The Get-BrokerConnectionLog PowerShell cmdlet is the correct tool for reviewing historical connection information within a Citrix Virtual Apps and Desktops site. This command queries the site's database to retrieve records of past connection events, including successful connections, failed connection attempts, and session brokering details. This makes it the appropriate command for an engineer to audit or troubleshoot recent connection and brokering activities.

A. Get-BrokerConnection retrieves details about current and active connections within user sessions, not historical data or brokering attempts.

B. Get-BrokerSession is used to get information about current user sessions on the site, not a log of past connection events.

D. Get-BrokerSessionLog is not a valid cmdlet in the Citrix Broker PowerShell SDK.
