Which of the following three best describes Enterprise Services? Common to all users Traffic crosses subnet/VLAN Traffic within the same subnet/VLAN Traffic always crosses the backbone Traffic may/may not cross the backbone 4 . Which of the following are true regarding Legacy Bridging and LAN Switching? Choose two. Legacy Bridging is software based and slower than LAN Switching Legacy Bridging is software based and faster that LAN Switching LAN Switching is software based LAN Switching is hardware based 5 . Which of the following switches support 10/100 Mbps ports? 1900 1910 2820 2900XL 6 . Which two attributes best describe access layer switches? Low cost InterVLAN routing Robust Layer 3 throughput High port density to connect end users to the network 7 . Your company has a large campus network including seven buildings interconnected with a high-speed, high-bandwidth backbone. A dual core configuration is necessary because redundant connections are required. You will be using a Catalyst 6000 series switch at the distribution layer. Which device would be the most desirable at the core layer? Catalyst 5500 series switch Catalyst 8500 series switch Catalyst 6000 series switch Catalyst 4000 series switch 8 . Where will you be taken on a Catalyst 5000 series switch if no password is configured? To a password prompt where you can choose a password To the first level of access in the switch – User mode You will be unable to access the switch Privileged mode 9 . Which of the following best describes a unicast frame? The destination MAC address field has a specified computer’s MAC The destination MAC address field contains FFFF.FFFF.FFFF The destination MAC address field has a special MAC address used by other computers running the same protocol Multiple interrupts are generated 10 . Which of the following three best describes Remote Services? Devices connected by switches Devices connected by routers Traffic crosses the subnet/VLAN Traffic always crosses the backbone Traffic may/may not cross the backbone 11 . With the traffic patterns moving towards the 20/80 rule, which of the following is true? Network Layer 2 performance must be better than Network Layer 3 performance Network Layer 3 performance must be better than Network Layer 2 performance Network Layer 3 performance should at least match Network Layer 2 performance Network Layer 2 performance must be worse than Network Layer 3 performance 12 . Which “set based” command is used to erase a parameter? set disable show clear delete set set clear 13 . You can remove or replace line modules without powering off a Catalyst 5000. True False 14 . With the 4000/5000/6000 series of switches, what are the three sets of commands that comprise close to 90% of the commands executed on the switch? Choose three. set show clear delete 15 . Which of the following best describes Layer 4 switching? Layer 4 hardware-based routing that considers the application Layer 2 hardware-based routing that considers the application Layer 3 hardware-based routing that considers the application Layer 4 hardware-based switching that considers the application 16 . Read and answer the question A B C D 17 . Which of the following best describes a multicast frame? The destination MAC address field has a specified computer’s MAC address The destination MAC address field has FFFF.FFFF.FFFF The destination MAC address field has a special MAC address used by other computers running the same protocol Only one interrupt is generated 18 . Your company has experienced 300 percent growth over the last year and has recently installed a new multimedia center for distributing company information throughout the campus. Your company has requirements for gigabit-speed data transfer, high availability, and inter-VLAN routing between the end users and the enterprise server farms. What is the most appropriate device for the distribution layer? Catalyst 1900 series switch with (12) 10BaseT ports Catalyst 4000 series switch with a 6-port Gigabit Ethernet module Catalyst 6000 series switch with a 16-port Gigabit Ethernet module Catalyst 8500 series switch 19 .
