Preview Questions Cybersecurity Specialist (Defense) | Role Specific Skill

Question 1: How does the use of multi-factor authentication (MFA) enhance network security in a defense environment?

Which action should you take?

Choose only one option

It relies only on usernames and passwords, increasing ease of access

It adds an extra layer of authentication, reducing the risk of unauthorized access

It does not have a significant impact on network security

It simplifies login procedures for users and reduces operational overhead

Question 2: How does DNSSEC (Domain Name System Security Extensions) help secure defense network infrastructure?

Which action should you take?

Choose only one option

It eliminates the need for firewalls in securing DNS traffic

It allows for anonymous DNS queries without revealing users' identities

It ensures that all DNS queries are encrypted and hidden from attackers

It protects against DNS spoofing and cache poisoning attacks by adding cryptographic signatures to DNS data

Question 3: What is the purpose of implementing a risk register in defense cybersecurity management?

Which action should you take?

Choose only one option

To document and track identified risks, their assessments, mitigation actions, and outcomes to ensure continuous risk management

To store system configurations without reference to risk or mitigation strategies

To list all systems and assets without linking them to specific risks

To track the number of users accessing the network

Question 4: What is the primary purpose of a Defense-in-Depth strategy in network security for defense systems?

Which action should you take?

Choose only one option

To rely solely on intrusion detection systems (IDS) to protect the network

To use a single security tool for both external and internal network protection

To focus only on perimeter defense while ignoring internal threats

To create multiple layers of defense to protect against advanced persistent threats and mitigate risks

Question 5: How does "Automated Vulnerability Management" improve the efficiency of vulnerability assessments in defense environments?

Which action should you take?

Choose only one option

It is only useful for smaller organizations, not large defense contractors

It focuses only on reducing false positives, not on detecting vulnerabilities

It eliminates the need for manual assessments, reducing overall security effectiveness

It automates the discovery, reporting, and prioritization of vulnerabilities, allowing for faster responses and remediation

Question 6: What is the primary role of the OAuth 2.0 protocol in securing access control in aerospace defense applications?

Which action should you take?

Choose only one option

It allows secure, delegated access to resources without sharing credentials, using tokens for authentication

It encrypts data traffic between users and servers to ensure confidentiality

It uses public key infrastructure to authenticate devices

It verifies the integrity of system files in a secured environment
