You deployed a database on a Standard Compute instance in Oracle Cloud Infrastructure (OCI) due to cost concerns. The database requires additional storage with high I/O and you decided to use OCI Block Volume service for it.
With this requirement in mind, which elastic performance option should you choose for the Block Volume?

  1. Balanced Performance
  2. Higher performance
  3. Extreme performance
  4. Lower cost

Answer(s): B

You have 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 so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should have read-only access to the file system.

What change would you make to satisfy this requirement?

  1. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
  2. Connect via SSH to one of the application servers where the file system has been mounted. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.
  3. 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.
  4. 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.

Answer(s): A

Explanation:

NFS export options enable you to create more granular access control than is possible using just security list rules to limit VCN access. You can use NFS export options to specify access levels for IP addresses or CIDR blocks connecting to file systems through exports in a mount target.



Your company uses the Oracle Cloud Infrastructure (OCI) Object Storage service to share large data sets with its data science team. The data science team consists of 20 people who work from offices in Washington, D.C., and Tokyo. While working in these offices, employees are assigned an IP address from the public IP range 129.146.31.0/27

Which two steps should you take to ensure that the Object Storage bucket used in this scenario was only accessible from these office locations? (Choose two.)

  1. Write an IAM policy that includes the conditional statement where request.networkSource.name
    =CorpNet
  2. Set the bucket visibility to public and only share the URL with the data science team via email
  3. Create a pre-authenticated request for each data set and only share with the data science team via email
  4. Create a Network Source named CorpNetwork with a CIDR block of 129.146.31.0/27
  5. Create a Network Source named CorpNetwork with a CIDR block of 129.146.0.0/16
  6. Write an IAM policy that includes the conditional statement where request.region = 129.146.31.0/27

Answer(s): C,E



Which statement Is true about Data Guard implementation in Oracle Cloud Infrastructure (OCI) bare metal and virtual machine database systems?

  1. Primary and standby databases must be in the same OCI region.
  2. Both database systems must be in the same compartment.
  3. Database systems need not be the same shape type (e.g, primary database can be a virtual machine, and standby database a bare metal shape, and vice versa).
  4. Primary and standby database versions and editions need not be Identical.

Answer(s): B
