Question 1

A financial services company is implementing a multicloud strategy, storing sensitive customer data in OCI due to its enhanced security features, running analytics workloads in AWS, and utilizing a SaaS application hosted in Google Cloud Platform (GCP). To comply with stringent data sovereignty regulations, the company requires that all traffic between OCI and AWS must transit exclusively within the United States. Which is the MOST critical consideration when choosing a connectivity solution to ensure compliance?

A. Leveraging public internet-based connectivity with geographically restricted DNS resolution to limit traffic outside the US

B. Using the native OCI Dynamic Routing Gateway (DRG) and AWS Virtual Private Gateway (VGW) with IPSec VPNs, as this automatically ensures traffic stays within the specified region

C. Using a generic VPN tunnel between OCI and AWS, ensuring both gateways are located within US regions

D. Selecting a FastConnect partner who can guarantee that all OCI-AWS traffic will stay within the United States geographic boundary

Question 2

Your company is migrating its legacy application to OCI. This application uses self-signed certificates. As part of the migration, you want to replace these with certificates issued by a trusted Certificate Authority (CA) managed through OCI Certificates. What is the most secure and recommended method to handle this transition?

A. Obtain certificates from OCI Certificates, gradually replace self-signed certificates on application servers, and update the truststores on client systems to include the OCI Certificates CA.

B. Configure OCI WAF to bypass certificate validation for the legacy application.

C. Immediately replace the self-signed certificates on all application servers with certificates issued by OCI Certificates, without any gradual rollout.

D. Import the self-signed certificates into OCI Certificates and continue using them until they expire.

Question 3

Consider a scenario where you have several private subnets within your VCN, and instances in these subnets need to access different OCI Object Storage buckets across various compartments. How can you efficiently manage and secure private access to Object Storage for all these subnets while adhering to the principle of least privilege?

A. Implement a Service Gateway within the VCN and utilize IAM policies and route tables to direct traffic to the appropriate Object Storage service endpoints.

B. Create a Private Endpoint for each Object Storage bucket within each private subnet.

C. Deploy a single NAT Gateway and manage access using Network Security Groups (NSGs) for each subnet.

D. Configure a single Internet Gateway and use IAM policies to control access at the bucket level.

Question 4

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. Evaluate using a third-party WAN optimization solution.

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

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

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

Question 5

You are tasked with setting up a secure connection from an OCI Compute instance running in a private subnet to a third-party API that is only accessible over the internet via a static public IP address. Your company policy prohibits exposing the compute instance directly to the internet. Which combination of VCN resources BEST facilitates this secure outbound connection to the third-party API?

A. A Dynamic Routing Gateway (DRG) connected to a FastConnect circuit, with routes configured to direct traffic to the third-party API's IP address.

B. A NAT Gateway and a security list allowing outbound traffic to the third-party API's IP address.

C. An Internet Gateway with a security list allowing outbound traffic to the third-party API's IP address.

D. A Service Gateway configured with a Service CIDR label that includes the third-party API's IP address.

Question 6

Your company is migrating its publicly accessible website to OCI. You want to ensure the highest level of security and prevent DNS spoofing or cache poisoning attacks. You've decided to implement DNSSEC.
Which of the following is the most important first step in enabling DNSSEC for your domain using OCI DNS?

A. Create a Traffic Management Steering Policy with the "DNSSEC" option enabled.

B. Generate a Key Signing Key (KSK) and a Zone Signing Key (ZSK) using a third-party tool and upload them to OCI DNS.

C. Enable DNSSEC on the OCI DNS zone for your domain and obtain the Delegation Signer (DS) record from OCI DNS.

D. Configure the OCI DNS resolver to validate all incoming DNS responses using DNSSEC.

Question 7

Your company has deployed a mission-critical application on OCI that requires consistent, predictable network performance. You have established a FastConnect circuit to connect your on-premises data center to OCI. You observe that the network latency varies throughout the day, and you suspect that other traffic is impacting the performance of your application. Which FastConnectfeature can you leverage to prioritize traffic for your mission-critical application and improve its network performance?

A. FastConnect Quality of Service (QoS)

B. FastConnect BGP Communities

C. FastConnect VLAN Tagging

D. FastConnect Jumbo Frames

Question 8

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?

A. No specific OCI endpoint is required. The on-premises SQL Server is accessed directly through the DRG and appropriate routing.

B. An Internet Gateway with a public endpoint on the SQL Server.

C. A Service Gateway configured to access the on-premises SQL Server.

D. A Private Endpoint within the VCN configured to connect to the private IP address of the on-premises SQL Server.
