Which of the following encryption modes is used in WAPI authentication?
Answer(s): B
WAPI (WLAN Authentication and Privacy Infrastructure) is a Chinese national standard for wireless security. Unlike the international WPA standards that use AES (CCMP) or the legacy TKIP, WAPI utilizes the SM4 (formerly SMS4) symmetric block cipher algorithm for data encryption and the SM3 hash algorithm for integrity. Huawei enterprise APs support WAPI to meet specific regulatory and security requirements in the Chinese market.
Which of the following technologies is used to improve air interface security?
Answer(s): D
PMF (Protected Management Frames), defined in the 802.11w standard, is the primary technology used to enhance security specifically over the air interface. While WDS is for bridging, andDTLS/IPsec are used for tunnel encryption (like CAPWAP), PMF protects management frames (such as Disassociation, Deauthentication, and Robust Action frames) from being forged or spoofed by attackers. This prevents common DoS (Denial of Service) attacks where an attacker forcibly disconnects legitimate users from the Wi-Fi network.
Which of the following packet priority queues are supported over the air interface?
Answer(s): A,B,C,D
Huawei’s air interface scheduling follows the WMM (Wi-Fi Multimedia) standard, which maps data packets into four Access Categories (ACs) to ensure Quality of Service (QoS). These queues are:VO (Voice): Highest priority for low-latency voice traffic.VI (Video): High priority for video streaming.BE (Best Effort): Standard priority for general data traffic.BK (Background): Lowest priority for non-time-critical tasks like file downloads or print jobs.
What types of attack detection are supported over the air interface?
Huawei’s WIDS (Wireless Intrusion Detection System) and WIPS (Wireless Intrusion Prevention System) provide comprehensive air interface protection. They are designed to detect:Flood attacks (A): Detecting an abnormal volume of management frames (like Auth/Deauth floods).Spoofing attacks (B): Detecting unauthorized APs or STAs using the MAC addresses of authorized devices.Weak IV attacks (C): Detecting attempts to exploit older encryption (like WEP) by identifying weak Initialization Vectors.Brute force cracking (D): Monitoring for repeated authentication failures that indicate an attempt to guess WPA/WPA2-PSK or WAPI-PSK keys.
NETCONF is based on the Extensible Markup Language (XML).
Answer(s): A
NETCONF (Network Configuration Protocol) is the primary management protocol used in the Xinghe Intelligent Campus solution for communication between iMaster NCE-Campus and network devices. It uses a multi-layer structure where the Content Layer (data) and Operations Layer are encoded in XML. This allows for a structured, hierarchical representation of configuration data and state information, making it more efficient and programmable than traditional CLI or SNMP.
