NEW QUESTION # 44
Which one of the statements describes a service aggregator pattern?

  • A. It is implemented in each service separately and uses a streaming service
  • B. It involves implementing a separate service that makes multiple calls to other backend services
  • C. It uses a queue on both sides of the service communication
  • D. It involves sending events through a message broker

Answer: B

Explanation:
Service Aggregator Pattern
Another option for eliminating microservice-to-microservice coupling is an Aggregator microservice, shown in purple in Figure 4-10.

The pattern isolates an operation that makes calls to multiple back-end microservices, centralizing its logic into a specialized microservice. The purple checkout aggregator microservice in the previous figure orchestrates the workflow for the Checkout operation. It includes calls to several back-end microservices in a sequenced order. Data from the workflow is aggregated and returned to the caller. While it still implements direct HTTP calls, the aggregator microservice reduces direct dependencies among back-end microservices.

NEW QUESTION # 46
What can you use to dynamically make Kubernetes resources discoverable to public DNS servers?

  • A. kubeDNS
  • B. CoreDNS
  • C. DynDNS
  • D. ExternalDNS

Answer: D

Explanation:
Setting up ExternalDNS for Oracle Cloud Infrastructure (OCI):
Inspired by Kubernetes DNS, Kubernetes' cluster-internal DNS server, ExternalDNS makes Kubernetes resources discoverable via public DNS servers. Like KubeDNS, it retrieves a list of resources (Services, Ingresses, etc.) from the Kubernetes API to determine a desired list of DNS records.
In a broader sense, ExternalDNS allows you to control DNS records dynamically via Kubernetes resources in a DNS provider-agnostic way Deploy ExternalDNS Connect your kubectl client to the cluster you want to test ExternalDNS with. We first need to create a config file containing the information needed to connect with the OCI API.
Create a new file (oci.yaml) and modify the contents to match the example below. Be sure to adjust the values to match your own credentials:
auth:
region: us-phoenix-1
tenancy: ocid1.tenancy.oc1...
user: ocid1.user.oc1...
key: |
-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----
fingerprint: af:81:71:8e...
compartment: ocid1.compartment.oc1...

NEW QUESTION # 47
Which concepthe following steps reference Console instructionsCloud Infrastructure Resource Manager?

  • A. Plan
  • B. Job
  • C. Stack
  • D. Queue

Answer: D

Explanation:
https://docs.cloud.oracle.com/en-us/iaas/Content/ResourceManager/Concepts/resourcemanager.htm Following are brief descriptions of key concepts and the main components of Resource Manager.
CONFIGURATION
Information to codify your infrastructure. A Terraform configuration can be either a solution or a file that you write and upload.
JOB
Instructions to perform the actions defined in your configuration. Only one job at a time can run on a given stack; further, you can have only one set of Oracle Cloud Infrastructure resources on a given stack. To provision a different set of resources, you must create a separate stack and use a different configuration.
Resource Manager provides the following job types:
Plan: Parses your Terraform configuration and creates an execution plan for the associated stack. The execution plan lists the sequence of specific actions planned to provision your Oracle Cloud Infrastructure resources. The execution plan is handed off to the apply job, which then executes the instructions.
Apply. Applies the execution plan to the associated stack to create (or modify) your Oracle Cloud Infrastructure resources. Depending on the number and type of resources specified, a given apply job can take some time. You can check status while the job runs.
Destroy. Releases resources associated with a stack. Released resources are not deleted. For example, terminates a Compute instance controlled by a stack. The stack's job history and state remain after running a destroy job. You can monitor the status and review the results of a destroy job by inspecting the stack's log files.
Import State. Sets the provided Terraform state file as the current state of the stack. Use this job to migrate local Terraform environments to Resource Manager.
STACK
The collection of Oracle Cloud Infrastructure resources corresponding to a given Terraform configuration. Each stack resides in the compartment you specify, in a single region; however, resources on a given stack can be deployed across multiple regions. An OCID is assigned to each stack.
the following steps reference Console instructions
Create a Terraform configuration.
Create a stack.
Run a plan job, which produces an execution plan.
Review the execution plan.
If changes are needed in the execution plan, update the configuration and run a plan job again.
Run an apply job to provision resources.
Review state file and log files, as needed.
You can optionally reapply your configuration, with or without making changes, by running an apply job again.
Optionally, to release the resources running on a stack, run a destroy job.

NEW QUESTION # 51
You want to push a new image in the Oracle Cloud Infrastructure (OCI) Registry. Which two actions do you need to perform?

