Question 4

You are building a demo for a customer that showcases Oracle Cloud Infrastructure (OCI) Events service and Oracle Functions. You plan to create an event every time an image is uploaded to an OCI Object Storage bucket. You have also created a function that is listening to the event and processes the image for face recognition.

Choose the two actions from below that are NOT required to run the demo successfully.

Select all that apply, then click Submit answer.

○
You must specify an action type while creating an Event service and specify the function you want to trigger.
○
Creating an event rule is not permitted for OCI Object storage.
○
The function must be deployed only to Oracle Kubernetes Engine (OKE).
○
You have to enable Object Storage buckets to emit events for state changes.
○
You must deploy the function that does facial recognition for the demo to work.

Question 5

You have deployed a web application targeting a global audience across multiple Oracle Cloud Infrastructure (OCI) regions.

You decide to use Traffic Management Geo-Location based Steering Policy to serve web requests to users from the region closets to the user. Within each region you have deployed a public load balancer with 4 servers in a backend set. During a DR test disable all web servers in one of the regions however, traffic Management does not automatically direct all users to the other region.

Which two are possible causes?

Select all that apply, then click Submit answer.

○
You did not setup a Route Table associated with load Balancer's subnet
○
You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.
○
Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.
○
One of the two working web servers In the other region did not pass Its HTTP health check
○
You did not correctly setup the Load Balancer HTTP health check policy associated with backend set

Reference / correct answer:

You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.

You did not correctly setup the Load Balancer HTTP health check policy associated with backend set

Managing Traffic Management GEOLOCATION Steering Policies

Geolocation steering policies distribute DNS traffic to different endpoints based on the location of the end user. Customers can define geographic regions composed of originating continent, countries or states/provinces (North America) and define a separate endpoint or set of endpoints for each region.

The Health Checks service allows you to monitor the health of IP addresses and hostnames, as measured from geographic vantage points of your choosing, using HTTP and ping probes. After configuring a health check, you can view the monitor's results. The results include the location from which the host was monitored, the availability of the endpoint, and the date and time the test was performed.

Also you can Combine Managing Traffic Management GEOLOCATION Steering Policies with Oracle Health Checks to fail over from one region to another

The Load Balancing service provides health status indicators that use your health check policies to report on the general health of your load balancers and their components.

if you misconfigure the health check Protocol between the Load balancer and backend set that can lead to not get an accurate response as example below

If you run a TCP-level health check against an HTTP service, you might not get an accurate response. The TCP handshake can succeed and indicate that the service is up even when the HTTP service is ly configured or having other issues. Although the health check appears good customers might experience transaction failures.

Question 6

You have multiple IAM users who launch different types of compute Instances and block volumes every day. As a result, your Oracle cloud Infrastructure (OCF) tenancy quickly hit the service limit and you can no longer create any new instances. As you are cleaning up environment, you notice that the majority of the Instances and block volumes are untagged. Therefore, It is difficult to pinpoint the owner of these resources verify if they are safe to terminate.

Because of this, your company has issued a new mandate, which requires adding compute instances.

Which option is the simplest way to implement this new requirement?

Select an option, then click Submit answer.

○
Create a policy to automatically tag a resource with the user name.
○
Create a policy using IAM requiring users to tag specific resources. This will allow a user to launch compute instances on\y if certain tags were defined.
○
Create tag variables to automatically tag a resource with the user name.
○
Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation
○
Create tag variables for each compartment to automatically tag a resource with the user name.

Reference / correct answer:

Create tag variables to automatically tag a resource with the user name.

Tag Variables

You can use a variable to set the value of a defined tag. When you add the tag to a resource, the variable resolves to the data it represents. You can use tag variables in defined tags and default tags.

Supported Tag Variables

The following tag variables are supported.

${iam.principal.name} The name of the principal that tagged the resource

${iam.principal.type} The type of principal that tagged the resource.

${oci.datetime} The date and time that the tag was created.

Consider the following example:

Operations.CostCenter=" ${iam.principal.name} at ${oci.datetime} "

Operations is the namespace, CostCenter is the tag key, and the tag value contains two tag

variables ${iam.principal.name} and ${oci.datetime} . When you add this tag to a resource, the variable

resolves to your user name (the name of the principal that applied the tag) and a time date stamp for when you added the tag.

user_name at 2019-06-18T18:00:57.604Z

The variable is replaced with data at the time you apply the tag. If you later edit the tag, the variable is gone and only the data remains. You can edit the tag value in all the ways you would edit any other tag value. To create a tag variable, you must use a specific format.

${} Type a dollar sign followed by open and close curly brackets. The tag variable goes between the curly brackets. You can use tag variables with other tag variables and with string values. Tag defaults let you specify tags to be applied automatically to all resources, at the time of creation, in a specific compartment. This feature allows you to ensure that appropriate tags are applied at resource creation without requiring the user who is creating the resource to have access to the tag namespaces.
