Frequently Asked Questions

Which topics carry the most weight on the 1Z0-1084-25 exam?

Cloud Native Applications and Containerization and Monitoring & Troubleshooting Cloud Native Applications typically account for a larger portion of the exam. However, all five domains are tested, so balanced preparation across each topic is essential. Review the official exam guide to confirm the latest weighting.

How do cloud-native concepts connect to real project workflows?

Cloud Native Fundamentals provide the design principles that guide your choices in containerization and serverless architecture. Testing and security practices are embedded into your development workflow, while monitoring and troubleshooting ensure production reliability. Understanding these connections helps you make informed decisions rather than memorizing isolated facts.

How much hands-on OCI experience do I need before taking the exam?

Practical experience with OCI Container Registry, Functions, and Kubernetes Engine is valuable but not mandatory if you study thoroughly. Prioritize labs that involve deploying a containerized application, triggering serverless functions, and configuring basic monitoring. Even simulated practice in OCI's free tier helps solidify concepts.

What are common mistakes that cost exam points?

Candidates often confuse when to use Functions versus Compute, misunderstand logging and tracing configurations, or overlook security implications of service choices. Carefully read scenario questions for context clues, and review explanations for every practice question to avoid repeating errors.

What is an effective final-week review strategy?

Focus on your weakest topic areas identified during practice tests. Redo scenario-based questions rather than rereading notes. Take one full timed practice test 2-3 days before the exam, review any missed questions, then rest the day before. Avoid cramming new material in the final 24 hours.

Question No. 1

You developed a microservices-based application that runs in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. It has multiple endpoints that need to be exposed to the public internet. What is the most cost-effective way to expose multiple application endpoints without adding unnecessary complexity to the application?

Show Answer Hide Answer
Correct Answer: D

An Ingress Controller is a Kubernetes resource that provides advanced routing and load balancing for your applications running on a Kubernetes cluster1.An Ingress Controller allows you to define rules that specify how to route traffic to different services in your cluster based on the host name or path of the incoming request1.By deploying an Ingress Controller and using it to expose multiple application endpoints, you can achieve the following benefits1:

Cost-effectiveness: You only need to create one load balancer instance per cluster, instead of one per service, which reduces the cost of exposing your applications.

Simplicity: You only need to manage one set of routing rules for all your services, instead of configuring each service separately, which simplifies the application deployment and maintenance.

Flexibility: You can use different types of Ingress Controllers, such as NGINX or Traefik, that offer various features and customization options for your routing needs.


Question No. 2

How are cloud native application versions deployed to an OKE cluster when using a blue/green deployment strategy?

Show Answer Hide Answer
Correct Answer: C

Blue/Green deployment strategy allows releasing a new version of an application using two identical environments where one of them is active at a given time.The current version of the application is provisioned on the active environment, whereas the new version gets deployed to the standby environment1.The traffic is shifted from the active to the standby environment by updating the ingress resource2. Therefore, both old and new application versions are deployed to production at the same time, but only one of them receives the traffic.

Question No. 3

Which TWO are required to access the Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster from the kubectl CLI? (Choose two.)

Show Answer Hide Answer
Correct Answer: C, D

The correct options are: A configured OCI API signing key pair: The API signing key pair is used for authentication and authorization to access OCI resources, including the OKE cluster. The private key should be configured on your local machine to authenticate API requests. An SSH key pair with the public key added to the cluster worker nodes: This is required for secure SSH access to the worker nodes in the OKE cluster. You need to generate an SSH key pair and add the public key to the cluster's worker node pool during cluster creation or update. Therefore, the correct options are having a configured OCI API signing key pair and an SSH key pair with the public key added to the cluster worker nodes.


Question No. 4

A developer using Oracle Cloud Infrastructure (OCI) API Gateway needs to authenticate the API requests to their web application. The authentication process must be implemented using a custom scheme which accepts string-based parameters from the API caller. Which approach should the developer use in this scenario?

Show Answer Hide Answer
Correct Answer: D

In the given scenario, the developer should use the approach of creating an authorizer function using token-based authorization. Token-based authorization is a commonly used approach for authenticating API requests. It involves generating and issuing tokens to API callers, which they can then include in the requests they make to the API. The tokens serve as proof of authentication and are validated by the server to ensure the caller's identity and access rights. By creating an authorizer function using token-based authorization, the developer can implement a custom scheme that accepts string-based parameters from the API caller. This allows the developer to define their own authentication logic and validate the provided tokens according to their requirements. The authorizer function can be configured in the OCI API Gateway to be invoked before forwarding the request to the web application. It will perform the necessary token validation and authentication checks, allowing only authorized requests to access the protected resources of the web application.


Question No. 5

Your Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) administrator has created an OKE cluster with one node pool in a public subnet. You have been asked to provide a log file from one of the nodes for troubleshooting purpose. Which step should you take to obtain the log file?

Show Answer Hide Answer
Correct Answer: C

To obtain a log file from one of the nodes in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster, you should SSH into the nodes using the private key. Here's the step-by-step process: Obtain the private key: The private key is required to authenticate and access the nodes in the OKE cluster. You should obtain the private key from your administrator or the appropriate key pair used to create the cluster. SSH into the node: Use a secure shell (SSH) client, such as OpenSSH, to connect to the desired node in the cluster. The SSH command typically includes the private key file path and the public IP address or hostname of the node. Example command: ssh -i opc@<node_public_ip> Replace with the path to the private key file and <node_public_ip> with the public IP address of the node you want to access. Navigate to the log file location: Once you have successfully connected to the node, navigate to the directory where the log file is located. The exact location and name of the log file may vary depending on the Kubernetes distribution and configuration. Copy or view the log file: You can either copy the log file from the node to your local machine using the scp command or view the contents directly on the node using tools like cat or less. By following these steps, you will be able to access the log file from the desired node in the OKE cluster for troubleshooting purposes.
