Questions # 1:

What is a key advantage of using virtual nodes in an Oracle Container Engine for Kubernetes cluster?

Options:

They require manual upgrades of the data plane infrastructure.

They provide more configuration flexibility as compared to managed nodes.

They allow for a serverless Kubernetes experience, reducing operational overhead.

They can only be used in basic clusters.

Answer

Explanation

Virtual nodes abstract away the underlying infrastructure management, providing a serverless Kubernetes experience that reduces the operational burden on users.

=================

Questions # 2:

Why are availability domains within the same OCI region connected by a low-latency, high-bandwidth network?

Options:

To reduce the need for encryption between domains

To increase the likelihood of simultaneous failures

To ensure all domains share the same infrastructure

To allow for high-availability connectivity and building replicated systems

Answer

Explanation

The main purpose of connecting availability domains with a low-latency, high-bandwidth network is to enable high-availability connectivity and facilitate the building of replicated systems. This network infrastructure allows for seamless communication between domains, supporting the creation of redundant and resilient systems for increased reliability.

=================

Questions # 3:

Which component of the Oracle Cloud Infrastructure Networking service allows resources in a VCN to access Oracle Cloud services without traversing the public Internet?

Options:

Network Address Translation (NAT) Gateway

Dynamic Routing Gateway (DRG)

Service Gateway

Internet Gateway

Answer

Explanation

A Service Gateway provides secure access to Oracle Cloud services from within a VCN without the need to traverse the public Internet. It facilitates private and efficient communication between resources and cloud services.

=================

Questions # 4:

Which statement best describes Preemptible VMs in OCI?

Options:

They provide a dedicated physical server with no interruption.

They automatically upgrade their operating systems without user action.

They are short-lived instances offered at lower cost, which can be reclaimed by OCI.

They are permanent instances that cannot be shut down by OCI.

Answer

Questions # 5:

In OCI, what is one key reason to choose a Network Load Balancer over the Standard Load Balancer (HTTP/HTTPS)?

Options:

The Network Load Balancer can perform complex Layer 7 routing decisions.

The Network Load Balancer operates at Layer 4, offering lower latency for TCP and UDP traffic.

The Network Load Balancer exclusively supports web (HTTP/HTTPS) protocols.

The Network Load Balancer is used only for database traffic inside a private subnet.

Answer

Explanation

OCI Network Load Balancer provides traffic distribution with high throughput and very low latency. Oracle documents its operation at Layers 3 and 4, making option B the best answer among the available choices. Its listeners support transport-level traffic, including TCP and UDP, without requiring application-level HTTP routing decisions. This makes it suitable for workloads that need efficient connection handling and minimal processing overhead. Depending on its configuration, it can also preserve source IP information. Complex Layer 7 routing is associated with application-aware load balancing. Network Load Balancer supports both public and private deployments, so it is neither restricted to web protocols nor limited to database traffic within private subnets.

Questions # 6:

What is the main purpose of the Auto-Tiering feature in Oracle Cloud Infrastructure Object Storage?

Options:

Giving real-time usage analytics

Allowing unlimited data access patterns

Reducing storage costs by moving objects between Standard and Infrequent

Removing storage fees for large objects

Answer

Explanation

The main purpose of the Auto-Tiering feature in Oracle Cloud Infrastructure Object Storage is to reduce storage costs by automatically moving objects between Standard and Infrequent Access storage tiers based on access patterns. This helps organizations save money by storing less frequently accessed data in a lower-cost storage tier.

=================

Questions # 7:

Which is NOT a type of instance offered by the Oracle Cloud Infrastructure Compute service?

Options:

Virtual Machine

Bare Metal

Dedicated Virtual Machine Host

Nano instance

Answer

Explanation

Nano instances are not offered by OCI. The compute service provides other instance types like Virtual Machines, Bare Metal, and Dedicated Hosts but does not include Nano instances.

=================

Questions # 8:

In Oracle Cloud Infrastructure (OCI), which statement best describes the shared responsibility model for security?

Options:

Oracle is fully responsible for both the security of the cloud and customer workloads.

Security responsibilities are outsourced to third-party security vendors by default.

Oracle secures the underlying cloud infrastructure, while customers secure their workloads and configurations.

The customer is solely responsible for securing all resources and workloads in OCI.

Answer

Explanation

OCI security responsibilities are divided between Oracle and the customer. Oracle protects the infrastructure used to deliver cloud services, including physical facilities, hardware, and underlying networking components. Customers remain responsible for how they use and configure those services, including access policies, application security, data handling, and network security settings. For customer-managed compute environments, responsibilities also include maintaining the operating system and application software. The precise division varies with the service and its level of management, but using OCI does not transfer every security obligation to Oracle. Third-party tools may assist customers without replacing this division of responsibility. Option C best summarizes the model while recognizing that both parties contribute to the overall security of deployed workloads. Oracle documentation: Shared Security Model

Questions # 9:

In the Oracle Cloud Shared Security Model, what is Oracle responsible for?

Options:

Configuring IAM policies for all customers automatically

Controlling user access policies within customer accounts

Securing customer data stored in Object Storage

Managing and securing the physical infrastructure and underlying cloud services

Answer

Questions # 10:

What is the primary purpose of Oracle Cloud Infrastructure Functions?

Options:

To store and manage files

To execute code in response to events or HTTP requests

To provide a managed database service

To deploy and manage virtual machines

Answer

Explanation

Oracle Cloud Infrastructure Functions is a serverless computing service that allows developers to run code without managing servers. It is designed to respond to events or HTTP requests and is ideal for event-driven applications.
