What happens to data as it moves from the upper to the lower layers of the OSI model on a host system?
The header and trailer are stripped off through decapsulation.
The data is sent in groups of segments that require two acknowledgments.
The data moves from the physical layer to application layer.
It is encapsulated with a header at the beginning and a trailer at the end.

Objective 1.1/Day 2 -
Match the OSI model layers with their corresponding characteristics or functions:
Provides end-user services and interfaces for applications.
Application Layer
Responsible for data encryption, compression, and translation.
Presentation Layer
Manages communication sessions, including establishment and termination.
Session Layer
Objective 1.1/Day 2 -
Match the OSI model layers with their corresponding characteristics or functions:
Segments, reassembles, and ensures reliable end-to-end delivery of data.
Transport Layer
Routes data between different networks based on logical addresses.
Network Layer
Adds MAC addresses to data frames and manages access to the physical medium.
Data Link Layer
Converts data into bits and transmits/receives them over the physical medium.
Physical Layer
Objective 1.1/Day 2 -
You are troubleshooting a network issue where a device is unable to communicate with another device on a different network. You need to examine the network layer to identify routing problems. Which layer of the OSI model should you focus on to investigate routing issues, and what type of header information would you examine?
Layer 2 – Data link; Ethernet header
Layer 3 – Network; Internet Protocol (IP) header
Transport; Transmission Control Protocol (TCP) header
Layer 7 – Application; Payload
Objective 1.1/Day 2 -
A network engineer is analyzing a data packet to determine the type of application protocol being used in a communication between two devices. Which layer of the OSI model should the engineer focus on, and what specific part of the packet would be most relevant?
Layer 1 – Physical; Payload
Layer 4 – Transport; TCP flags
Layer 5 – Session; Session information
Layer 7 – Application; Payload
Objective 1.1/Day 2 -
You need to configure a network to ensure that the maximum amount of data that can be sent in a single packet is optimized to prevent fragmentation. Which concept should you focus on, and which layer of the OSI model does it pertain to?
Maximum transmission unit (MTU); Layer 1 – Physical
Payload; Layer 7 – Application
Maximum transmission unit (MTU); Layer 3 – Network
TCP flags; Layer 4 – Transport
