CCNA V7.0 CH 1–7 MIDTERM ACTUAL EXAM
QUESTIONS AND VERIFIED SOLUTIONS 2026
◉ What type of communication rule would best describe CSMA/CD?
Answer: access method
◉ Which three basic parts are common to all frame types supported
by the data link layer? Answer: *Header
*Data
*Trailer
◉ What three items are contained in an Ethernet header and trailer?
Answer: *Source MAC address
*Destination MAC address
*Error-checking information
◉ What are three ways that media access control is used in
networking? Answer: *Ethernet utilizes CSMA/CD.
*Media access control provides placement of data frames onto the
media.
*Data link layer protocols define the rules for access to different
media.
, ◉ What is the function of the CRC value that is found in the FCS field
of a frame? Answer: To verify the integrity of the received frame.
◉ A network team is comparing physical WAN topologies for
connecting remote sites to a headquarters building. Which topology
provides high availability and connects some, but not all, remote
sites? Answer: partial mesh
◉ Which media communication type does not require media
arbitration in the data link layer? Answer: full-duplex
◉ A network administrator is connecting two modern switches
using a straight-through cable. The switches are new and have never
been configured. Which three statements are correct about the final
result of the connection? Answer: *The link between the switches
will work at the fastest speed that is supported by both switches.
*The link between switches will work as full-duplex.
*The auto-MDIX feature will configure the interfaces eliminating the
need for a crossover cable.
◉ Which advantage does the store-and-forward switching method
have compared with the cut-through switching method? Answer:
frame error checking
