The Imperial Sentinel can be armed with a wide variety of weapons. The original Sentinel design called for a completely open canopy and an Assault Cannon as the walker's standard armament, but eventually this design fell out of use in place of more common weaponry and an armoured or partially armoured canopy.
In the 41st Millennium the Astra Militarum usually equips its Sentinels with whichever weapons are most tactically useful for a given mission or campaign, but some regiments use their own standard pattern of Sentinel.
