Oracle Cloud Infrastructure 2025 Networking Professional 認定 1z0-1124-25 試験問題 (Q42-Q47):

質問 # 42
You are designing a highly available web application on OCI. The application needs to be accessible globally with traffic being routed to the nearest region based on user location. Additionally, you need to implement sophisticated traffic management policies, such as A/B testing and weighted traffic distribution based on application version. You also require protection against DDoS attacks. Which OCI load balancing solution is best suited for these requirements?

• A. Regional Load Balancer
• B. Network Load Balancer
• C. Flexible Load Balancer
• D. Global Load Balancer with Traffic Management Steering Policies

正解：D

解説：
* Requirements:Global access, geo-routing, advanced traffic management, DDoS protection.
* Load Balancer Options:
* Regional LB:Single-region, no global routing or advanced policies.
* NLB:Layer 4, no HTTP-based traffic management or DDoS features.
* Global LB with Steering Policies:Layer 7, supports geo-routing and policies.
* Flexible LB:Not a specific OCI service.
* Assess Fit:
* A:Lacks global and advanced features; unsuitable.
* B:No Layer 7 or DDoS protection; incorrect.
* C:Meets all requirements with geo-routing, steering policies, and WAF integration; best fit.
* D:Non-existent service; incorrect.
* Conclusion:Global LB with steering policies is the best solution.
The Global Load Balancer with Traffic Management Steering Policies supports global applications. The Oracle Networking Professional study guide explains, "Global Load Balancer enables geo-based routing and advanced traffic policies like A/B testing and weighted distribution, integrating with OCI WAF for DDoS protection" (OCI Networking Documentation, Section: Load Balancing - Traffic Management). This aligns with all specified requirements.

 

質問 # 43
You are responsible for maintaining the network connectivity between OCI and Azure using the OCI-Azure Interconnect. You need to perform planned maintenance on your on-premises network, which will temporarily disrupt the BGP (Border Gateway Protocol) sessions between your on-premises network and both OCI and Azure. You want to ensure that traffic between OCI and Azure continues to flow without interruption during the maintenance window. Which action is MOST important to take before starting the maintenance to ensure continuous connectivity between OCI and Azure?

• A. Configure static routes in OCI and Azure to directly route traffic between the VCNs/VNets without relying on BGP.
• B. Increase the BGP keepalive timers on both OCI and Azure to prevent the sessions from timing out.
• C. Notify Oracle and Microsoft support teams about the planned maintenance window.
• D. Disable the BGP sessions on both OCI and Azure before starting the maintenance.

正解：A

解説：
* Goal: Ensure OCI-Azure traffic during BGP disruption.
* Option A: Static routes bypass BGP dependency, maintaining connectivity-correct.
* Option B: Disabling BGP stops routing-incorrect.
* Option C: Notification doesn't ensure connectivity-incorrect.
* Option D: Keepalive timers delay detection, not prevent disruption-incorrect.
* Conclusion: Option A is most critical.
Oracle notes:
* "For uninterrupted OCI-Azure Interconnect traffic during BGP maintenance, configure static routes between VCNs and VNets."This supports Option A. Reference:OCI-Azure Interconnect - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/ociazureinterconnect.htm).

 

質問 # 44
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. 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.
• B. Review the pricing tiers in OCI to ensure that the current OCI Compute usage has not exceeded maximum bandwidth limits.
• C. Inspect routing tables on both OCI and Azure to confirm that routes are correctly configured to direct traffic across the interconnect.
• D. Assess the MTU (Maximum Transmission Unit) size settings on both OCI and Azure VNICs to ensure that fragmentation is not occurring.

正解：B

解説：
* 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.

 

質問 # 45
You are using the OCI Application Load Balancer (ALB) for your web application. You want to implement a blue/green deployment strategy to minimize downtime during application updates. You have two backend sets: 'blue' (the current version) and 'green' (the new version). What is the most efficient way to switch traffic from the 'blue' backend set to the 'green' backend set using the ALB's traffic management capabilities?

• A. Update the health check policy of the 'blue' backend set to mark all servers as unhealthy, forcing the ALB to send traffic to the 'green' backend set.
• B. Create a new listener that points to the 'green' backend set and delete the old listener.
• C. Update the listener to point directly to the 'green' backend set.
• D. Use the ALB's routing rules to gradually shift traffic from the 'blue' backend set to the 'green' backend set based on a percentage weight.

正解：D

解説：
* Goal:Minimize downtime in blue/green deployment with ALB.
* ALB Capabilities:Supports weighted routing for gradual traffic shifts.
* Evaluate Options:
* A:Immediate switch risks downtime if 'green' fails; less efficient.
* B:Listener swap causes abrupt change; not optimal.
* C:Gradual shift with weights ensures smooth transition; most efficient.
* D:Forcing 'blue' unhealthy is disruptive and hacky; inefficient.
* Conclusion:Weighted routing provides the smoothest transition.
ALB supports blue/green via routing rules. The Oracle Networking Professional study guide states,
"Application Load Balancer's routing rules allow weighted traffic distribution between backend sets, enabling blue/green deployments with minimal downtime" (OCI Networking Documentation,Section: Load Balancer Routing). This method ensures stability during updates.

 

質問 # 46
When using Service Connector Hub to route VCN Flow Logs to Object Storage for long-term analysis, which Service Connector Hub task type is essential for ensuring the logs are correctly processed and stored?

• A. Deliver Logs
• B. Ingest Logs
• C. Process Logs
• D. Transform Logs

正解：A

解説：
* Objective: Identify the essential Service Connector Hub task for routing Flow Logs to Object Storage.
* Option A (Ingest Logs): Ingesting is for bringing external logs into OCI, but Flow Logs are already OCI-native-incorrect.
* Option B (Process Logs): "Process Logs" isn't a specific task type in Service Connector Hub- incorrect.
* Option C (Deliver Logs): Deliver Logs moves logs to a target (e.g., Object Storage), ensuring storage-correct and essential.
* Option D (Transform Logs): Transforming modifies logs optionally, but delivery is required for storage-incorrect as the primary task.
* Conclusion: Deliver Logs is the essential task type for this scenario.
Oracle documentation states:
* "The Deliver Logs task in Service Connector Hub moves logs, such as VCN Flow Logs, to a specified destination like Object Storage for storage and analysis."This supports Option C. Reference:Service Connector Hub Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content
/ServiceConnectorHub/Concepts/serviceconnectorhub.htm).
