Computer Network MCQ – Questions and Answers – Part 7

Networking MCQs questions with answers to prepare for exams, tests, and certifications. These questions are taken from a real written exam and some parts are taken from an interview. So you will find questions on CCNA, TCP/IP, Protocols, IP addressing issues, OSI model, and more. This MCQ will easily prepare anyone to pass their exam.

1. Which layer is responsible for handling the package delivery?

A Network layer

B Transport layer

C Session layer

D Data link layer

The transport layer is responsible for end-to-end communication. It provides logical communication between application processes running on different hosts.

2. What address identifies a process on a host?

A Physical address (MAC)

B Logical address (IP)

C Port address

D Specific address

Port address is a way to identify a specific process to which a network message should be transmitted.

3. Which layer provides services to the user?

A Application Layer

B Session Layer

C Presentation layer

D None of the above

The application layer consists of protocols(HTTP, FTP, etc..) that focus on communication between processes on an IP network and provides a communication interface and services to end users.

4. The transmission rate is determined by the______?

A Network Layer

B Physical Layer

C Data Link Layer

D Transport layer

The physical layer handles binary transmission (0 and 1) between different devices and supports electrical or mechanical interfaces connecting to the physical medium for synchronized communication.

5. The physical layer is about ______?

A Bit-by-bit delivery

B Process for handling delivery

C Delivery between applications

D None of the above

6. Which transmission medium has the highest transmission speed in a network?

A Coaxial cable

B Twisted pair cable

C Optical fiber

D Electrical cable

Fiber optics is considered to have the highest transmission speed of all those mentioned above. Fiber optic transmission operates at 1000Mb/s. It is called 1000Base-Lx while the IEEE standard is 802.3z.

7. Bits can be sent on directed and un-directed media as an analog signal, is a _________?

A Digital modulation

B Amplitude modulation

C Frequency modulation

D Phase modulation

Digital modulation is the process of coding a digital signal in amplitude, phase or frequency of the transmitted signal.

8. The part of the physical layer that interfaces with the media access control sublayer is called_________?

A physical signaling sublayer

B LLC sublayer

C MAC sublayer

D None of the above

In Layer 2, the Media Access Control (MAC) sublayer provides addressing and channel access control mechanisms that allow multiple terminals or network nodes to communicate in a network.

9. The physical layer provides_________?

A mechanical specifications of electrical connectors and cables

B electrical specification on the signal level of the transmission line

C specification for IR on optical fiber

D All the answers are true

10. In asynchronous serial communications, the physical layer provides_________?

A signaling framed by the START and STOP bits

B flow control

C Both A and B are true.

D None of the above
