NEW QUESTION 48What can you use to dynamically make Kubernetes resources discoverable to public DNS servers? (Choose the best answer.)  kubeDNS  DynDNS  CoreDNS  ExternalDNS To dynamically make Kubernetes resources discoverable to public DNS servers, you can use ExternalDNS.ExternalDNS is a Kubernetes add-on that automates the management of DNS records for your Kubernetes services and ingresses. It can be configured to monitor the changes in your Kubernetes resources and automatically update DNS records in a supported DNS provider. By integrating ExternalDNS with your Kubernetes cluster, you can ensure that the DNS records for your services and ingresses are automatically created, updated, or deleted based on changes in your Kubernetes resources. This allows your Kubernetes resources to be discoverable by external systems through public DNS servers.NEW QUESTION 49You are developing a distributed application and you need a call to a path to always return a specific JSON content deploy an OCI API Gateway with the below API deployment specification. What is the correct value for type? { “routes” : [{ “path” : “/hello”, “methods” : [“Get”), “backend” : { “type” : ” —————- “, “status”: 200, “headers” : [{ “name” : “Content-Type”, “value” : “application/json” }] “body” : “{“myjson”: ” consistent response”}” }}]}  STOCK_RESPONSE_BACKEND  CONSTANT_BACKEND  JSON_BACKEND  HTTP_BACKEND The correct value for the “type” field in the API deployment specification is“STOCK_RESPONSE_BACKEND”. By setting the “type” to “STOCK_RESPONSE_BACKEND”, you are indicating that the backend for the specified route should return a pre-defined response. This type of backend is commonly used when you want a specific response to be returned consistently, regardless of the actual backend service implementation. In this case, the API deployment specification is configured to have a single route with the path “/hello” and the method “GET”. The backend section specifies the type as“STOCK_RESPONSE_BACKEND”. Additionally, it defines the response status code as 200, sets the“Content-Type” header to “application/json”, and provides the JSON content in the “body” field. Using this configuration, any request to the “/hello” path with the “GET” method will always receive a consistent JSON response with the content “{“myjson”: “consistent response”}”.NEW QUESTION 50As a cloud-native developer, you are designing an application that depends on Oracle Cloud Infrastructure (OCI) Object Storage wherever the application is running. Therefore, provisioning of storage buckets should be part of your Kubernetes deployment process for the application. Which of the following should you leverage to meet this requirement? (Choose the best answer.)  Oracle Functions  OCI Service Broker for Kubernetes  Open Service Broker API  OCI Container Engine for Kubernetes To provision storage buckets as part of your Kubernetes deployment process for an application that depends on Oracle Cloud Infrastructure (OCI) Object Storage, you should leverage the OCI Service Broker for Kubernetes. OCI Service Broker for Kubernetes enables you to provision and manage OCI resources, including Object Storage buckets, directly from Kubernetes. It provides a Kubernetes-native experience for managing OCI services, allowing you to define and manage OCI resources as part of your application deployment process. By using the OCI Service Broker for Kubernetes, you can define the required Object Storage buckets in your Kubernetes manifests, and the service broker will handle the provisioning and management of those buckets in OCI, ensuring that they are available for your application wherever it is running.NEW QUESTION 51Which is NOT a valid backend-type option available when configuring an Oracle Cloud Infrastructure (OCI) API Gateway Deployment?  HTTP_BACKEND  ORACLE STREAMS_BACKEND  ORACLE_FUNCTIONS_BACKEND When configuring an OCI API Gateway deployment, you need to specify the backend type for each route in your API deployment specification3. The backend type determines how the API gateway handles requests to that route and forwards them to the appropriate backend service3. The following backend types are valid options for an OCI API Gateway deployment3:* HTTP_BACKEND: The API gateway forwards requests to an HTTP or HTTPS URL as the backend service.* ORACLE_FUNCTIONS_BACKEND: The API gateway invokes an Oracle Functions function as the backend service.* STOCK_RESPONSE_BACKEND: The API gateway returns a stock response without invoking any backend service. ORACLE STREAMS_BACKEND is not a valid backend type for an OCI API Gateway deployment. Oracle Streams is a fully managed, scalable, and durable messaging service that you can use to ingest and consume large amounts of data in real-time4. However, Oracle Streams is not supported as a backend service for an OCI API Gateway deployment.NEW QUESTION 52Your organization is developing serverless applications with Oracle Functions. Many functions will need to store state data in a database, which will require using appropriate credentials. However, your corporate security standards mandate encryption of secret information, such as database passwords. How would you address this security requirement?  Use OCI Console to enter the password in the function configuration section in the provided input field.  Leverage application-level configuration variables to store passwords because they are automatically encrypted by Oracle Functions.  Use the OCI Vault service to auto-encrypt the password and then set an application-level configuration variable to reference the auto-decrypted password inside your function container.  Encrypt the password using the OCI Vault service and then decrypt this password in your function code with the generated key. The best way to store and use secret information, such as database passwords, in Oracle Functions is to use the OCI Vault service. The OCI Vault service provides encryption and decryption capabilities for sensitive data. You can use the OCI Vault service to encrypt the password and store it as an application-level configuration variable. Then, you can use the generated key to decrypt the password in your function code when you need to access the database.

