質問 1

You are tasked with migrating a critical, latency-sensitive application from Azure to OCI. Due to compliance requirements, all data must be encrypted in transit. Which connectivity option provides the BEST combination of security and performance for this migration?

（A）Utilize Azure ExpressRoute and OCI FastConnect through a colocation provider, then implement application-level encryption using TLS

（B）Configure a Site-to-Site VPN between Azure's Virtual Network Gateway and OCI's Dynamic Routing Gateway (DRG), relying on the built-in IPSec encryption

（C）Leverage Azure Data Factory to transfer data to OCI Object Storage via HTTPS

（D）Employ Azure VPN Gateway in conjunction with an OCI Load Balancer with SSL termination for the incoming connections from Azure

質問 2

You have successfully enabled DNSSEC on your OCI DNS zone and provided the DS record to your domain registrar. However, when you test your DNS configuration using online DNSSEC validation tools, you are still seeing errors indicating that DNSSEC validation is failing. What is the most likely reason for this failure?

（A）The Time To Live (TTL) value for your DNS records is too low, causing validation errors.

（B）The DNSSEC algorithm used by OCI DNS is not supported by the validation tools.

（C）The domain registrar has not yet published the DS record in the parent zone, preventing the chain of trust from being established.

（D）The OCI DNS resolver is not configured to validate DNSSEC signatures.

質問 3

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 IPv4 only, and the compute instances to listen on both IPv4 and IPv6, relying on NAT for IPv6 clients.

（B）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.

（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.

質問 4

A company wants to leverage a best-of-breed approach for their application stack. They plan to use OCI for its Autonomous Database, Azure for its container orchestration (AKS), and AWS for its object storage (S3).
Considering cost optimization and minimizing data egress charges, which strategy is the MOST efficient for transferring large datasets between these services?

（A）Establishing a hub-and-spoke model, using a central cloud provider as the data transfer hub, incurring egress charges from each cloud to the hub and then ingress charges from the hub to the destination cloud

（B）Using Storage Gateway service on each cloud and replicate data from one gateway to the other

（C）Utilizing a third-party data integration platform that is strategically located at a network peering point between OCI, Azure, and AWS

（D）Moving data directly between OCI Autonomous Database, Azure AKS, and AWS S3 using public internet, as this is the most cost-effective option

質問 5

You are managing a Site-to-Site VPN connection between your on-premises network and OCI. You notice that the VPN tunnel is frequently dropping and re-establishing. You have verified the internet connectivity at both ends and confirmed that the IKE (Internet Key Exchange) parameters are correctly configured. Which of the following is the most likely cause of the intermittent VPN tunnel disconnections?

（A）The OCI Dynamic Routing Gateway (DRG) is experiencing a temporary outage.

（B）The on-premises firewall is configured with incorrect NAT-Traversal settings.

（C）There is a misconfiguration in the security rules, blocking the IKE or ESP (Encapsulating Security Payload) traffic.

（D）The on-premises Customer-Premises Equipment (CPE) is configured with an incorrect public IP address.

質問 6

You are designing a hybrid cloud solution where sensitive data must be transferred between your on-premises data center and an OCI VCN. You require a dedicated, private connection with guaranteed bandwidth and low latency. In addition to FastConnect, what additional product would you implement to achieve encryption of the traffic traversing the FastConnect link and to ensure data confidentiality?

（A）Oracle Cloud Infrastructure Vault

（B）MACsec

（C）IPSec VPN

（D）OCI Bastion

質問 7

When establishing cross-tenancy connectivity using Remote Peering Connections (RPCs), which IAM policy statement is essential to grant the requesting tenancy the ability to initiate the connection?

（A）Allow group <group_name> to use remote-peering-connections in tenancy=<target_tenancy_OCID>

（B）Allow group <group_name> to read remote-peering-connections in tenancy=<target_tenancy_OCID>

（C）Allow group <group_name> to inspect virtual-network-family in tenancy=<target_tenancy_OCID>

（D）Allow group <group_name> to manage virtual-network-family in tenancy=<target_tenancy_OCID>

質問 8

Your company needs to connect an on-premises data center to an OCI Virtual Cloud Network (VCN) to extend their existing infrastructure to the cloud. The connection MUST be secure, reliable, and provide consistent, low-latency access to resources in both environments. Resources in the OCI VCN need access to the on-premises servers, and resources in the on-premises data center need to access the compute instances located in a private subnet within the OCI VCN. Which is the MOST appropriate architectural design for establishing connectivity in this hybrid cloud environment, considering the available endpoints and gateway options in OCI?

（A）Implement a Site-to-Site VPN connection between the on-premises network and the OCI VCN, utilizing a Dynamic Routing Gateway (DRG) in OCI.

（B）Establish a FastConnect connection between the on-premises network and the OCI VCN, utilizing a Dynamic Routing Gateway (DRG) in OCI.

（C）Configure a public endpoint for each resource in the OCI VCN that needs to be accessed from the on- premises network.

（D）Implement a FastConnect connection from the on-premises network to the OCI VCN utilizing a Dynamic Routing Gateway (DRG) in OCI and implement a Site-to-Site VPN connection as backup.
