In the AFCAT 1 2026 Exam, Static General Knowledge (GK) plays a crucial role in testing a candidate’s awareness of world geography and strategic locations. Among these, Straits and International Borders are high-value topics because of their political, economic, and military importance. Understanding these geographical features helps in analysing global trade routes, security dynamics, and international relations.
AFCAT 1 2026 Exam Static GK – Important Straits & International Borders
Important Straits of the World
A strait is a naturally formed narrow waterway that connects two larger bodies of water. Straits are of immense strategic and economic significance because they serve as important maritime chokepoints for global trade.

Strategic Relevance in Defence Exams
In the AFCAT, CDS, and NDA exams, questions often revolve around:
- Location of key straits and their connecting water bodies.
- Borders defining political and military relationships.
- Strategic maritime chokepoints and their global importance.
- Borders related to India and its neighbouring countries.
These topics test both static knowledge and geopolitical awareness, essential for a defence aspirant.