This means that a function running within Oracle Functions cannot exceed a runtime of 5 minutes. If a function requires longer execution times, alternative approaches such as invoking external services asynchronously or using long-running processes should be considered. It is important to design functions with this execution time limitation in mind to ensure optimal performance and efficiency within the Oracle Functions platform.NEW QUESTION 54Which TWO are part of the Cloud Native Computing Foundation (CNCF) container runtime? (Choose two.)  rkt-o  runc  getcd  containerd The two components that are part of the Cloud Native Computing Foundation (CNCF) container runtime are:containerd: containerd is an open-source container runtime that provides a runtime environment for containers, including managing container images, executing containers, and handling container lifecycle events. It is designed to be lightweight and extensible, providing the necessary functionality to run containers efficiently. runc: runc is a lightweight container runtime that serves as a reference implementation of the Open Container Initiative (OCI) runtime specification. It is responsible for launching and managing containers based on OCI specifications, including handling container isolation, namespaces, cgroups, and other low-level container operations. These two components, containerd and runc, are widely used in the container ecosystem and are part of the CNCF’s efforts to promote and develop open-source technologies for cloud-native computing.NEW QUESTION 55Which testing strategy achieves high velocity of deployments and releases of cloud native applications?(Choose the best answer.)  Penetration testing  Automated testing  Integration testing  A/B testing The testing strategy that achieves high velocity of deployments and releases of cloud native applications is“Automated testing.” Automated testing involves the use of automated tools and frameworks to execute tests, validate functionality, and detect issues or bugs in an application. By automating the testing process, developers and DevOps teams can rapidly test and validate code changes, ensuring that new features and updates are functioning correctly before being deployed to production. This approach helps increase the speed and efficiency of the testing process, allowing for faster and more frequent deployments of cloud native applications.NEW QUESTION 56Which concept in OCI Queue is responsible for hiding a message from other consumers for a predefined amount of time after it has been delivered to a consumer?  Maximum retention period  Visibility timeout  Delivery count  Polling timeout Visibility timeout is the concept in OCI Queue that is responsible for hiding a message from other consumers for a predefined amount of time after it has been delivered to a consumer1. The visibility timeout can be set at the queue level when creating a queue, or it can be specified when consuming or updating messages1. If a consumer is having difficulty successfully processing a message, it can update the message to extend its invisibility1. If a message’s visibility timeout is not extended, and the consumer does not delete the message, it returns to the queue1. Verified References: Overview of QueueNEW QUESTION 57Which of these is NOT a valid authentication method for accessing an OCI API Gateway deployment?  HTTP Basic  API Key  OAuth  SAML Token OCI API Gateway supports the following authentication methods for accessing an API deployment3:* HTTP Basic: The client sends a username and password with each request. The credentials are validated against a user database in Oracle Identity Cloud Service (IDCS).* API Key: The client sends an API key with each request. The API key is validated against a list of keys stored in IDCS or OCI Vault.* OAuth: The client obtains an access token from an authorization server (such as IDCS) and sends it with each request. The access token is validated against the authorization server and optionally checked for required scopes.* JWT Token: The client obtains a JSON Web Token (JWT) from an identity provider (such as IDCS or OCI IAM) and sends it with each request. The JWT is validated against the identity provider’s public key and optionally checked for required claims. SAML Token is not a valid authentication method for accessing an OCI API Gateway deployment. SAML is an XML-based standard for exchanging authentication and authorization data between different parties, such as a service provider and an identity provider4. SAML tokens are typically used for web browser single sign-on (SSO) scenarios, not for API access4.NEW QUESTION 58You plan to implement logging in your services that will run in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). Which statement describes the appropriate logging approach?  All services log to an external logging system.  All serviceAAs log to a shared log file.  All services log to standard output only.  Each service logs to its own log file. NEW QUESTION 59You have two microservices, A and B, running in production. Service A relies on APIs from service B. You want to test changes to service A without deploying all of its dependencies, which include service B. Which approach should you take to test service A?  