The WS-C3750G-12S-E Cisco Catalyst 12 Ports Managed Switch offers various High Availability (HA) and redundancy options to ensure that the network remains up and running in the event of a failure. These options include:

• StackWise technology: This technology allows multiple switches to be stacked together and managed as a single logical switch. This provides redundancy in case of a switch failure and increases the available ports.
• Hot-Standby Router Protocol (HSRP): This protocol allows for the configuration of a virtual IP address shared between multiple routers. This virtual IP address is used as the default gateway for hosts on the network, and if the active router fails, the standby router takes over, providing redundancy.
• Link Aggregation Control Protocol (LACP): This is a standard protocol used to bundle multiple physical links together to form a logical link, providing redundancy and increasing the available bandwidth.
• Rapid Spanning Tree Protocol (RSTP): This protocol ensures that only one active path exists between two network devices, providing redundancy and preventing loops in the network.
• Virtual Router Redundancy Protocol (VRRP): This protocol allows for the configuration of a virtual router that is shared between multiple physical routers. The virtual router acts as the default gateway for hosts on the network, and if the active router fails, the standby router takes over, providing redundancy.

All those features allow network administrators to increase the availability and redundancy of the network, ensuring that the network remains up and running in the event of a failure, improving the network's resilience, and reducing the risk of network downtime.

The WS-C3750G-12S-E Cisco Catalyst 12 Ports Managed Switch offers various network scalability and flexibility options to allow network administrators to easily expand and adapt the network as needed. These options include:

• StackWise technology: This technology allows multiple switches to be stacked together and managed as a single logical switch. This increases the number of available ports and allows for easy expansion of the network as more devices are added.
• StackPower: This technology allows power to be shared among multiple switches in a stack, making it easy to add new switches to the network without the need for additional power supplies.
• VLANs: Virtual LANs (VLANs) can be used to segment the network into multiple logical networks, allowing for greater flexibility and security. This allows for the creation of separate networks for different departments or teams, reducing the risk of network congestion and increasing the security of the network.
• Quality of Service (QoS): This feature allows for the prioritization of different types of network traffic, ensuring that critical applications and services receive the necessary bandwidth. This allows for better scalability and flexibility as the network grows and changes.
• FlexStack Plus: This technology allows for the stacking of switches with different numbers of ports, providing flexibility for network expansion and allowing for a mix of different switch models in the stack.

All those features allow network administrators to easily expand and adapt the network as needed, ensuring that the network can grow and change with the organization's needs, improving network scalability and flexibility.
