سؤال 1
What is the correct Google Cloud resource hierarchy?
Google Cloud resources sit inside projects, projects can be grouped in folders, and folders and projects belong to an organization. The other orders are incorrect.
سؤال 2
What is a Google Cloud project?
A project is the base unit that organizes resources, enables APIs, and is linked to billing. VMs, DNS records, and firewall rules are resources inside projects.
سؤال 3
What is a folder used for in Google Cloud?
Folders group projects and let you apply IAM policies and organization policies hierarchically. They do not store images, manage DNS, or filter traffic.
سؤال 4
What is the organization node in Google Cloud?
The organization node is the root that contains folders and projects and supports organization-wide policies. It is not a compute cluster, bucket, or subnet.
سؤال 5
What is a VPC in Google Cloud?
A Virtual Private Cloud is a global network that connects resources with subnets, routes, and firewalls. It is not a VM, schema, or billing account.
سؤال 6
What are regions and zones in Google Cloud?
A region is a geographic area containing multiple zones, and each zone is an isolated facility. DNS zones, folders, and subnets are different concepts.
سؤال 7
What is a multi-region deployment?
Multi-region deployments place resources in several regions to improve availability and durability. A single VM or storage class is not a multi-region deployment.
سؤال 8
What does an SLA define?
An SLA defines service level expectations such as uptime percentage and credits. It does not define projects, machine types, or DNS records.
سؤال 9
What is high availability?
High availability uses redundancy, health checks, and failover so service continues during failures. Expensive machines, single zones, and no backups reduce availability.
سؤال 10
Match each Google Cloud resource hierarchy item to its purpose.
The organization is the root, folders group projects, projects contain resources, and regions are geographic areas with zones.
سؤال 11

Cloud Run runs stateless containers and scales automatically. Compute Engine is VMs, Cloud Storage is objects, and Cloud DNS resolves names.
سؤال 15
What is a managed instance group?
Managed instance groups use instance templates, autoscaling, and health checks to manage identical VMs. Unrelated VMs and network objects are not managed groups.

سؤال 29
Which Google Cloud service provides petabyte-scale object storage with lifecycle management?
Cloud Storage offers scalable object storage with storage classes and lifecycle rules. The other services are databases or analytics.
سؤال 30
Match each Google Cloud data service to its purpose.
Cloud SQL is relational, BigQuery is a warehouse, Firestore is document NoSQL, and Cloud Storage is object storage.
سؤال 31
What is a VPC subnet?
Subnets are IP ranges within a VPC where resources are placed. VMs, firewall rules, and DNS records are different objects.
سؤال 32
Which Google Cloud service distributes traffic across instances and regions?
Cloud Load Balancing distributes traffic across instance groups and regions. DNS resolves names, NAT provides outbound access, and Interconnect is private connectivity.
سؤال 33
Which Google Cloud service provides encrypted tunnels from on-premises networks to a VPC?
Cloud VPN creates encrypted IPsec tunnels over the internet. Interconnect is a private physical connection, CDN caches content, and Armor protects web apps.
سؤال 34
Which Google Cloud service provides dedicated private physical connections to Google?
Cloud Interconnect provides dedicated or partner-managed physical connections. VPN uses encrypted internet tunnels, NAT provides outbound access, and DNS resolves names.
سؤال 35
What does Cloud NAT do?
Cloud NAT lets private VMs reach the internet for outbound connections without public IPs. Load balancers route traffic, CDN caches content, and DNS resolves names.
سؤال 36
What is a VPC firewall rule?
Firewall rules allow or deny traffic based on source, destination, ports, and protocols. A VPC is the network, buckets store objects, and machine types define VMs.
سؤال 37
What is VPC peering?
VPC peering connects two VPCs so resources can communicate privately. Subnets, DNS zones, and billing are separate concepts.
سؤال 38
What is Shared VPC?
Shared VPC lets a host project share its VPC subnets with service projects for centralized network administration. It is not public IPs, DNS, or backup.
