Oracle 1z0-1072-23 : Oracle Cloud Infrastructure 2023 Architect Associate

You created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system, therefore you have provisioned one using the file storage service (FSS).
You have also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that the application servers can access FSS. The security team changed the settings for the DB System to have read-only access to the file system. However when they test it, they are unable to access FSS.
How would you allow access to FSS?

• A. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
• B. Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.
• C. Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.
• D. Change the ingress rules corresponding to the DB System subnet to be stateful.
• E. Modify the security list associated with the subnet where the mount target resides.

You plan to launch a VM instance with the VM.Standard2.24 shape and Oracle Linux 8 platform image. You want to protect your VM instance from low-level threats, such as rootkits and bootkits that can infect the firmware and operating system and are difficult to detect.
What should you do?

• A. Create a burstable instance.
• B. Create a shielded instance.
• C. Use in-transit encryption.
• D. Use Vulnerability Scanning Service.

When creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) with the VCN wizard, which THREE gateways are created automatically?

• A. Service Gateway
• B. Local Peering Gateway
• C. NAT Gateway
• D. Dynamic Routing Gateway
• E. Bastion Host
• F. Internet Gateway
• G. Storage Gateway

Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OI) File System snapshots?

• A. Snapshots are a consistent, point-in-time view of your file systems.
• B. Before you can clone a file system, at least one snapshot must exist for the file system.
• C. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
• D. Snapshots are accessible under the root directory of the file system at .snapshot/name.

You have a high-demand web application running on Oracle Cloud Infrastructure (OCI). Your tenancy administrator has set up a schedule-based autoscaling policy on instance pool with an initial size of 5 instances for the application.
Policy 1:
Target pool size:10 instances
Execution time:8:30 a.m. on every Monday through Friday, in every month, in every year Cron expression:0 30 8 ? * MON-FRI * Which statement accurately explains the goal of this policy?

• A. Goal: A recurring monthly schedule. On all days of the month, set the initial pool size to 5 instances. At
  8.30 a.m., on every day of the month, scale out to 10 instances.
• B. Goal: A recurring daily schedule. On weekday mornings at 8.30 a.m., scale out to 10 instances.
• C. Goal: A one-time schedule with only one scaling out event. At 8:30 a.m., on December 31, 2021, scale the instance pool to 10 instances from 5.
• D. Goal: A recurring weekly schedule. On all days of the week at 8.30 a.m., scale out the pool to 10 instances from the initial size of 5
