When a large enterprise deployed a wireless network, it adopted the Navi AC networking architecture to avoid potential security threats to the network caused by visitor data. Which of the following…

Question

Options

• ALocal AC and Navi AC do not support compatibility between different versions
• BRoaming groups cannot be established between Navi AC and Local AC
• CMake sure that the DTLS pre-shared key configuration of Local AC and Navi AC is consistent
• DDoes not support cross-Navi AC roaming

• A
  79% (15)
• B
  5% (1)
• C
  11% (2)
• D
  5% (1)

Explanation

Option A is the false statement because Navi AC and Local AC do support cross-version compatibility, meaning they can operate together even when running different software versions - so claiming they "do not support compatibility between different versions" is incorrect.

Option B is true: roaming groups in Navi AC architecture are established between Local ACs that share the same Navi AC, not directly between a Local AC and the Navi AC itself, so it is not a wrong point. Option C is also true: DTLS (Datagram Transport Layer Security) pre-shared keys must be consistent between Local AC and Navi AC to establish a secure tunnel, making it a valid and necessary deployment requirement. Option D is equally true: the Navi AC design intentionally limits roaming to within a single Navi AC domain, so cross-Navi AC roaming is not supported by design.

Memory tip: Think of the question as a "spot the myth" challenge - A is the only option describing a limitation that doesn't actually exist. A helpful mnemonic: "Versions Are Compatible" (VAC) - Navi AC is version-flexible, so any statement saying it isn't is your red flag.
