CCNA V7 - Chapter 8 - Network Layer

Data Link Layer

Which layer is responsible for taking an IP packet and preparing it for transmission over the communications medium?

Transport Layer

Which OSI layer sends segments to be encapsulated in an IPv4 or IPv6 packet?

Fragmentation

What is the term for splitting up an IP packet when forwarding it from one medium to another medium with a smaller MTU?

Best Effort

Which delivery method does not guarantee that the packet will be delivered fully without errors?

-destination IP address
-source IP address

Which are the two most commonly referenced fields in an IPv4 packet header that indicate where the packet is coming from and where it is going? (Choose two.)

The source and destination IPv4 addresses remain the same while travelling from source to destination.

Which statement is correct about IPv4 packet header fields?

Header Checksum

Which field is used to detect corruption in the IPv4 header?

Protocol

Which field includes common values such as ICMP (1), TCP (6), and UDP (17)?

-IP address
-increased network complexity and internet routing table expansion
-lack of end-to-end connectivity

Which three options are major issues associated with IPv4? (Choose three.)

-increased the IP address space
-uses a simpler header to provide improved packet handling

Which two options are improvements provided by IPv6 as compared to IPv4? (Choose two.)

-it consist of 40 octets
-in contains 8 header fields

Which is true of the IPv6 header?

The hop limit field replaces the IPv4 time to live field.

Which is true of the IPv6 packet header?

Local hosts can reach each other without the need of a router.

Which statement about host forwarding decisions is true?

The default gateway address is the IP address of the router on the local network.

Which default gateway statement is true?

-netstat -r
-route print

Which two commands could be entered on a Windows host to view its IPv4 and IPv6 routing table? (Choose two.)

show ip route

What is the command used on a Cisco IOS router to view the routing table?

a learned route dynamically from OSPF

What does a code of "O" indicate next to a route in the routing table?

default route

This type of route is also known as a gateway of last resort.

They are manually configured

Which is a characteristic of static routes?

True

True or False? A router can be configured with a combination of both static routes and a dynamic routing protocol.
