Oracle Updated 1z0-1085-23 Exam Questions and Answers by asma

Oracle Autonomous Database on Shared Exadata Infrastructure is optimized for transaction processing, data warehousing, and mixed workloads. It is not optimized for high-performance computing, which typically requires specialized hardware and software4

Oracle Functions is the OCI service that can be used for running serverless applications. Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine4.

When you work with Oracle Cloud Infrastructure, one of the first steps is to set up a virtual cloud network (VCN) for your cloud resources.

VIRTUAL CLOUD NETWORK (VCN) :

A virtual, private network that you set up in Oracle data centers. It closely resembles a traditional network, with firewall rules and specific types of communication gateways that you can choose to use. A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice. See Allowed VCN Size and Address Ranges. The terms virtual cloud network, VCN, and cloud network are used interchangeably in this documentation. For more information, see VCNs and Subnets.

SUBNETS :

Subdivisions you define in a VCN (for example, 10.0.0.0/24 and 10.0.1.0/24). Subnets contain virtual network interface cards (VNICs), which attach to instances. Each subnet consists of a contiguous range of IP addresses that do not overlap with other subnets in the VCN. You can designate a subnet to exist either in a single availability domainavailability domain

or across an entire region (regional subnets are recommended). Subnets act as a unit of configuration within the VCN: All VNICs in a given subnet use the same route table, security lists, and DHCP options (see the definitions that follow). You can designate a subnet as either public or private when you create it. Private means VNICs in the subnet can't have public IP addresses. Public means VNICs in the subnet can have public IP addresses at your discretion. See Access to the Internet.

• Master encryption keys are keys that are stored and managed by the Vault service. They are used to encrypt or decrypt data encryption keys or other secrets stored in the Vault service7
• Data encryption keys are keys that are generated by the Vault service and used to encrypt or decrypt data outside of the Vault service, such as data in Object Storage or Block Volume. Data encryption keys are themselves encrypted by master encryption keys and returned to the user as ciphertext
