Por lo general, el escenario de Packet Tracer se divide en tres zonas interconectadas:
: Configuración de enlaces troncales IEEE 802.1Q y asignación de puertos a VLANs específicas.
Most students are used to the "Logical Workspace" where everything is connected automatically. However, for the PTSA, you will start in . Router(config)# access-list 10 permit 192
is a comprehensive practical exam that tests your ability to design, configure, and secure an enterprise network. In this assessment, you are typically required to work in Packet Tracer's Physical Mode
The is designed to test your ability to implement a functional network, not just memorize definitions. If you are comfortable with OSPF configuration , EtherChannel , STP manipulation , and writing ACLs/NAT , you will pass.

El PTSA de Cisco puntúa de forma incremental mediante scripts internos de Packet Tracer. Sigue este orden lógico para no perder puntos por dependencias:

Antes de aplicar enrutamiento o seguridad, debes establecer la base operativa en routers y switches:
