  1. What is the purpose of a VLAN (Virtual Local Area Network)?

    Answer: To logically segment a physical network into separate broadcast domains

    VLANs logically divide a single physical switched network into multiple isolated broadcast domains, improving security, performance, and network management.

  2. What is the difference between an access port and a trunk port on a Cisco switch?

    Answer: An access port carries traffic for a single VLAN; a trunk port carries traffic for multiple VLANs using 802.1Q tagging

    An access port carries untagged traffic for a single VLAN (typically connected to end devices), while a trunk port carries tagged traffic for multiple VLANs using 802.1Q encapsulation.

  3. Which protocol does a Cisco router use by default to dynamically learn routes from other Cisco routers in an enterprise network?

    Answer: EIGRP

    EIGRP (Enhanced Interior Gateway Routing Protocol) is Cisco's proprietary advanced distance-vector routing protocol, commonly deployed by default in Cisco enterprise networks.

  4. What is the function of the Cisco IOS 'show interfaces' command?

    Answer: Displays interface status, error counters, speed, duplex, and traffic statistics

    The 'show interfaces' command displays detailed information about each interface including operational status, error counters, bandwidth, speed, duplex settings, and traffic statistics.

  5. What type of cable is required to directly connect two switches together without an uplink port?

    Answer: Crossover cable

    A crossover cable crosses the transmit and receive pairs, allowing two like devices (switch-to-switch) to communicate directly; modern switches with Auto-MDIX detect this automatically.

  6. Which Cisco feature automatically negotiates the correct cable type (straight-through or crossover) needed for a connection?

    Answer: Auto-MDIX

    Auto-MDIX (Automatic Medium-Dependent Interface Crossover) automatically detects and configures the correct transmit/receive pair orientation, eliminating the need for crossover cables.
