• adding bridges to connect different workgroups
3 At which layer of the hierarchical design model do users connect to the network?
• application
• access
• distribution
• network
• core
4 Where should DNS and email servers be located?
• IDF
• MDF
• HCC
• VCC
• POP
5 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 switches.
6 What type of cabling is specified by TIA/EIA standards for interconnection of Intermediate and Main Distribution Facilities?
• patch cables of variable lengths
• horizontal cross-connect cabling
• vertical cross-connect cabling
• parallel cross-connect cabling
7 Which of the following affect network availability? (Choose three.)
• throughput
• response time
• workstation speed
• access to resources
• desktop applications
8 Which of the following are requirements of LAN design? (Choose three.)
• adaptability
• manageability
• operability
• scalability
• stability
9 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.
10 A distribution layer switch operates at which OSI layers? (Choose two.)
• access
• data link
• network
• internet
• transport
11 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.)
• sustainability
• reliability
• manageability
• adaptability
• functionality
• scalability
12 Which of the following are characteristics of the core layer of the hierarchical network design model? (Choose three.)
• redundant paths
• high-level policy enforcement
• packet manipulation
• media transitions
• rapid forwarding of traffic
• no packet filtering
13 Which of the following are features of the access layer of the hierarchical network design model? (Choose two.)
• inter-VLAN routing
• Layer 2 filtering
• Layer 3 filtering
• microsegmentation
• bandwidth security
14 Which LAN standard uses CSMA/CD as its access method?
• FDDI
• Ethernet
• Wireless
• Token Ring
15 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 interfaces
• multiple routers with Fast Ethernet interfaces
• multi-port gigabit switches
• switches running VLANs
• managed smart hubs
16 Which devices are considered acceptable for creating more connection points at the end of horizontal cable runs? (Choose two.)
• hubs
• bridges
• switches
• routers
17 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?
• functionality
• sustainability
• adaptability
• manageability
• scalability
18 When designing a LAN, at which layer of the OSI model does the process of segmenting collision domains occur?
• Layer 1
• Layer 2
• Layer 4
• Layer 7
19 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 layer
• preventing unnecessary security policy decisions from burdening the access layer
• maintaining a consistent three-layer security policy
• isolating the access layer from traffic destined for other networks
20 Which hierarchical design model layer is responsible for containing network problems to the workgroups in which they occur?
• application
• access
• distribution
• network
• core
