1z0-1085-26 Oracle Cloud Infrastructure 2026 Foundations Associate Questions and Answers

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.

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

MySQL Database Service HeatWave is designed to accelerate query performance by offloading analytics to an in-memory columnar store. It enables faster query execution for analytical workloads.

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

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.

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

Compartment quotas are applied on a per-compartment basis in Oracle Cloud Infrastructure. Each compartment has its own set of quota limits for resources and services that are enforced within that compartment.

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

Storing and managing encryption keys and secrets is not a feature provided by Oracle Cloud Infrastructure Security Zones. This functionality is typically handled by other services such as Oracle Key Management Service (KMS) or Vault.

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

Cryptographic operations for a Vault Master Encryption Key protected by an HSM are performed directly on the HSM. The HSM is a specialized hardware device designed to securely generate, store, and perform cryptographic operations, ensuring the confidentiality and integrity of the encryption keys.

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

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.

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

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.

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

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.

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

An availability domain in Oracle Cloud Infrastructure refers to one or more data centers located within a region. Each availability domain is isolated from the others, with its own power, cooling, and networking to ensure fault tolerance and reliability.

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

Storing secrets in a vault provides greater security compared to storing them in code or configuration files. Vaults offer encryption, access controls, audit trails, and other security features to protect sensitive information from unauthorized access or exposure.

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

In OCI, the defining distinction is whether a subnet permits public IP address assignment to its resources. A public subnet permits public IP addresses, while a private subnet prohibits that assignment. Option B is therefore the best answer, but direct internet connectivity is not automatic merely because a subnet is public. An instance also needs a public IP address, an internet gateway, appropriate routing, and security rules that allow the traffic. Private-subnet instances can obtain outbound internet connectivity through a NAT gateway without receiving public IP addresses. Public and private subnets are not restricted to particular application roles, and public subnets do not universally require a /24 address range. Both belong within their VCN’s region.
