1 Which of the following are requirements of LAN design? (Choose three.)*** adaptability*** manageabilityoperability*** scalabilitystability2 When designing a LAN, at which layer of the OSI model does the process of segmenting collision domains occur?Layer 1*** Layer 2Layer 4Layer 73 Which of the following affect network availability? (Choose three.)*** throughput*** response timeworkstation speed*** access to resourcesdesktop applications4 What type of cabling is specified by TIA/EIA standards for interconnection of Intermediate and Main Distribution Facilities?patch cables of variable lengthshorizontal cross-connect cabling*** vertical cross-connect cablingparallel cross-connect cabling5 Which of the following are features of the access layer of the hierarchical network design model? (Choose two.)inter-VLAN routing*** Layer 2 filteringLayer 3 filtering*** microsegmentationbandwidth security6 A distribution layer switch operates at which OSI layers? (Choose two.)access*** data link*** networkinternettransport7 Which layer of the hierarchical network design model is often referred to as the backbone?accessdistributionnetwork*** coreworkgroupWAN8 At which layer of the hierarchical design model do users connect to the network?application*** accessdistributionnetworkcore9 Which hierarchical design model layer is responsible for containing network problems to the workgroups in which they occur?applicationaccess*** distributionnetworkcore10 Which of the following are characteristics of the core layer of the hierarchical network design model? (Choose three.)*** redundant pathshigh-level policy enforcementpacket manipulationmedia transitions*** rapid forwarding of traffic*** no packet filtering11 What is the primary reason for implementing security and policy routing at the distribution layer?filtering of core switching errors*** preventing policy and security issues from burdening the core layerpreventing unnecessary security policy decisions from burdening the access layermaintaining a consistent three-layer security policyisolating the access layer from traffic destined for other networks12 A major network upgrade that was designed to improve speed and reliability has recently been completed. Users in one part of the network are experiencing dramatically decreased throughput and loss of connectivity. Which of the LAN design goals was not met for these users?*** functionalitysustainabilityadaptabilitymanageabilityscalability13 To reduce cost on a new network design, administrators select switches that initially will have 100 Mbps interface modules installed but will also have the ability to support 1000 Mbps interface modules. Which of the LAN design goals are being utilized? (Choose two.)sustainabilityreliabilitymanageability*** adaptabilityfunctionality*** scalability14 What will increase the number of broadcast domains in a network? (Choose two.)replacing hubs with switches*** segmenting the network by installing a router*** creating VLANs for each workgroupadding additional hubs to the local area networkreplacing routers with LAN switchesadding bridges to connect different workgroups15 Where should DNS and email servers be located?IDF*** MDFHCCVCCPOP16 Which LAN standard uses CSMA/CD as its access method?FDDI*** EthernetWirelessToken Ring17 VLAN1 and VLAN2 have been configured on a switch. What must be done for hosts on VLAN1 to communicate with hosts on VLAN2?VLAN overlapping must be enabled on the switch.The MAC address must be added to the ARP table in the switch.*** A router must be configured to allow routing between the VLANs.An entry in the switching table must be configured for each VLAN.Communication between VLANs is automatically enabled on switches18 A network administrator needs to increase bandwidth and reduce traffic on a network. What should be used in the access layer of the hierarchical network design model to dedicate bandwidth to users while limiting broadcast domains?one router with multiple fast Ethernet interfacesmultiple routers with Fast Ethernet interfacesmulti-port gigabit switches*** switches running VLANsmanaged smart hubs19 Which devices are considered acceptable for creating more connection points at the end of horizontal cable runs? (Choose two.)*** hubsbridges*** switchesrouters20 Why is it important that the data carrying capacity of vertical cabling be greater than that of the horizontal cable?Vertical cabling is reserved for high bandwith video conferencing.Vertical cabling carries traffic from the IDF to the user.Vertical cabling carries traffic from the enterprise out to the Internet.*** Vertical cabling carries traffic from multiple areas of the network.Layer-three packets move faster through vertical cabling [ Pobierz całość w formacie PDF ]
