최신 CompTIA DataSys+ DS0-001 무료샘플문제 (Q39-Q44):

질문 # 39
Which of the following is most likely to prevent tampering with server hardware that houses data?

A. Biometric locks
B. Network firewall
C. Strong password policy
D. Surveillance cameras

정답：A

설명：
The option that is most likely to prevent tampering with server hardware that houses data is biometric locks.
Biometric locks are devices that use biological characteristics, such as fingerprints, facial recognition, iris scan, etc., to control access to a physical location or resource. Biometric locks help prevent tampering with server hardware that houses data by restricting unauthorized entry or theft of the hardware by intruders or attackers. Biometric locks also provide higher security and convenience than other types of locks, such as keys or passwords, which can be lost, stolen, or forgotten. The other options are either not related or not effective for this purpose. For example, a strong password policy is a set of rules or standards for creating and managing passwords for user accounts or systems; a network firewall is a device or software that controls the incoming and outgoing traffic on a network based on a set of rules or policies; surveillance cameras are devices that capture and record video footage of a physical location or resource.

질문 # 40
(A company's database was hacked. A security officer conducted an audit and discovered that an attacker used a rainbow table to break into one of the user accounts to access the database. Which of the following is the best immediate response to this attack?)

A. Implementation of security policies and procedures
B. Security and awareness training
C. Password hash salting
D. Strong passwords

정답：C

설명：
The correct answer is D. Password hash salting. According to CompTIA DataSys+ objectives, rainbow table attacks specifically target hashed passwords by using precomputed hash values to quickly reverse weak or unsalted hashes back into their original plaintext passwords. If an attacker successfully used a rainbow table, it strongly indicates that the database stored password hashes without proper salting or used weak hashing algorithms.
Password salting is a defensive technique where a unique random value (the salt) is added to each password before hashing. This ensures that even if two users have the same password, their resulting hashes are different. More importantly, salting renders rainbow tables ineffective because the attacker would need to generate a separate rainbow table for every possible salt value, which is computationally impractical.
DataSys+ highlights salting as a critical immediate control to protect stored credentials once a password compromise is identified.
Option C, strong passwords, is a preventative control but not the best immediate response. Even strong passwords can be compromised if hashes are unsalted and exposed. Option A, security and awareness training, addresses user behavior but does not mitigate the technical weakness exploited in this attack. Option B, implementing security policies and procedures, is important for long-term governance but does not directly stop rainbow table attacks against existing password hashes.
CompTIA DataSys+ emphasizes that when credential storage mechanisms are compromised, administrators must prioritize cryptographic protections at the database level. This includes salting, using strong hashing algorithms, and forcing credential resets. Among the options provided, password hash salting is the most direct and effective response to prevent the same attack vector from succeeding again.
Therefore, the best immediate response is D. Password hash salting, making it the verified and correct answer aligned with CompTIA DataSys+ guidance.

질문 # 41
Which of the following transactions is allowed in a shared lock?

A. Read
B. Update
C. Insert
D. Delete

정답：A

질문 # 42
Which of the following is a potential issue raised by enterprise database users?

A. The need for concurrent access and multiuser updates
B. The need for multiple views or windows into the same database
C. The need to manually transfer records to paper
D. The need to manage long transactions

정답：A

설명：
A potential issue raised by enterprise database users is the need for concurrent access and multiuser updates. Concurrent access means that multiple users can access the same data at the same time, while multiuser updates mean that multiple users can modify the same data at the same time. These features are essential for enterprise database users who need to share and collaborate on data in real time. However, they also pose challenges such as maintaining data consistency, preventing conflicts or errors, and ensuring transaction isolation and durability. The other options are either not issues or not specific to enterprise database users. For example, the need for multiple views or windows into the same database may be a preference or a convenience, but not an issue; the need to manage long transactions may be a challenge for any database user, not just enterprise ones; the need to manually transfer records to paper may be an outdated or inefficient practice, but not an issue.

질문 # 43
Which of the following cloud delivery models has the most limitations for user access to the underlying infrastructure?

A. DBaaS
B. SaaS
C. PaaS
D. IaaS

정답：B

설명：
Software as a Service (SaaS) provides applications managed by the provider, offering the least access to the underlying infrastructure for users.
