Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q104-Q109):

NEW QUESTION # 104
For a multi-tier architecture with a strict compliance requirement to log all user access to private resources, which Bastion service configuration is most suitable?

A. Dynamic port forwarding sessions with no logging enabled.
B. SSH port forwarding sessions with minimal audit logs.
C. Using a jump server with manually configured logging.
D. Managed Bastion sessions with detailed session logging enabled.

Answer: D

Explanation:
* Requirement Analysis: Strict compliance mandates logging all user access to private resources in a multi-tier setup.
* Option A Assessment: Dynamic port forwarding with no logging fails compliance, as it provides no audit trail.
* Option B Assessment: Managed Bastion sessions in OCI offer detailed logging (e.g., session start/end times, user IDs), integrated with OCI Logging. This meets compliance needs with a managed, scalable solution.
* Option C Assessment: SSH port forwarding with minimal logs doesn't provide the detailed auditing required for strict compliance.
* Option D Assessment: A jump server with manual logging is error-prone, lacks scalability, and isn't a managed OCI service, making it less suitable.
* Conclusion: Option B provides the most robust, compliance-ready solution with detailed logging.
From Oracle's Bastion documentation:
* "OCI Bastion provides managed SSH sessions with detailed logging capabilities, capturing user access details for audit and compliance. Enable session logging to record all activities."This supports Option B as the best choice. Reference:Bastion Service Overview - Oracle Help Center(docs.oracle.com/en-us
/iaas/Content/Bastion/Concepts/bastionoverview.htm).

NEW QUESTION # 105
You are designing an OCI networking architecture for a multi-tier application using Infrastructure as Code (IaC). The architecture includes an OKE cluster for the front-end, a set of Compute instances for the back- end, and an Autonomous Database. You want to ensure that all traffic between these components is encrypted. You are using Transport Layer Security (TLS) for end-to-end encryption but are concerned about the overhead of encrypting all traffic within the VCN. Which approach provides the MOST balanced approach to security and performance, minimizing the overhead of encryption while still protecting sensitive data?

A. Use Network Security Groups (NSGs) and Security Lists to control access between components but do not implement any additional encryption within the VCN.
B. Implement mutual TLS (mTLS) for all traffic between the OKE cluster, the Compute instances, and the Autonomous Database.
C. Implement TLS encryption for traffic between the OKE cluster and the Compute instances and use Oracle Database Vault to encrypt data at rest and in transit for the Autonomous Database.
D. Implement TLS encryption only between the OKE cluster and the load balancer. Rely on the inherent security of the OCI network for traffic within the VCN.

Answer: C

Explanation:
* Goal: Balance security and performance with encryption in a VCN.
* Option A: TLS only to the load balancer leaves internal traffic unencrypted, risking exposure- insufficient security.
* Option B: mTLS everywhere maximizes security but adds significant overhead (e.g., certificate management), impacting performance-overkill.
* Option C: NSGs/Security Lists control access but don't encrypt traffic-lacks protection for sensitive data.
* Option D: TLS between OKE and Compute secures app-tier communication. Oracle Database Vault ensures ADB traffic is encrypted efficiently, leveraging built-in features-balanced approach.
* Conclusion: Option D optimizes security and performance.
Oracle states:
* "Use TLS for application traffic between tiers. Autonomous Database with Database Vaultprovides encryption in transit and at rest, minimizing overhead."This supports Option D. Reference:Security in OCI Networking - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts
/securityoverview.htm).

NEW QUESTION # 106
Which OCI resource is used to establish private connectivity between two VCNs within the same region, facilitating direct, low-latency communication?

A. Internet Gateway
B. Local Peering Gateway (LPG)
C. Dynamic Routing Gateway (DRG)
D. Service Gateway

Answer: B

Explanation:
* Objective: Identify the OCI resource for private, low-latency VCN-to-VCN connectivity in the same region.
* Option A: DRG connects VCNs to external networks (e.g., on-premises) or across regions, not for same-region peering-incorrect.
* Option B: LPG is designed for private peering of VCNs within the same region, ensuring low-latency communication-correct.
* Option C: Internet Gateway provides public internet access, not private connectivity-incorrect.
* Option D: Service Gateway connects VCNs to OCI services, not other VCNs-incorrect.
* Conclusion: Option B is the appropriate resource.
Oracle documentation states:
* "A Local Peering Gateway (LPG) enables private connectivity between two VCNs in the same region, providing direct, low-latency communication."This confirms Option B. Reference:Local VCN Peering Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/localVCNpeering.
htm).

NEW QUESTION # 107
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 in OCI DNS involves enabling a "KSK Rollover" feature, which automatically handles the key rotation process while minimizing disruption to DNS resolution.
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 is not supported in OCI DNS; you must migrate your DNS zone to another provider if you require KSK rotation.
D. KSK rotation is a fully automated process managed by OCI DNS and requires no manual intervention.

Answer: A

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).

NEW QUESTION # 108
In a Zero Trust network architecture, what is the primary purpose of implementing micro-segmentation within OCI VCNs?

A. To simplify inter-region connectivity.
B. To reduce the number of required route tables.
C. To limit the blast radius of potential security breaches.
D. To increase network bandwidth.

Answer: C

Explanation:
* Context: Zero Trust assumes no trust, requiring strict isolation (micro-segmentation).
* Option A: Bandwidth isn't increased by segmentation-incorrect.
* Option B: Segmentation may increase route tables for granularity, not reduce them-incorrect.
* Option C: Micro-segmentation isolates workloads, limiting breach impact (blast radius)-core Zero Trust goal and correct.
* Option D: Inter-region connectivity isn't simplified by micro-segmentation-incorrect.
* Conclusion: Option C aligns with Zero Trust principles.
Oracle notes:
* "Micro-segmentation in OCI VCNs, using NSGs and security lists, limits the blast radius of breaches by isolating resources, a key Zero Trust principle."This supports Option C. Reference:Zero Trust in OCI - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/zerotrust.htm).
