# 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 responsible for maintaining the blockchain nodes in your organization. You notice that one of the nodes is running low on disk space due to the accumulation of old transactions. What steps do you take to manage the disk space effectively?

* [x] Identify and discard spent transactions that are no longer necessary for the ongoing operation of the network.
* [x] Ensure that the network has built enough blocks on top of the old transactions to make them immutable before removing references.
* [ ] Increase the disk space of the node without addressing the underlying issue of old transactions.
* [ ] Ignore the low disk space warning and continue processing new transactions.

**Notes to Learners**

To effectively manage disk space in a blockchain network, it is essential to identify and discard spent transactions that are no longer necessary. This helps in reclaiming disk space and maintaining the performance of the node. Additionally, ensuring that transactions are buried under a sufficient number of blocks makes them immutable, allowing for their safe removal from local copies of the blockchain. Simply increasing disk space or ignoring the issue does not address the root cause and can lead to further inefficiencies.

# 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/bitcoin-whitepaper-series/section-7-reclaiming-disk-space-bitcoin-whitepaper/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.
