You created an Oracle Linux compute instance through the Oracle Cloud Infrastructure (OCI) management console then immediately realize you forgot to add an SSH key file. You notice that OCI compute service provides instance console connections that supports adding SSH keys for a running instance. Hence, you created the console connection for your Linux server and activated it using the connection string provided. However, now you get prompted for a username and password to login.
What option should you recommend to add the SSH key to your running instance, while minimizing the administrative overhead? (Choose the best answer.)

• A.You need to configure the boot loader to use ttyS0 as a console terminal on the VM.
• B.You need to modify the serial console connection string to include the identity file flag, -i to specify the SSH key to use.
• C.You need to terminate the running instance and recreate it by providing the SSH key file.
• D.You need to reboot the instance from the console, boot into the bash shell in maintenance mode, and add SSH keys for the opc user.

You have a 750 MIB file in an Oracle Cloud Infrastructure (OCI) Object Storage bucket. You want to download the file in multiple parts to speed up the download using the OCI CLI. You also want to configure each part size to be 128 MIB.
Which is the correct OCI CLI command for this operation? (Choose the best answer.)

• A.oci os object download -ns my-namespace -bn my-bucket --name my-large-object -- multipart-download-threshold 750 --parallel-download-count 128
• B.oci os object get -ns my-namespace -bn my-bucket --name my-large-object -- multipart-download-threshold 750 --parallel-download-count 128
• C.oci os object download -ns my-namespace -bn my-bucket --name my-large-object -- resume-put --multipart-download-threshold 500 --part-size 128
• D.oci os object get -ns my-namespace -bn my-bucket --name my-large-object -- multipart-download-threshold 500 --part-size 128

You have been contracted by a local e-commerce company to assist with enhancing their online shopping application. The application is currently deployed in a single Oracle Cloud Infrastructure (OCI) region. The application utilizes a public load balancer, application servers in a private subnet, and a database in a separate, private subnet.
The company would like to deploy another set of similar infrastructure in a different OCI region that will act as standby site. In the event of a failure at the primary site, all customers should be routed to the failover site automatically.
After deploying the additional infrastructure within the second region, how should you configure automated failover requirements? (Choose the best answer.)

• A.Create a load balancer policy in the Traffic Management service. Configure one answer for each site. Set the answer for the primary site with a weight of 10 and the answer for the secondary site with a weight of 100.
• B.Deploy a new load balancer in the primary region. Create one backend set for the primary application servers and a second backend set for the standby application servers. Create a listener for the primary backend set with a timeout of 3 minutes. Create a listener for the secondary backend set with a timeout of 10 minutes.
• C.Create a new A record in DNS that points to the public load balancer at the secondary site. Create a CNAME for the sub-domain failover that will resolve to the new A record. Inform customers to prepend the website URL with failover if the primary site is unavailable.
• D.Create a failover policy in the Traffic Management service. Set the IP address of the public load balancer for the primary site in answer pool 1. Set the IP address of the public load balancer for the secondary site in answer pool 2. Define a health check to monitor both sites.

Your application is using an Object Storage bucket named app-data in the namespace vision, to store both persistent and temporary dat a. Every week all the temporary data should be deleted to limit the storage consumption.
Currently you need to navigate to the Object Storage page using the web console, select the appropriate bucket to view all the objects and delete the temporary ones.
To simplify the task you have configured the application to save all the temporary data with /temp prefix. You have also decided to use the Command Line Interface (CLI) to perform this operation.
What is the command you should use to speed up the data cleanup? (Choose the best answer.)

• A.oci os object delete -ns vision -bn app-data --prefix /temp
• B.oci os object bulk-delete -ns vision -bn app-data --prefix /temp --force
• C.oci objectstorage bulk-delete -ns vision -bn app-data --prefix /temp --force
• D.oci os object delete app-data in vision where prefix = /temp
