Term 871
Static route
A static route is a manually configured path in a router's routing table that tells the router exactly where to send packets for a specific destination network.

Term 871
A static route is a manually configured path in a router's routing table that tells the router exactly where to send packets for a specific destination network.
Term 872
A step scaling policy is a type of auto scaling rule that adjusts the number of computing resources in predefined increments based on the magnitude of a CloudWatch alarm breach.
Term 873
Sticky MAC address is a switch security feature that dynamically learns and remembers a device’s MAC address on a specific port to prevent unauthorized devices from connecting.
Term 874
A Storage Area Network (SAN) is a dedicated, high-speed network that provides block-level storage access to servers, making storage appear as if it is directly attached to the server.
Term 875
A storage class is a category of data storage that defines how data is stored, accessed, retrieved, and billed in a cloud environment.
Term 876
A storage controller is a hardware or software component that manages how data is stored, accessed, and organized on storage devices like hard drives, SSDs, or cloud storage volumes.
Term 877
Storm control is a network feature that limits the amount of broadcast, multicast, or unknown unicast traffic on a switch port to prevent network disruptions.
Term 878
Shielded Twisted Pair (STP) is a copper cable that wraps each twisted pair in foil or braid to block electromagnetic interference.
Term 879
STP (Spanning Tree Protocol) is a network protocol that prevents loops in Ethernet networks by creating a loop-free logical topology.
Term 880
STP convergence is the process by which a network of switches using the Spanning Tree Protocol reaches a stable, loop-free topology after a change in the network.
Term 881
A Straight Tip Connector, often called an ST connector, is a fiber optic cable connector that uses a twist-on bayonet-style coupling mechanism to securely attach a fiber optic cable to a device or patch panel.
Term 882
A straight-through cable is a type of Ethernet cable where the wire arrangement is identical on both ends, used to connect different types of network devices, like a computer to a switch.
Term 883
Stream Control Transmission Protocol (SCTP) is a transport layer protocol that combines the reliability of TCP with the speed of UDP and adds the ability to send multiple independent streams of data over a single connection.
Term 884
A subinterface is a virtual interface created on a single physical network interface to allow it to carry multiple VLANs or logical networks separately.
Term 885
A subnet is a logical subdivision of an IP network, created by partitioning a larger network address space using subnet masks.
Term 886
A subnet mask is a 32-bit number that helps a computer or network device determine which part of an IP address identifies the network and which part identifies the host device on that network.
Term 887
Subnetting is the process of dividing a larger IP network into smaller, more manageable subnetworks (subnets) to improve performance, security, and efficient use of IP addresses.
Term 888
A Subscriber Connector (SC) is a fiber optic cable connector known for its push-pull coupling mechanism and square shape, commonly used in data centers and telecommunications for single-mode and multimode fiber connections.
Term 889
In EIGRP, a successor is the primary next-hop router chosen to forward packets to a destination network, determined by having the highest feasibility and lowest metric.
Term 890
Sustainability in IT refers to designing, operating, and disposing of technology systems in a way that minimizes environmental impact and promotes long-term resource efficiency.
Term 891
The Sustainability pillar is a framework within cloud architecture that focuses on minimizing environmental impact, reducing energy consumption, and optimizing resource usage across IT operations.
Term 892
A Switch Virtual Interface (SVI) is a logical, software-based interface on a multilayer switch that provides Layer 3 routing capabilities for a VLAN, allowing devices in different VLANs to communicate without an external router.
Term 893
A switch is a networking device that connects devices on a local area network and uses MAC addresses to forward data only to the intended recipient.
Term 894
A logical interface on a network switch that allows it to be managed and communicate with other devices using IP addresses.
Term 895
A Switched Port Analyzer (SPAN) is a feature on network switches that copies traffic from one or more ports to a monitoring port for analysis.
Term 896
A virtual interface on a Layer 3 switch that allows that switch to route traffic between VLANs without needing a separate router.
Term 897
A switchport is a physical or virtual interface on a network switch that connects devices like computers, printers, or other switches to a local area network.
Term 898
Symmetric encryption is a cryptographic method where the same secret key is used to both encrypt and decrypt data, ensuring confidentiality between two parties.
Term 899
Synchronization is the process of making sure two or more systems, devices, or pieces of data stay exactly matched and up-to-date with each other.
Term 900
Syslog is a standard protocol used to send and store log messages from network devices and servers to a central logging server for monitoring and troubleshooting.
