Your digital signal cannot transmit and receive data at the same time. Hosts use the CSMA/CD protocol to prevent collisions. The physical connection consists of one wire pair. All of the above What should you install when security is a main concern? Higher-quality cables Firewall DNS Switches You need to optimize network traffic by spreading it across multiple connections. Which strategy should be used? Load balancing Traffic shaping Add VLAN’s A 1Gbps connection Following the regulations One of the following network devices forwards the data it receives on a port to all other connected ports.

What type of cable do you need to use to connect the hub to the switch? EtherIP Crossover Straight-through Cable Sense, Multiple Access Which of the following are WAN protocols or technologies? (Choose all that apply.) ATM ISDN MPLS RIP Why do most switches run the Spanning Tree Protocol by default? It monitors how the network is functioning. It stops data from forwarding until all devices are updated. It prevents switching loops. It manages the VLAN database.
