問題 #89
You are designing a backup solution in OCI. Compute instances in a private subnet need to back up data to OCI Object Storage. Security policy mandates that data transfer must not traverse the public internet. You need to choose the most secure and cost-effective method for accessing Object Storage. Which endpoint
/gateway configuration should you implement?

A. Configure a Service Gateway with the Oracle Services Network service CIDR label for your region, and use regional Object Storage endpoints.
B. Configure a NAT Gateway and use public Object Storage endpoints with HTTPS enabled.
C. Configure a Dynamic Routing Gateway (DRG) and FastConnect to a remote region and use public Object Storage endpoints.
D. Configure an Internet Gateway and use public Object Storage endpoints.

答案：A

解題說明：
* Requirement Analysis:The solution must ensure private access to Object Storage without public internet traversal, while being cost-effective.
* Evaluate OCI Components:
* Internet Gateway:Provides public internet access, unsuitable for private connectivity.
* NAT Gateway:Allows outbound internet access from private subnets, but traffic still exits OCI.
* Service Gateway:Enables private access to OCI services like Object Storage within the same region.
* DRG with FastConnect:Used for on-premises connectivity, not intra-OCI service access.
* Option Assessment:
* A:Uses public internet, violating the security policy.
* B:HTTPS encrypts data, but traffic traverses the internet via NAT, violating the policy.
* C:Service Gateway keeps traffic within OCI's private network, meeting security and cost goals.
* D:Overly complex and costly, with public endpoints contradicting the requirement.
* Conclusion:Service Gateway with regional Object Storage endpoints ensures private, secure, and cost- effective access.
The Service Gateway is designed for private access to OCI services like Object Storage, avoiding the public internet. The Oracle Networking Professional study guide states, "A Service Gateway allows instances in a private subnet to access supported OCI services without an Internet Gateway or NAT Gateway, ensuring traffic remains within the Oracle network" (OCI Networking Documentation, Section: Service Gateway).
Using the Oracle Services Network service CIDR label for the region ensures compatibility with Object Storage endpoints, optimizing cost and security.

問題 #90
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

答案：B

解題說明：
* 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.

問題 #91
When migrating workloads requiring high availability and redundancy for on-premises connectivity to OCI, which approach is recommended?

A. Site-to-Site VPN over a single internet connection
B. Internet Gateway with multiple public IPs
C. Single FastConnect connection
D. Dual FastConnect connections with diverse paths

答案：D

解題說明：
* Requirements: HA and redundancy for on-premises-to-OCI connectivity.
* Option A: Single FastConnect lacks redundancy-incorrect.
* Option B: Single VPN over internet has no redundancy and poor performance-incorrect.
* Option C: Dual FastConnect with diverse paths ensures HA and redundancy via separate routes- correct.
* Option D: Internet Gateway with public IPs isn't dedicated or redundant-incorrect.
* Conclusion: Option C is the recommended approach.
Oracle advises:
* "For high availability, use dual FastConnect connections with diverse paths to eliminate single points of failure in hybrid connectivity."This supports Option C. Reference:FastConnect High Availability - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#ha).

問題 #92
You are designing a microservices-based application on OCI. Each microservice is deployed as a container in Oracle Container Engine for Kubernetes (OKE). You want to expose these microservices through a single entry point using a Layer 7 load balancer and route traffic based on the request path. Which OCI load balancing integration method with OKE is the MOST appropriate and efficient?

A. Manually create a Regional Load Balancer and configure backend sets with the private IP addresses of the Kubernetes worker nodes hosting the microservices.
B. Deploy a Kubernetes NodePort service for each microservice and configure an OCI NetworkLoad Balancer to forward traffic to the NodePort services on the worker nodes.
C. Deploy a Kubernetes Ingress controller that leverages an OCI Regional Load Balancer to route traffic to the microservice pods based on Ingress rules.
D. Deploy a Kubernetes LoadBalancer service, which automatically provisions an OCI Regional Load Balancer to distribute traffic to the microservice pods.

答案：C

解題說明：
* Goal: Layer 7 routing for OKE microservices via a single entry point.
* Option A: Manual configuration is inefficient and doesn't support path-based routing-incorrect.
* Option B: LoadBalancer service provisions a Layer 4 balancer, not Layer 7 path routing-incorrect.
* Option C: NodePort with NLB is Layer 4, less secure, and lacks path routing-incorrect.
* Option D: Ingress controller with Regional Load Balancer (Application LB) provides Layer 7 routing based on paths-correct and efficient.
* Conclusion: Option D is the best integration method.
Oracle states:
* "Use a Kubernetes Ingress controller with OCI Regional Load Balancer for Layer 7 routing to OKE microservices based on request paths."This supports Option D. Reference:OKE Networking - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengnetworking.htm).

問題 #93
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. Public IP address assignments
D. Static routing configurations

答案：A

解題說明：
* 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).
