Introducing Cisco Data Center Networking (DCICN) — Question 48

When connecting a switch port to a virtualization host requiring 802.1q VLAN tagging, which spanning-tree port type should be configured on the switch?

Answer options

• A. normal
• B. edge
• C. edge trunk
• D. PortFast
• E. trunk

Correct answer: C

Explanation

The correct answer is C, 'edge trunk', because it allows for VLAN tagging while enabling rapid spanning-tree convergence. Options A and B are incorrect as they do not support trunking or VLAN tagging. Option D, 'PortFast', is used for access ports to skip the listening and learning states but does not apply to trunk configurations, while option E, 'trunk', does not specify the edge requirement needed in this scenario.