  • A. Generate an auth token to complete the authentication via Docker CLI.
  • B. Generate an API signing key to complete the authentication via Docker CLI.
  • C. Assign an OCI defined tag via OCI CLI to the image.
  • D. Generate an OCI tag namespace in your repository.
  • E. Assign a tag via Docker CLI to the image.

Answer: A,E

Explanation:
Pushing Images Using the Docker CLI:
You use the Docker CLI to push images to Oracle Cloud Infrastructure Registry.
To push an image, you first use the docker tag command to create a copy of the local source image as a new image (the new image is actually just a reference to the existing source image). As a name for the new image, you specify the fully qualified path to the target location in Oracle Cloud Registry where you want to push the image, optionally including the name of a repository.
For example, assume you have a local image named acme-web-app:latest. Let's say you want to push this image to Oracle Cloud Infrastructure Registry with a name of acme-web-app:version2.0.test into a repository called project01 in the Ashburn region of the acme-dev tenancy. When you use the docker tag command, you'd name the new image with the fully qualified path to its destination, in the format <region-key>.ocir.io/<tenancy-namespace>/<repo-name>/<image-name>:<tag>. So in this case, you'd name the new image iad.ocir.io/ansh81vru1zp/project01/acme-web-app:version2.0.test. Subsequently, when you use the docker push command, the image's name ensures it is pushed to the correct destination.
To push images to Oracle Cloud Infrastructure Registry using the Docker CLI:
If you already have an auth token, go to the next step. Otherwise:

On the Auth Tokens page, click Generate Token.
Enter a friendly description for the auth token. Avoid entering confidential information.
Click Generate Token. The new auth token is displayed.
Copy the auth token immediately to a secure location from where you can retrieve it later, because you won't see the auth token again in the Console.
Close the Generate Token dialog.

NEW QUESTION # 52
Which two statements accurately describe an Oracle Functions application?

  • A. A logical group of functions
  • B. A common context to store configuration variables that are available to all functions in the application
  • C. A Docker image containing all the functions that share the same configuration
  • D. An application based on Oracle Functions, Oracle Cloud Infrastructure (OCI) Events and OCI API Gateway services
  • E. A small block of code invoked in response to an Oracle Cloud Infrastructure (OCI) Events service

Answer: A,B

Explanation:
Oracle Functions Concepts:
This topic describes key concepts you need to understand when using Oracle Functions.
Applications:
In Oracle Functions, an application is:
1. a logical grouping of functions
2. a common context to store configuration variables that are available to all functions in the application
3. a way to ensure function runtime isolation
When you define an application in Oracle Functions, you specify the subnets in which to run the functions in the application. When functions from different applications are invoked simultaneously, Oracle Functions ensures these function executions are isolated from each other.
Oracle Functions shows applications and their functions in the Console.

NEW QUESTION # 53
Which two are benefits of distributed systems?

  • A. Privacy
  • B. Scalability
  • C. Ease of testing
  • D. Security
  • E. Resiliency

Answer: B,E

Explanation:
distributed systems of native-cloud like functions that have a lot of benefit like Resiliency and availability Resiliency and availability refers to the ability of a system to continue operating, despite the failure or sub-optimal performance of some of its components.
In the case of Oracle Functions:
The control plane is a set of components that manages function definitions.
The data plane is a set of components that executes functions in response to invocation requests.
For resiliency and high availability, both the control plane and data plane components are distributed across different availability domains and fault domains in a region. If one of the domains ceases to be available, the components in the remaining domains take over to ensure that function definition management and execution are not disrupted.
When functions are invoked, they run in the subnets specified for the application to which the functions belong. For resiliency and high availability, best practice is to specify a regional subnet for an application (or alternatively, multiple AD-specific subnets in different availability domains). If an availability domain specified for an application ceases to be available, Oracle Functions runs functions in an alternative availability domain.
Concurrency and Scalability
Concurrency refers to the ability of a system to run multiple operations in parallel using shared resources. Scalability refers to the ability of the system to scale capacity (both up and down) to meet demand.
In the case of Functions, when a function is invoked for the first time, the function's image is run as a container on an instance in a subnet associated with the application to which the function belongs. When the function is executing inside the container, the function can read from and write to other shared resources and services running in the same subnet (for example, Database as a Service). The function can also read from and write to other shared resources (for example, Object Storage), and other Oracle Cloud Services.
If Oracle Functions receives multiple calls to a function that is currently executing inside a running container, Oracle Functions automatically and seamlessly scales horizontally to serve all the incoming requests. Oracle Functions starts multiple Docker containers, up to the limit specified for your tenancy. The default limit is 30 GB of RAM reserved for function execution per availability domain, although you can request an increase to this limit. Provided the limit is not exceeded, there is no difference in response time (latency) between functions executing on the different containers.

