Dumpleader has created budget-friendly 1z0-1084-26 study guides because the registration price for the Oracle certification exam is already high. You won't ever need to look up information in various books because our Oracle 1z0-1084-26 Real Questions are created with that in mind. Additionally, in the event that the curriculum of Oracle changes, we provide free upgrades for up to three months.

NEW QUESTION # 135
You 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?
Answer: C
Explanation:
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 # 136
You 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.)
Answer: A,C,E
Explanation:
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 # 137
In the DevOps lifecycle, what is the difference between continuous delivery and continuous deployment?
(Choose two.)
Answer: B,D
Explanation:
The two correct differences between continuous delivery and continuous deployment in the DevOps lifecycle are: Continuous delivery is a process that initiates deployment manually, while continuous deployment is based on automating the deployment process. In continuous delivery, the software is ready for deployment, but the decision to deploy is made manually by a human. On the other hand, continuous deployment automates the deployment process, and once the software passes all the necessary tests and quality checks, it is automatically deployed without human intervention. Continuous delivery involves automatic deployment to a development environment, while continuous deployment involves automatic deployment to a production environment. In continuous delivery, the software is automatically deployed to a development or staging environment for further testing and validation. However, the actual deployment to the production environment is performed manually. In continuous deployment, the software is automatically deployed to the production environment, eliminating the need for manual intervention in the deployment process. These differences highlight the level of automation and human involvement in the deployment process between continuous delivery and continuous deployment approaches in the DevOps lifecycle.
NEW QUESTION # 138
You are designing an automated integration testing strategy for a containerized microservice deployed to an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. The microservice ' s integration tests must write test events to an OCI Stream within a specific compartment. To comply with security mandates, you must avoid the use of hardcoded credentials, long-lived API signing keys, or manual token injection during the automated test execution. Which TWO configurations are required to securely authorize the test suite to access the OCI Streaming service? (Choose TWO.)
Answer: B,C
Explanation:
For OKE workloads running on managed worker nodes, OCI Instance Principals provide credential-free access to OCI APIs. Oracle documents creating a dynamic group containing the worker-node Compute instances, commonly using a matching rule based on instance.compartment.id, and then granting that dynamic group appropriate permissions through an IAM policy. Streaming permissions can authorize publishing to streams without embedding user credentials in application configuration. Hardcoded Auth Tokens violate the stated security requirement, root privileges do not bypass OCI IAM authentication, and security lists only control network traffic rather than service authorization. For modern enhanced OKE clusters, Oracle now provides Workload Identity for finer-grained pod-level authorization and recommends it where appropriate; however, among the options supplied, the documented instance-principal configuration is A and B.
NEW QUESTION # 139
You are developing a serverless application with Oracle Functions and Oracle Cloud Infrastructure Object Storage. Your function needs to read a JSON file object from an Object Storage bucket named " input-bucket
" in compartment " qa-compartment " . Your corporate security standards mandate the use of Resource Principals for this use case. Which two statements are needed to implement this use case? (Choose two.)
Answer: B,C
Explanation:
The correct answers are: Set up the following dynamic group for your function ' s OCID: Name: read-file-dg Rule: resource.id = " ocid1.fnfunc.oc1.phx.aaaaaaaakeaobctakezjz5i4ujj7g25q7sx5mvr55pms6f4da " Set up a policy with the following statement to grant read access to the bucket: Statement: allow dynamic-group read- file-dg to read objects in compartment qa-compartment where target.bucket.name = ' input-bucket ' Explanation: To implement the use case of reading a JSON file object from an Object Storage bucket using Resource Principals with Oracle Functions, you need to configure the following: Create a dynamic group named " read-file-dg " and associate it with your function ' s OCID. This dynamic group helps identify the function as a member of the group for policy enforcement. Create a policy that grants read access to the bucket. The policy statement should allow the dynamic group " read-file-dg " to read objects in the compartment " qa-compartment " and specify the target bucket name as " input-bucket " . This policy ensures that the function has the necessary permissions to access the specified bucket. By setting up the dynamic group and policy, you ensure that the function, as a member of the dynamic group, has the required read access to the specified Object Storage bucket in the specified compartment.
