Characteristics of the IP Protocol

100

No connection with the destination is established before sending data packets.

What is Connectionless?

200

Packet delivery is not guaranteed.

What is Best effort?

300

Operation is independent of the medium carrying the data.

What is Media Independent?

400

This characteristic is the maximum size of the PDU that each medium can transport.

What is maximum transmission unit (MTU)?

500

In some cases an intermediate device must split up a packet when forwarding it from one medium to a medium with a smaller MTU.

What is Fragmentation?

Configuration of a Default Gateway

100

For a default gateway on a host, each router interface is configured with a separate _____ in a separate network

What is IP address?

200

To configure a default gateway on a switch use the following ______ global configuration command.

What is ip default-gateway?

300

Configuring the IP address on a switch is done on the _____

What is switch virtual interface (SVI)?

400

While it does not matter what address is actually configured on the router interface, the IP address of the host device and the router interface address, must be in the same _______

What is network?

500

A common misconception is that the _____ uses its configured default gateway address to determine where to forward packets originating from hosts connected to the _____ and destined for hosts on a remote network.

What is Switch?

Anatomy of a sssw

100

A router has special memory that includes flash and _____

What is Nonvolatile random-access memory (NVRAM)?

200

This component is an option that offloads from the CPU processor-intensive functions such as encryption.

What is Advanced Integration Module?

300

Holds running configuration, running IOS, routing tables, and buffers.

What is RAM?

400

These are the console and auxiliary ports used to configure, manage, and troubleshoot the router. Unlike LAN and WAN interfaces, management ports are not used for packet forwarding.

What is Management ports?

500

This cache contains the IPv4 address-to-MAC address mappings, similar to the ____ on a PC. Used on routers that have LAN interfaces, such as Ethernet interfaces.

What is ARP cache?

Router Bootup

100

The IOS file itself is several megabytes in size and, similar to Cisco IOS switches, is stored in _____

What is flash memory?

200

Contains commands that are used to initially configure a router and create the running configuration file stored in RAM.

What is Startup configuration file (startup-config)?

300

During this phase, the POST process is used to test the router hardware. During this self-test, the router executes diagnostics from ROM on several hardware components. After POST is has been completed, the router executes the bootstrap program.

What is Phase 1?

400

During this phase the bootstrap program then searches for the startup configuration file (startup-config) in NVRAM. the running config file contains interface addresses, starts routing processes, configures router passwords, and defines other characteristics of the router.

What is Phase 3?

500

The IOS is typically stored in flash memory and is copied into RAM for execution by the CPU. During self-decompression of the IOS image file, a string of hash by the CPU. During self-decompression of the IOS image file, a string of hash (pound) signs (#) will be displayed.

What is Phase 2?

Miscellaneous

100

This part of the router has the current configuration loaded and located.

What is RAM?

200

This layer is concerned with the end-to-end communication over the network?

What is Network?

300

This is the route you see when you use the netstat -r command on a host. It represents that destinations without a specified route are forwarded to the gateway.

What is 0.0.0.0 0.0.0.0?

400

After configuring a host, communication will be limited to hosts in the local network because the ____ was not configured.

What is gateway?

500

This field in an Ethernet frame is used for error detection.

What is Frame Check Sequence?
