Correct Answer: AFG

Give a tag to the image that you're going to push to Oracle Cloud Infrastructure Registry by entering:

docker tag

where:

uniquely identifies the image, either using the image's id (for example, 8e0506e14874), or the image's name and tag separated by a colon (for example, acme- web-app:latest).

is in the format .ocir.io///: where:

is the key for the Oracle Cloud Infrastructure Registry region you're using. For example, iad. See Availability by Region. ocir.io is the Oracle Cloud Infrastructure Registry name. is the auto-generated

Object Storage namespace string of the tenancy that owns the repository to which you want to push the image (as shown on the Tenancy Information page). For example, the namespace of the acme-dev tenancy might be ansh81vru1zp.

Note that for some older tenancies, the namespace string might be the same as the tenancy name in all lower-case letters (for example, acme-dev). Note also that your user must have access to the tenancy.

(if specified) is the name of a repository to which you want to push the image (for example, project01). Note that specifying a repository is optional (see About Repositories). is the name you want to give the

image in Oracle Cloud Infrastructure Registry (for example, acme-web-app).

is an image tag you want to give the image in Oracle Cloud Infrastructure Registry (for example, version2.0.test).

For example, for convenience you might want to group together multiple versions of the acme-web- app image in the acme-dev tenancy in the Ashburn region into a repository called project01. You do this by including the name of the

repository in the image name when you push the image, in the format .ocir.io///:. For example, iad.ocir.io/ansh81vru1zp/project01/acme-web-app:4.6.3. Subsequently,

when you use the docker push command, the presence of the repository in the image's name ensures the image is pushed to the intended repository. If you push an image and include the name of a repository that doesn't already exist, a new

private repository is created automatically. For example, if you enter a command like docker push iad.ocir.io/ansh81vru1zp/project02/acme-web- app:7.5.2 and the project02 repository doesn't exist, a private repository called project02 is

created automatically. If you push an image and don't include a repository name, the image's name is used as the name of the repository. For example, if you enter a command like docker push iad.ocir.io/ansh81vru1zp/acme-web-app:7.5.2

that doesn't contain a repository name, the image's name (acme-web-app) is used as the name of a private repository. https:// docs.cloud.oracle.com/en-us/iaas/Content/Registry/Concepts/registrywhatisarepository.htm

Correct Answer: C

Invoking a function returns a FunctionInvokeSubnetNotAvailable message and a 502 error (due to a DHCP Options issue)

When you invoke a function that you've deployed to Oracle Functions, you might see the following error message:

{"code":"FunctionInvokeSubnetNotAvailable","message":"dhcp options ocid1.dhcpoptions........ does not exist or Oracle Functions is not authorized to use it"}

Fn: Error invoking function. status: 502 message: dhcp options ocid1.dhcpoptions........ does not exist or Oracle Functions is not authorized to use it If you see this error:

Double-check that a policy has been created to give Oracle Functions access to network resources.

Service Access to Network Resources

When Oracle Functions users create a function or application, they have to specify a VCN and a subnet in which to create them. To enable the Oracle Functions service to create the function or application in the specified VCN and subnet,

you must create an identity policy to grant the Oracle Functions service access to the compartment to which the network resources belong. To create a policy to give the Oracle Functions service access to network resources:

Log in to the Console as a tenancy administrator.

Create a new policy in the root compartment:

Open the navigation menu. Under Governance and Administration, go to Identity and click Policies. Follow the instructions in To create a policy, and give the policy a name (for example, functions- service-network-access).

Specify a policy statement to give the Oracle Functions service access to the network resources in the compartment:

Allow service FaaS to use virtual-network-family in compartment For example:

Allow service FaaS to use virtual-network-family in compartment acme-network Click Create.

Double-check that the set of DHCP Options in the VCN specified for the application still exists.
