1. What is characteristic of how a hub operates?
• A hub selectively drops packets that represent potential security risks.
• A hub forwards data out all interfaces except the inbound interface.
• A hub dynamically learns the interfaces to which all devices are attached.
• At start up, a hub queries the devices on all interfaces in order to learn the MAC addresses of the attached devices.
• A hub transmits a frame to a specific interface based on the destination MAC address.

• crossover
• rollover
• straight-through
• patch
13. Refer to the exhibit. A technician measured the lengths of the CAT 5e structured cable runs in the exhibit. How should the technician evaluate the cabling shown in the diagram to the network administrator?
• All cabling to work areas are within specifications.
• Station A and B may experience intermittent problems because the length exceeds the recommended standard.
• Station B may experience intermittent problems because the length exceeds the recommended standard.
• Station C may experience intermittent network connectivity because the length is less than the recommended standard
• Station A and B will have intermittent problems because the length exceeds the recommended standard.
• Station C will not have network connectivity because the length is less than the recommended standard.
