Chapter 6 CISCO project practice test

Chapter 6 Cisco project for my Cisco class. In this chapter I learned about routers and how to connect a lot of things to them. How to configure them, what's inside them, and even how much they are like PC's.

Do you really understand chapter 6/CISCO routing? Take this to find out. Struggling with this chapter specifically? Take this to find out. Just keep taking it until you get a 100.

What is de-encapsulation?
- When the packet arrives at the network layer of the destination host, the host checks the IP header of the packet.
- When the end devices receive the data
- When the network layer encapsulates the protocol data unit from the transport layer into a packet.
What are the network layer protocols?
- Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6)
- encapsulation and application
- session and transport
- application and presentation
Why is a header used in the transport layer?
- The header is used to retrieve data
- The header is used to deliver the packet to the destination host
- The header is used to encapsulate data
Define: Best Effort
- When you try your best on a test
- IP is inherently unreliable because packet delivery is not guaranteed
- when you put so much effort into something
Define: Connectionless
- no connection established with the destination before sending data packets
- no connection in general
- when the wifi doesn't work at HHS
- Simply a teenager's worst nightmare
Define: Media Independent
- independent social media
- operation is independent of the medium carrying the data
- provides only the functions that are necessary to deliver a packet from a source to a destination over an interconnected system of networks
- independent teenagers online
What one thing does the sender not know in connectionless communication?
- how to make cookies
- when the data is coming
- if the letter arrived
- happiness
What one thing does the receiver not know in connectionless communication?
- if the receiver is present
- when the data is coming
- how to make brownies
- the true meaning of life
What may happen to data packets when using the Best Effort process?
- Packets may arrive at the destination corrupted, out of sequence, or not at all.
- packets will arrive on time and in the best condition
- The network layer then determines how large packets can be.
A true fact about IP packets
- they believe in themselves
- they can travel over different medias
- they make up IP addresses
What is it called when a router splits up a packet when forwarding it from one medium to another medium?
- breaking it
- fragmenting the packet or fragmentation.
- dropping the data
What is version?
- Contains an 8-bit binary value that is used to limit the lifetime of a packet.
- Contains a 4-bit binary value set to 0100 that identifies this as an IP version 4 packet.
- Formerly called the Type of Service (ToS) field, the DS field is an 8-bit field used to determine the priority of each packet
What is time-to-live?
- Contains an 8-bit binary value that is used to limit the lifetime of a packet.
- Contains a 4-bit binary value set to 0100 that identifies this as an IP version 4 packet.
- This 8-bit binary value indicates the data payload type that the packet is carrying
what is the difference between a Source IPv4 Address and a Destination IPv4 Address
- a Source IPv4 Address can only use unicast
- a Destination IPv4 Address can use multi, broad, and unicast
- all of the above
Which thing identifies each priorities for each packet?
- Differentiated services
- version
- Destination IPv4 Address
- protocol
Which thing is always set to 0100 for IPv4?
- version
- Time-To-Live
- Destination IPv4 Address
Which thing identifies the upper layer protocol to be used next?
- Destination IPv4 Address
- protocol
- Time-To-Live
- Version
Which thing identifies the IP address for the recipient host?
- Time-To-Live
- Destination IP address
- Version
- Protocol
What are some limitation to IPv4?
- IP address depletion
- Internet routing table expansion
- Lack of end-to-end connectivity
- All of the above
what are some improvements that IPv6 provides?
- Increased address space, Improved packet handling, Eliminates the need for NAT
- More RAM and NVRAM
- flash and bandwidth
how much space does 32-bit IPv4 address provide?
- 4,294,967,296 unique addresses
- 340,282,366,920,938,463,463,374,607,431,768,211,456, or 340 undecillion addresses
How much space does IPv6 address provide?
- 4,294,967,296 unique addresses
- 340,282,366,920,938,463,463,374,607,431,768,211,456
what is the loopback interface?
- when fruit loops attack
- the loops loop back
- when a host can ping itself by sending a packet to a special IPv4 address of 127.0.0.1
What is a local host?
- a host on the same local network as the sending host.
- LAN
- WAN
- LWAN
- MAN
What is a remote host?
- quite simply, a host on a remote network
- a host in town
- a host in the country, ya'll
What does the default gateway do?
- It sorts people in religion
- it protects computers from viruses or hackers
- It routes traffic to other networks
What does the show ip route command do?
- display the router’s IPv4 routing table
- display the router’s IPv6 routing table
- display the router’s routing table
What does the "C" entry do?
- Identifies a directly-connected network
- C stuff
- It Sees you?
What does the "L" entry do?
- Identifies that this is a local interface
- Identifies that this is a remote interface
- Identifies that this is an interesting interface
What specific company does the Branch help out?
- that stick on a tree
- that stick on the ground
- Teleworkers, small businesses, and medium-size branch sites
- trees
What specific company does a WAN help out?

- Large businesses, organizations, and enterprises.
- LAN services
What specific company does Service Provider help out?
- Large service providers.
- Small service providers
- medium service providers
What things do routers need just like computers?
- RAM
- ROM
- NVRAM
- OS
- CPU
- flash
- all of the above
define RAM
- This is volatile memory used in Cisco routers to store applications, processes, and data needed to be executed by the CPU.
- This non-volatile memory is used to store crucial operational instructions and a limited IOS
- This is non-volatile memory is used as the permanent storage for the startup configuration file
define NVRAM
- This is non-volatile memory is used as the permanent storage for the startup configuration file
- This non-volatile memory is used to store crucial operational instructions and a limited IOS
- his is volatile memory used in Cisco routers to store applications, processes, and data needed to be executed by the CPU
define ROM
- This non-volatile memory is used to store crucial operational instructions and a limited IOS.
- This is non-volatile memory is used as the permanent storage for the startup configuration file
- This non-volatile computer memory used as permanent storage for the IOS and other system related files such as log files, voice configuration files, HTML files, backup configurations, and more
define flash
- This non-volatile computer memory used as permanent storage for the IOS and other system related files such as log files, voice configuration files, HTML files, backup configurations, and more
- This is non-volatile memory is used as the permanent storage for the startup configuration file
