What is firmware?
This is stored in Random Access Memory (RAM). It reflects the current configuration.
What is the running-config?
Enable routers to exchange route information, compare path information, and then to select the best path to the destination network. Examples include Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP).
What are routing protocols?
This network is easy to setup, less complex, lower cost, and allows simple file sharing.
What is a peer-to-peer network?
Reserved circuits within the service provider’s network that connect geographically separated offices for private voice and/or data networking. The circuits are rented at a monthly or yearly rate.
What are Dedicated Leased Lines?
A physical management port that provides out-of-band access to a Cisco device. Out-of-band access refers to access via a dedicated management channel that is used for device maintenance purposes only.
This default virtual interface lets you remotely manage a switch over a network using IPv4 and IPv6. Each switch comes with one SVI appearing in the default configuration "out-of-the-box."
What is VLAN1?
The most relevant and common protocol suite used today.
What is Internet Protocol Suite or TCP/IP?
A LAN switch, router, and firewall appliance are examples of these devices.
What are intermediary devices?
These networks are capable of delivering data, voice, and video between many different types of devices over the same network infrastructure. This network infrastructure uses the same set of rules, agreements, and implementation standards.
What are converged networks?
PuTTY, Tera Term, and Secure CRT are examples of these.
What are Terminal Emulation Programs?
The process of converting information into another acceptable form, for transmission.
What is Encoding?
The 4 layers the TCP/IP protocol suite.
What are the Application, Transport, Internet and Network Access layers?
This diagram illustrates devices, ports, and the addressing scheme of the network.
What is a logical topology?
Having multiple paths to a destination.
What is redundancy?
This mode is identified by a prompt that ends with (config)# after the device name, such as Switch(config)#
What is global configuration mode?
The process of managing the rate of data transmission.
What is Flow Control?
This layer provides for common representation of the data transferred between application layer services.
What is Layer 6 Presentation?
A network infrastructure that provides access to other networks over a wide geographical area, which is typically owned and managed by a larger corporation or a telecommunications service provider.
What is a Wide Area Network (WAN)?
A primary mechanism for managing congestion and ensuring reliable delivery of content to all users.
What is Quality of Service (QoS)?
All-purpose break sequence used to abort DNS lookups, traceroutes, pings, etc.
What is Ctrl-Shift-6?
Information is being transmitted to a one or more end devices.
What is Multicast?
The process used by a receiving device to remove one or more of the protocol headers.
