1. A network engineer is explaining the OSI model to a junior colleague. The colleague asks which OSI layer is responsible for end-to-end error recovery and flow control between hosts. Which layer should the engineer identify?

A Layer 2 (Data Link)

B Layer 3 (Network)

C Layer 4 (Transport)

D Layer 5 (Session)

2. A network technician is analyzing a captured Ethernet II frame and identifies the following fields: Preamble, Destination MAC, Source MAC, Type, Data, and FCS. The technician asks which field is used to identify the Layer 3 protocol encapsulated inside the frame. Which field should be identified?

A Preamble

B EtherType (Type) field

C Source MAC address

D FCS (Frame Check Sequence)

3. A network engineer must subnet the 192.168.10.0/24 network to support at least 50 hosts per subnet while wasting as few addresses as possible. Which subnet mask should the engineer use?

A /24 (255.255.255.0)

B /27 (255.255.255.224)

C /26 (255.255.255.192)

D /25 (255.255.255.128)

4. A Cisco switch port is connected to a shared hub. The hub has five workstations attached to it. A network engineer must determine the number of collision domains and broadcast domains created by this topology. Which answer is correct?

A 5 collision domains, 1 broadcast domain

B 1 collision domain, 1 broadcast domain

C 5 collision domains, 5 broadcast domains

D 1 collision domain, 5 broadcast domains

5. A network engineer configuring a legacy 10BASE-T Ethernet segment notes that the connected devices experience frequent collisions. The engineer explains to the team how CSMA/CD handles this situation. Which of the following BEST describes the CSMA/CD collision recovery process?

A A jamming signal is sent, both stations wait a random backoff time, then retry transmission

B A token is passed to the next station to prevent further collisions

C Both stations stop and wait a fixed 9.6-microsecond time before retrying

D The frame is forwarded to a central collision controller for retransmission
