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 netw ... orks, 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.

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 What is infrastructure mode in WLAN? A wireless router or AP connects wireless clients to a wired distribution system. What is API and what does the acronym stand for as well? Application Programming Interface (API) An API is software that allows other applications to access its data or services. It is a set of rules describing how one application can interact with another, and the instructions to allow the interaction to occur. Data formats shared between smart devices often use an Application Programming Interface (API There are four types of web service APIs Simple Object Access Protocol (SOAP) Representational State Transfer (REST) eXtensible Markup Language-Remote Procedure Call (XML-RPC) JavaScript Object Notation-Remote Procedure Call (JSON-RPC) Software-Defined Networking (SDN) is what? The physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices. dynamic, manageable, cost-effective, and adaptable What is FTP and it port number? File Transfer Protocol Port 20, 21 Provides reliability when loading an IOS image upon boot up What is SSH and it port number? Secure Shell Protocol port 22 What is telnet port number? 23 SMTP (Simple Mail Transfer Protocol) and port number port 25 DNS (Domain Name System) port number 53 HTTP (Hypertext Transfer Protocol) port number 80 SNMP (Simple Network Management Protocol) port number 161 What portocols are reliable, connection oriented and use TCP? FTP, SSH, Telnet, SMTP, DNS, HTTP, POP3, NTP, IMAP4, HTTPS What protocols are unreliable, connectionless and use UDP? DNS, DHCP, TFTP, SNMP What is DHCP? A protocol used to automate the assignment of IP Address. It stands for Dynamic Host Control Protocol and is the successor to BOOTP. DHCP port number 67 What is HSRP? HSRP stands for Hot Standby Router Protocol, it was designed for gateway redundancy without addition config on end devices. Routers configured with HSRP present themselves as a single virtual default gateway. -It is Cisco Proprietary -has one active router and one standby router What does VRRP stand for? Virtual Router Redundancy Protocol Has one master router and multiple backup routers What is VRRP virtual MAC address? 0000.5E00.01xx 0000.5E00.01xx, where xx is the value ID for the VRRP group number What is FHRP? First-Hop Redundancy Protocol In show ip route command, what letter represents EIGRP? D In show ip route command, what letter represents OSPF? O In show ip route command, what letter represents directly connected routes? C In show ip route command, what letter represents static route? S In show ip route command, what letter/symbol represents default routes? * on a route such as S * 0.0.0.0/0 [1/0] via Fastethernet 0/1 In show ip route command, what letter represents local/host connected directly connected? L What is PAgP? Port Aggregation Protocol is a Cisco proprietary link aggregator protocol that can bundle up to 8 active ports. -Only uses DESIRABLE and AUTO modes By default the maximum time that a Cisco switch will retain LLDP info before discarding it when it is enabled on an interface is ______ 120 seconds By default, a cisco switch will send LLDP advertisements every ____ seconds when LLDP is enabled on an interface 30 What is LLDP on a Cisco switch? Link Layer Discovery Protocol. OSI layer 2 open standard discovery protocol that is used to facilitate interoperability between Cisco devices and non-Cisco devices. Attributes that can be learned from neighboring devices contain Type, Length, Value (TLV) info including port description, system description and management address. What is VTP? VLAN Trunking Protocol (VTP) is a Layer 2 messaging protocol that maintains VLAN configuration consistency throughout a common administrative domain by managing VLAN additions, deletions, and name changes across multiple switches. Without VTP, you would have to manually add VLAN information to each switch in the network. What is CDP? Cisco Discovery Protocol (CDP) is a Cisco Proprietary feature that allows you to see directly connected Cisco devices. CDP can provide VLAN Trunking Protocol (VTP) information whereas LLDP does not. What is FlexConnect? Software basically. (previously known as Hybrid Remote Edge Access Point or H-REAP) is a wireless solution for branch office and remote office deployments. It enables customers to configure and control access points (AP) in a branch or remote office from the corporate office through a wide area network (WAN) link without deploying a controller in each office. The FlexConnect access points can switch client data traffic locally and perform client authentication locally when their connection to the controller is lost. When they are connected to the controller, they can also send traffic back to the controller. In the connected mode, the FlexConnect access point can also perform local authentication.
