Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q100-Q105):

NEW QUESTION # 100
Which aspect of OCI's security framework is essential for continuous monitoring and verification of packet flows, a core requirement of Zero Trust Packet Routing?

A. Flow logs and audit trails
B. Default security lists
C. Static routing configurations
D. Public IP address assignments

Answer: A

Explanation:
* Goal: Support Zero Trust with packet flow monitoring.
* Option A: Static routing defines paths, not monitoring-incorrect.
* Option B: Security lists control access, not monitor-incorrect.
* Option C: Flow logs track traffic; audit trails log actions-essential for Zero Trust-correct.
* Option D: Public IPs enable access, not monitoring-incorrect.
* Conclusion: Option C is essential.
Oracle states:
* "Flow logs and audit trails provide continuous monitoring and verification of packet flows, critical for Zero Trust Packet Routing."This supports Option C. Reference:Zero Trust in OCI - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Concepts/zerotrust.htm).

NEW QUESTION # 101
Your company needs to establish a secure connection between your on-premises network and OCI for a pilot project. The project has a limited budget and requires a quick setup, but also demands that the connection is encrypted. The long-term plan involves migrating to FastConnect, but that will take several months. Which OCI VPN solution would be most suitable for this short-term, budget-conscious, and security-aware scenario?

A. Use a Dynamic Routing Gateway (DRG) with a Site-to-Site VPN connection configured using static routing.
B. Use a Service Gateway to connect to a third-party VPN service available on the internet.
C. Use a Dynamic Routing Gateway (DRG) with a Site-to-Site VPN connection configured using dynamic routing with BGP.
D. Deploy a third-party virtual appliance VPN solution from the OCI Marketplace within a public subnet and configure a VPN connection to your on-premises network.

Answer: A

Explanation:
* Requirements:Quick, cheap, encrypted VPN; interim before FastConnect.
* VPN Options:
* Static VPN:Simple, native, low cost.
* Third-Party Appliance:Complex, costly.
* Service Gateway:Not for VPN; incorrect.
* BGP VPN:Dynamic, more setup; less quick.
* Evaluate Options:
* A:Static VPN is fast, secure, budget-friendly; correct.
* B:Appliance adds cost and complexity; incorrect.
* C:Misaligned use of Service Gateway; incorrect.
* D:BGP is overkill for pilot; less efficient.
* Conclusion:Static VPN via DRG is most suitable.
Static VPN is ideal for quick setups. The Oracle Networking Professional study guide notes, "A Site-to-Site VPN with static routing via DRG provides a fast, encrypted connection for short-term needs, minimizing cost and setup time" (OCI Networking Documentation, Section: Site-to-Site VPN). This fits the pilot project perfectly.

NEW QUESTION # 102
You have deployed a distributed application across OCI and Azure. You have established the OCI-Azure Interconnect. You are experiencing packet loss and performance degradation when transmitting large volumes of data between the two cloud providers. You have verified that the network devices on both sides are correctly configured. Which is NOT a typical root cause to investigate when troubleshooting performance issues across the OCI-Azure Interconnect?

A. Review the pricing tiers in OCI to ensure that the current OCI Compute usage has not exceeded maximum bandwidth limits.
B. Evaluate Network Security Groups (NSGs) and Security Lists on both OCI and Azure to verify that traffic is allowed between the necessary subnets and ports.
C. Assess the MTU (Maximum Transmission Unit) size settings on both OCI and Azure VNICs to ensure that fragmentation is not occurring.
D. Inspect routing tables on both OCI and Azure to confirm that routes are correctly configured to direct traffic across the interconnect.

Answer: A

Explanation:
* Problem:Packet loss and degradation over OCI-Azure Interconnect.
* Typical Causes:Security rules, routing, MTU mismatches.
* Evaluate Options:
* A:NSGs/Security Lists blocking traffic is a common issue; typical.
* B:Routing misconfiguration can drop packets; typical.
* C:Pricing tiers affect billing, not interconnect bandwidth; not typical.
* D:MTU mismatches cause fragmentation and loss; typical.
* Conclusion:Pricing tiers are unrelated to interconnect performance issues.
Interconnect performance issues stem from network configuration, not pricing. The Oracle Networking Professional study guide states, "Troubleshooting multi-cloud interconnects involves checking security rules, routing, and MTU settings, as these directly impact traffic flow" (OCI Networking Documentation, Section:
Multi-Cloud Connectivity). Pricing tiers influence resource limits, not interconnect bandwidth.

NEW QUESTION # 103
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 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.
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 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.
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: C

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 # 104
In a multi-region OCI environment, which configuration is necessary to allow communication between two VCNs located in different regions through a DRG?

A. Attaching a Service Gateway to each VCN and enabling transitive routing.
B. Configuring Internet Gateways on each VCN and using public IP addresses for communication.
C. Attaching each VCN to the same DRG and configuring the appropriate route tables on the DRG.
D. Attaching an LPG to each VCN and configuring route tables to peer them directly.

Answer: C

Explanation:
* Requirement: Private communication between VCNs in different OCI regions via DRG.
* Option A: LPGs are for same-region VCN peering, not cross-region-incorrect.
* Option B: Service Gateways are for OCI service access, not VCN-to-VCN routing-incorrect.
* Option C: Attaching both VCNs to a single DRG (via Remote Peering Connections implicitly) and configuring route tables enables cross-region communication over OCI's backbone. This is the standard approach.
* Option D: Internet Gateways use public IPs, which is insecure and not private-incorrect.
* Conclusion: Option C is the necessary configuration for DRG-based cross-region connectivity.
Oracle documentation confirms:
* "To connect VCNs in different regions, attach each to a DRG using Remote Peering Connections (RPCs). Configure DRG route tables to route traffic between VCN CIDRs."Option C reflects this setup (RPCs are implied). Reference:VCN Peering Overview - Oracle Help Center(docs.oracle.com/en-us/iaas
/Content/Network/Tasks/remoteVCNpeering.htm).
