You are a network architect and have designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators requests to have access to OCI object storage service.
How can you meet this requirement?

A. Create a service gateway, add a new route rule to the private subnet route table that uses storage as your service gateway target type

B. Add a new route rule to the private subnet route table to route default traffic to the internet gateway

C. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway

D. Create a dynamic routing gateway (DRG) and attach it your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG

出題：4

You had an outage in your application caused by the loss of a shared volume provisioned by File Storage Service (FSS). At this point, you need to restore the data from a snapshot you created of the FSS.
What are the steps to restore the data?

A. Open OCI Console, select File Storage Service, find the snapshot you created and click restore.

B. Open OCI Console, select File Storage Service, find the shared storage, then click on snapshot and restore.

C. Access the directory where the shared volume is mounted, then cd into .snapshot folder, find the snapshot folder you want to recover and use cp or rsync tool to copy the files to the original location.

D. Access the directory, where you mounted the shared volume, then cd into .snapshot folder and find the snapshot folder you want to recover and rename that folder to the original folder name.

出題：5

You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard 1.2 compute without any block storage attached to it. Which two options allow you to increase disk performance? (Choose two.)

A. Terminate the compute instance and create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.

B. Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.

C. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.

D. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.

出題：6

Your application front end consists of several Oracle Cloud Infrastructure compute instances behind a load balancer. You have configured the load balancer to perform health checks on these instances. If an instance fails to pass the configured health checks, what will happen?

A. The instance is taken out of the back end set by the load balancer.

B. The instance is terminated automatically by the load balancer.

C. The instance is replaced automatically by the load balancer.

D. The load balancer stops sending traffic to that instance.

出題：7

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 file storage service. Create a file system and a mount target. Share the private IP of the mount target.

B. Use object storage. Create a single namespace and multiple buckets to create the hierarchical directory structure.

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 multiple namespaces with one bucket each. Make the buckets publicly accessible.

出題：8

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 route table associated with the subnet in which the backend server is provisioned does not include the route for the OCI load balancer.

B. A user does not have correct Identity and Access Management (IAM) credentials on the backend servers.

C. The load balancer listener is not configured correctly.

D. 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.

You have created a new compartment called Production to host some production apps. You have also created users in your tenancy and added them to a Group called "production group". Your users are still unable to access the Production compartment. How can you resolve this situation?

A. Write an IAM Policy for "production_group" granting it access to the production compartment

B. Your users get automatic access to all compartments, so no further action is needed

C. Write an IAM Policy for each specific user granting them access to the production compartment

D. Every compartment you create comes with a predefined set of policies, so no further action is needed

When terminating a compute instance, you want to preserve the boot volume and its data.

B. Disable the default option to delete the boot volume when terminating an instance.

C. Before terminating the instance, you must detach the boot volume.

D. Reboot the instance first, and then terminate the instance.
