You are the Solutions Architect of a large company and are tasked with migrating all your services to Oracle Cloud Infrastructure. As part of this, you first design a Virtual Cloud Network (VCN) with a public subnet and a private subnet. Then in order to provide Internet connectivity to the instances in your private subnet, you create an Oracle Linux instance in your public subnet and configure NAT on it. However, even after adding all related security list rules and routes in the Route Table, your private subnet instances still cannot connect to the Internet.
Which action should you perform to enable Internet connectivity?

• A.Disable "Source and Destination Check" on the VNIC of your Linux instance.
• B.There is no way that a private subnet can connect to the Internet.
• C.Create a Dynamic Routing Gateway (DRG) and route your private IP traffic to the DRG.
• D.Restart the NAT instance.

You have two line of business operations (LOB1, LOB2) leveraging Oracle Cloud Infrastructure. LOB1 is deployed in VCN1 in the OCI US East region, while LOB2 is deployed in VCN2 in the US West region. You need to peer VCN1 and VCN2 for disaster recovery and data backup purposes. To ensure you can utilize the OCI Virtual Cloud Network remote peering feature, which CIDR ranges should be used?

• A.VCN1 (10.0.0.0/16) and VCN2 (10.0.1.0/24)
• B.VCN1 (10.0.0.0/16) and VCN2 (172.16.0.0/16)
• C.VCN1 (172.16.1.0/24) and VCN2 (172.16.1.0/27)
• D.VCN1 (192.168.0.0/16) and VCN2 (192.168.1.0/27)

You are an administrator with an application running in Oracle Cloud Infrastructure (OCI). The company has a fleet of OCI compute virtual instances behind an load balancer. The load balancer backend set health check API is providing a 'Critical' level warning. You have confirmed that your application Is running healthy on the backend servers. What Is the possible reason for this 'Critical' warning?

• A.The load balancer listener is not configured correctly.
• B.A user does not have correct Identity and Access Management (IAM) credentials on the backend servers.
• C.The security list associated with the subnet In which the backend server is provisioned does not include the IP range for the source of the health check requests.
• D.The route table associated with the subnet in which the backend server is provisioned does not include the route for the OCI load balancer.

You have an external facing web server running in the Oracle Cloud Infrastructure (OCI) London region. You are notified that customers in North America and Australia are facing high latency while connecting to your web server.
Which services are available on OCI that can help you get current latency statistics to your web server from these markets?

• A.Use DNS Zone Management service to check latency over that connection
• B.Setup an IPsec VPN with customers in those markets and check latency over that connection
• C.Use the Internet Intelligence tool. Run tests using the web server's public IP address and review traceroute details from different vantage points
• D.Setup a FastConnect with customers in those markets and check latency over that connection

You are designing a shared storage solution for your company in Oracle Cloud Infrastructure. The proposed storage solution should allow users to create a hierarchical structure (similar to the directory structure in Linux or Windows based systems). The solution should provide data encryption and a large amount of storage space.
Which would be the best implementation strategy?

• A.Use object storage. Create multiple namespaces with one bucket each. Make the buckets publicly accessible.
• B.Use file storage service. Create a file system and a mount target. Share the private IP of the mount target.
• C.Use block storage. Create and attach a large block storage volume to one compute instance. Assign a public IP to the compute instance. Store data on the block storage and access it by connecting to the compute instance.
• D.Use object storage. Create a single namespace and multiple buckets to create the hierarchical directory structure.
