QUESTION 63
Which OCI service facilitates the creation of a private connection between two VCNs located in different tenancies, without traversing the public internet?

QUESTION 64
Your company is migrating several applications to OCI and requires a highly available and resilient VPN connection between your on-premises network and OCI. You need to ensure that if one VPN tunnel fails, traffic automatically fails over to a backup tunnel with minimal disruption. Which configuration would BEST achieve high availability and automatic failover for your OCI Site-to-Site VPN connection?

QUESTION 65
When migrating workloads from AWS to OCI, which connectivity option generally offers the LOWEST latency and HIGHEST bandwidth for data transfer, assuming a direct, dedicated connection is financially viable?

QUESTION 66
When setting up cross-tenancy VCN peering using Local Peering Gateways (LPGs), which IAM permission is required in the target tenancy to accept the peering request?

QUESTION 67
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?

QUESTION 68
In a complex multi-region OCI environment using DRGs for transitive routing, which method is most efficient for ensuring that route updates from on-premises networks are propagated to all connected VCNs?

QUESTION 69
You are deploying a three-tier web application using Infrastructure as Code (IaC) and Oracle Kubernetes Engine (OKE) within a single VCN. The application consists of a public-facing web tier (running in OKE), an application tier, and a database tier. You want to ensure that only the web tier can access the application tier, and only the application tier can access the database tier. You are leveraging Network Security Groups (NSGs) for granular access control. Your IaC code successfully creates all the components, but you are experiencing connectivity issues. Specifically, Pods in the web tier cannot reach the application tier.
Reviewing your IaC configuration, you realize the NSG assignments for the OKE cluster’s node pool are misconfigured. Which of the following NSG configuration errors would most likely cause this connectivity issue?

QUESTION 70
You are managing a critical application hosted on OCI. To enhance security, you have enabled DNSSEC for your domain using OCI DNS. You want to automate the process of monitoring the health and validity of your DNSSEC configuration and receive alerts if any issues are detected. Which OCI service can be MOST effectively used for this DNSSEC monitoring purpose?

QUESTION 71
You have deployed an application on OCI that uses a Regional Load Balancer with an HTTPS listener. You want to enforce end-to-end encryption and ensure that the connection between the load balancer and the backend servers is also encrypted. Which load balancer configuration step is MANDATORY to achieve this?

QUESTION 72
Your organization is migrating workloads to a multicloud environment using OCI, AWS, and Azure. You have applications that require access to on-premises resources and must maintain high security standards.
Which connectivity configuration would provide the MOST secure and reliable access while adhering to best practices for a hybrid multicloud architecture?

QUESTION 73
You have configured an IPSec VPN tunnel over your FastConnect circuit to OCI. You are experiencing intermittent connectivity issues and notice that the VPN tunnel is flapping (frequently going up and down).
You have verified the IKE and IPSec configuration and confirmed that the security policies are correct.
Which is a LESS likely cause of the VPN tunnel flapping when using IPSec over FastConnect, compared to using IPSec over the public internet?

QUESTION 74
You are automating the deployment of a highly available OKE cluster across multiple availability domains (ADs) using Terraform. The OKE cluster needs to communicate with a database service running on a Compute instance in a separate private subnet within the same VCN. During the Terraform deployment, you encounter an error indicating that the Kubernetes pods cannot resolve the private IP address of the database instance. You’ve verified that DNS resolution works correctly for other resources within the VCN. What is the MOST probable reason for this DNS resolutionfailure?

QUESTION 75
In a multi-tier application architecture with separate public and private subnets, where should an OCI Bastion host be placed to provide secure access to resources in the private subnets without exposing them to the internet?

QUESTION 76
Which OCI service or feature enables the enforcement of granular, identity-based access controls for packet routing, crucial for implementing Zero Trust principles?

QUESTION 77
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?

QUESTION 78
You are designing an OCI VCN for a new application with the following requirements: The application servers in a private subnet must be able to download software updates from public repositories on the internet; the application servers must NOT be directly accessible from the public internet; the application servers must also be able to access Oracle Cloud Infrastructure Registry (OCIR) within the same region to pull container images. Which combination of VCN Gateways BEST meets these requirements?

QUESTION 79
You are a Network Engineer designing a hybrid cloud architecture for a large enterprise. The company requires secure and private connectivity between their on-premises network and their OCI VCN. They have sensitive data that cannot traverse the public internet. Which OCI VCN gateway is most appropriate for establishing this connection, ensuring end-to-end data encryption and isolation from the public internet?

QUESTION 80
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?

QUESTION 81
Your company is migrating an on-premises application to OCI. The application requires direct, low-latency access to an on-premises Microsoft SQL Server database. You’ve established a FastConnect connection between your on-premises network and an OCI VCN via a Dynamic Routing Gateway(DRG). You want to access this database from the OCI VCN. Which type of endpoint, in conjunction with appropriate routing, should you use to facilitate this connection?

QUESTION 82
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?
