200-301 Question #955: Real Exam Question with Answer & Explanation

Question

What must be considered for a locally switched FlexConnect AP if the VLANs that are used by the AP and client access are different?

Options

• AThe APs must be connected to the switch with multiple links in LAG mode
• BThe switch port mode must be set to trunk
• CThe native VLAN must match the management VLAN of the AP
• DIEEE 802.10 trunking must be disabled on the switch port.

Explanation

For a FlexConnect AP to locally switch clients to different VLANs, the switch port connected to the AP must be configured as a trunk port to carry multiple VLANs.

Common mistakes.

• A. While LAG (Link Aggregation Group) can be used for redundancy and increased bandwidth, it's not a mandatory requirement specifically for a FlexConnect AP to handle different client VLANs via local switching.
• C. The native VLAN on the trunk port should typically match the management VLAN of the AP for untagged traffic, but configuring the port as a trunk is the fundamental requirement for carrying multiple client VLANs, not just native VLAN matching.
• D. IEEE 802.10 is an older standard for security in token ring networks and is irrelevant to modern Ethernet VLAN trunking (which uses 802.1Q).
