C - Regular vulnerability assessments and penetration testing
D - Windows 10.
Answer: A - SELinux
◉ A company is concerned about the security of its network and
wants to implement a control that will allow only preapproved
software to run on its endpoints. Which control should the company
implement to achieve this goal?
A - Allowlisting
B - Blacklisting
C - Encryption
,D - Multifactor authentication.
Answer: A - Allowlisting

C - Conducting regular vulnerability assessments and penetration
testing
D - Using a web application firewall.
Answer: A - Implementing attestation services
◉ A company is looking to protect sensitive data stored on its
storage devices and ensure that this data is secure from
unauthorized access. The company is looking for a solution that
provides a high level of security and protection for its data. Which

B - Hardware security module (HSM)
C - Two-factor authentication
,D - Measured boot.
Answer: A - Self-encrypting drives
◉ A company is concerned about advanced persistent threats and
targeted attacks on its computer systems. The company wants to
implement a security solution that can detect and respond to any
suspicious activity on its systems. Which security technology meets
the needs of this company?
A - Endpoint detection and response (EDR) software
B - Hardware security module (HSM)
C - Two-factor authentication
D - Antivirus tools.
Answer: A - Endpoint detection and response (EDR) software
◉ An enterprise is deploying a new software application that
requires a cryptographic protocol to secure data transmission. The
application will be used to process sensitive customer information,
and the company wants to ensure that the data is protected during
transmission. Which cryptographic protocol meets the needs of the
enterprise?
A - Transport Layer Security (TLS) with Advanced Encryption
Standard (AES)
B - Secure Sockets Layer (SSL) with Data Encryption Standard (DES)
C - Point-to-Point Tunneling Protocol (PPTP) with Triple Data
Encryption Standard (3DES)
, D - Hypertext Transfer Protocol Secure (HTTPS) with Rivest-Shamir-
Adleman (RSA).
Answer: A - Transport Layer Security (TLS) with Advanced
Encryption Standard (AES)
◉ Which emerging technology has the potential to significantly
impact the security of current encryption methods by making it
possible to quickly solve mathematical problems that are currently
considered difficult or impossible to solve?
A - Quantum computing
B - Blockchain
C - Artificial intelligence (AI)
D - Augmented reality (AR).
Answer: A - Quantum computing
◉ Which public-key cryptosystem uses prime factorization as the
basis for its security?
A - Rivest-Shamir-Adleman (RSA)
B - Digital Signature Algorithm (DSA)
C - Elliptic Curve Digital Signature Algorithm (ECDSA)
D - Diffie-Hellman (DH).
Answer: A - Rivest-Shamir-Adleman (RSA)
