NEW QUESTION # 36
Which layer of the OSI model provides error detection and defines how access to the media is controlled?
- A. Network layer
- B. Data link layer
- C. Presentation layer
- D. Physical layer
Answer: B
Explanation:
The Data Link Layer (Layer 2) of the OSI model is responsible for node-to-node data transfer and plays a crucial role in error detection and media access control. It ensures that data frames are transmitted to the correct device on a local network segment.
This layer is divided into two sublayers:
* Logical Link Control (LLC):Manages frame synchronization, flow control, and error checking.
* Media Access Control (MAC):Controls how devices on the network gain access to the medium and permission to transmit data.
Together, these sublayers ensure reliable data transmission by detecting and possibly correcting errors that may occur in the Physical Layer. They also manage how devices share the transmission medium, preventing collisions and ensuring orderly communication.

NEW QUESTION # 37
What is the primary role of a switch in a local area network?
- A. to encrypt data transmissions for security
- B. to route data packetsbetween different networks
- C. to divide the network into separate collision domains
- D. to provide wireless connectivity to LAN devices
Answer: C
Explanation:
In a local area network (LAN), the primary function of aswitch is to operate at Layer 2 (Data Link Layer) of the OSI model. Switches use MAC addresses to forward frames to the appropriate destination ports. This targeted forwarding mechanism divides the network into separate collision domains for each switch port. By isolating collision domains, switches significantly reduce the chance of collisions, enhancing the performance and efficiency of the network.
Unlike hubs, which forward all traffic to all ports (thus creating a single collision domain), switches intelligently forward only the necessary traffic to the correct port. This capability allows multiple simultaneous conversations on different switch ports without interference.
Routers, which operate at Layer 3 (Network Layer), are used to route packets between different networks, not within the same LAN. Wireless connectivity is provided by wireless access points (WAPs), not switches.
Encryption is typically handled by security protocols or devices such as firewalls and not by switches directly.

- A. Disconnect the SFP latch.
- B. Install the replacement SFP module.
- C. Reinstall dust plugs in the optical bores.
- D. Observe the port status LED.
Answer: C
Explanation:
After disconnecting the network cable from an SFP transceiver, theimmediate next step is to reinstall the dust plugsinto the optical bores. This action prevents contamination from dust or debris that can damage the optical interfaces or degrade performance.
It's important to protect the exposed optical port before handling the rest of the transceiver module. Dust plugs help maintain the integrity of the component until a new cable or module is connected.
