Network + N10-007 Part 2 Flashcards
SSH File Transfer Protocol (SFTP)
A replacement for FTP released after many of the inadequacies of SCP (such as the inability to see the files on the other computer) were discovered.
SSID Broadcast
A wireless access point feature that announces the WAP’s SSID to make it easy for wireless clients to locate and connect to it. By default, most WAPs regularly announce their SSID. For security purposes, some entities propose disabling this broadcast.
SSL SSL VPN
A type of VPN that uses SSL encryption. Clients connect to the VPN server using a standard Web browser, with the traffic secured using SSL. The two most common types of SSL VPNs are portal VPNs and SSL tunnel VPNs.
ST Connector
Fiber optic connector used primarily with 2.5mm, single mode fiber. It uses a push on, then twist to lock mechanical connection commonly called stick and twist although ST actually stands for straight tip.
Star Topolgy
A network topology in which all computers in the network connect to a central wiring point.
Star Bus Topology
A hybrid star and bus topologies that uses a physical star, where all nodes connect to a single wiring point (such as a hub) and a logical bus that maintains the Ethernet standards. One benefit of a star bus topology is fault tolerance.
Start Frame Delimiter (SFD)
One byte section of an Ethernet packet that follows the preamble and precedes the Ethernet frame.
Start of Authority (SOA) Record
DNS record that defines the primary name server in charge of the forward lookup zone.
Stateful (DHCP)
Describes a DHCPv6 server that works very similarly to an IPv4 server, passing out IPv6 addresses, subnet masks, and default gateways as well as optional items like DNS server addresses.
Stateful Filtering/Stateful Inspection
A method of filtering in which all packets are examined as a stream. Stateful devices can do more than allow or block; they can track when a stream is disrupted or packets get corrupted and act accordingly.
Stateless (DHCP)
Describes a DHCPv6 server that only passes out info like DNS servers’ IP addresses, but doesn’t give clients IPv6 addresses.
Stateless Filtering/Stateless Inspection
A method of filtering where the device that does the filtering looks at each OP packet individually, checking the packet for IP addresses and port numbers and blocking or allowing accordingly.
Statement of Work (SOW)
A contract that defines the services, products, and time frames for the vendor to achieve.
Static Addressing
The process of assigning IP addresses by manually typing them into client computers.
Static NAT (SNAT)
A type of Network Address Translation (NAT) that maps a single router’s routing table that are not updated by any automatic route discovery protocols. Static routes must be added, deleted, or changed by a router administrator. Static routes are the opposite of Dynamic Routes.
