**Question 3**

1. We are asked:  
   "Which type of attack overloads a network with excessive requests, preventing normal operations?"

2. A network is overloaded when it receives too many requests, which prevents it from responding to legitimate traffic. This type of attack is known as a **denial-of-service (DoS) attack** or, when distributed across multiple sources, as a **distributed denial-of-service (DDoS) attack**.

3. Among the given options:  
   - **(a)** Man-in-the-middle attack: Involves intercepting communications between two parties.  
   - **(b)** SQL injection: Involves inserting malicious SQL queries into an application to manipulate a database.  
   - **(d)** Ransomware: Involves encrypting a victim’s data and demanding a ransom.

4. None of these options exactly match the description of overloading a network with excessive requests. The correct answer should be a denial-of-service attack, which is missing from the provided choices.

5. Thus, the correct answer is the denial-of-service (DoS) attack, which corresponds to choice **(c)** (assuming it was meant to be listed, but it is absent).

**Question 4**

1. We are asked:  
   "What are the three elements of the CIA triad in cybersecurity?"

2. The CIA triad stands for the fundamental security principles:  
   - **Confidentiality**: Ensuring that information is not disclosed to unauthorized individuals.  
   - **Integrity**: Assuring the accuracy and completeness of data.  
   - **Availability**: Guaranteeing that information and resources are accessible to authorized users when needed.

3. Comparing the choices:  
   - **(a)** Confidentiality, Integrity, Availability  
   - **(b)** Control, Implementation, Authentication  
   - **(c)** Cryptography, Identification, Authorization  
   - **(d)** Compliance, Investigation, Action

4. The correct answer is clearly **(a) Confidentiality, Integrity, Availability**.

**Final Answers:**

3. The correct answer is a denial-of-service (DoS) attack (which would typically be listed as option **(c)**, though it is not shown here).  
4. The correct answer is **(a) Confidentiality, Integrity, Availability**.
**Question 3** Which type of attack overloads a network with excessive requests, preventing normal operations? - **(a)** Man-in-the-middle attack - **(b)** SQL injection - **(d)** Ransomware **Answer:** The correct answer is **(c)** Denial-of-service (DoS) attack. **Question 4** What are the three elements of the CIA triad in cybersecurity? - **(a)** Confidentiality, Integrity, Availability - **(b)** Control, Implementation, Authentication - **(c)** Cryptography, Identification, Authorization - **(d)** Compliance, Investigation, Action **Answer:** **(a) Confidentiality, Integrity, Availability**
