NEW QUESTION # 22
You have created an Autonomous Data Warehouse (ADW) service in your company's 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 DBMS_CLOUD.COPY_DATA 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. CreateAuth 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 foreach CSV file to copy the contents into the corresponding ADW database table.
- D. Create Auth token, useit 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.
Answer: A
Explanation:
Explanation
Using Object Storage and COPY_DATA is the standard recommended method for fetching data into ADW.
Furthermore using CLI over web has the benefit of multipart upload, that is chunk upload of large files, thus reducing the chance of a transfer failure
NEW QUESTION # 23
You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSH connections to your Compute Instances that are deployed in a private subnet. The Compute Instances have an attached Network Security Group with a Source Type: Network Security Group (NSG), Source NSG:
NSG-050504. To secure the bastion host, you added the following ingress rules to its Network Security Group:

What is the root cause of this issue? (Choose the best answer.)
- A. The port 22 provides unrestricted access to 140.19.2.140 and to other IP address.
- B. A netmask of /32 allows all IP address in the 140.19.2.0 network, other thanyour IP 140.19.2.140
- C. Allcompute instances associated with NSG-050504 are also able to connect to the bastion host.
- D. The Security List allows access to all IP address which overrides the Network Security Group ingress rules.

NEW QUESTION # 38
A developer has created a file system in Oracle Cloud Infrastructure (OCI) File Storage service. She launches an Oracle Linux compute instance and successfully mounts the file system from the instance.
She then tries writing to the file system from the compute instance using the following command:
touch /mnt/yourmountpoint/helloworld
But gets an error message:
touch: cannot touch'/mnt/yourmountpoint/helloworrld': Permission denied Which is a reason for this error? (Choose the best answer.)
- A. Useris not part of any OCI Identity and Access Management group with write permissions to File Storage service.
- B. 'touch' command is not available in Oracle Linux by default.
- C. User is connecting as the default Oracle Linux user 'opc' instead of 'root' user.
- D. Service limits or quota for file system writes have been breached.
Answer: C
Explanation:
Explanation
https://docs.oracle.com/en-us/iaas/Content/File/Troubleshooting/cannotwrite.htm When a file system is created, the root user owns the root directory. If you're connecting from an instance that uses a Linux orCentOS platform image, the default user is opc. The default user is ubuntu when you connect from an instance that uses an Ubuntu platform image. These default users are not root users, so you can't initially write a file or directory to a new file system with these users.
