Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q35-Q40):

NEW QUESTION # 35
You are managing a critical application hosted on OCI. To enhance security, you have enabled DNSSEC for your domain using OCI DNS. You want to automate the process of monitoring the health and validity of your DNSSEC configuration and receive alerts if any issues are detected. Which OCI service can be MOST effectively used for this DNSSEC monitoring purpose?

A. OCI Audit Service.
B. OCI Logging Analytics.
C. OCI Vulnerability Scanning Service.
D. OCI Monitoring Service.

Answer: D

Explanation:
* Goal: Automate DNSSEC health monitoring with alerts.
* Option A: Vulnerability Scanning is for compute instances, not DNSSEC-incorrect.
* Option B: Monitoring Service tracks metrics and logs, supports custom DNSSEC metrics, and provides alarms-correct.
* Option C: Audit Service logs API calls, not DNSSEC health-incorrect.
* Option D: Logging Analytics analyzes logs but lacks direct alerting-less effective than Monitoring.
* Conclusion: Option B is the most effective for automated monitoring and alerts.
Oracle documentation notes:
* "OCI Monitoring Service allows you to monitor metrics and logs, including DNSSEC-related data, and set alarms for proactive notifications."This supports Option B. Reference:Monitoring Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Monitoring/Concepts/monitoringoverview.
htm).

NEW QUESTION # 36
You are designing a multi-tier application within an OCI Virtual Cloud Network (VCN). The application comprises a public-facing web tier in one subnet, an application tier in another, and a database tier in a third.
For security reasons, you want to ensure that only the application tier can initiate connections to the database tier. The web tier needs to be able to communicate with the application tier, but not directly with the database tier. You are using private IP addresses within your VCN. Which procedural step is MOST effective to achieve this network isolation?

A. Create separate security lists for each subnet and configure ingress and egress rules to restrict traffic accordingly. Configure the route table for the Web Tier subnet to route traffic destined for the Database Tier subnet through the Application Tier.
B. Create separate security lists for each subnet and configure ingress and egress rules to restrict traffic accordingly. Create appropriate route rules in each subnet's route table.
C. Create a single Network Security Group (NSG) and associate it with all three subnets. Configure ingress and egress rules within the single NSG to restrict traffic accordingly.
D. Create separate Network Security Groups (NSGs) for each tier and configure ingress and egress rules to restrict traffic accordingly. Configure the route table for the Web Tier subnet to route traffic destined for the Database Tier subnet through the Application Tier.

Answer: B

Explanation:
* Requirements: App tier only initiates to DB; web tier to app tier only.
* Option A: NSGs with forced routing through app tier adds complexity and latency-less effective.
* Option B: Single NSG lacks subnet-level isolation-incorrect.
* Option C: Separate security lists per subnet with ingress/egress rules enforce isolation; route tables ensure proper VCN routing-correct and effective.
* Option D: Security lists are good, but routing web-to-DB via app tier is unnecessary-incorrect.
* Conclusion: Option C achieves isolation efficiently.
Oracle states:
* "Use separate security lists per subnet with ingress/egress rules to isolate tiers. Route tables manage intra-VCN traffic without forced hops."This supports Option C. Reference:Security Lists Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/securitylists.htm).

NEW QUESTION # 37
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. Deploy a single NAT Gateway and manage access using Network Security Groups (NSGs) for each subnet.
B. Implement a Service Gateway within the VCN and utilize IAM policies and route tables to direct traffic to the appropriate Object Storage service endpoints.
C. Configure a single Internet Gateway and use IAM policies to control access at the bucket level.
D. Create a Private Endpoint for each Object Storage bucket within each private subnet.

Answer: B

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 # 38
You are a cloud architect designing a multi-tiered application on OCI. One tier consists of publicly accessible web servers that must be protected from common web exploits. You plan to use OCI Network Firewall to achieve this. You need to configure the Network Firewall to detect and prevent SQL injection attacks against the web servers. Which Network Firewall feature is most suitable for this purpose?

A. Geo-location filtering to block traffic from countries known for SQL injection attacks.
B. Intrusion Detection and Prevention System (IDPS) signatures with custom rule sets for SQL injection.
C. Stateful Inspection, configured with default IPS policies.
D. URL Filtering with predefined categories blocking SQL injection attempts.

Answer: B

Explanation:
* Goal:Protect web servers from SQL injection using Network Firewall.
* Firewall Features:
* Stateful Inspection:Basic traffic tracking, limited exploit detection.
* IDPS:Detects and prevents exploits via signatures.
* URL Filtering:Blocks URLs, not payload-based attacks.
* Geo-location:Blocks regions, not specific threats.
* Evaluate Options:
* A:Default IPS lacks SQL injection specificity; insufficient.
* B:IDPS with custom signatures targets SQL injection; most suitable.
* C:URL Filtering doesn't address SQL injection payloads; incorrect.
* D:Geo-location is broad, not precise; ineffective.
* Conclusion:IDPS with custom rules is the best feature.
IDPS in OCI Network Firewall is designed for exploit prevention. The Oracle Networking Professional study guide explains, "The Intrusion Detection and Prevention System (IDPS) uses signatures to detect and block specific threats like SQL injection, with custom rule sets for tailored protection" (OCI Networking Documentation, Section: Network Firewall IDPS). This ensures precise defense against web exploits.

NEW QUESTION # 39
You have configured DNSSEC for your domain hosted on OCI DNS. You understand the importance of regularly rotating your Key Signing Key (KSK) to maintain security best practices. Which of the following statements regarding KSK rotation in OCI DNS is TRUE?

A. KSK rotation is a fully automated process managed by OCI DNS and requires no manual intervention.
B. You must manually generate a new KSK and ZSK pair and upload them to OCI DNS to initiate a KSK rotation.
C. KSK rotation in OCI DNS involves enabling a "KSK Rollover" feature, which automatically handles the key rotation process while minimizing disruption to DNS resolution.
D. KSK rotation is not supported in OCI DNS; you must migrate your DNS zone to another provider if you require KSK rotation.

Answer: C

Explanation:
* Objective: Identify the true statement about KSK rotation in OCI DNS.
* Option A: OCI DNS automates much of the process but requires user initiation, not fully automated- incorrect.
* Option B: OCI DNS generates keys internally; manual generation and upload aren't required- incorrect.
* Option C: OCI DNS offers a "KSK Rollover" feature that, once enabled, automates the rotation process, ensuring minimal disruption-correct.
* Option D: KSK rotation is supported via the rollover feature-incorrect.
* Conclusion: Option C accurately describes OCI DNS KSK rotation.
Oracle documentation confirms:
* "OCI DNS supports KSK rotation through the KSK Rollover feature. Enable it to automatically rotate keys while maintaining DNS resolution continuity."This validates Option C. Reference:DNSSEC in OCI DNS - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/DNS/Tasks/managingdnssec.htm).
