Intro to networks 8.3, 8.4, 8.5

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

• IP address depletion
• increased network complexity and internet routing table expansion
• always on connections
• lack of end to end connectivity
• too many IPv4 addresses available

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

• header supports additional fields for complex packets
• increased the ip address space
• supports class based networks
• uses a simple header to provide improved packet handling

Which is true of the IPv6 packet header?

• the hop limit field replaces the ipv4 time to live field
• the source and destination ipv6 addresses change while traveling from source to destination
• the versions field identifies the next header

Which technology in IPv4 networks provides a way for multiple devices to share a single public IPv4 address?

• a) Network Address Translation (NAT)
• b) End-to-end connectivity
• c) IPv6 protocol

What is one of the challenges caused by the use of NAT in IPv4 networks?

• a) Lack of end-to-end connectivity
• b) Increased network complexity
• c) IPv4 address depletion

What is one of the improvements provided by IPv6 compared to IPv4?

• a) Increased address space
• b) Improved packet handling
• c) Need for NAT

What is one advantage of IPv6 that eliminates the need for NAT?

• a) Increased address space
• b) Improved packet handling
• c) Large number of public IPv6 addresses

What is one major design improvement of IPv6 over IPv4?

• a) Increased address space
• b) Simplified header
• c) Support for NAT

What happens to some of the IPv4 fields in the IPv6 packet header?

• a) They remain the same
• b) They change names and positions
• c) They are no longer required

What is the purpose of the traffic class field in IPv6?

• a) It identifies the source and destination IP addresses.
• b) It specifies the version of the IPv6 protocol.
• c) It indicates the priority or quality of service (QoS) for the packet.
• d) It defines the size of the IPv6 header.
