An administrator needs to execute command-line scripts to manage Azure resources across multiple workstations without manually installing the Azure CLI, PowerShell modules, or developer tools on each local machine.
The solution must satisfy the following requirements:
- Provide a browser-accessible command-line terminal directly from the Azure portal
- Offer a choice between Bash and PowerShell environments
- Automatically persist files and scripts across sessions using cloud storage
Which Azure tool should the administrator use?
Explanations
Azure Lighthouse
Azure Lighthouse
What Azure Lighthouse is
Azure Lighthouse is a cross-tenant management solution designed primarily for managed service providers (MSPs) and multi-tenant enterprise architectures to manage customer or departmental resources securely and efficiently at scale.
Why it doesn't meet the requirement
Azure Lighthouse facilitates delegated resource management and granular cross-tenant access control through Azure Resource Manager. It is not an interactive execution environment, terminal interface, or cloud-hosted shell, and it does not offer pre-configured command-line tools or session file storage.
Key characteristics and limitations
- Cross-tenant visibility: Enables management of multiple distinct Azure Active Directory tenants from a single control plane.
- Delegated access: Uses Azure Resource Manager delegation without requiring user accounts in target customer directories.
- No shell interface: Lacks an embedded browser terminal, CLI tooling, or storage persistence mechanisms.
This answer would be correct if
The requirement focused on enabling an IT service provider to securely access, monitor, and deploy resources across multiple client Azure subscriptions without switching tenant accounts.
Azure Virtual Network NAT
Azure Virtual Network NAT
What Azure Virtual Network NAT is
Azure Virtual Network NAT (Network Address Translation) is a fully managed, resilient networking service that provides outbound-only internet connectivity for subnets within an Azure Virtual Network.
Why it doesn't meet the requirement
Virtual Network NAT is an infrastructure networking component that operates at the transport layer to route outbound network packets. It has no management terminal capabilities, does not interact with PowerShell or Bash, and cannot be used to execute administrative commands against Azure resources.
Key characteristics and limitations
- Outbound connectivity: Provides secure outbound internet traffic for private virtual machine workloads.
- Networking resource: Attaches directly to subnets within a virtual network.
- No CLI or scripting functionality: Does not offer command execution, browser integration, or script storage.
This answer would be correct if
The scenario required providing private virtual machines in an Azure subnet with simplified, secure, outbound-only internet access using static public IP addresses.
Azure Cloud Shell
Azure Cloud Shell
What Azure Cloud Shell is
Azure Cloud Shell is an interactive, authenticated, browser-accessible terminal hosted in the cloud for managing Azure resources. It gives administrators immediate access to a flexible command-line environment directly within the Azure portal, the standalone shell interface, or the Azure mobile app without needing any local software installation.
How it meets the requirements
- Browser-accessible terminal: Azure Cloud Shell runs directly inside modern web browsers, enabling users to authenticate automatically using their current Azure portal credentials.
- Choice of environments: Administrators can switch seamlessly between Bash (utilizing the Azure CLI) and PowerShell (utilizing the Azure Az PowerShell module).
- Persistent cloud storage: On initial setup, Cloud Shell attaches an Azure Files share to persist files, scripts, and user data across different sessions and devices.
Key advantages and capabilities
- Pre-configured environment: Includes pre-installed administrative command-line tools such as
az,kubectl,git, and text editors likecodeandvim. - Zero local maintenance: Eliminates the overhead of configuring, updating, and patching administrative CLI modules on local workstations.
- Secure authentication: Automatically signs in using the identity and role-based access control permissions of the logged-in user.
- Cross-device accessibility: Accessible from any computer or mobile device with an internet connection and a supported web browser.
Why this is optimal
Azure Cloud Shell provides a complete, cloud-hosted management environment that eliminates local dependency issues while maintaining user configuration and scripts through attached Azure storage.
Azure Arc
Azure Arc
What Azure Arc is
Azure Arc is a governance and management platform that extends Azure Resource Manager services and compliance capabilities to infrastructure located outside of Azure, including on-premises servers, multi-cloud virtual machines, and edge Kubernetes clusters.
Why it doesn't meet the requirement
Azure Arc is not an interactive command-line terminal or browser-based shell. While it allows administrators to project non-Azure resources into Azure for unified management and policy enforcement, it does not provide an authenticated shell environment or persistent file storage for executing ad-hoc administrative scripts.
Key characteristics and limitations
- Hybrid management: Connects physical and virtual servers outside Azure into Azure Resource Manager.
- Agent-dependent: Requires installing the Azure Connected Machine agent on target host operating systems.
- No built-in terminal: Does not provide a browser-based Bash or PowerShell command prompt.
This answer would be correct if
The scenario required applying Azure policies, role-based access controls, and central inventory management to on-premises Windows and Linux servers or external cloud virtual machines.
