Which two statements about the various types of DevOps tools are true? (Choose two.)

Puppet indeed requires a master-agent architecture where a central Puppet master server manages configurations, and Puppet agents run on client nodes to retrieve and apply those configurations.

SaltStack primarily communicates with clients via its minion agents but also offers proxy minion and agentless modes for specific use cases, making the statement that it 'cannot communicate with clients through general SSH' incorrect.

Puppet is primarily written in Ruby, and Chef is also predominantly Ruby-based; therefore, stating they are written in Python and require Python skills to operate them is false.

Ansible is designed to be agentless, communicating with managed nodes primarily over SSH for Linux/Unix systems and WinRM for Windows, thus not requiring any agent software installation on the target systems.

While Chef and Puppet are powerful tools for system administration tasks, they are widely adopted by DevOps engineers and developers for infrastructure as code, making the statement that they are 'much more attuned to the needs of system administrators' too restrictive.
