What are two characteristics of RAM on a Cisco device? (Choose two.)
- RAM provides nonvolatile storage.
- The configuration that is actively running on the device is stored in RAM.
- The contents of RAM are lost during a power cycle.
- RAM is a component in Cisco switches but not in Cisco routers.
- RAM is able to store multiple versions of IOS and configuration files.
Correct

Incorrect

RAM stores data that is used by the device to support network operations. The running configuration is stored in RAM. This type of memory is considered volatile memory because data is lost during a power cycle. Flash memory stores the IOS and delivers a copy of the IOS into RAM when a device is powered on. Flash memory is nonvolatile since it retains stored contents during a loss of power.

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
Correct

Incorrect

A switch, as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address. The IP address must be applied to a virtual interface rather than to a physical interface. Routers, not switches, function as default gateways.

A technician is adding a new PC to a LAN. After unpacking the components and making all the connections, the technician starts the PC. After the OS loads, the technician opens a browser, and verifies that the PC can reach the Internet. Why was the PC able to connect to the network with no additional configuration?
- The PC does not require any additional information to function on the network.
- The PC came preconfigured with IP addressing information from the factory.
- The PC was preconfigured to use DHCP.
- The PC used DNS to automatically receive IP addressing information from a server.
- The PC virtual interface is compatible with any network.
Correct

Incorrect

The new PC was preconfigured to use DHCP. When the PC is connected to a network that uses DHCP, it gets the IP address settings from the DHCP server that will allow it to function on the network. All devices require at least an IP address and subnet mask to function on a LAN. DNS does not automatically configure addresses on hosts. PC virtual interfaces are not universally compatible with LANs and do not necessarily provide a host with an IP address. At this place in the course, virtual interfaces are used on network switches.
