Explanation
128-bit AES (Advanced Encryption Standard) is the encryption standard that Cisco Ultra-Reliable Wireless Backhaul (CURWB) networks meet, making option C correct. AES-128 is a widely adopted, FIPS 140-2 compliant symmetric encryption standard that provides strong security for industrial and mission-critical wireless communications.
Options A (50AES), B (40AES), and D (100AES) are fabricated values - AES does not come in 40, 50, or 100-bit variants. The real AES key sizes are 128, 192, and 256 bits, so any other number is a red flag.
Memory tip: Think "1-2-8 = AES is great" - 128 is the baseline AES strength, and CURWB uses this standard to secure its high-reliability wireless links in harsh environments like transportation, utilities, and public safety.
