LAN switches are interconnected? One collision domain exists per switch. The broadcast domain expands to all switches. Frame collisions increase on the segments connecting the switches. There is one broadcast domain and one collision domain per switch. The broadcast domain expands to all switches. Fill in the blank. A local law firm is redesigning the company network so that all 20 employees can be connected to a LAN and to the Internet. The law firm would prefer a low cost and easy solution for the project. What type of switch should be selected? fixed configuration StackWise stackable configuration StackPower modular configuration What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames? (Choose two.) path cost destination MAC address ingress port egress port destination IP address destination MAC address ingress port Which network device can serve as a boundary to divide a Layer 2 broadcast domain? access point router Ethernet bridge Ethernet hub Which type of address does a switch use to build the MAC address table? destination MAC address destination IP address source MAC address source IP address What is a definition of a two-tier LAN network design? access, distribution, and core layers collapsed into one tier, with a separate backbone layer distribution and core layers collapsed into one tier, and the access layer on a separate tier access and distribution layers collapsed into one tier, and the core layer on a separate tier access and core layers collapsed into one tier, and the distribution layer on a separate tier distribution and core layers collapsed into one tier, and the access layer on a separate tier Which two previously independent technologies should a network administrator attempt to combine after choosing to upgrade to a converged network infrastructure? (Choose two.) scanners and printers mobile cell phone traffic user data traffic electrical system VoIP phone traffic user data traffic VoIP phone traffic What is a basic function of the Cisco Borderless Architecture distribution layer? aggregating Layer 3 routing boundaries aggregating all the campus blocks acting as a backbone providing access to end user devices aggregating Layer 3 routing boundaries A network designer must provide a rationale to a customer for a design which will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice? (Choose two.) simpler deployment for additional switch equipment less required equipment to provide the same performance levels easier to provide redundant links to ensure higher availability reduced cost for equipment and user training lower bandwidth requirements simpler deployment for additional switch equipment easier to provide redundant links to ensure higher availability What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.) to create more broadcast domains to enhance user bandwidth to create fewer collision domains to isolate traffic between segments to isolate ARP request messages from the rest of the network to eliminate virtual circuits to enhance user bandwidth to isolate traffic between segments What is one function of a Layer 2 switch? determines which interface is used to forward a frame based on the destination MAC address forwards data based on logical addressing duplicates the electrical signal of each frame to every port learns the port assigned to a host by examining the destination MAC address determines which interface is used to forward a frame based on the destination MAC address Which network device can be used to eliminate collisions on an Ethernet network? switch hub router firewall A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic? Replace at least half of the switches with hubs to reduce the size of the broadcast domain. Add more switches so that fewer devices are on a particular switch. Segment the LAN into smaller LANs and route between them. Replace the switches with switches that have more ports per switch. This will allow more devices on a particular switch. Segment the LAN into smaller LANs and route between them. What does the term "port density" represent for an Ethernet switch? the number of available ports the numbers of hosts that are connected to each switch port the memory space that is allocated to each switch port the speed of each port the number of available ports What is the destination address in the header of a broadcast frame? 0.0.0.0 255.255.255.255 FF-FF-FF-FF-FF-FF 11-11-11-11-11-11 How can you eliminate collisions on an Ethernet network?Since 1990, the way to avoid collisions in an Ethernet is to use an Ethernet switch. The switch accepts a frame from an attached device, even while receiving frames from other devices and while transmitting to devices. When the destination port becomes non-busy, the switch sends it out to the destination.
How is a collision determined on an Ethernet network?Ethernet uses Carrier Sense Multiple Access/ Collision Detect (CSMA/CD) as its method of allowing devices to "take turns" using the signal carrier line. When a device wants to transmit, it checks the signal level of the line to determine whether someone else is already using it.
What causes collisions on network?A network collision occurs when two devices attempt to transmit data on a shared circuit. In a shared circuit where multiple devices are listening, only a single device can transmit data at a single point in time which requires the rest of the devices to be listening to the transmission.
Which solution would help a college alleviate network congestion due to collision?Which solution would help a college alleviate network congestion due to collisions? Switches provide microsegmentation so that one device does not compete for the same Ethernet network bandwidth with another network device, thus practically eliminating collisions.
