1. An organization recently had an attack that resulted in system data loss. The
system administrator must now restore the system with a data backup. What
functional security control was the system administrator able to implement?
A.Preventative
B.Responsive
C.Corrective
D.Compensating: C.Corrective
The system administrator used a corrective control after the attack. A good example of a corrective control is a backup
system that can restore data that an attacker damages during an intrusion.
Preventative controls act to eliminate or reduce the likelihood that an attack can succeed. A preventative control
operates before an attack can take place.
Responsive controls serve to direct corrective actions enacted after the organization confirms the incident. They often
document these actions in a playbook.
The compensating control is a substitute for a principal control, as recommended by a security standard, and attords
the same (or better) level of protection but uses a ditterent methodology or technology.
2. A security engineer installs a next-generation firewall on the perimeter of a
network. This installation is an example of what type of security control class?
A.Managerial
B.Operational
C.Detective
D.Technical: D.Technical
Firewalls, antivirus software, and operating system (OS) access control models are examples of technical controls. The
engineer would implement technical control as a system (hardware, software, or firmware).
The managerial control gives oversight of the information system. Examples could include risk identification or a tool
allowing the evaluation and selection of other security controls.
People primarily implement operational control rather than systems. For example, security guards and training

programs are operational controls rather than technical controls.
The detective control is a functional control that is not a security control class.
3. An engineer is considering appropriate risk responses using threat mod-
eling. They are trying to understand which threat actors are in scope for
their organization. How does threat modeling identify the principal risks and
tactics, techniques, and procedures (TTPs) for which their system may be
susceptible? (Select the three best options.)
A. By evaluating the system from an attacker's point of view
B. By evaluating a system from a neutral perspective
C. Through using tools such as diagrams
D. By analyzing the system from the defender's perspective: A C D
Evaluating systems from a neutral perspective is not a method used in threat modeling.
4. A mission-critical system is offline at an organization due to a zero-day
attack. The associated software vendor plans to release a patch to remediate
the vulnerability. Which of the following are important patch management
considerations for this scenario? (Select the three best options.)
A.A patch test environment
B.Immediate push delivery of critical security patches
C.A specific team responsible for reviewing vendor-supplied newsletters and
security patch bulletins
D.A routine schedule for the rollout of noncritical patches: A B C
D. While creating a routine schedule for the rollout of noncritical patches has merit, it does not illustrate important
patch management considerations in this example. A security analyst would address noncritical patches at a later
time.
5. A security analyst is reviewing an announcement from the Cybersecurity
and Infrastructure Security Agency. Which source of defensive open-source
intelligence (OSINT) does the agency represent?
A.CERT
B.Internal sources

PRACTICE QUESTIONS AND CYBERSECURITY CONCEPTS REVIEW LATEST VERSION
C.Government bulletins
D.CSIRT: C. Government bulletins
The government is responsible for protecting the country's constituents and the national infrastructure and publishing
various information and advice regarding observed threats. For example, the Department of Homeland Security
and the Cybersecurity and Infrastructure Agency publishes several types of cybersecurity guidance, including basic
informational content and binding operational directives that federal agencies must implement.
A computer emergency response team (CERT) aims to mitigate cybercrime and minimize damage by responding to
incidents quickly.
It is important to consider that evidence regarding active threats, reconnaissance activities, and suspicious behavior
exists within the protected environment.
A computer security incident response team (CSIRT) is a group responsible for responding to security incidents
involving computer systems.
6. Hacktivist: such as Anonymous, WikiLeaks, or LulzSec, use cyber weapons to promote a political agenda.
Hacktivists might attempt to obtain and release confidential information to the public domain, perform denial of
service (DoS) attacks, or deface websites.
7. Nation-state: actors have participated in many attacks, particularly on energy and electoral systems. The
goals of nation-state actors are primarily espionage and strategic advantage.
8. A computer emergency response team (CERT) is quickly reacting to an attack
on the network infrastructure of a semiconductor manufacturer. What is true
about a CERT? (Select the three best options.)
A.CERTS mitigate cybercrime.
B.CERTS work with local law enforcement.
C.CERTS provide knowledge of trending attacks.
D.CERTS publish a wide variety of information concerning threats.: A B C
D. The government is responsible for protecting the country's constituents and the national infrastructure and
publishing various information and advice regarding observed threats. For example, the Department of Homeland
Security and the Cybersecurity and Infrastructure Agency publishes several types of cybersecurity guidance.

9. A systems administrator is searching for potential vulnerabilities in the
network. Which threat-hunting focus area should the administrator examine,
as attackers often exploit it through connected systems or physical access?
A.Isolated networks
B.Misconfigured systems
C.Business-critical assets
D.Lateral movements: Isolated networks, such as air-gapped networks or networks with limited connectiv-
ity to the internet, are often thought to be more secure. However, attackers can still target these networks by exploiting
vulnerabilities in connected systems or through physical access.
10. CSIRT: computer security incident response team (CSIRT) is a group responsible for responding to security
incidents involving computer systems.
11. A system technician reviews system logs from various devices and notices
discrepancies between recorded events. The events between the systems
are not synchronizing in the correct order. Which configuration should the
technician analyze and adjust to ensure proper and accurate logging? (Select
the two best options.)
A.NTP
B.GPS
C.PKI
D.SSL: A.NTP
B.GPS
Time drift or time discrepancies can cause the system to create logs with incorrect time stamps. A time source can
provide accuracy by using the Network Time Protocol (NTP) on the systems.
Global Positioning System (GPS) is a location-providing technology. GPS does have the ability to provide time
synchronization to a system while providing location coordinates.
Public key infrastructure (PKI) is a technology that provides a suite of tools designed to support public/private key
management, integrity checks via digital signatures, and authentication. It does not provide time synchronization
services.
