The easiest way to eliminate back siphonage is to install an air gap or a backflow prevention device in the plumbing system. An air gap creates a physical separation between the water supply and potential contaminants, preventing backflow. Additionally, ensuring proper elevation of hoses and equipment above the flood level can help mitigate the risk. Regular maintenance and inspections of the plumbing system are also essential to prevent back siphonage.
The pipe installed for the purpose of ventilation is known as a vent pipe while a pipe which is installed in a house drainage to preserve the water seal of trap is an anti-siphonage pipe.

No it does not, siphonage is due to inbalanced pressure or incorrect atmospheric pressure in a geyser
Provide air flow to or from drainage system and to protect trap seals from siphonage and backpressure.

The soil vent in the waste line breaks the siphon that would drain traps and toilet bowls by providing a path of least resistance for air pressure. see link
Back siphonage in domestic water systems occurs when there is a drop in water pressure, causing contaminated water to be drawn back into the clean water supply. This can happen due to various reasons, such as a sudden increase in water demand, a burst pipe, or a fire hydrant being opened. The resulting vacuum can pull water from fixtures or hoses that are not properly protected, leading to potential contamination of the potable water supply. Proper backflow prevention devices are essential to mitigate this risk.
