1Z0-1085-25

The Oracle 1Z0-1085-25 exam, "Oracle Cloud Infrastructure 2023 Certified Associate," focuses on foundational knowledge of Oracle Cloud Infrastructure (OCI). The main points covered include, but aren't limited to:

1. Core Infrastructure:

• Compute: Understanding virtual machines (VMs), instances, shapes, availability domains, fault domains, and regions. Knowing how to launch, manage, and monitor VMs is crucial. This includes using different compute instance types based on needs.
• Networking: Familiarity with Virtual Cloud Networks (VCNs), subnets, internet gateways, route tables, security lists, and load balancing. Understanding how to create and manage network configurations for security and scalability is key. Knowledge of IP addressing and DNS is important.
• Storage: Understanding different storage services like Object Storage (for unstructured data), Block Volume (for block-level storage), and File Storage (for file-level storage). Knowing their use cases, performance characteristics, and cost implications is vital. Archiving and backup strategies are also relevant.
• Databases: Basic understanding of Oracle Cloud Infrastructure Database services. This may include Autonomous Database (both transactional and data warehouse), and other database options. While in-depth knowledge isn't always expected at the associate level, a general understanding of their purpose and how they fit into the OCI ecosystem is important.

2. Identity and Security:

• Identity and Access Management (IAM): Understanding how to manage users, groups, policies, and compartments to control access to resources within OCI. This is a critical aspect of security.
• Security: General knowledge of security best practices in the cloud, including security lists, network segmentation, and data encryption. Understanding basic security concepts like least privilege is important.

3. Management and Monitoring:

• Monitoring: Understanding the basics of monitoring OCI resources using Oracle Cloud Infrastructure Monitoring. This includes understanding metrics, alerts, and logging.
• Cost Management: Basic awareness of cost management tools and techniques in OCI. Understanding how to track and optimize spending is important for cloud efficiency.

4. Deployment and Management:

• Resource Management: Understanding how to create, manage, and delete resources within OCI. This includes using the console and potentially the command-line interface (CLI).

Important Note: The specific weighting of these topics might vary slightly from exam to exam. Always consult the official Oracle exam guide and practice questions for the most up-to-date information on the exam's content. The focus is on practical, hands-on knowledge rather than purely theoretical concepts. Expect questions that test your understanding of how to use these services within the OCI environment.
