Module 8 Intro Into Networking

Which is true of the IPv6 header?

*it consists of 40 octets. *it contains 8 header fields.

Which statement about host forwarding decisions is true?

Local hosts can reach each other without a router

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

Protocol

Which is true of the IPv6 packet header?

The Hop limit field replaces the IPv4 Time to Live field

Which default gateway statement is true?

The default gateway address is the IP address of the router or local network

Which statement is correct about IPv4 packet header fields?

The source and destination IPv4 addresses will remain the same while traveling from source to destination

Which is a characteristic of static routes?

They are manually configured

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

Transport Layer

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

True

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

a route learned dynamically from OSPF

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

default route

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

netsat -r, route print

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

show ip route

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

Best Effort

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

Data Link Layer

What 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.)

Destination & Source IP address

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

Fragmentation

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

Header Checksum

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

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

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

Increased the IP address space, uses a simpler header to provide improved packet handeling
