10 A network administrator is designing the layout of a new wireless network. Which three areas of concern should be accounted for when building a wireless network? (Choose three.) mobility options extensive cabling coverage area* interference* packet collision security* 11 What is one main characteristic of the data link layer? It converts a stream of data bits into a predefined code. It shields the upper layer protocol from being aware of the physical

environmental controls (e.g.‚ air conditioning‚ fire suppression) and security devices. 1. Structured cabling and server room build up Structured cabling design and installation is governed by a set of standards that specify wiring data centers for data or voice communications using various kinds of cable‚ most commonly category 5e (CAT-5e)‚ category 6 (CAT-6)‚. These standards define how to lay the cabling in various topologies in order to meet the needs of the customer‚ typically using a central patch

(trunk) and a terminating resistor (terminator) at each end. Data communication message travels along the bus in both directions until it is picked up by a workstation or server NIC. If the message is missed or not recognized‚ it reaches the end of the cabling and dissipates at the terminator. Bus Network Topology requires a multipoint connection. All nodes on the bus topology have equal access to the trunk. This is accomplished using short drop cables or direct T-connectors. The number of devices and
