Which three configurations are essential for setting up remote management access on a new Cisco switch?

• A. IP address, VTY lines, Subnet mask
• B. IP address, VTY lines, Default gateway
• C. Management IP, Console lines, Default gateway
• D. IP address, FastEthernet lines, DHCP settings

Answer: (B)

To enable remote management access on a Cisco switch, establishing the IP address, configuring VTY (Virtual Terminal) lines, and setting up a default gateway are crucial components. The IP address configuration allows the switch to be identifiable and reachable within a network. Without an IP address, remote devices cannot communicate with the switch, preventing remote management. VTY lines are essential for configuring remote access to the switch via protocols such as SSH or Telnet. These lines define the number of simultaneous remote management connections that can be made to the switch, enabling users to login and manage the switch settings remotely. The default gateway is necessary for packets destined for other networks to be routed correctly. If a remote management request originates from a different subnet, the switch must know where to send packets that should leave its local subnet. The default gateway serves this purpose, allowing the switch to communicate beyond its local network. In summary, an IP address makes the switch reachable, VTY lines facilitate remote access, and a default gateway enables communication with devices outside the local network, all of which are fundamental for managing a Cisco switch remotely.
