You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSHconnections to your Compute instances that are deployed private subnet. The Compute instances have an attached Network Security Group with a Source Type: Network security Group (NSG) , Source NSG:
-050504. To secure the bastion host, you added the following ingress rules to its Network Security Group:

However, after checking the bastion host logs, you discovered that there are IP addresses other than your own that can access your bastion host.
What is the root cause of this issue?

• A.A netmask of /32 allows all IP address in the 140.19.2.0 network, other than your IP 110.19.2.140
• B.The port 22 provides unrestricted access to 140.19.2.140 and to other IP address
• C.Al compute 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.

Recently your e-commerce web application has been receiving significantly more traffic than usual. Users are reporting they often encounter a 903 i when trying to access your site. Sometimes the site is very slow.
You check your instance pool configuration to confirm that the maximum number of instances Is configured to allow 20 compute instances. Currently 14 compute instances have been provisioned by the Instance pool. You also confirm that current CPU utilization across all hosts exceeds the scale- threshold you set in your auto-scaling policy. However, the Instance pool is not provisioning any new instances.
What can you check to determine why the application is NOT functioning properly?

• A.Verify that the Quality Assurance team is not currently performing load-testing against production.
• B.Verify that the compute resource quota has not been exceeded.
• C.Verify that the new offer feature code did not introduce any performance bugs.
• D.Verify that the database is accessible.

You have created an Autonomous Data Warehouse (ADW) service in your company's Oracle Cloud Infrastructure (OC1) 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 n> CSV text files and these file are ranging in size from 25 MB to 20 GB.
Which step Is most efficient and error tolerant method for loading data Into ADW?

• A.Create Auth token, use it to create an object storage credential by executing DBMS_CI OUD.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 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.
• C.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.
• 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.
