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. Deploy a dedicated interconnect through a network service provider that specializes in connecting OCI and AWS.

B. Determine the pricing scheme used for all OCI compute resources so you can predict when you need to scale bandwidth.

C. Evaluate the distance between the OCI and AWS regions you are using.

D. Evaluate using a third-party WAN optimization solution.

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 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.

B. 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.

C. 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.

D. 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.

In a multi-tier application environment with geographically dispersed teams requiring access to private resources, how can an OCI Bastion service be optimized to reduce latency for remote users?

A. Implementing Bastion hosts in multiple regions closer to user locations.

B. Configuring a Bastion service with a public load balancer.

C. Using dynamic port forwarding to allow direct connections to private resources.

D. Deploying a single Bastion host in the primary application region.

出題：6

You have configured DNSSEC for your domain hosted on OCI DNS. You understand the importance of regularly rotating your Key Signing Key (KSK) to maintain security best practices. Which of the following statements regarding KSK rotation in OCI DNS is TRUE?

A. KSK rotation is a fully automated process managed by OCI DNS and requires no manual intervention.

B. KSK rotation is not supported in OCI DNS; you must migrate your DNS zone to another provider if you require KSK rotation.

C. KSK rotation in OCI DNS involves enabling a "KSK Rollover" feature, which automatically handles the key rotation process while minimizing disruption to DNS resolution.

D. You must manually generate a new KSK and ZSK pair and upload them to OCI DNS to initiate a KSK rotation.

出題：7

A development team has deployed a three-tier application in an OCI VCN. The application consists of a public-facing web tier, an application tier, and a database tier. The team reports that the web tier instances can communicate with the application tier instances, but the application tier instances cannot connect to the database tier instances. All security lists are configured to allow all traffic within the VCN. Which OCI Networking diagnostic tool would BEST help you quickly isolate the root cause of this connectivity issue?

A. OCI Bastion

B. VCN Flow Logs

C. Connection Diagnostics

D. Network Firewall

Your application running on OCI Compute instances in a private subnet requires high availability and the ability to distribute incoming traffic across multiple instances. You need to ensure that the load balancer can handle both HTTP and HTTPS traffic and provides health checks to monitor the availability of your backend servers. Which OCI Load Balancer offering is the most suitable for this scenario, considering both functionality and cost-effectiveness for a production environment?

A. Flexible Load Balancer with HTTP and HTTPS listeners and health checks.

B. Flexible Load Balancer with only TCP listeners.

C. Network Load Balancer (NLB) with UDP listeners.

D. Network Load Balancer (NLB) with TCP listeners.

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 /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.

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 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.

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 listener to point directly to the 'green' backend set.

B. 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.

C. 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.

D. Create a new listener that points to the 'green' backend set and delete the old listener.
