CCNAv3 Chapter 1 Quiz Answers (100%)

Greetings, welcome to Seeseenayy.
Below is the Chapter 1 Quiz for CCNA 3, hand-crafted by yours truly. 

We have included the tutorial/explanations from the quiz page to help describe each response. Most answer pages don't ever have a tutorial section-- this is the least we could do.

CHAPTER 1 - QUIZ

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 Explanation:
Refer to curriculum topic: 1.2.2
Network edge routers provide customer interactivity, personalization, and mobility. Wherever customers can access an Internet connection, they can access their content. Branch routers provide simple network configuration and management while maintaining highly available networks. Modular routers are used to provide greater flexibility in which interfaces are used during network design and installation. Service provider routers provide end-to-end scalable solutions. Customers do not remotely access or connect directly to a service provider router.


How much traffic is a 48-port gigabit switch capable of switching 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 Explanation: 
Refer to curriculum topic: 1.2.1
A switch operating at full wire speed is capable of switching the cumulative amount of each port on the switch. A 48-port gigabit switch could forward (48 x 1 Gb/s = 48 Gb/s) of data. Forwarding rates are determined based on the capabilities of each switch.

Match the design model layer to the appropriate network function. (Not all options are used.)
core layer - Provides a high-speed backbone link between disperesed networks.
distribution layer - Forwards traffic from one local network to another.
access layer - Provides connectivity for the users.
Refer to curriculum topic: 1.1.1


Fill in the blank. 
The number of ports available on a single switch is referred to as  "Port Density"

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***

Refer to curriculum topic: 1.1.1
All modern enterprise networks are expected to support critical applications, converged network traffic, diverse business needs, and provide centralized administrative control. Users expect enterprise networks to be up 99.999 percent of the time (not 90 percent.). Support for limited growth is not a usual network design criterion.

Fill in the blank.
Among the beneficial functions of a router are enhanced network security and containment of "Broadcast Traffic"***.


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***
  removing switches which cause loops 

Refer to curriculum topic: 1.1.2
Using duplicate equipment and using redundant paths are two methods to help prevent network disruptions. The use of VLANs would not affect network availability. Changing the routing protocol could actually reduce availability during convergence. Loops, which are created by the provision of redundant paths, are managed by protocols without removing devices.

Which network design solution will best extend access layer connectivity to host devices?
  implementing EtherChannel*** 
  implementing wireless connectivity 
  implementing redundancy 
  implementing routing protocols 
Refer to curriculum topic: 1.1.2
EtherChannel allows more data to be moved at the access layer, but does not provide network expansion. Redundancy is used to provide failover solutions but does not focus on network expansion. Routing protocols are not used to provide network expansion at the access layer. Wireless connectivity provides network access to a large number of users at the access layer.   


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.
Refer to curriculum topic: 1.2.3
Out-of-band device management is used for initial configuration or when a network connection is unavailable. Configuration that uses out-of-band management requires a direct connection to a console or AUX port and a terminal emulation client.

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*** 
Refer to curriculum topic: 1.1.2
VLANs create several groups of users which use a single physical link. Trunk ports are single physical links. Subinterfaces allow one physical link to be used to create several logical links. EtherChannel provides the ability to combine multiple physical links into a single logical link.
