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.

Is It Safe to Use LinkedIn Automation?
Stolb23 [73]

Answer:

A lot of people have claimed that they lost their full-established accounts after using LinkedIn automation tools. LinkedIn detected the activity and blocked their accounts.  

But it’s not the tool that causes spam, it’s the approach you adopt while using these tools.  

Many people think that LinkedIn automation tools(LinkedCamp) can generate leads magically over the night. They send thousands of connection requests and messages using automation and as a result, LinkedIn detects their activity.  This is not how it works. You need a proper strategy to leverage the potential of these tools. Even the best LinkedIn automation tools cannot guarantee success if you try to overdo the activities.
