Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q86-Q91):

NEW QUESTION # 86
Your company has established a hybrid cloud environment using FastConnect to connect your on-premises network to your OCI VCN. You are advertising on-premises network prefixes to OCI via BGP. You want to ensure that OCI only learns routes from your on-premises network that are within a specific range, and that any other prefixes advertised are rejected to prevent routing conflicts. Which BGP attribute and configuration on the OCI side should you use to achieve this?

A. Route Filtering using Prefix Lists: Configure Prefix Lists on the FastConnect virtual circuit to accept only the desired prefix ranges and reject all others.
B. AS Path Prepending: Configure AS Path Prepending on the FastConnect virtual circuit to discourage OCI from selecting routes outside the desired range.
C. Route Filtering using Route Distinguisher (RD) and Route Target (RT): Configure RDs and RTs on the FastConnect virtual circuit to filter routes based on tenant isolation.
D. MED (Multi-Exit Discriminator): Configure MED values on the on-premises BGP router toinfluence OCI's route selection based on preferred exit points.

Answer: A

Explanation:
* Objective:Filter BGP routes on OCI to accept only specific on-premises prefixes.
* BGP Attributes Overview:
* AS Path Prepending:Lengthens AS path to influence route preference, not filtering.
* MED:Influences exit point selection, not route acceptance.
* RD/RT:Used in MPLS VPNs for tenant isolation, not simple prefix filtering.
* Prefix Lists:Directly filter prefixes based on IP ranges.
* Evaluate Options:
* A:AS Path Prepending affects preference, not filtering; unsuitable.
* B:MED influences path selection, not route rejection; incorrect.
* C:RD/RT is for VPN contexts, not applicable here.
* D:Prefix Lists explicitly allow/deny prefixes, meeting the requirement.
* Conclusion:Prefix Lists on the FastConnect virtual circuit provide precise control over accepted routes.
Prefix Lists are the most effective BGP tool for filtering routes in OCI. The Oracle Networking Professional study guide notes, "Prefix Lists can be applied to FastConnect virtual circuits to filter BGP advertisements, ensuring only approved prefixes are learned by OCI" (OCI Networking Documentation, Section: FastConnect and BGP). This prevents routing conflicts by rejecting unwanted prefixes, aligning with the security and control requirements.

NEW QUESTION # 87
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. Managed Bastion sessions with detailed session logging enabled.
B. Dynamic port forwarding sessions with no logging enabled.
C. Using a jump server with manually configured logging.
D. SSH port forwarding sessions with minimal audit logs.

Answer: A

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 # 88
You have successfully enabled DNSSEC on your OCI DNS zone and provided the DS record to your domain registrar. However, when you test your DNS configuration using online DNSSEC validation tools, you are still seeing errors indicating that DNSSEC validation is failing. What is the most likely reason for this failure?

A. The DNSSEC algorithm used by OCI DNS is not supported by the validation tools.
B. The Time To Live (TTL) value for your DNS records is too low, causing validation errors.
C. The OCI DNS resolver is not configured to validate DNSSEC signatures.
D. The domain registrar has not yet published the DS record in the parent zone, preventing the chain of trust from being established.

Answer: D

Explanation:
* Problem:DNSSEC validation fails post-setup.
* DNSSEC Chain:Requires DS record in parent zone for trust.
* Evaluate Causes:
* A:Low TTL affects caching, not validation; unlikely.
* B:Missing DS in parent zone breaks chain; most likely.
* C:Resolver config is client-side, not affecting external tools; incorrect.
* D:OCI uses standard algorithms; highly unlikely.
* Conclusion:Registrar delay in publishing DS is the primary cause.
DNSSEC relies on the parent zone. The Oracle Networking Professional study guide explains, "DNSSEC validation fails if the registrar hasn't published the DS record in the parent zone, as this breaks the chain of trust" (OCI Networking Documentation, Section: DNSSEC Troubleshooting). This is a common post- enablement issue.

NEW QUESTION # 89
For a migration scenario where on-premises workloads need to access OCI Object Storage for large data transfers, and a dedicated, private connection is required, which OCI service best fulfills this need?

A. Dynamic Routing Gateway (DRG) with Internet Gateway
B. Service Gateway via Site-to-Site VPN
C. Internet Gateway with public IP addressing
D. FastConnect Private Peering with a Service Gateway

Answer: D

Explanation:
* Needs: Private, dedicated connection for large data transfers to Object Storage.
* Option A: VPN with Service Gateway uses public internet, limiting bandwidth-incorrect.
* Option B: Internet Gateway exposes traffic publicly-incorrect.
* Option C: FastConnect Private Peering provides a dedicated link, and Service Gateway ensures private Object Storage access-correct.
* Option D: DRG with Internet Gateway isn't private-incorrect.
* Conclusion: Option C best meets the need.
Oracle states:
* "FastConnect Private Peering combined with a Service Gateway enables secure, high-bandwidth access to Object Storage from on-premises networks."This supports Option C. Reference:FastConnect and Service Gateway - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.
htm#servicegateway).

NEW QUESTION # 90
You are designing a multicloud architecture where your customer wants to leverage OCI for its cost-effective compute and storage, while utilizing Microsoft Azure's AI/ML services and AWS's extensive serverless capabilities. The application requires low latency and high bandwidth between the clouds. Which of the following approaches provides the LEAST optimal solution for interconnecting these three cloud providers for production workloads?

A. Connecting OCI to Azure via OCI Azure Interconnect, then establishing an IPSec VPN tunnel from Azure to AWS using Azure's VPN Gateway
B. Creating IPSec VPN tunnels between OCI, Azure, and AWS, utilizing the native VPN gateways offered by each respective cloud provider for secure, encrypted communication
C. Establishing a dedicated, low-latency connection between each cloud provider's nearest peering location using a third-party network provider for maximum bandwidth and minimizing network hops
D. Utilizing OCI FastConnect to establish private peering with Azure and AWS through supported FastConnect partners to ensure dedicated bandwidth and consistent performance

Answer: B

Explanation:
* Requirements: Low latency, high bandwidth for multicloud production.
* Option A: Dedicated peering via third-party provider offers high performance-optimal.
* Option B: IPSec VPNs over public internet have variable latency and limited bandwidth-least optimal.
* Option C: FastConnect peering with partners ensures dedicated performance-optimal.
* Option D: OCI-Azure Interconnect is fast, but VPN to AWS adds latency-less optimal than A or C but better than B.
* Conclusion: Option B is the least optimal due to performance constraints.
Oracle notes:
* "IPSec VPNs over public internet provide security but lack the bandwidth and latency consistency of dedicated connections like FastConnect for production workloads."This supports Option B as least optimal. Reference:Multicloud Connectivity Options - Oracle Help Center(docs.oracle.com/en-us/iaas
/Content/Network/Concepts/multicloud.htm#options).
