An administrator is replacing a wireless router.
The configuration of the old wireless router was not documented before it stopped functioning.
The equipment connecting to the wireless network uses older legacy equipment that was manufactured prior to the release of the 802.11i standard.
Which of the following configuration options should the administrator select for the new wireless router?

A. B. C. D.C.
The 802.11i standard provides enhanced security mechanisms for wireless networks. The standard defines two encryption protocols: Temporal Key Integrity Protocol (TKIP) and Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP).
TKIP was created as a temporary solution to replace Wired Equivalent Privacy (WEP) until CCMP was standardized. TKIP uses a per-packet key that is derived from a master key and a packet sequence number. It provides message integrity, authentication, and confidentiality. However, TKIP is vulnerable to some attacks and has been deprecated.
CCMP is a more secure encryption protocol that is based on the Advanced Encryption Standard (AES). It provides message confidentiality, integrity, and authentication. CCMP is the encryption protocol recommended by the 802.11i standard.
Based on the scenario, the equipment connecting to the wireless network uses older legacy equipment that was manufactured prior to the release of the 802.11i standard. This suggests that the legacy equipment may not support CCMP encryption. Therefore, the administrator should select an encryption protocol that is compatible with the legacy equipment.
WPA and WPA2 are two security protocols that are designed to work with the 802.11 wireless standard. WPA2 is the more secure protocol and is recommended by the 802.11i standard.
WPA+TKIP and WPA2+TKIP use the TKIP encryption protocol, which is compatible with legacy equipment. WPA+CCMP and WPA2+CCMP use the CCMP encryption protocol, which may not be compatible with legacy equipment.
Therefore, the best configuration option for the new wireless router in this scenario would be WPA+TKIP (option C), as it provides both compatibility with legacy equipment and some level of security.
