______________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 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
