Question

As part of a new wireless implementation, the Chief Information Officer's (CIO's) main objective is to immediately deploy a system that supports the 802.11r standard, which will help wireless VoIP devices in moving vehicles. However, the 802.11r standard was not ratified by the IETF. The wireless vendor's products do support the pre-ratification version of 802.11r. The security and network administrators have tested the product and do not see any security or compatibility issues; however, they are concerned that the standard is not yet final. Which of the following is the BEST way to proceed?

Options

  • APurchase the equipment now, but do not use 802.11r until the standard is ratified.
  • BDo not purchase the equipment now as the client devices do not yet support 802.11r.
  • CPurchase the equipment now, as long as it will be firmware upgradeable to the final 802.11r standard.
  • DDo not purchase the equipment now; delay the implementation until the IETF has ratified the final 802.11r

Why each option

The question tests how to balance an immediate wireless deployment requirement against the risk of deploying a pre-ratified standard that may change before finalization.

APurchase the equipment now, but do not use 802.11r until the standard is ratified.

Purchasing equipment and then not using 802.11r until ratification defeats the CIO's primary objective of immediately supporting wireless VoIP for devices in moving vehicles.

BDo not purchase the equipment now as the client devices do not yet support 802.11r.

The scenario explicitly states that testing revealed no compatibility issues, so the premise that client devices do not yet support 802.11r is contradicted by the given facts.

CPurchase the equipment now, as long as it will be firmware upgradeable to the final 802.11r standard.Correct

Purchasing firmware-upgradeable equipment satisfies the CIO's requirement for immediate deployment while directly mitigating the risk that the final 802.11r standard may differ from the pre-ratification version. If the standard changes upon ratification, a firmware update aligns the deployed equipment without requiring a full hardware replacement. This approach balances operational urgency with long-term investment protection.

DDo not purchase the equipment now; delay the implementation until the IETF has ratified the final 802.11r

Delaying the entire implementation until IETF ratification directly contradicts the CIO's stated objective of immediate deployment and ignores the positive results from security and compatibility testing.
