Which type of competitive strategy is characterized by convincing rivals not to enter a price war, protection from customer pressure to lower prices, and the ability to better withstand cost increases from suppliers?

Overall cost leadership.

Explanation:

Cost leadership can be defined as to lowest cost that is available in an industry. A cost leader in an industry has achieved a competitive advantage by being able to give the lowest price compared to other businesses in the market

So to avoid overall cost leadership firms convince rivals not to enter a price war, protection from customer pressure to lower prices, and the ability to better withstand cost increases from suppliers.
