Which technique does NOT help you get the optimal performance out of the Oracle Cloud Infrastructure (OCI) File Storage service? (Choose the best answer.)

• A. Right size compute instances from where file system is accessed based on their network capacity.
• B. Increase concurrency by using multiple threads, multiple clients, and multiple mount targets.
• C. Serialize operations to the file system to access consecutive blocks as much as possible.
• D. Limit access to the same Availability Domain (AD) as the File Storage service where possible.

When creating an alarm query in Oracle Cloud Infrastructure (OCI) Monitoring, which of the following statement is NOT valid?

• A. You must specify a Metric
• B. You must specify Statistic
• C. You must specify Resource Group
• D. You must specify an interval
• E. You must specify Trigger rule (threshold or absence).

A developer has created a file system in the Oracle CloudInfrastructure (OCI) File Storage service. She then launches an Oracle Linux compute instance and mounts the file system successfully on this instance. The next day, she tries writing to the file system from the compute instance using the following command: touch
/mnt/yourmountpoint/helloworld.txt But receives an error message: touch: cannot touch
'/mnt/yourmountpoint/helloworld.txt': Permission denied What might be the reason for this error?

• A. The touch command is not available in Oracle Linux, by default.
• B. User is not part of any OCI Identity and Access Management (IAM) group with write permissions to the File Storage service.
• C. User is connecting as the default Oracle Linux user opc instead of the root user.
• D. Service limits or quota for file system writes have been breached.

Which two statements about the Oracle Cloud Infrastructure (OCI) Command Line Inter-face (CLI) are TRUE? (Choose two.)

• A. The CLI provides the same core functionality as the Console, plus additional commands.
• B. The CLI provides an automatic way to connect with instances provisioned on OCI.
• C. The CLI allows you to use the Python language to interact with OCI APIs.
• D. You can filter CLI output using the JMESPath query option for JSON.
• E. You can run CLI commands from inside OCI Regions only.

You have created an Autonomous Data Warehouse (ADW) service in your company Oracle Cloud Infrastructure (OCI) tenancy and you now have to load historical data into it. You have already extracted this historical data from multiple data marts and data warehouses. This data is stored in multiple CSV text files and these files are ranging in size from 25 MB to 20 GB. Which is the most efficient and error tolerant method for loading data into ADW? (Choose the best answer.)

• A. Create Auth token, use it to create an object storage credential by executing DBMS_CLOUD.CREATE_CREDENTIAL, using OCI CLI upload the CSV files to an OCI object storage bucket, create the tables in the ADW database and then execute Data Pump Import for each CSV file to copy the contents into the corresponding ADW database table.
• B. Create the tables in the ADW database and then execute SQL*Loader for each CSV file to load the contents into the corresponding ADW database table.
• C. Create Auth token, use it to create an object storage credential by executing DBMS_CLOUD.CREATE_CREDENTIAL, using OCI CLI upload the CSV files to an OCI object storage bucket, create the tables in the ADW database and then execute DBMS_CLOUD.COPY_DATA for each CSV file to copy the contents into the corresponding ADW database table.
• D. Create Auth token, use it to create an object storage credential by executing DBMS_CLOUD.CREATE_CREDENTIAL, using the web console upload the CSV files to an OCI object storage bucket, create the tables in the ADW database and then execute DBMS_CLOUD.COPY_DATA for each CSV file to copy the contents into the corresponding ADW database table.
