Question

You are informed that all the users within the network are unable to access the Internet. You decide to start troubleshooting from the Physical layer of the OSI model. Which of the following approaches would you use to troubleshoot this problem?a. Random layer approachb. Divide and conquer approachc. Bottom up approachd. Top down approach

Answer 1

Answer:

C. Bottom-up approach will be used in this scenario.

Explanation:

The OSI or Open Systems Interconnection is an architecture that comprises of seven (7) layers, each layer unique in its functionality. The layer is listed below:

7. Application layer

6. Presentation layer

5. Session layer

4. Transport layer

3. Network layer

2. Data link layer

1. Physical layer

Layer 1 - 3 are considered the hardware layers, Layer 4 is considered as the heart of the OSI model while layers 5 - 7 are considered the software layers.

Back to our question, once you decide to troubleshoot from the physical layer of the OSI model, you are troubleshooting this problem from a bottom-up approach.
