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 correct because deploying a Virtual Machine RAC DB system on OCI and using the ZDM tool for the database migration is a method that can minimize the impact on the application. ZDM is a software solution that allows you to directly and seamlessly migrate your on-premises Oracle Databases to the Oracle Cloud, whether in OCI or ExaCC.ZDM supports a wide range of Oracle Database versions, and ensures that there is minimal to no production downtime during the migration1.ZDM also supports migrating RAC databases to RAC databases on OCI2.

Option B is incorrect because deploying an Autonomous Transaction Processing Database on OCI and using the MV2ADB tool for the database migration is not a suitable method for this scenario. MV2ADB is a command-line tool that allows migrating data from an Oracle database on-premise to Oracle Autonomous Database in ''one-click''.It is based on Oracle Data Pump export and import utility3.However, MV2ADB does not support migrating RAC databases to Autonomous Database, nor does it support migrating Enterprise Edition databases to Autonomous Database4.

Option C is incorrect because deploying an Exadata Cloud Service Base rack and using Oracle Data Pump tool to migrate the data from customer on-premises to OCI is not a method that can minimize the impact on the application.Oracle Data Pump is a technology that enables you to move data and metadata from one database to another5. However, Oracle Data Pump requires intermediate storage for the dump files, which can add complexity and overhead. It also requires downtime during the export and import operations, which can affect the availability of the application.

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

To complete the task of creating a public API Gateway and invoking a private function in OCI, you can follow these steps:

To create a new public API Gateway in your compartment named exam-gateway, follow these steps:

In the OCI Console, go toDeveloper Servicesand clickAPI Gateway.

Select your assigned compartment from the list on the left.

ClickCreate Gateway.

Enterexam-gatewayas theNameand selectPublicas theType. You can also add a description for the gateway if you want.

Select your previously created VCN from theVCNdropdown menu and select any subnet from theSubnetdropdown menu. You can also enable logging for the gateway if you want.

ClickCreate. This will create a new public API Gateway in your compartment that can expose your functions to the internet.

To create a new API Deployment named exam-deployment using /v1 as the path prefix in exam-gateway, follow these steps:

In the OCI Console, go toDeveloper Servicesand clickAPI Gateway.

Select your assigned compartment from the list on the left and click on your previously created gateway (exam-gateway).

ClickDeploymentson the left panel and then clickCreate Deployment.

Enterexam-deploymentas theNameand selectFrom Scratchas theSpecification Type. You can also add a description for the deployment if you want.

Enter /v1 as thePath Prefixand leave the other fields as default. ClickNext.

To create a new route by using /hello as the path and GET as the method, follow these steps:

In the Create Deployment dialog box, clickAdd Route.

Enter /hello as thePath, select GET as theMethod, and select Oracle Functions as theType.

Select your previously created function (hello-python) from theFunction Namedropdown menu and leave the other fields as default. ClickSave Changes. This will create a new route that will invoke your function when you send a GET request to /v1/hello.

To create a new stateful CIDR Ingress Rule that allows for TCP HTTPS traffic (port 443) from all IP addresses and ports in the default Security List for exam-vcn, follow these steps:

In the OCI Console, go toNetworkingand clickVirtual Cloud Networks.

Select your assigned compartment from the list on the left and click on your previously created VCN (exam-vcn).

ClickSecurity Listson the left panel and then click on the default security list for your VCN.

ClickEdit All Rulesand then clickAdd Ingress Ruleunder the Ingress Rules section.

Enter 0.0.0.0/0 as theSource CIDR, select TCP as theIP Protocol, and enter 443 as both theSource Port Rangeand theDestination Port Range. You can also add a description for the rule if you want.

ClickSave Security List Rules. This will create a new stateful CIDR Ingress Rule that will allow HTTPS traffic from any source to reach your API Gateway.

To use curl to call the function via your API Gateway deployment, follow these steps:

In the OCI Console, go toDeveloper Servicesand clickAPI Gateway.

Select your assigned compartment from the list on the left and click on your previously created gateway (exam-gateway).

ClickDeploymentson the left panel and then click on your previously created deployment (exam-deployment).

Copy the value of the Endpoint URL field. This is the base URL for your API Deployment.

In a terminal window, enter the following command:

curl -k -X GET {deployment-endpoint}/v1/hello

where {deployment-endpoint} is the base URL that you copied.

For example, if your deployment endpoint is https://abc123xyz456.apigateway.us-ashburn-1.oci.customer-oci.com, your command would be:

curl -k -X GET https://abc123xyz456.apigateway.us-ashburn-1.oci.customer-oci.com/v1/hello

This will send a GET request to your API Deployment and invoke your function. You should see a response similar to this:

{'message': 'Hello World!'}

Topic 2, Multiple Choice Questions

One possible IAM policy statement that allows API Gateway to access Oracle Functions in your compartment is:

ALLOW any-user to use functions-family in compartment <your-compartment-name> where ALL {request.principal.type = 'ApiGateway', request.resource.compartment.id = '<your-compartment-OCID>'}

This statement grants the any-user group the permission to use the functions-family resource type in the specified compartment, but only if the request is coming from an API Gateway and the function belongs to the same compartment as the API Gateway.