NEW QUESTION # 57
A service you are deploying to Oracle infrastructure (OCI) Container En9ine for Kubernetes (OKE) uses a docker image from a private repository Which configuration is necessary to provide access to this repository from OKE?

  • A. Add a generic secret on the cluster containing your identity credentials. Then specify a registrycredentials property in the deployment manifest.
  • B. Create a docker-registry secret for OCIR with identity Auth Token on the cluster, and specify the image pull secret property in the application deployment manifest.
  • C. Create a docker-registry secret for OCIR with API key credentials on the cluster, and specify the imagepullsecret property in the application deployment manifest.
  • D. Create a dynamic group for nodes in the cluster, and a policy that allows the dynamic group to read repositories in the same compartment.

Answer: B

Explanation:
Pulling Images from Registry during Deployment
During the deployment of an application to a Kubernetes cluster, you'll typically want one or more images to be pulled from a Docker registry. In the application's manifest file you specify the images to pull, the registry to pull them from, and the credentials to use when pulling the images. The manifest file is commonly also referred to as a pod spec, or as a deployment.yaml file (although other filenames are allowed).
If you want the application to pull images that reside in Oracle Cloud Infrastructure Registry, you have to perform two steps:
- You have to use kubectl to create a Docker registry secret. The secret contains the Oracle Cloud Infrastructure credentials to use when pulling the image. When creating secrets, Oracle strongly recommends you use the latest version of kubectl To create a Docker registry secret:
1- If you haven't already done so, follow the steps to set up the cluster's kubeconfig configuration file and (if necessary) set the KUBECONFIG environment variable to point to the file. Note that you must set up your own kubeconfig file. You cannot access a cluster using a kubeconfig file that a different user set up.
2- In a terminal window, enter:
$ kubectl create secret docker-registry <secret-name> --docker-server=<region-key>.ocir.io --docker-username='<tenancy-namespace>/<oci-username>' --docker-password='<oci-auth-token>' --docker-email='<email-address>' where:
<secret-name> is a name of your choice, that you will use in the manifest file to refer to the secret . For example, ocirsecret
<region-key> 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.
<tenancy-namespace> is the auto-generated Object Storage namespace string of the tenancy containing the repository from which the application is to pull 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).
<oci-username> is the username to use when pulling the image. The username must have access to the tenancy specified by <tenancy-name>. For example, [email protected] . If your tenancy is federated with Oracle Identity Cloud Service, use the format oracleidentitycloudservice/<username>
<oci-auth-token> is the auth token of the user specified by <oci-username>. For example, k]j64r{1sJSSF-;)K8
<email-address> is an email address. An email address is required, but it doesn't matter what you specify. For example, [email protected]
- You have to specify the image to pull from Oracle Cloud Infrastructure Registry, including the repository location and the Docker registry secret to use, in the application's manifest file.

NEW QUESTION # 58
You created a pod called "nginx" and its state is set to Pending.
Which command can you run to see the reason why the "nginx" pod is in the pending state?

  • A. kubect2 get pod nginx
  • B. Through the Oracle Cloud Infrastructure Console
  • C. kubect2 logs pod nginx
  • D. kubect2 describe pod nginx

Answer: D

Explanation:
Debugging Pods
The first step in debugging a pod is taking a look at it. Check the current state of the pod and recent events with the following command:
kubectl describe pods ${POD_NAME}
Look at the state of the containers in the pod. Are they all Running? Have there been recent restarts?
Continue debugging depending on the state of the pods.
My pod stays pending
If a pod is stuck in Pending it means that it can not be scheduled onto a node. Generally this is because there are insufficient resources of one type or another that prevent scheduling. Look at the output of the kubectl describe ... command above. There should be messages from the scheduler about why it can not schedule your pod.

NEW QUESTION # 60
You are tasked with developing an application that requires the use of Oracle Cloud Infrastructure (OCI) APIs to POST messages to a stream in the OCI Streaming service.
Which statement is incorrect?

  • A. The request must include an authorization signing string including (but not limited to) x-content-sha256, content-type, and content-length headers.
  • B. The Content-Type header must be Set to application/j son
  • C. An HTTP 401 will be returned if the client's clock is skewed more than 5 minutes from the server's.
  • D. The request does not require an Authorization header.

