To complete the task of setting up the context for Fn CLI and deploying the python function to exam-app, you can follow these steps:

a. Set up the Fn CLI context in Cloud Shell - In the OCI Console, go to Developer Services and click Functions. - Select your assigned compartment from the list on the left. - Click Getting Started on the top right corner. - Copy and paste the commands from the Set Up Fn CLI Context section into the Cloud Shell window. This will create a new context for your region and compartment. - Set your registry [repo-name-prefix] by entering the following command in the Cloud Shell window:

`fn update context registry [region_key].ocir.io/[tenancy-name]/{username}`

where [region_key] is the region key for your region (for example, iad for US East Ashburn), [tenancy-name] is the name of your tenancy (for example, ocuocictrng16), and {username} is your username (for example, 99248134-lab.user01).

For example, if your region is US East Ashburn, your tenancy is ocuocictrng16, and your username is 99248134-lab.user01, your command would be:

`fn update context registry iad.ocir.io/ocuocictrng16/99248134-lab.user01`

b. Login to the registry using docker login, which will require you to generate and use an Auth Token - To generate an Auth Token, follow these steps: - In the OCI Console, open the Profile menu on the top right corner and click User Settings. - Click Auth Tokens on the left panel and then click Generate Token. - Enter a description for the token and click Generate Token. - Copy and save the token value. You will not be able to see it again later. - To login to the registry using docker login, follow these steps: - In the Cloud Shell window, enter the following command:

`docker login [region_key].ocir.io`

where [region_key] is the region key for your region (for example, iad for US East Ashburn).

For example, if your region is US East Ashburn, your command would be:

`docker login iad.ocir.io`

- Enter your username in the format `[tenancy-name]/oracleidentitycloudservice/{username}` (for example, ocuocictrng16/oracleidentitycloudservice/99248134-lab.user01) and press Enter.

- Enter your Auth Token as the password and press Enter. You should see a message saying 'Login Succeeded'.

c. Use wget https://objectstorage.us-ashburn1.oraclecloud.com/n/ocuocictrng5/b/PBT_Storage/o/ExamFunction-main.zipto upload the zip archive containing the Python function files to Cloud Shell. - In the Cloud Shell window, enter the following command:

`wget https://objectstorage.us-ashburn1.oraclecloud.com/n/ocuocictrng5/b/PBT_Storage/o/ExamFunction-main.zip`

This will download the zip archive to your current directory.

d. Extract the files by using the unzip utility and navigate to the python sub-folder - In the Cloud Shell window, enter the following commands:

`unzip ExamFunction-main.zip`

`cd ExamFunction-main/python`

This will extract the files from the zip archive and change your current directory to the python sub-folder.

e. Deploy the python function to the exam-app using an fn command - In the Cloud Shell window, enter the following command:

`fn deploy --app exam-app --local`

This will deploy the python function to the exam-app application using your local Docker image.

f. Invoke the function at least 2 times using an fn command - In the Cloud Shell window, enter the following command:

`fn invoke exam-app hellopython`

This will invoke the function and print its output.

- You can invoke the function again by repeating the same command or pressing Up Arrow and Enter keys. You should see different outputs each time you invoke the function.

Option A is incorrect because adding an entry in the Security List of the ADW allowing ingress traffic for CIDR block 10.2.2.0/24 will not enable connectivity from the server on the private network to ADW.This is because ADW does not use security lists to control access to its database service2.

Option B is correct because adding an entry in the route table (associated with the private subnet) with destination of 0.0.0.0/0; target type of NAT Gateway, will allow outbound internet access from the server on the private network without exposing its private IP address3. Additionally, adding a stateful egress rule to the security list (associated with the private subnet) with destination of 0.0.0.0/0 and for all IP protocols will allow outbound traffic from any source port to any destination port.

Option C is incorrect because adding an entry in the access control list of ADW for IP address 129.146.160.11 will not enable connectivity from the server on the private network to ADW. This is because this IP address belongs to the NAT gateway, not to the server on the private network.

