VPC stands for Virtual Private Cloud, a virtual network dedicated to a user's account within a cloud environment.

• VPC allows users to create isolated sections of the cloud where they can launch resources like virtual machines, databases, and storage.

• Users can define their own IP address range, subnets, route tables, and network gateways within a VPC.

• VPC provides security by allowing users to control inbound and outbound...read more

HSRP (Hot Standby Router Protocol) and GLBP (Gateway Load Balancing Protocol) are protocols used in networking for providing redundancy and load balancing.

• HSRP is a Cisco proprietary protocol used for providing high availability by allowing two or more routers to work together in a group, with one router acting as the active router and the others as standby routers.

• GLBP is also a Cisco proprietary protocol that allows ...read more

The number of links that can be bundled in a port channel depends on the specific network equipment and configuration.

• The maximum number of links that can be bundled in a port channel varies depending on the network device and software.

• Commonly, network devices support bundling anywhere from 2 to 8 links in a port channel.

• Some high-end switches or routers may support even more links in a port channel, such as 16 or 32.

FlexConnect is a feature in Cisco wireless LAN controllers that allows access points to locally switch traffic instead of tunneling it back to the controller.

• FlexConnect allows access points to function even if they lose connection to the controller.

• It is useful for branch offices or remote locations where a direct connection to the controller may not be feasible.

• FlexConnect can improve network performance by reducing ...read more
