## 1. What is a GCP project?

**Answer**

A GCP project is the fundamental organizational unit in Google Cloud Platform. It groups resources (VMs, buckets, databases), users, and billing. Each resource belongs to exactly one project, enabling environment isolation (dev, staging, prod) and access control through IAM.

## 2. What is the format of a Project ID in GCP?

**Answer**

The Project ID is a unique and immutable identifier consisting of 6 to 30 characters (lowercase letters, numbers, hyphens). It is set at project creation and cannot be changed afterward. The Project Name, however, can be modified at any time and has no format constraints.

## 3. What is IAM in Google Cloud Platform?

**Answer**

IAM (Identity and Access Management) is GCP's access management system. It defines who (identity) can do what (role) on which resource. IAM follows the principle of least privilege: granting only necessary permissions. Roles can be assigned to users, groups, or service accounts.