Test using API mocks.  Test the APIs in private environments.  Test against production APIs.  There is no need to explicitly test APIs. API mocking is a technique that simulates the behavior of real APIs without requiring the actual implementation or deployment of the dependent services1. API mocking allows you to test changes to service A without deploying all of its dependencies, such as service B, by creating mock responses for the APIs that service A relies on1. API mocking has several benefits, such as1:* Faster testing: You can test your service A without waiting for service B to be ready or available, which reduces the testing time and feedback loop.* Isolated testing: You can test your service A in isolation from service B, which eliminates the possibility of external factors affecting the test results or causing errors.* Controlled testing: You can test your service A with different scenarios and edge cases by creating mock responses that mimic various situations, such as success, failure, timeout, etc.NEW QUESTION 60You are instructed to automate manual tasks and help software teams manage complex environments at scale using the Oracle Cloud Infrastructure (OCI) services. Which THREE OCI services can be leveraged to securely store and version your application’s source code, and automate the building, testing, and deployment of applications to the OCI platform? (Choose three.)  Container Engine for Kubernetes  DevOps  Oracle Cloud Logging Analytics  Oracle APEX Application Development  Oracle Cloud Infrastructure Registry  Resource Manager The three OCI services that can be leveraged to securely store and version your application’s source code, and automate the building, testing, and deployment of applications to the OCI platform are: DevOps: OCI provides a comprehensive set of DevOps services, including Oracle Developer Cloud Service, which allows you to manage source code repositories, automate builds and testing, and streamline the deployment process.Container Engine for Kubernetes: OCI’s Container Engine for Kubernetes (OKE) enables you to deploy and manage containerized applications using Kubernetes. It provides a scalable and reliable platform for automating the deployment of your applications. Oracle Cloud Infrastructure Registry: OCI Registry is a fully managed, private container registry that allows you to securely store and manage Docker images. It integrates with other OCI services, such as Container Engine for Kubernetes, to facilitate seamless deployment and orchestration of containerized applications. These services combined provide the necessary tools and infrastructure to support continuous integration and continuous deployment (CI/CD) workflows, enabling efficient and automated application development and deployment processes in the Oracle Cloud Infrastructure environment.NEW QUESTION 61Which kubectl command syntax is valid for implementing a rolling update deployment strategy in Kubernetes? (Choose the best answer.)  kubectl upgrade -c <container> –image=image:v2  kubectl update <deployment-name> –image=image:v2  kubectl rolling-update <deployment-name> –image=image:v2  kubectl update -c <container> –iniage=image: v2 The correct syntax for implementing a rolling update deployment strategy in Kubernetes using the kubectl command is: kubectl rolling-update <deployment-name> –image=image:v2 This command initiates a rolling update of the specified deployment by updating the container image to image:v2. The rolling update strategy ensures that the new version of the application is gradually deployed while maintaining availability and minimizing downtime.NEW QUESTION 62You plan to implement logging in your services that will run in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). Which statement describes the appropriate logging approach?  All services log to standard output only.  Each service logs to its own log file.  All services log to an external logging system.  All serviceAAs log to a shared log file. The appropriate logging approach for services running in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) is: “All services log to standard output only.” When running services in a containerized environment like OKE, it is recommended to follow the Twelve-Factor App methodology, which suggests treating logs as event streams. According to this methodology, services should write their log events to standard output (stdout) instead of writing to log files. By logging to standard output, the container runtime (such as Kubernetes) can collect and aggregate the logs generated by the services. These logs can then be accessed and managed through the container runtime’s logging infrastructure. Logging to standard output offers several advantages in a containerized environment: Simplicity and consistency: Standardizing on logging to stdout ensures a consistent approach across different services, making it easier to manage and analyze logs. Log aggregation: The container runtime can collect the logs from all the running containers and provide centralized log management, allowing you to access and search logs from different services in one place. Scalability: Since logs are written to stdout, they can be easily handled by the container runtime’s log management system, which can scale to handle large volumes of log data. Separation of concerns: By logging to stdout, the responsibility of managing log files and their rotation is shifted to the container runtime, allowing the services to focus on their core functionality. While it is possible to log to log files or external logging systems, the recommended approach in a containerized environment like OKE is to log to standard output and leverage the logging infrastructure provided by the container runtime.NEW QUESTION 63Your team has created a serverless application deployed in Oracle Functions. It uses a Python function leveraging the Oracle Cloud Infrastructure (OCI) Python SDK to stop any OCI compute instance that does not comply with your corporate security standards. Although there are three non-compliant OCI compute instances, when you invoke this function, none of the instances were stopped. With respect to this issue, which of the following is a valid troubleshooting strategy?  