Which Oracle Cloud Infrastructure service is responsible for securely storing and managing encryption keys and secrets?. Cloud Guard. Security Advisor. Security Zones. Vault.

Why are availability domains within the same OCI region connected by a low-latency, high-bandwidth network?. To ensure all domains share the same infrastructure. To allow for high-availability connectivity and building replicated systems. To reduce the need for encryption between domains. To increase the likelihood of simultaneous failures.

Why is it important to choose an OCI Region close to your users?. To reduce the cost of cloud storage. To minimize latency and improve application performance. To ensure that only one Availability Domain is used. To enable automatic resource scaling.

What is an availability domain in Oracle Cloud Infrastructure?. A set of virtual cloud networks. One or more data centers located within a region. A type of encrypted traffic. A localized geographical area.

What is the primary purpose of fault domains in Oracle Cloud Infrastructure?. To connect availability domains with low latency. To distribute instances across different physical hardware within an availability domain. To ensure all instances are on the same physical hardware. To handle encryption of traffic between instances.

In the Oracle Cloud Shared Security Model, what is Oracle responsible for?. Securing customer data stored in Object Storage. Configuring IAM policies for all customers automatically. Controlling user access policies within customer accounts. Managing and securing the physical infrastructure and underlying cloud services.

Which feature does the Oracle Cloud Infrastructure Compute service leverage for ensuring high availability of applications?. Golden Gate. Fault Domains. Data Guard. Real Application Clusters (RAC).

Why might you choose to use containers instead of virtual machines?. Containers provide better isolation than virtual machines. Containers require more resources to run. Containers are less flexible in terms of resource allocation. Containers allow for faster startup time and more efficient resource usage.

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 deploy and manage virtual machines. To provide a managed database service.

Which of the following is NOT a use case suitable for OCI Container Instances?. Performing automation tasks for cloud operations. Running APIs and web applications. Running data and media processing jobs. Running containerized apps on Kubernetes.

Which is NOT a type of instance offered by the Oracle Cloud Infrastructure Compute service?. Dedicated Virtual Machine Host. Virtual Machine. Nano instance. Bare Metal.

What does the term "Flexible Shapes" refer to in OCI Compute?. A container orchestration service built on Kubernetes. The name for Oracle's serverless compute option. The capability to customize the number of OCPUs and the amount of memory for certain VM shapes. The ability to run OCI Compute without defining CPU or memory.

What is a key advantage of using virtual nodes in an OCI Kubernetes Engine cluster?. They can only be used in basic clusters. 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.

How are compartment quotas applied in Oracle Cloud Infrastructure?. On a per-tenancy basis. Globally, across all compartments. On a per-region basis. On a per-compartment basis.

What does Oracle Cloud Advisor help you with?. Only security resolutions. Automatically fixing problems. Only cost management. Cost management, performance, and high-availability recommendations.

What is the primary difference between a public subnet and a private subnet in an OCI VCN?. Private subnets can be created only in a separate region from the VCN. Public subnets require a /24 CIDR block, whereas private subnets do not. Public subnets allow resources to have public IP addresses and direct internet access, whereas private subnets do not. Public subnets can host only load balancers, whereas private subnets host databases.

Which component of the Oracle Cloud Infrastructure Networking service allows resources in a VCN to access Oracle Cloud services without traversing the public Internet?. Network Address Translation (NAT) Gateway. Dynamic Routing Gateway (DRG). Service Gateway. Internet Gateway.

In OCI, what is one key reason to choose a Network Load Balancer over the Standard Load Balancer (HTTP/HTTPS)?. The Network Load Balancer operates at Layer 4, offering lower latency for TCP and UDP traffic. The Network Load Balancer can perform complex Layer 7 routing decisions. The Network Load Balancer exclusively supports web (HTTP/HTTPS) protocols. The Network Load Balancer is used only for database traffic inside a private subnet.

What is the primary function of a Route Table in the Oracle Cloud Infrastructure Networking service?. To provide a private connection between a VCN and an on-premises network. To define rules to route traffic from subnets to destinations outside the VCN. To define rules controlling traffic flow between subnets. To connect a VCN to the public Internet.

Which networking component of OCI Virtual Cloud Network provides compute instances in a private subnet with outbound Internet access?. Internet Gateway. Service Gateway. Dynamic Routing Gateway (DRG). Network Address Translation (NAT) Gateway.

Which type of load balancing policy is supported by Oracle Cloud Infrastructure Load Balancer?. Random. Round Weighted. Weighted Round Robin. Weighted Least Connection.

What is the recommended best practice for OCI Tenancy Administrators?. Always enforce Multi-Factor Authentication (MFA) for added security. Avoid creating multiple compartments to simplify resource management. Allow all users to manage policies without restrictions. Use the Tenancy Administrator account for all daily operations.

What is an identity domain in OCI?. A logical container for managing users and groups. A firewall service that controls access to OCI resources. A private subnet used for securing network communications. A physical data center that stores user credentials.

Which statement is NOT true about compartments in Oracle Cloud Infrastructure?. Identity and Access Management (IAM) policies can be written to grant access to resources in specific compartments. Compartments can be nested to create a hierarchy. Compartments are a global resource. Compartments provide a way to store and manage encryption keys and secrets.

Which is NOT a component of an Identity and Access Management (IAM) policy statement in Oracle Cloud Infrastructure?. Action Verb. Location. Resource-type. Data backup frequency.