Answer: D

Explanation:
Authorization Header
The Oracle Cloud Infrastructure signature uses the "Signature" Authentication scheme (with an Authorization header), and not the Signature HTTP header.
Required Credentials and OCIDs
You need an API signing key in the correct format. See Required Keys and OCIDs.
You also need the OCIDs for your tenancy and user. See Where to Get the Tenancy's OCID and User's OCID.
Summary of Signing Steps
In general, these are the steps required to sign a request:
Form the HTTPS request (SSL protocol TLS 1.2 is required).
Create the signing string, which is based on parts of the request.
Create the signature from the signing string, using your private key and the RSA-SHA256 algorithm.
Add the resulting signature and other required information to the Authorization header in the request.

NEW QUESTION # 61
Which one of the following is NOT a valid backend-type supported by Oracle Cloud Infrastructure (OCI) API Gateway?

  • A. STOCK_RESPONSE_BACKEND
  • B. ORACLE_FUNCTIONS_BACKEND
  • C. HTTP_BACKEND
  • D. ORACLE_STREAMS_BACKEND

Answer: D

Explanation:
In the API Gateway service, a back end is the means by which a gateway routes requests to the back-end services that implement APIs. If you add a private endpoint back end to an API gateway, you give the API gateway access to the VCN associated with that private endpoint.
You can also grant an API gateway access to other Oracle Cloud Infrastructure services as back ends. For example, you could grant an API gateway access to Oracle Functions, so you can create and deploy an API that is backed by a serverless function.
API Gateway service to create an API gateway, you can create an API deployment to access HTTP and HTTPS URLs.

NEW QUESTION # 66
What is the difference between blue/green and canary deployment strategies?

  • A. In blue/green, current applications are slowly replaced with new ones. In < MW y, Application ll deployed incrementally to a select group of people.
  • B. In blue/green, both old and new applications are in production at the same time. In canary, application is deployed Incrementally to a select group of people.
  • C. In blue/green, current applications are slowly replaced with new ones. In canary, both old and new applications are In production at the same time.
  • D. In blue/green, application Is deployed In minor increments to a select group of people. In canary, both old and new applications are simultaneously in production.

Answer: B

Explanation:
Blue-green deployment is a technique that reduces downtime and risk by running two identical production environments called Blue and Green. At any time, only one of the environments is live, with the live environment serving all production traffic. For this example, Blue is currently live and Green is idle.

Canary deployments are a pattern for rolling out releases to a subset of users or servers. The idea is to first deploy the change to a small subset of servers, test it, and then roll the change out to the rest of the servers. ... Canaries were once regularly used in coal mining as an early warning system.

NEW QUESTION # 67
A pod security policy (PSP) is implemented in your Oracle Cloud Infrastructure Container Engine for Kubernetes cluster Which rule can you use to prevent a container from running as root using PSP?

  • A. RunOnlyAsUser
  • B. NoPrivilege
  • C. MustRunAsNonRoot
  • D. forbiddenRoot

Answer: C

Explanation:
What is a Pod Security Policy?
A Pod Security Policy is a cluster-level resource that controls security sensitive aspects of the pod specification. The PodSecurityPolicy objects define a set of conditions that a pod must run with in order to be accepted into the system, as well as defaults for the related fields. They allow an administrator to control the following:
Privilege Escalation
These options control the allowPrivilegeEscalation container option. This bool directly controls whether the no_new_privs flag gets set on the container process. This flag will prevent setuid binaries from changing the effective user ID, and prevent files from enabling extra capabilities (e.g. it will prevent the use of the ping tool). This behavior is required to effectively enforce MustRunAsNonRoot.
example:
# Require the container to run without root privileges.
rule: 'MustRunAsNonRoot'

NEW QUESTION # 68
Which two "Action Type" options are NOT available in an Oracle Cloud Infrastructure (OCI) Events rule definition?

  • A. Functions
  • B. Slack
  • C. Email
  • D. Streaming
  • E. Notifications

Answer: B,C

Explanation:
Overview of Events
Oracle Cloud Infrastructure Events enables you to create automation based on the state changes of resources throughout your tenancy. Use Events to allow your development teams to automatically respond when a resource changes its state.
Event Rules must also specify an action to trigger when the filter finds a matching event. Actions are responses you define for event matches. You set up select Oracle Cloud Infrastructure services that the Events service has established as actions. The resources for these services act as destinations for matching events. When the filter in the rule finds a match, the Events service delivers the matching event to one or more of the destinations you identified in the rule. The destination service that receives the event then processes the event in whatever manner you defined. This delivery provides the automation in your environment.
You can only deliver events to certain Oracle Cloud Infrastructure services with a rule. Use the following services to create actions:
Notifications
Streaming
Functions
