CCNA 200-301 exam questions/review (updated 2023) verified answers to pass!What is the IEEE of Bluetooth? 802.15 WPAN What is WiMAX and it IEEE? -Worldwide Interoperability for Microwave Access -IEEE 802.16 WWAN In cellular broadband there are two types of cellular networks, what are they? Global System for Mobile (GSM) and Code Division Multiple Access (CDMA). GSM is internationally recognized, while CDMA is primarily used in the US. Typically, it is used by rural homeowners and businesses where cable and DSL are not available. It is usually more expensive and requires a clear line of sight. Satellite Broadband What is the 802.11 WLAN? WiFi/wireless devices are based on IEEE 802.11 set of protocols and wireless local area network (WLAN) Wi-Fi computer communication in various frequencies -Radio frequency is 2.4 GHz What is the 802.11a? 5 Ghz frequency band IEEE standard for transmitting data over a wireless network. What are the two allocated radio frequency in 802.11 wireless LANs? 2.4GHz and 5GHz Which 802.11 standards exclusively use the 5 GHz radio frequency? 802.11a 802.11ac Which of the wireless networks typically uses lower powered transmitters for short ranges? WPAN In wireless, what does AP stand for? Access Point What does SSID stand for? shared service set identifier (SSID) The wireless router advertises its wireless services by sending ______________containing its shared service set identifier (SSID) Beacons What does QoS stand for and what does it do? Quality of Service is a feature of routers and switches which prioritizes traffic so that more important traffic can pass first. What does WAP stand for and what is it exactly? Wireless Access Point more generally just an access point, is a networking hardware devices that allows other Wi-Fi devices to connect to a wired network. What does Wi-Fi stand for? Wireless Fidelity technically, this is not the case. Wi-Fi is simply a trademarked term meaning IEEE 802.11x. What is an Autonomous AP? -Standalone devices like a home router. Where the entire WLAN configuration resides on the device. -Sometimes called thick APs -do not require a controller to control the AP and it use WLSE for management software -use for a network that requires only a couple of access points. What does WLC stand for? Wireless LAN Controller What does AS stand for? Autonomous System What are Controller-based APs? -These devices require no initial configuration and are often called lightweight APs (LAPs). -Also called thin APs -Centralized management, configuration, encryption, updates and policy settings through a centralized controller LAPs Lightweight Access Points LWAPP Light Weight Access Point Protocol What is another name for LAPs? Controller-based APs LAG Link Aggregation Group What is MIMO? Multiple Input Multiple Output. Uses multiple antennas to increase available bandwidth for IEEE 802.11n/ac/ax wireless networks. Up to eight transmit and receive antennas can be used to increase throughput. Which of the following components are integrated in a wireless home router? -Access Point -Switch -Router -Range Extender Access Point, Switch, Router
