Short answer. No. Binding you as a guarantor or surety is one of the enumerated acts a general power of attorney cannot reach. Because it exposes your assets to someone else's debt without any corresponding benefit to you, the authority has to be given expressly.

Why this act is singled out
Most contracts an agent makes bring something back — property, money, services. Standing behind another person's debt brings nothing. You take on the entire downside of an obligation that was never yours, in exchange for no consideration at all, and you may not even know the debtor. That asymmetry is the reason the Code refuses to let this be inferred from a general authority to manage your affairs. It has to be a decision you actually made and recorded.
The clause covers both forms of the undertaking
The wording reaches an agent obligating you as a guarantor or surety. The two are not identical in how and when the creditor may proceed against you, but for the purpose of this article they are treated together — either way the agent needs a special power. So the answer does not change according to how the document your agent signed happens to be labelled. What matters is that you were put on the hook for another person's obligation.
A related item on the same list
The article separately requires a special power to bind the principal to render some service without compensation, and to waive any obligation gratuitously. Read together with this clause, a pattern emerges: wherever an agent would give something away for nothing, the Code demands express authority. If you are drafting or reviewing a power of attorney, these gratuitous-act clauses are the ones worth reading line by line, because they are the ones a broadly worded instrument is most likely to be argued into covering.
If it has already happened
Where an agent acted without authority or beyond it, Art. 1317 makes the resulting contract unenforceable unless the principal ratifies it, expressly or impliedly, before the other contracting party revokes. That is a real protection, but it is not automatic and it can be lost by conduct that looks like acceptance. This is general information about how the Code allocates these risks; whether a particular undertaking binds you turns on the terms of the power and on what was done afterwards.
