Please select an optionIncorrectCorrect answer: A
show inventory lists each hardware component with its product ID, description and serial number, including the chassis serial. show version reports software details, and show platform focuses on hardware slot status.
Was this answer correct?Question #6
What is the primary role of a switch in a local area network?
Please select an optionIncorrectCorrect answer: C
A switch forwards frames per port, so each port is its own collision domain, eliminating contention found on hubs. Routing between networks is a router function, and encryption and wireless access are separate roles.

Which two devices are most commonly used in a WAN environment? (Choose two.)
Select 2 answers.
Please select an optionIncorrectCorrect answer: B, C
In the context ofWide Area Networks (WANs), the key objective is to connect geographically separated networks using service provider infrastructure. The FLDTEC course emphasizes that WAN environments typically involve devices that can handle different physical transmission mediums and protocols. Modems: Modulate and demodulate analog signals to digital signals. Used in WAN environments to connect over analog lines like DSL or leased lines. Essential for interfacing between digital routers and analog telephone networks. Optical Fiber Converters: Also known asmedia converters, they are used to convert electrical signals to optical signals (and vice versa) for fiber transmission. Common in WAN scenarios where long-distance high-speed transmission over fiber is required. Incorrect Options: A. Hubs: Obsolete Layer 1 devices used in LANs, not suitable for WANs. D. Network Interface Cards (NICs): Used in end devices for LAN connectivity. E. Wireless Access Points: Typically used in WLANs within local premises, not WAN infrastructure. This aligns withCisco's WAN architecture fundamentalsas highlighted in FLDTEC under ??Cisco Equipment and Related Hardware.??
