CCNA 1 - MODULE 8 EXAM QUESTIONS AND
ANSWERS
/. Which layer is responsible for taking an IP packet and preparing it for transmission
over the communications medium? - Answer-data link layer
/.Which OSI layer sends segments to be encapsulated in an IPv4 or IPv6 packet? -
Answer-transport layer
/.What is the term for splitting up an IP packet when forwarding it from one medium to
another medium with a smaller MTU? - Answer-fragmentation
/.Which delivery method does not guarantee that the packet will be delivered fully
without errors? - Answer-best effort
/.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.) -
Answer-destination IP address / source IP address
/.Which statement is correct about IPv4 packet header fields? - Answer-the source and
destination IPv4 addresses remain the same while travelling from source to destination
/.Which field is used to detect corruption in the IPv4 header? - Answer-Header
Checksum
/.Which field includes common values such as ICMP (1), TCP (6), and UDP (17)? -
Answer-protocol
/.Which three options are major issues associated with IPv4? (Choose three.) - Answer-
IP address depletion/ increased network complexity and internet routing table
expansion/ lack of end-to-end connectivity
/.Which two options are improvements provided by IPv6 as compared to IPv4? (Choose
two.) - Answer-increased the IP address space/ uses a simpler header to provide
improved packet handling
/.Which is true of the IPv6 header? - Answer-it consists of 40 octets / it contains 8
header fields
/.Which is true of the IPv6 packet header? - Answer-the Hop Limit field replaces the
IPv4 Time to Live field