Option D is incorrect because adding an entry in the route table (associated with the private subnet) with destination of 0.0.0.0/0; target type of Internet Gateway, will expose the private IP address of the server on the private network to the public internet3. This is not recommended for security reasons and may also cause routing conflicts.

Option E is correct because adding an entry in the access control list of ADW for CIDR block 10.2.2.0/24 will allow access from any IP address within that range, including the server on the private network2.

Option A is correct because using multiple OCI Data Transfer Appliances to transfer data to OCI is the most effective service to use to migrate the data to OCI given the time constraints. This option can securely move terabytes or petabytes of data between on-premises data centers and the cloud in days instead of weeks or months.It also avoids using the public internet, which can be slow, unreliable, and expensive45.

Option B is incorrect because setting up an OCI Storage Gateway to connect your data center and your VCN and uploading all data to OCI is not effective given the time constraints. This option requires using the public internet, which can be intermittent due to the damages caused by the hurricane.It also requires installing and configuring a software appliance on your premises, which can add complexity and overhead6.

Option C is incorrect because setting up a hybrid network by launching a 1Gbps FastConnect virtual circuit between your data center and OCI and using OCI Object Storage multipart upload tool to automate the migration of your data to OCI is not feasible given the time constraints. This option requires provisioning a FastConnect circuit, which can take several days or weeks depending on your network provider. It also requires using a public internet backup path, which can be unreliable due to the hurricane .

Option D is incorrect because setting up an OCI Storage Gateway to connect your data center and your VCN and uploading all data to OCI using OCI Storage Gateway Cloud Sync tool is not effective given the time constraints. This option requires using the public internet, which can be intermittent due to the damages caused by the hurricane.It also requires installing and configuring a software appliance on your premises, which can add complexity and overhead6.

Option E is incorrect because uploading the data to OCI using OCI Object Storage multipart upload tool is not effective given the time constraints. This option requires using the public internet, which can be slow, unreliable, and expensive due to the hurricane and the large amount of data involved

Option A is incorrect because using OCI Traffic management service with failover steering policy will not distribute the traffic between OCI and on premises infrastructure.Failover steering policy will only route traffic to a secondary endpoint if the primary endpoint is unresponsive2. This is not suitable for a gradual migration scenario.

Option B is correct because using OCI Traffic management service with Load Balancing steering policy will distribute the traffic between OCI and on premises infrastructure based on a ratio or round robin algorithm2. This will allow you to control the percentage of traffic that goes to the new infrastructure in OCI and monitor the results.

Option C is incorrect because using an OCI load Balancer will not distribute the traffic between OCI and on premises infrastructure.A load balancer will only distribute the traffic among multiple compute instances within a single region in OCI2. This will not help you migrate from your on premises infrastructure.

Option D is incorrect because using VPN connectivity between on premises Infrastructure and OCI and creating routing tables to distribute the traffic between them will require more effort than using OCI Traffic management service.You will need to set up a VPN connection, configure routing rules, and monitor the network performance2. This will not be as simple and reliable as using a DNS-based solution.

Option A is incorrect because rclone is not a tool provided by Object Storage.It is a third-party command-line program that can sync files to and from various cloud storage providers, including Object Storage1.

Option B is incorrect because contiguous numbers are not required for each part.Object Storage constructs the object by ordering part numbers in ascending order only if they are not specified in the commit operation1.

Option C is correct because after initiating a multipart upload, you need to explicitly commit or abort it.Otherwise, it remains active until it expires after 24 hours1.

Option D is incorrect because Object Storage does not provide APIs to split a file into multiple parts.You need to use your own tools or programs to do that1.

Option E is correct because you can list all parts that have been uploaded for an active multipart upload by using the ListMultipartUploadParts API or CLI command.However, you cannot list information for an individual object part by using the GetObject API or CLI command1.
