Cisco 3 – Chaper 1: Quiz

question

Which two methods help to prevent the disruption of network services? (Choose two.) *using VLANs to segment network traffic *changing the routing protocols at regular intervals *installing duplicate equipment to provide failover services *using redundant connections to provide alternate physical paths
answer

installing duplicate equipment to provide failover services using redundant connections to provide alternate physical paths
question

Which network design solution will best extend access layer connectivity to host devices? *implementing EtherChannel *implementing wireless connectivity *implementing redundancy *implementing routing protocols
answer

implementing wireless connectivity
question

Among the beneficial functions of a router are enhanced network security and containment of ?________ traffic.
answer

broadcast
question

Which feature could be used in a network design to increase the bandwidth by combining multiple physical links into a single logical link? *VLANs *trunk ports *subinterfaces *EtherChannel
answer

EtherChannel
question

What is a characteristic of out-of-band device management? *Out-of-band device management requires a direct connection to a network interface. *It requires a terminal emulation client. *It requires Telnet, SSH, or HTTP to access a Cisco device. *It requires at least one network interface on the device to be connected and operational.
answer

It requires a terminal emulation client.
question

What are two expected features of modern enterprise networks? (Choose two.) *support for limited growth *support for critical applications *support for distributed administrative control *support for 90 percent reliability *support for converged network traffic
answer

support for critical applications support for converged network traffic
question

Fill in the blank. The number of ports available on a single switch is referred to as _________.
answer

density
question

Match the design model layer to the appropriate network function. (Not all options are used.) core layer distribution layer access layer
answer

core layer – provides a high-speed backbone link between dispersed networks distribution layer – forwards traffic from one local network to another access layer – provides connectivity to the users
question

Which type of router would an enterprise use to allow customers to access content anytime and anyplace, regardless of whether they are at home or work? *network edge routers *branch routers *modular routers *service provider routers
answer

network edge routers
question

How much traffic is a 48-port gigabit switch capable of generating when operating at full wire speed? *44 Gb/s, due to overhead requirements *24 Gb/s, because this is the maximum forwarding rate on Cisco switches *48 Gb/s, by providing full bandwidth to each port *1 Gb/s, because data can only be forwarded from one port at a time
answer

48 Gb/s, by providing full bandwidth to each port
