When a floating static route is configured, which action ensures that the backup route is used when the primary route fails?
The floating static route must have a higher administrative distance than the primary route so it is used as a backup
The administrative distance must be higher on the primary route so that the backup route becomes secondary.
The floating static route must have a lower administrative distance than the primary route so it is used as a backup
The default-information originate command must be configured for the route to be installed into the routing table
What benefit does controller-based networking provide versus traditional networking?
provides an added layer of security to protect from DDoS attacks
combines control and data plane functionality on a single device to minimize latency
moves from a two-tier to a three-tier network architecture to provide maximum redundancy
allows configuration and monitoring of the network from one centralized point
A Cisco IP phone receive untagged data traffic from an attached PC. Which action is taken by the phone?
It allows the traffic to pass through unchanged

It tags the traffic with the native VLAN
How do TCP and UDP differ in the way that they establish a connection between two endpoints？
TCP use the three-way handshake, and UDP dose no guarantee message delivery
TCP use synchronization packets, and UDP uses acknowledgement packets
UDP provides reliable message transfer, and TCP is a connectionless protocol.
UDP use SYN,SYN ACK, and FIN bits in the frame header while TCP uses SYN,SYN ACK, and ACK bis.
