Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q70-Q75):

NEW QUESTION # 70
Your company is deploying a high-throughput, low-latency financial application on OCI. This application relies on raw TCP connections and requires connection persistence to maintain session state. You anticipate extremely high traffic volume and need a load balancer that can handle millions of concurrent connections with minimal overhead. You also want to use private endpoints. Which OCI load balancing option provides the most appropriate solution to meet these stringent performance and security requirements?

A. Network Load Balancer with TCP load balancing and 5-Tuple Hash Persistence
B. Global Load Balancer with TCP load balancing and Cookie-based Persistence
C. Regional Load Balancer with TCP load balancing and IP Hash Persistence
D. Regional Load Balancer with HTTP load balancing and Source IP Hash Persistence

Answer: A

Explanation:
* Requirements:High throughput, low latency, TCP, persistence, private endpoints.
* Load Balancer Options:
* ALB:Layer 7, higher overhead, HTTP-focused.
* NLB:Layer 4, low overhead, TCP/UDP optimized.
* Global LB:Global routing, not regional focus.
* Evaluate Options:
* A:ALB with IP Hash has overhead; less optimal.
* B:NLB with 5-Tuple Hash offers low latency, persistence, private support; best fit.
* C:Global LB with cookies is HTTP-based; incorrect.
* D:HTTP focus is irrelevant for raw TCP; incorrect.
* Conclusion:NLB with 5-Tuple Hash meets all criteria.
NLB is ideal for high-performance TCP. The Oracle Networking Professional study guide states, "Network Load Balancer provides low-latency, high-throughput TCP load balancing with 5-Tuple Hash persistence, supporting private endpoints for secure, high-volume applications" (OCINetworking Documentation, Section:
Network Load Balancer). This aligns with financial app needs.

NEW QUESTION # 71
Which OCI logging feature allows you to correlate network traffic patterns from Flow Logs with application- level events from Service Logs for comprehensive troubleshooting?

A. Log Export
B. Log Groups
C. Log Streams
D. Log Analytics

Answer: D

Explanation:
* Objective: Correlate Flow Logs and Service Logs for troubleshooting.
* Option A: Log Groups organize logs but don't analyze correlations-incorrect.
* Option B: Log Analytics enables querying and visualizing logs from multiple sources, ideal for correlation-correct.
* Option C: Log Streams collect logs but don't correlate-incorrect.
* Option D: Log Export moves logs, not analyzes them-incorrect.
* Conclusion: Log Analytics is the best feature.
Oracle documentation confirms:
* "Log Analytics allows you to correlate and analyze logs from Flow Logs and Service Logs, providing insights for troubleshooting."This validates Option B. Reference:Log Analytics Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Logging/Concepts/loganalytics.htm).

NEW QUESTION # 72
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 dynamic routing with BGP.
B. Use a Service Gateway to connect to a third-party VPN service available on the internet.
C. 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.
D. Use a Dynamic Routing Gateway (DRG) with a Site-to-Site VPN connection configured using static routing.

Answer: D

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 # 73
In a hybrid cloud migration, which OCI component is essential for dynamically routing traffic between on- premises networks and OCI Virtual Cloud Networks (VCNs), facilitating seamless communication?

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

Answer: C

Explanation:
* Objective: Identify the OCI component for dynamic routing in a hybrid setup.
* Option A: Internet Gateway enables public internet access, not private hybrid routing-incorrect.
* Option B: DRG is a virtual router that dynamically routes traffic between on-premises networks and VCNs via FastConnect or VPN, using protocols like BGP-correct.
* Option C: Service Gateway provides private access to OCI services, not on-premises connectivity- incorrect.
* Option D: LPG peers VCNs within the same region, not with on-premises-incorrect.
* Conclusion: DRG is essential for hybrid dynamic routing.
Oracle documentation confirms:
* "The Dynamic Routing Gateway (DRG) enables dynamic routing between your on-premises network and VCNs, supporting hybrid cloud connectivity via FastConnect or VPN."This validates Option B.
Reference:Dynamic Routing Gateway Overview - Oracle Help Center(docs.oracle.com/en-us/iaas
/Content/Network/Tasks/managingDRGs.htm).

NEW QUESTION # 74
You have configured an IPSec VPN tunnel over your FastConnect circuit to OCI. You are experiencing intermittent connectivity issues and notice that the VPN tunnel is flapping (frequently going up and down).
You have verified the IKE and IPSec configuration and confirmed that the security policies are correct.
Which is a LESS likely cause of the VPN tunnel flapping when using IPSec over FastConnect, compared to using IPSec over the public internet?

A. MTU (Maximum Transmission Unit) misconfiguration leading to fragmentation.
B. BGP route flapping or instability.
C. Issues with network congestion or packet loss.
D. Mismatched pre-shared keys or incorrect IKE/IPSec parameters.

Answer: C

Explanation:
* Context: Tunnel flapping over FastConnect vs. public internet.
* Option A: Congestion/packet loss is less likely over FastConnect's dedicated link than the unpredictable public internet-correct.
* Option B: Mismatched keys/parameters would prevent tunnel establishment, not flapping-equally likely in both.
* Option C: MTU issues cause fragmentation in both scenarios-equally likely.
* Option D: BGP flapping is more relevant with FastConnect's dynamic routing-more likely here.
* Conclusion: Option A is less likely over FastConnect.
Oracle notes:
* "FastConnect provides a stable, dedicated connection, reducing congestion and packet loss compared to public internet VPNs."This supports Option A. Reference:IPSec over FastConnect - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/settingupIPSec.htm#fastconnect).
