Networking Principles Flashcards
Which of the following allows its users on a less secure network to send and receive data through a safe connection by extending a private network across the Internet?
Wide Area Network - WAN
Virtual Private Network - VPN
Virtual Local Area Network - VLAN
Wireless Local Area Network - WLAN
A Virtual Private Network - VPN allows its users on a less secure network to send and receive data through a safe connection by extending a private network across the Internet.
Which of the following can be found in various Extron Pro Series control processors for communication to external supported devices, such as TouchLink Pro touchpanels and user interfaces?
VLAN port
LAN port
AV VPN port
AV LAN port
AV LAN ports are available in various Extron control processors for communication to external supported devices, such as TouchLink Pro touchpanels and user interfaces.
Which of the following is manually configured as a fixed address for a device, and does not change?
Transmission Control Protocol - TCP
Static IP Address
User Datagram Protocol - UDP
Dynamic IP Address
Static IP Addresses are manually configured as a fixed address for a device, and does not change.
Which of the following can be used as an intermediate router for the subnet when an IP address is not within the network?
DHCP Server
Default Gateway
MAC Address
Subnet Mask
A Default Gateway is used as an intermediate router for the subnet when an IP address is not within the network.
Which of the following layers of the OSI Model handles error detection with CRC checksums and flow control on a local network?
Transport Layer 4
Physical Layer 1
Network Layer 3
Data Link Layer 2
The Data Link Layer 2 handles error detection CRC checksums and flow control on a local network.
Within the OSI Model which layer allows for varying operating systems to communicate with each other on the network?
Session Layer 5
Transport Layer 4
Presentation Layer 6
Application Layer 7
The Presentation Layer 6 allows for computers with Microsoft Windows, macOS, and Linux to communicate with each other on a network.
Which of the following relationships describes the basic network operations of sending and receiving bidirectional data messages?
Client-Server
Peer-to-Peer
Wireless-Wired
Switcher-Router
The basic network operations of sending and receiving bidirectional data messages is a Client-Server relationship.
Which one of the following network topologies connects a central node to every device on the network, acting as a multiport repeater?
Star Topology
Mesh Topology
Bus Topology
Tree Topology
The Star network topology connects a central node to every device on the network, acting as a multiport repeater.
Which one of the following supports communication between subnets and across different networks, by determining the next network point to which a packet is forwarded as its destination?
Workstations
Servers
Routers
Switches
Routers support communication between subnets and across different networks, by determining the next network point to which a packet is forwarded as its destination.
