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
- DDo not purchase the equipment now; delay the implementation until the IETF has ratified the

Explanation
Purchasing firmware-upgradeable equipment is the optimal risk-balanced decision. The CIO has an immediate operational need (802.11r for VoIP in moving vehicles), testing has confirmed no current security or compatibility issues, and the vendor supports the pre-ratification standard. Buying firmware-upgradeable hardware ensures that when IEEE finalizes 802.11r, the equipment can be updated to full compliance without hardware replacement - protecting the investment and eliminating the interoperability risk. Option A wastes the purchase by not using the primary feature needed. Option B is based on a false assumption - the question states no compatibility issues were found. Option D conflicts with the CIO's directive to deploy immediately and is unnecessary since testing showed no security concerns; the only outstanding issue is the standard's finalization, which firmware upgrades will address.
