NEW QUESTION # 18
Which statement best describes the default AuthZ behavior for users and groups in Oracle Cloud Infrastructure IAM?
- A. Users and groups must request access from the administrator for each resource.
- B. Access to resources in explicitly granted in policies; otherwise, it is denied by default.
- C. Users and groups arc granted access based on their roles without the need for policies.
- D. Users and groups are automatically granted access to all resources.
Answer: B
Explanation:
In Oracle Cloud Infrastructure (OCI) IAM, the principle of least privilege is applied, which means that access to resources is denied by default. Users and groups are granted access explicitly through policies that define the actions allowed on specific resources, ensuring that access is controlled and minimized to what is necessary.

NEW QUESTION # 20
What is the relationship between Oracle Cloud Infrastructure regions and availability domains?
- A. A region encompasses multiple realms, each with its own availability domains.
- B. Regions consist of multiple availability domain, and resources are typically specific to one availability domain.
- C. Availability domains provide low-latency connectivity to the Internet within a region.
- D. Availability domains are isolated from regions and can exist independently.
Answer: B
Explanation:
Oracle Cloud Infrastructure regions consist of one or more availability domains. Each availability domain is a standalone, isolated data center within a region, and resources provisioned in an availability domain are specific to that domain, providing fault tolerance and high availability within a region.
NEW QUESTION # 21
Which Oracle Cloud Infrastructure (OCI) IAM policy statement should be defined to ensure that members of the NetworkAdmins group can create and configure Virtual Cloud Network components in the Project-A compartment?
- A. Allow group NetworkAdmins to manage virtual-network-family in compartment Project-A.
- B. Allow group NetworkAdmins to create virtual-network-family in compartment Project-A.
- C. Allow group NetworkAdmins to read virtual- network- family in compartment Project-A.
Answer: A
Explanation:
To allow members of the NetworkAdmins group to create and configure Virtual Cloud Network (VCN) components within the Project-A compartment, the policy statement should provide 'manage' privileges to the
'virtual-network-family' in that compartment. This allows the group to perform all actions within the virtual network resource family, including creation and configuration.
NEW QUESTION # 22
You need lo store Sunbird ED ansible inventory in a repository that pros ides additional layer of security 10 control access. Which repository would you use?
- A. OCI DevOps Code Repositories
- B. OCI Object Storage
- C. OCI Container Registry (Oracle Cloud Infrastructure Registry OCIR)
- D. OCI DevOps Artifacts
Answer: A
Explanation:
OCI DevOps Code Repositories is a service designed to provide a secure, scalable, and collaborative environment for storing and managing source code. It offers an additional layer of security to control access, making it an ideal choice for storing sensitive configurations like Sunbird ED ansible inventory, ensuring that access to these configurations is tightly controlled and monitored.
NEW QUESTION # 23
Which statement best describes the primary use of the Sunbird client service library (CSL) in an application?
- A. None of these options accurately represents the purpose of CSL within the application.
- B. It employs CSL to execute complex business logic and interact with external APIs.
- C. It leverages CSL to provide a set of common user interface components across the application.
- D. It uses CSL for rendering various forms within the application's user interface.
Answer: B
Explanation:
Client Service Libraries (CSL) are typically used to encapsulate the interactions with backend services, providing a simplified API for front-end applications. They can execute business logic and interact with external APIs, abstracting the complexity of direct service communications.
NEW QUESTION # 24
Which statement is true about how route tables are used in Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and private subnets?
- A. In a private subnet, the default route table allows all outbound traffic to reach the Internet.
- B. Route tables are used exclusively in public subnets to route traffic to the Internet.
- C. Each subnet in a VCN can have multiple route tables associated with it.
- D. Route tables arc created and managed automatically by Oracle Cloud and cannot be customized.
Answer: C
Explanation:
In Oracle Cloud Infrastructure, each subnet within a VCN is associated with a single route table, not multiple route tables. Route tables contain rules to route traffic from subnets to destinations outside the VCN, and they can be used in both public and private subnets. The default routetable for a private subnet does not allow all outbound traffic to reach the Internet without specifically configured rules and an Internet Gateway or NAT Gateway.
NEW QUESTION # 25
Which feature of the OCX Resource Manager service would you use to differentiate between the real-world state of your infrastructure and the slack's last-executed configuration?
- A. Apply or Import State
- B. Drift Detection
- C. View State
- D. Dill Detection
Answer: B
Explanation:
Drift Detection is a feature in OCI Resource Manager that helps users identify discrepancies between the real-world state of their infrastructure and the configuration defined in their Terraform state file. This feature is crucial for maintaining the integrity of infrastructure deployments, as it highlights unintended changes or drifts that might have occurred outside of Terraform's management.
NEW QUESTION # 26
You observe that during peak hours, the resources used in Sunbird ED are not enough for the deployed microservices. What should you do?
- A. Create Volume Groups for the VMs.
- B. Enable Auto-Tiering of the Object Storage bucket.
- C. Create Instance Pools for the virtual machines (VMs) that run the non-containerized workload.
- D. Use the Kubernetes Cluster Autoscaler in (XI Container Engine for Kubernetes.
Answer: D
Explanation:
Using the Kubernetes Cluster Autoscaler with OCI Container Engine for Kubernetes (OKE) is an effective way to dynamically adjust the resources allocated for containerized workloads based on demand. This ensures that during peak hours, additional resources are automatically provisioned to accommodate the increased load, thereby maintaining performance and availability.
NEW QUESTION # 27
Which Cypher query should you use to retrieve the count of nodes with a specific label in a Neo4j HA cluster'.'
- A. MATCH (n) WHERE n.label="Label" RFTURN COUNT(n)
- B. MATCH (n:Label> RETURN COUNT*n)
- C. COUNT (n:Label)
- D. RETURN COUNT(n:Label)
Answer: B
Explanation:
In Neo4j, the Cypher query to retrieve the count of nodes with a specific label would be structured asMATCH (n:Label) RETURN COUNT(n). This query matches all nodes with the specified label and returns the count of these nodes, providing a straightforward way to aggregate nodes based on their labels in a Neo4j database.
NEW QUESTION # 28

NEW QUESTION # 30
How do you replay all the existing messages in a Kafka topic by using the Flink job?
- A. Change the retention period to zero and revert to the previous value for the Kalka topic.
- B. Stop the Mink job. Reset the consumer group offset value to oldest and start the job.
- C. Restart the Flink job.
- D. Increase the number of partitions of the Kalka topic and restart the Flink job.
Answer: B
Explanation:
To replay all messages in a Kafka topic using a Flink job, you would typically stop the job, reset the consumer group offset to the earliest position (often referred to as 'oldest'), and then restart the job. This process ensures that the Flink job will reprocess all messages from the beginning of the topic.
