For the aggregation layer, you must configure two new HPE Aruba Networking CX 6200M (VSF)...

To answer this correctly, it is vital to distinguish between VSF (Virtual Switching Framework) and VSX (Virtual Switching Extension) .

VSF (Virtual Switching Framework) Logic: The CX 6200 and 6300 series use VSF to form a " stack. " In a VSF stack, multiple physical switches operate as a single logical device with a single control plane and a single configuration file.

LAG Configuration in VSF: Because a VSF stack is a single logical entity, creating a Link Aggregation Group (LAG) that spans multiple members is handled exactly like a standard LAG on a single switch. You simply create the interface lag X and then assign physical ports from different members (e.g., member 1 and member 2) to that same LAG ID.

The " multi-chassis " Keyword: The keyword multi-chassis (seen in Options B and D) is specific to VSX , which is used on high-end switches like the CX 6400 and 8000 series. VSX involves two separate control planes that synchronize information. In VSX, you must use the multi-chassis command to let the switches know the LAG is split across two different chassis. In VSF, this keyword is not used and would result in a syntax error on a 6200 switch.

Analyzing the Options:

Option A (Correct): It uses standard interface lag 1 syntax. It assigns port 1/1/1 (from member 1) and port 2/1/1 (from member 2) to the same LAG. This perfectly fulfills the requirement for redundant ports from both switches in a VSF stack.

Option B: Incorrect because it uses the multi-chassis keyword (VSX only).

Option C: Incorrect because it only configures a port from one switch (1/1/1), failing the requirement for redundancy across both switches.

Option D: Incorrect because it uses the multi-chassis keyword (VSX only).

Key Takeaway for the ACP-S Exam: * VSF (6200/6300) = Standard LAG configuration across members.

VSX (6400/8000) = Requires multi-chassis keyword under the LAG interface.
