Networking Quiz

Which term describes the state of a network when the demand on the network resources exceeds the available capacity?

• convergence

• congestion

• optimization

• synchronization

What is a characteristic of a converged network?

• It provides only one path between the source and destination of a message.

• It limits the impact of a failure by minimizing the number of devices affected.

• It delivers data, voice, and video over the same network infrastructure.

• A converged network requires a separate network infrastructure for each type of communication technology.

What is the Internet?

• It is a network based on Ethernet technology.

• It provides network access for mobile devices.

• It provides connections through interconnected global networks.

• It is a private network for an organization with LAN and WAN connections.

What two criteria are used to help select network media?

• The distance the media can successfully carry a signal.

• The environment where the media is to be installed.

• The cost of the end devices utilized in the network.

• The number of intermediary devices installed in the network.

• The types of data that need to be prioritized.

Why is it important to configure a hostname on a device?

• A Cisco router or switch only begins to operate when its hostname is set.

• A hostname must be configured before any other parameters.

• To identify the device during remote access (SSH or telnet).

• To allow local access to the device through the console port.

Why would a Layer 2 switch need an IP address?

• To enable the switch to send broadcast frames to attached PCs.

• To enable the switch to function as a default gateway.

• To enable the switch to be managed remotely.

• To enable the switch to receive frames from attached PCs.

Which two features are characteristics of flash memory?

• Flash receives a copy of the IOS from RAM when a device is powered on.

• Flash provides nonvolatile storage.

• The contents of flash may be overwritten.

• Flash is a component in Cisco switches but not in Cisco routers.

• The contents of flash may be lost during a power cycle.

Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?

• 802.1

• 802.11

• 802.3

• 802.2

If the default gateway is configured incorrectly on the host, what is the impact on communications?

• The host is unable to communicate on the local network.

• The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.

• The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network.

• There is no impact on communications.

Which characteristic describes crosstalk?

• The distortion of the network signal from fluorescent lighting.

• The distortion of the transmitted messages from signals carried in adjacent wires.

• The weakening of the network signal over long cable lengths.

• The loss of wireless signal over excessive distance from the access point.