Enable function logging in the OCI console, add some print statements in your function code, and then view the logs to troubleshoot.  Enable function remote debugging in the OCI console, and then use your favorite IDE to inspect the function running on Oracle Functions.  Ensure that the application is deployed within the same OCI compartment as the instance, because you cannot enable function execution data from the OCI console.  Enable function tracing in the OCI console, and then go to the OCI Monitoring console to view the function stack trace. The valid troubleshooting strategy in this scenario is to enable function logging in the OCI console, add some print statements in your function code, and then view the logs to troubleshoot. Enabling function logging allows you to capture and store logs generated by your function during its execution. By adding print statements or log statements in your function code, you can output relevant information and debug messages to the logs. This helps you understand the execution flow, identify any errors or issues, and gather more information about the function’s behavior. To troubleshoot the issue of the Python function not stopping the non-compliant OCI compute instances, you can follow these steps: Enable function logging in the OCI console: Enable logging for your function to ensure that logs are captured during its execution. Modify your function code: Add relevant print statements or log statements at key points in your code to output debug information or verify the execution flow. For example, you can print the instance details that are being evaluated for compliance. Invoke the function: Trigger the function execution either through an event or manually. View the logs: Access the function logs in the OCI console or retrieve them programmatically.Look for the expected print statements or log entries that indicate the status of each instance and the decisions made by the function. By reviewing the logs, you can analyze the output and identify any issues or discrepancies. It can help you determine if the function is correctly evaluating the compliance criteria, retrieving the instance details, or making the necessary API calls to stop the instances. You may need to adjust your code logic or investigate further based on the information provided in the logs. Enabling function remote debugging is not a suitable strategy in this case because it is primarily used for inspecting and debugging the function code during development, rather than troubleshooting issues in a deployed function. Enabling function tracing can provide insights into the execution flow and performance of the function but may not directly address the issue of the instances not being stopped. Ensuring that the application is deployed within the same OCI compartment as the instance is not directly related to troubleshooting the issue with the non- compliant instances. It is a consideration for access and permissions but does not provide specific insights into the problem at hand. Remember to refer to the Oracle Functions documentation and consult the official resources for detailed instructions and best practices on troubleshooting and monitoring Oracle Functions.NEW QUESTION 64Which testing measure should be considered when using test cases that simultaneously validate a deployment and perform a selected set of functional tasks?  Resource Utilization  Functionality  Scalability  Robust Deployment  Resiliency The correct answer is: “Robust Deployment.” When using test cases that simultaneously validate a deployment and perform a selected set of functional tasks, the testing measure that should be considered is“Robust Deployment.” Robust Deployment refers to the ability of an application or system to be deployed reliably and consistently, without errors or failures. It involves ensuring that the deployment process is well- defined, automated, and able to handle different scenarios and configurations. When conducting testing that combines the validation of deployment and functional tasks, it is crucial to ensure that the deployment itself is robust. This means verifying that the application or system can be successfully deployed and configured without encountering deployment-related issues such as incorrect configurations, missing dependencies, or compatibility problems. By considering “Robust Deployment” as a testing measure, you can evaluate the reliability and effectiveness of the deployment process, ensuring that the application or system is deployed correctly and ready to perform the selected set of functional tasks. Loading … Get Instant Access to 1z0-1084-24 Practice Exam Questions: https://www.dumpleader.com/1z0-1084-24_exam.html --------------------------------------------------- Images: https://blog.dumpleader.com/wp-content/plugins/watu/loading.gif https://blog.dumpleader.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2024-11-19 16:20:45 Post date GMT: 2024-11-19 16:20:45 Post modified date: 2024-11-19 16:20:45 Post modified date GMT: 2024-11-19 16:20:45
