Which device forwards frames based on MAC addresses and sends data only to the intended port?
Switch filtering using MAC address tables
Hub broadcasting to every connected device
Modem converting analog to digital signals
Router forwarding based on IP subnets
What is the primary role of a modem in a home network?
Switching frames within a LAN segment
Routing packets between internal VLANs
Converting digital data to analog signals
Assigning IP addresses to local devices
Which statement best contrasts TCP and UDP for application use?

UDP reliable with ordered delivery
TCP connection‑oriented with guaranteed delivery
UDP stateful with flow control features
Arrange the TCP three‑way handshake steps from initiator to responder.
ACK, ACK‑SYN, SYN

A gaming app prefers minimal latency over guaranteed delivery. Which transport protocol is most appropriate?
UDP with mandatory sequence control
TCP with TLS session setup
UDP with simple datagram service
TCP with ordered byte stream
Which OSI layer is responsible for assigning source and destination IP addresses to enable routing across multiple networks?
Presentation layer handles data encryption formats
Network layer assigns IP addressing for routing
Application layer assigns friendly service identifiers
Data Link layer manages logical addressing across WANs
In the email scenario, what is the primary role of the Transport layer (Layer 4)?
Establish the initial user-to-server session handshake
Divide data into packets and ensure reliable delivery
Convert data frames into electrical or optical signals
Translate and encrypt data into standardized formats
A switch forwards frames within a LAN using which type of address at the Data Link layer?
Port numbers for processes
MAC hardware addresses
URL or domain names
IPv4 or IPv6 logical addresses
You must troubleshoot why an email arrives garbled though connectivity is stable. Which OSI layer is the most appropriate first focus?
Physical layer handling signaling and cabling
Network layer handling IP routing decisions
Presentation layer handling formatting and encryption
Session layer handling dialog establishment
Which Protocol Data Unit name applies at the transport layer during encapsulation of an HTTP request?
Datagram at transport layer
Segment at transport layer
Frame at transport layer
Packet at transport layer
When the network layer encapsulates data, which header field enables routing between subnets?
Frame Check Sequence field
EtherType value field
Destination IP address field
Source MAC address field
Which ordered sequence correctly names the Protocol Data Units as data moves down the TCP/IP stack for transmission?
Segment → Packet → Frame
Packet → Segment → Frame
Frame → Packet → Segment
Segment → Frame → Packet
A client sends an HTTP GET. Which specific transport-layer header fields are added before the IP header?
Source IP, destination IP, TTL, protocol
