Cisco Certified Network Professional Practice Test

What kind of interfaces are typically supported on Cisco devices?

1. Ethernet, FastEthernet, GigabitEthernet, TenGigabitEthernet

2. Wireless, Ethernet, Serial, ISDN

3. Ethernet, TokenRing, FDDI, Serial

4. FastEthernet, USB, GigabitEthernet, ATM

The correct answer is: Ethernet, FastEthernet, GigabitEthernet, TenGigabitEthernet

The correct response identifies the types of interfaces that are most commonly found on Cisco devices. Ethernet, FastEthernet, GigabitEthernet, and TenGigabitEthernet are all standard network interfaces used in various Cisco switches and routers to facilitate wired network connectivity. These interfaces support different bandwidths and are essential for building modern network infrastructure, with Ethernet and its variants being the backbone of local area network (LAN) connectivity. Ethernet technology is widely utilized due to its robustness and scalability. FastEthernet typically supports speeds of up to 100 Mbps, GigabitEthernet supports rates up to 1 Gbps, and TenGigabitEthernet allows for even higher speeds up to 10 Gbps. These options are crucial for data transport in enterprise environments, making them highly relevant for Cisco devices. Other choices include interfaces like Serial and ISDN, which are used but not as universally across all Cisco devices as the Ethernet family. Additionally, TokenRing and FDDI interfaces have largely fallen out of favor and are not commonly supported in modern devices. Finally, while options mention USB and ATM, they do not hold the same prominence as the Ethernet categories in the context of network interfaces for general deployment on Cisco hardware.
