Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q46-Q51):

NEW QUESTION # 46
Your organization uses a combination of OCI and AWS. Applications in OCI frequently access services hosted in AWS. You are experiencing slow and inconsistent data transfer speeds when transferring large files between the two clouds. You have a Site-to-Site VPN, but are considering other options. Which option is NOT a valid design consideration for improving the data transfer performance between OCI and AWS?

  • A. Evaluate the distance between the OCI and AWS regions you are using.
  • B. Evaluate using a third-party WAN optimization solution.
  • C. Deploy a dedicated interconnect through a network service provider that specializes in connecting OCI and AWS.
  • D. Determine the pricing scheme used for all OCI compute resources so you can predict when you need to scale bandwidth.

Answer: D

Explanation:
* Objective: Improve OCI-AWS data transfer performance.
* Option A: Region distance affects latency-valid.
* Option B: Dedicated interconnect boosts bandwidth and stability-valid.
* Option C: Compute pricing doesn't influence inter-cloud bandwidth-invalid.
* Option D: WAN optimization can enhance transfer efficiency-valid.
* Conclusion: Option C is not a design consideration for performance.
Oracle notes:
* "To optimize OCI-AWS connectivity, consider region proximity, dedicated interconnects, or WAN optimization. Compute pricing is unrelated to network performance."This excludes Option C.

/Concepts/hybridcloud.htm).


NEW QUESTION # 47
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. Network Load Balancer
  • B. Global Load Balancer with Traffic Management Steering Policies
  • C. Flexible Load Balancer
  • D. Regional Load Balancer

Answer: B

Explanation:
* 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.


NEW QUESTION # 48
Your security policy mandates that all communication between your compute instances in a private subnet and OCI Object Storage must be authenticated and authorized using IAM policies and not rely on public IP addresses. Which OCI networking feature is the most appropriate to satisfy this requirement?

  • A. Private Subnet with a NAT Gateway and IAM rules.
  • B. Private Subnet with a Service Gateway and IAM rules.
  • C. Public Subnet with an Internet Gateway and IAM rules.
  • D. Public Subnet with a Network Firewall and IAM rules.

Answer: B

Explanation:
* Requirement: Private, IAM-secured access to Object Storage.
* Option A: Public subnet with Internet Gateway uses public IPs-violates policy.
* Option B: NAT Gateway is for internet access, not private OCI services-incorrect.
* Option C: Service Gateway enables private access to Object Storage, paired with IAM for auth- correct.
* Option D: Public subnet with firewall still relies on public IPs-incorrect.
* Conclusion: Option C meets all requirements.
Oracle states:
* "Use a Service Gateway for private access to OCI Object Storage from a private subnet, with IAM policies for authentication and authorization."This supports Option C. Reference:Service Gateway Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/servicegateway.
htm).


NEW QUESTION # 49
You are designing a highly available web application in OCI. You've created a VCN with two public subnets across different Availability Domains (ADs). You need to enable IPv6 support for the application to cater to a growing number of IPv6-only clients. You plan to use a Load Balancer to distribute traffic to backend compute instances in the public subnets. Which of the following approaches ensures the highest level of resilience and IPv6 connectivity for your application?

  • A. Configure the VCN with a public IPv6 CIDR block obtained from Oracle. Configure the Load Balancer to listen on IPv4 only, while backend compute instances listen on both IPv4 and IPv6, relying on NAT for IPv6 clients.
  • B. Configure the VCN with a /48 IPv6 ULA prefix. Configure the Load Balancer to listen on IPv4 only, and the compute instances to listen on both IPv4 and IPv6, relying on NAT for IPv6 clients.
  • C. Configure the VCN with a public IPv6 CIDR block obtained from Oracle. Configure the Load Balancer to listen on both IPv4 and IPv6 addresses. Ensure the backend compute instances also listen on both IPv4 and IPv6 addresses.
  • D. Configure the VCN with a /48 IPv6 ULA prefix. Configure the Load Balancer to listen on both IPv4 and IPv6 addresses. Ensure the backend compute instances also listen on both IPv4 and IPv6 addresses.
    Route traffic accordingly using NSGs.

Answer: C


NEW QUESTION # 50
Which OCI service or feature enables the enforcement of granular, identity-based access controls for packet routing, crucial for implementing Zero Trust principles?

  • A. Internet Gateway
  • B. Network Security Groups (NSGs)
  • C. Dynamic Routing Gateway (DRG)
  • D. Service Gateway

Answer: B

Explanation:
* Zero Trust Principles:Require explicit, identity-based access controls at every network stage.
* Evaluate OCI Services:
* Internet Gateway:Enables public internet access, no identity-based control.
* Service Gateway:Provides private service access, no granular routing control.
* NSGs:Offer stateful, identity-based rules at the VNIC level.
* DRG:Facilitates routing, not identity-based access control.
* NSG Fit:NSGs allow rules based on VNIC identity, source/destination IP, and ports, aligning with Zero Trust.
* Conclusion:NSGs are the best fit for granular, identity-based routing control.
NSGs are pivotal for Zero Trust in OCI. The Oracle Networking Professional study guide states, "Network Security Groups provide granular, stateful security rules that can be applied to specific VNICs, enabling identity-based access controls essential for Zero Trust architectures" (OCI Networking Documentation, Section: Network Security Groups). Unlike security lists (subnet-level), NSGs offer instance-level precision.
