what additional product would you implement to achieve encryption of the traffic traversing the FastConnect link and to ensure data confidentiality?

A. OCI Bastion
B. MACsec
C. IPSec VPN
D. Oracle Cloud Infrastructure Vault

Answer: B

Explanation:
* Requirement Analysis: The solution needs a private, high-bandwidth, low-latency connection (provided by FastConnect) with encryption for data confidentiality.
* Option A (IPSec VPN): IPSec encrypts traffic at Layer 3 over public or private networks. While feasible over FastConnect, it's redundant since FastConnect is already private, adding unnecessary overhead and complexity.
* Option B (OCI Vault): Vault manages encryption keys and secrets but doesn't encrypt traffic itself- only supports application-level encryption, not link-level-incorrect.
* Option C (MACsec): MACsec (Media Access Control Security) provides Layer 2 encryption for Ethernet traffic, ideal for securing FastConnect's dedicated link directly between devices, ensuring confidentiality without higher-layer overhead-correct.
* Option D (OCI Bastion): Bastion secures remote access to VCN resources, not link encryption- incorrect.
* Conclusion: MACsec enhances FastConnect with efficient, link-level encryption, meeting all requirements.
Oracle documentation states:
* "MACsec provides Layer 2 encryption for FastConnect, securing Ethernet traffic between on-premises and OCI infrastructure. It's ideal for ensuring confidentiality over dedicated connections."This supports Option C as the best additional product. Reference:FastConnect Security Options - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#security).

NEW QUESTION # 100
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. Audit Logs
D. Flow 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 # 101
Consider a scenario where you have several private subnets within your VCN, and instances in these subnets need to access different OCI Object Storage buckets across various compartments. How can you efficiently manage and secure private access to Object Storage for all these subnets while adhering to the principle of least privilege?

A. Create a Private Endpoint for each Object Storage bucket within each private subnet.
B. Deploy a single NAT Gateway and manage access using Network Security Groups (NSGs) for each subnet.
C. Configure a single Internet Gateway and use IAM policies to control access at the bucket level.
D. Implement a Service Gateway within the VCN and utilize IAM policies and route tables to direct traffic to the appropriate Object Storage service endpoints.

Answer: D

Explanation:
* Goal: Private, secure, least-privilege access to Object Storage across subnets.
* Option A: Internet Gateway uses public access, violating privacy-incorrect.
* Option B: NAT Gateway is for internet, not OCI services-incorrect.
* Option C: Service Gateway provides private access; IAM policies enforce least privilege; route tables manage traffic-correct.
* Option D: Private Endpoints per bucket/subnet are inefficient and unscalable-incorrect.
* Conclusion: Option C is efficient and secure.
Oracle states:
* "A Service Gateway enables private access to Object Storage. Use IAM policies for least-privilege access and route tables for traffic control."This supports Option C. Reference:Service Gateway Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/servicegateway.
htm).

NEW QUESTION # 102
Your company is migrating its on-premises data center to OCI. A critical security requirement is to maintain centralized logging and auditing of all network traffic traversing the OCI Network Firewall. You need to ensure that every session that passes through the firewall is logged and can be analyzed for security events.
Which OCI service should you configure in conjunction with the Network Firewall to achieve this centralized logging?

A. OCI Logging Analytics.
B. OCI Cloud Guard.
C. OCI Audit Service.
D. OCI Service Connector Hub with OCI Logging.

Answer: D

Explanation:
* Requirement:Centralized logging of Network Firewall traffic for analysis.
* OCI Services:
* Audit Service:Logs API calls, not network traffic.
* Logging Analytics:Analyzes logs but needs log ingestion.
* Service Connector Hub with Logging:Moves firewall logs to OCI Logging.
* Cloud Guard:Monitors security posture, not detailed logging.
* Evaluate Options:
* A:Audit Service is for API events; incorrect.
* B:Logging Analytics requires log source; incomplete.
* C:Service Connector Hub with Logging captures and stores firewall logs; best fit.
* D:Cloud Guard is for threat detection, not logging; incorrect.
* Conclusion:Service Connector Hub with OCI Logging meets the requirement.
OCI Network Firewall logs require integration with OCI Logging. The Oracle Networking Professional study guide states, "Service Connector Hub can be configured to transfer Network Firewall logs to OCI Logging for centralized storage and analysis, meeting auditing requirements" (OCI Networking Documentation, Section:
Network Firewall Logging). This ensures every session is logged and auditable.

NEW QUESTION # 103
Your company has decided to migrate its on-premises data center to OCI. As a network engineer, you need to establish a secure and reliable connection between the on-premises network and the OCI VCN with the following constraints: high bandwidth requirements, low latency requirements, secure private connection, and redundant connectivity crucial for business continuity. Which is the MOST suitable and resilient solution, considering the VCN gateway options?

A. Multiple FastConnect circuits to a DRG in conjunction with multiple VPN Connect connections to the same DRG.
B. A single VPN Connect connection to a DRG.
C. Multiple VPN Connect connections to a DRG.
D. A FastConnect circuit with a DRG.

Answer: A

Explanation:
* Constraints: High bandwidth, low latency, secure private connection, redundancy.
* Option A: Single VPN Connect offers security but lacks high bandwidth, low latency, and redundancy-unsuitable for migration needs.
* Option B: Multiple VPNs improve redundancy but still rely on public internet, limiting bandwidth and latency performance compared to dedicated circuits.
* Option C: Single FastConnect provides high bandwidth, low latency, and privacy via a dedicated line, but lacks redundancy.
* Option D: Multiple FastConnect circuits ensure high bandwidth and low latency with redundancy.
Adding multiple VPNs as backup enhances resilience, meeting all constraints.
* Conclusion: Option D is the most suitable and resilient, balancing performance and continuity.
Oracle states:
* "FastConnect provides a private, high-bandwidth, low-latency connection to OCI. Use multiple circuits for redundancy."
* "Combine FastConnect with IPSec VPN for additional failover options."Option D aligns with this guidance. Reference:FastConnect Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content
/Network/Tasks/fastconnect.htm).
