QUESTION 16
What is the primary purpose of fault domains in Oracle Cloud Infrastructure?

To ensure all instances are on the same physical hardware

To distribute instances across different physical hardware within an availability domain

To connect availability domains with low latency

To handle encryption of traffic between instances

Fault domains in Oracle Cloud Infrastructure are used to distribute instances across different physical hardware within an availability domain. This helps in ensuring high availability and fault tolerance by reducing the impact of hardware failures on instances.

QUESTION 17
Which Oracle Cloud Infrastructure service is responsible for securely storing and managing encryption keys and secrets?

Cloud Guard

Security Zones

Security Advisor

Vault

Vault is the Oracle Cloud Infrastructure service responsible for securely storing and managing encryption keys and secrets. It provides a centralized and secure location for managing sensitive information such as encryption keys, passwords, and API keys.

QUESTION 18
Which feature of Oracle Cloud Infrastructure Object Storage Service enables users to automatically move objects between storage tiers based on predefined rules?

Object Versioning

Object Lifecycle Management

Pre-Authenticated Requests

Cross-Region Replication

Object Lifecycle Management in Oracle Cloud Infrastructure Object Storage Service enables users to define rules to automatically move objects between different storage tiers based on predefined criteria such as age, size, or custom metadata. This feature helps optimize storage costs by ensuring that objects are stored in the most cost-effective tier.

QUESTION 19
In Oracle Cloud Infrastructure, what does the Universal Credits pricing model allow customers to do?

Pay only for services they use with no upfront commitment

Use prepaid credits for any eligible cloud service

Receive a fixed amount of resources for a specific price

Pay a fixed price for all services

Using prepaid credits for any eligible cloud service is a feature of the Universal Credits pricing model in Oracle Cloud Infrastructure. Customers can allocate their prepaid credits to various services based on their needs and usage.

QUESTION 20
Which networking component of OCI Virtual Cloud Network provides compute instances in a private subnet with outbound Internet access?

Internet Gateway

Network Address Translation (NAT)

Dynamic Routing Gateway (DRG)

Service Gateway

QUESTION 21
What is the primary purpose of Oracle Cloud Infrastructure Functions?

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

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.

QUESTION 22
What is the main purpose of the Auto-Tiering feature in Oracle Cloud Infrastructure Object Storage?

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

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.

QUESTION 23
Which type of load balancing policy is supported by Oracle Cloud Infrastructure Load Balancer?

Random

Weighted Round Robin

Round Robin

Weighted Least Connection

Weighted Round Robin is a load balancing policy that distributes traffic based on weights assigned to backend servers. It provides more control over traffic distribution, allowing higher-weighted servers to receive more requests.

QUESTION 24
Why might you choose to use containers instead of virtual machines?

Containers provide better isolation than virtual machines.

Containers allow for faster startup time and more efficient resource usage.

Containers require more resources to run.

Containers are less flexible in terms of resource allocation.

Containers share the host operating system’s kernel, leading to quicker startup times and lower overhead compared to virtual machines. They offer more agility and resource efficiency, making them suitable for scalable applications.

QUESTION 25
Which of the following is NOT a use case suitable for OCI Container Instances?

Running APIs and web applications

Performing automation tasks for cloud operations

Running containerized apps on Kubernetes

Running data and media processing jobs

OCI Container Instances are designed for simpler workloads, whereas running containerized apps at scale on Kubernetes requires a container orchestration platform, which is a different use case.

QUESTION 26
Which performance level is NOT available in the Oracle Cloud Infrastructure Block Volume service?

Balanced

Higher Performance

Ultra High Performance

Low Performance

The Low Performance level is NOT available in the Oracle Cloud Infrastructure Block Volume service. This option does not exist as a performance level for block volumes in OCI.

QUESTION 27
Which is NOT a type of instance offered by the Oracle Cloud Infrastructure Compute service?

Virtual Machine

Bare Metal

Dedicated Virtual Machine Host

Nano instance

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.

QUESTION 28
What is the primary purpose of a Network Security Group (NSG) in the Oracle Cloud Infrastructure Networking service?

To connect a VCN to the public Internet

To control traffic flow between specific resources within a VCN

To control traffic routing between VCNs

To provide a private connection between a VCN and an on-premises network

Network Security Groups (NSGs) act as virtual firewalls in OCI, controlling inbound and outbound traffic for specific resources within a VCN. You can define rules based on IPs, ports, and protocols.

QUESTION 29
Why are availability domains within the same OCI region connected by a low-latency, high-bandwidth network?

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

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.

QUESTION 30
Which Oracle Cloud Infrastructure (OCI) offering allows you to run cloud services in your own data center while maintaining regulatory compliance?

Oracle Database@Azure

Oracle Database Service for Azure

OCI Dedicated Region

MySQL HeatWave Database Service

OCI Dedicated Region provides a fully managed Oracle Cloud Infrastructure region in a customer’s data center, allowing them to meet regulatory compliance while running cloud services on-premises.

QUESTION 31
What is a key feature of Oracle Cloud Infrastructure Functions?

It requires extensive infrastructure administration.

It is limited to running only Java applications.

It requires manual provisioning of compute instances.

It automatically applies operating system software patches and upgrades.

OCI Functions automatically handles operating system patches and upgrades, ensuring that the functions are secure and up-to-date without requiring manual maintenance from users.

QUESTION 32
Which statement best describes the default AuthZ behavior for users and groups in OCI Identity and Access Management?

Users and groups must request access from the administrator for each resource.

Users and groups are granted access based on their roles without the need for policies.

Users and groups are automatically granted access to all resources.

Access to resources is explicitly granted in policies; otherwise, it is denied by default.

In OCI, users and groups must be explicitly granted access to resources through IAM policies. If access is not granted in a policy, it is denied by default, ensuring controlled access.
