What kind of network device is a Cisco ISR?

• A. Switch
• B. Router
• C. Gateway
• D. Repeater

Answer: (B)

A Cisco Integrated Services Router (ISR) is a type of network device primarily designed to route data between different networks. It's a versatile piece of equipment that combines multiple functions—such as routing, switching, security, and voice services—into a single platform. ISRs are used to connect branch offices to external networks, such as the internet, and can support various WAN technologies, making them ideal for managing network traffic efficiently. By supporting diverse protocols and providing advanced services like quality of service (QoS) and firewall capabilities, ISRs enhance network performance while also securing data transmissions. They play a crucial role in modern networking by enabling organizations to build robust, scalable, and integrated communication systems.
