Oracle Cloud Infrastructure 2024 Foundations Associate: 1Z0-1085-24

Correct Answer: B

Dynamic Routing Gateway (DRG) is the component of Oracle Cloud Infrastructure Networking service that provides a private connection between a VCN and an on-premises network using VPN or FastConnect. It allows secure communication between the cloud and on-premises resources.

Correct Answer: B

There are 2 types of DB systems on virtual machines:

A 1-node VM DB system consists of one VM.

A 2-node VM DB system consists of two VMs clustered with RAC enabled.

Oracle Cloud Infrastructure offers single-node DB systems on either bare metal or virtual machines, and 2-node RAC DB systems on virtual machines. If you need to provision a DB system for development or testing purposes, then a special

fast provisioning single-node virtual machine system is available.

You can manage these systems by using the Console, the API, the Oracle Cloud Infrastructure CLI, the Database CLI (DBCLI), Enterprise Manager, Enterprise Manager Express, or SQL Developer.

Correct Answer: A

Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN). Large Compute clusters of thousands of instances can use the File Storage service for high-performance shared storage. Storage provisioning is fully managed and automatic as your use scales from a single byte to exabytes without upfront provisioning. The File Storage service supports the Network File System version 3.0 (NFSv3) protocol. The service supports the Network Lock Manager (NLM) protocol for file locking functionality. Oracle Cloud Infrastructure File Storage employs 5-way replicated storage, located in different fault domains, to provide redundancy for resilient data protection. Data is protected with erasure encoding. The File Storage service uses the "eventual overwrite" method of data eradication. Files are created in the file system with a unique encryption key. When you delete a single file, its associated encryption key is eradicated, making the file inaccessible. When you delete an entire file system, the file system is marked as inaccessible. The service systematically traverses deleted files and file systems, frees all the used space, and eradicates all residual files. Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following:
