Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q114-Q119):

NEW QUESTION # 114
Which OCI component facilitates transitive routing between VCNs in different regions via a dedicated, private network backbone, while also enabling connectivity to on-premises networks?

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

Answer: C

Explanation:
* Requirement:Transitive routing across regions and to on-premises, privately.
* Components:
* LPG:Intra-region VCN peering; limited scope.
* DRG:Cross-region and on-premises routing via private backbone.
* Service Gateway:OCI service access; not transitive.
* Internet Gateway:Public internet; not private.
* Evaluate Options:
* A:Region-specific; incorrect.
* B:Supports multi-region and on-premises; correct.
* C:Service-focused; incorrect.
* D:Public; incorrect.
* Conclusion:DRG is the key component.
DRG enables complex routing scenarios. The Oracle Networking Professional study guide notes, "The Dynamic Routing Gateway (DRG) facilitates transitive routing between VCNs in different regions and on- premises networks over OCI's private backbone" (OCI Networking Documentation, Section: Dynamic Routing Gateway). This meets both requirements efficiently.

NEW QUESTION # 115
In a multi-tier application architecture with separate public and private subnets, where should an OCI Bastion host be placed to provide secure access to resources in the private subnets without exposing them to the internet?

A. In a separate VCN peered with the application VCN.
B. Behind an Internet Gateway in the public subnet.
C. In a dedicated public subnet specifically for Bastion hosts.
D. Directly in the private subnet.

Answer: C

Explanation:
* Purpose:Secure access to private subnet resources via Bastion.
* Placement Considerations:Must be internet-accessible yet isolated.
* Evaluate Options:
* A:Private subnet lacks internet access for Bastion; incorrect.
* B:Dedicated public subnet balances accessibility and isolation; correct.
* C:Separate VCN adds complexity, unnecessary; less optimal.
* D:Ambiguous phrasing, but implies exposure; less precise than B.
* Conclusion:Dedicated public subnet is the best placement.
OCI Bastion requires public access with security. The Oracle Networking Professional study guide notes,
"Place the Bastion host in a public subnet with a dedicated configuration to allow secure SSH access to private subnet resources without exposing them directly" (OCI Networking Documentation, Section: Bastion Host Placement). Option B ensures this balance.

NEW QUESTION # 116
You are designing a hybrid cloud environment where multiple VCNs in OCI need to communicate with your on-premises network. You are using a single Dynamic Routing Gateway (DRG) to connect to your on- premises network via FastConnect. You want to ensure that each VCN is isolated from the others and that traffic between VCNs must pass through your on-premises security appliances for inspection. How should you configure the DRG attachments and route tables to enforce this security policy?

A. Attach all VCNs and the FastConnect to the DRG. Configure the DRG route table associated with each VCN attachment to route all traffic destined for other VCNs to the FastConnect attachment. Configure the FastConnect DRG route table to route traffic destined to each VCN to the corresponding VCN attachment.
B. Attach all VCNs and the FastConnect to the DRG. Configure static routes on each VCN's route table pointing to the DRG for any subnet not within the VCN. Enable the "Transit Routing" feature on the DRG to allow inter-VCN communication.
C. Attach each VCN directly to the FastConnect using IPSec VPN tunnels, bypassing the DRG entirely to ensure all traffic flows through the on-premises security appliances.
D. Attach each VCN to the DRG using a Local Peering Gateway (LPG) and then attach one VCN to FastConnect. Configure routes so that traffic traverses from LPG to LPG through the on-premises network.

Answer: A

Explanation:
* Requirements:VCN isolation, inter-VCN traffic via on-premises appliances.
* DRG Role:Central hub for VCN and FastConnect connectivity.
* Evaluate Options:
* A:DRG routes inter-VCN traffic via FastConnect to on-premises; meets isolation and inspection needs.
* B:Transit Routing allows direct VCN-to-VCN communication, bypassing on-premises; incorrect.
* C:Bypassing DRG with VPNs is complex and unsupported; incorrect.
* D:LPG is for intra-region peering, not DRG-to-FastConnect; incorrect.
* Conclusion:Option A enforces the policy via DRG route tables.
DRG route tables control traffic flow. The Oracle Networking Professional study guide states, "To force inter- VCN traffic through an on-premises network via FastConnect, configure DRG route tables to route VCN- destined traffic to the FastConnect attachment, ensuring isolation and inspection" (OCI Networking Documentation, Section: DRG Routing). This setup leverages a single DRG effectively.

NEW QUESTION # 117
When migrating workloads from another cloud provider to OCI, what is a key consideration when choosing a connectivity strategy to ensure optimal network performance?

A. Only considering managed connectivity solutions to avoid the complexity of configuring VPNs or direct interconnects
B. Prioritizing the lowest possible initial setup cost, even if it results in higher ongoing operational expenses
C. Ignoring the geographical proximity of the cloud regions being interconnected
D. Factoring in the bandwidth requirements of the applications being migrated and choosing a connection that can accommodate peak traffic loads

Answer: D

Explanation:
* Goal: Ensure optimal performance in connectivity strategy.
* Option A: Low setup cost may compromise performance-incorrect.
* Option B: Proximity affects latency; ignoring it harms performance-incorrect.
* Option C: Matching bandwidth to app needs ensures performance-correct.
* Option D: Limiting to managed solutions restricts options-incorrect.
* Conclusion: Option C is the key consideration.
Oracle advises:
* "Consider application bandwidth requirements and peak loads when selecting a connectivity strategy for optimal performance during migration."This supports Option C. Reference:Network Planning for Migration - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/migration.
htm#planning).

NEW QUESTION # 118
Which OCI resource is used to establish private connectivity between two VCNs within the same region, facilitating direct, low-latency communication?

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

Answer: A

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.
