Refer to the exhibit. CCNA.com has the industrial network shown in the exhibit. All switches are configured as layer 2 switches and are using VLAN 1 as their management VLAN. Each VLAN 1 interface…

Question

Exhibit

Options

• Aallows connectivity between the VLAN 1 interface on SW-C and other devices in the network.
• Ballows connectivity between Host A and other devices in the network.
• Callows connectivity between Host B and other devices in the network.
• Dallows the switch to pass traffic between Host A and Host B

• A
  93% (37)
• B
  3% (1)
• D
  5% (2)

Explanation

Assigning a default gateway to a Layer 2 switch only affects the switch's own management traffic - specifically, it enables the switch's VLAN 1 SVI (management interface) to communicate with devices on remote networks or subnets, such as when an admin SSHes into SW-C from a different network segment. Option A is correct because without a default gateway, the switch can reach devices on its own local subnet but cannot send or receive management traffic beyond that subnet.

B and C are wrong because hosts derive their own routing behavior from their own individually configured default gateways - the switch's gateway setting has zero effect on how Host A or Host B reach remote destinations. D is wrong because Layer 2 switches forward traffic between hosts using MAC address tables, which requires no default gateway at all; the gateway only matters for traffic originating from the switch itself, not traffic transiting through it.

Memory tip: Think of the switch's default gateway as its own "personal exit door" - it only helps the switch get out of the local subnet for management purposes, and has nothing to do with how connected hosts or forwarded frames behave.
