1Z0-1093-25

The Oracle 1Z0-1093-25 exam, "Oracle Cloud Infrastructure 2022 Certified Associate," focuses on demonstrating foundational knowledge of Oracle Cloud Infrastructure (OCI). The main points covered are broad but can be categorized as follows:

1. Core Infrastructure Services: This is a significant portion of the exam. You need to understand:

• Compute: Virtual Machines (VMs), their lifecycle management, shapes, instance configurations, and networking aspects. Understanding different compute options like bare metal, dedicated, and shared is key.
• Networking: Virtual Cloud Networks (VCNs), subnets, route tables, internet gateways, NAT gateways, security lists, load balancing (both classic and application), and DNS. This section heavily emphasizes understanding network architecture and security.
• Storage: Different storage options (Block Volume, Object Storage, Archive Storage, File Storage), their use cases, performance characteristics, and cost considerations. Understanding backup and recovery strategies is crucial.
• Database: Basic understanding of Oracle Database Cloud Service, including different deployment options and high-level management tasks. You're not expected to be a database administrator, but familiarity with the service is necessary.

2. Security: OCI's security features are a major focus. You should be knowledgeable about:

• Identity and Access Management (IAM): Users, groups, policies, compartments, and how they work together to control access to resources. This is a highly tested area.
• Security Lists: Controlling network traffic in and out of subnets.
• Virtual Private Cloud (VPC) peering: Connecting multiple VCNs securely.
• Data Encryption: Understanding different encryption options at rest and in transit.

3. Management and Governance: You should know how to:

• Monitor and Manage Resources: Using the OCI console, CLI, and APIs for monitoring resource utilization, performance, and costs.
• Cost Management: Understanding billing models and cost optimization strategies.
• Logging and Monitoring: Using OCI Logging and Monitoring services to track resource health and performance.

4. Other Services (Generally less emphasized, but still relevant):

• Container Engine for Kubernetes (OKE): A basic understanding of container services and their deployment.
• Functions: Serverless computing functions.
• High-level understanding of other services like Analytics Cloud, Integration Cloud, and DevOps services. These are typically tested less deeply than the core services listed above.

Important Note: The exam emphasizes practical knowledge and understanding of how OCI services work together. Simple memorization of definitions won't suffice. You need to be able to apply your knowledge to solve common cloud infrastructure problems. Hands-on experience with the OCI console and free tier is highly recommended for preparation.
