Preview Questions Cybersecurity Specialist (Defense) | Role Specific Skill

Question 1: What is "IPsec" and how does it contribute to securing communications in defense networks?

Which action should you take?

Choose only one option

IPsec is used for controlling access to physical locations, not networks

IPsec ensures data integrity in databases, not network traffic

IPsec is used solely for securing email communications

IPsec provides encryption and authentication for IP network traffic, securing communication across the network

Question 2: What is "DNS Spoofing," and how can it be used in an ethical hacking engagement for defense systems?

Which action should you take?

Choose only one option

DNS spoofing involves sending false DNS responses to redirect traffic, potentially compromising sensitive data

DNS spoofing is irrelevant when using secure DNS servers

DNS spoofing only affects public websites and is irrelevant for internal defense systems

DNS spoofing is used to encrypt data traffic, not to intercept it

Question 3: How does the principle of least privilege apply to vulnerability assessments in defense systems?

Which action should you take?

Choose only one option

It assumes that internal users do not need to be assessed for vulnerabilities

It focuses only on network access control and ignores data access policies

It allows unrestricted access for all users to simplify the vulnerability assessment process

It ensures that only the necessary permissions are granted to users and systems, reducing the risk of exploitation

Question 4: What is the role of network traffic analysis in preventing cyberattacks on defense networks?

Which action should you take?

Choose only one option

It is used only for monitoring bandwidth usage and network performance

Network traffic analysis helps identify anomalies and suspicious patterns that may indicate a breach or attack

It focuses on detecting hardware failures rather than cyber threats

It is irrelevant as long as firewalls are in place

Question 5: What is the primary function of the "Defense in Depth" strategy in network security for defense environments?

Which action should you take?

Choose only one option

To improve user authentication processes and reduce the risk of breaches

To implement multiple layers of security controls to protect the network at different levels

To minimize the number of entry points into the network

To ensure that only authorized personnel can access sensitive information

Question 6: What is the role of Network Address Translation (NAT) in enhancing network security?

Which action should you take?

Choose only one option

It compresses network data to improve transfer speeds

It prevents unauthorized network access by blocking external devices

It encrypts network traffic to ensure data security

It hides internal IP addresses and provides a layer of obfuscation between the internal and external network
