NEW QUESTION 71
Your organization is deploying a critical database application on OCI. To ensure high availability, you have deployed the database instances across multiple availability domains (ADs) within asingle region. You need to distribute client connections to the database instances and ensure that the load balancer can handle long- lived TCP connections with minimal overhead. Session persistence is not required. Which OCI load balancing solution would you choose in this scenario to minimize latency and connection establishment overhead?

NEW QUESTION 72
You are troubleshooting an issue where a compute instance in a private subnet within a VCN cannot reach OCI Object Storage. You have verified that a Service Gateway is configured for the VCN and that the route table associated with the subnet has a route rule directing traffic for OCI Services to the Service Gateway.
However, the instance still cannot connect. What is the MOST likely cause of the problem?

The instance requires a public IP address to access OCI Object Storage.

The security list or network security group associated with the subnet or instance is not configured to allow outbound traffic to the OCI Object Storage service CIDR block.

The Service Gateway is not configured to allow access to OCI Object Storage.

The instance is not configured with the Oracle Cloud Agent.

NEW QUESTION 73
You are using Terraform to deploy a multi-tier application architecture consisting of a public subnet hosting a load balancer, a private subnet hosting application servers, and another private subnet hosting a database. The Terraform code successfully creates all the required infrastructure, including route tables and security lists.
However, after deployment, you realize that the load balancer cannot reach the application servers in the private subnet. You have verified that the load balancer is healthy and the application servers are running.
What is the most likely cause of this connectivity problem?

The security list associated with the application server subnet does not allow ingress traffic from the load balancer’s IP address range.

The route table associated with the application server subnet has a default route pointing to the Internet Gateway, which is incorrect for a private subnet.

The Network Address Translation (NAT) Gateway is misconfigured, preventing the application servers from initiating connections back to the load balancer.

The load balancer’s security list is not configured to allow egress traffic to the application server subnet on the required ports (e.g., port 8080).

NEW QUESTION 74
You’re designing a multi-region deployment of your application on OCI. You want to use OCI’s global load balancing capabilities, but also require the WAF to protect against attacks close to the user. Which configuration provides the best balance between global load balancing and regional WAF protection?

Use OCI Global Load Balancer (GLB) with a single regional WAF protecting the backend servers in one region.

Use OCI GLB to distribute traffic to regional Load Balancers, each fronted by a regional WAF.

Configure the WAF in front of the OCI GLB itself to inspect all traffic globally.

Configure the OCI GLB to distribute traffic based on source IP address to specific regions, and enable WAF on the regional Load Balancer.

NEW QUESTION 75
You’re automating the creation of multiple VCNs across different OCI regions using Cloud Shell scripting.
Which authentication method within Cloud Shell is best suited to programmatically authenticate with OCI, ensuring both security and scalability for this automation task?

NEW QUESTION 76
You are troubleshooting an issue where legitimate users are occasionally blocked by your OCI WAF, which is configured in “Detection” mode. You need to identify the specific WAF rules that are triggering these false positives and adjust them without disrupting legitimate traffic. Which approach offers the most efficient way to diagnose and resolve this issue?

Analyze the OCI WAF logs in OCI Logging Analytics, focusing on the rule IDs associated with blocked requests. Then, move the specific rule to “log only”.

Disable all WAF rules and then gradually re-enable them one by one until the issue reappears.

Increase the sensitivity level of the entire WAF configuration.

Whitelist the IP addresses of the affected users.

NEW QUESTION 77
