# Assessment 1

#### Let's apply what you have learned so far to a specific scenario. Choose the most correct response (choose ALL that apply).

You are a network administrator tasked with implementing overlay services for a new application that requires flexible data storage and transaction management. During the implementation, a team member raises concerns about the security of the data stored in the overlay services. How do you address their concerns while ensuring the team understands the benefits of using overlay services?<br>

* [x] Explain that overlay services utilize the blockchain for cryptographic proofs and timestamped records, ensuring data integrity.
* [x] Assure them that the overlay services are designed to enhance security by allowing data to be stored off-chain while still being verifiable.
* [ ] Dismiss their concerns, stating that overlay services are widely used and therefore must be secure.
* [ ] Suggest that they should not worry about security since the application is still in the testing phase.

**Notes to Learners**

When addressing concerns about security in overlay services, it's important to highlight how these services leverage the underlying blockchain technology to provide cryptographic proofs and timestamped records. This ensures that while data is stored in a flexible and scalable manner, its integrity is maintained. Dismissing concerns or suggesting that security is not a priority can lead to vulnerabilities and a lack of trust in the system.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://hub.bsvblockchain.org/higher-learning/bsv-academy/bsv-network-topology/essentials-of-overlay-services/assessment-1.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
