최신 CompTIA DataSys+ DS0-001 무료샘플문제 (Q85-Q90):

질문 # 85
Which of the following cloud delivery models has the most limitations for user access to the underlying infrastructure?

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

정답：D

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

질문 # 86
Which of the following is the best way to migrate a large data load from one table to another, considering total time and blocking?

A. Split the load size into many transactions.
B. Split the load size in half and run simultaneously.
C. Batch large loads into one transaction.
D. Batch into small loads and run in parallel.

정답：D

설명：
The best way to migrate a large data load from one table to another, considering total time and blocking, is to batch into small loads and run in parallel. This means that the large data load is divided into smaller chunks that can be processed simultaneously by multiple threads or processes. This reduces the total time required for the migration and also minimizes the blocking of other operations on the tables involved. The other options are either less efficient or more prone to blocking. For example, splitting the load size into many transactions may increase the overhead and latency of each transaction; splitting the load size in half and running simultaneously may still cause blocking or contention; batching large loads into one transaction may take longer and lock the tables for longer periods.

질문 # 87
An automated script is using common passwords to gain access to a remote system. Which of the following attacks is being performed?

A. DoS
B. Phishing
C. Brute-force
D. SQL injection

정답：C

설명：
The attack that is being performed is brute-force. A brute-force attack is a type of attack that tries to guess a password or a key by systematically trying all possible combinations of characters or values until the correct one is found. A brute-force attack can use common passwords, such as
"123456", "password", or "qwerty", as well as dictionaries, word lists, or patterns to speed up the process. A brute-force attack can target a remote system, such as a web server, an email account, or a network device, and gain unauthorized access to its data or resources. The other options are either different types of attacks or not related to password guessing. For example, a DoS, or Denial-of-Service, attack is a type of attack that floods a system with requests or traffic to overwhelm its capacity and prevent legitimate users from accessing it; an SQL injection attack is a type of attack that inserts malicious SQL statements into an input field or parameter of a web application to manipulate or compromise the underlying database; a phishing attack is a type of attack that sends fraudulent emails or messages that appear to come from a trusted source to trick users into revealing their personal or financial information.

질문 # 88
A database administrator is new to a company and wants to create a document that illustrates the interaction between tables. Which of the following should the administrator create?

A. Troubleshooting guide
B. Database reference manual
C. Data dictionary
D. Entity relationship diagram

정답：D

설명：
The document that the administrator should create to illustrate the interaction between tables is an entity relationship diagram. An entity relationship diagram (ERD) is a graphical representation of the entities (tables), attributes (columns), and relationships (constraints) in a database. An ERD helps the administrator to visualize the structure and design of the database, as well as the dependencies and associations among the tables. The other options are either different types of documents or not related to the interaction between tables. For example, a troubleshooting guide is a document that provides instructions on how to solve common problems or errors in a database; a data dictionary is a document that describes the metadata (information about data) of a database; a database reference manual is a document that provides information on how to use or operate a database.

질문 # 89
Which of the following is an attack in which an attacker hopes to profit from locking the database software?

A. Ransomware
B. On-path
C. Spear phishing
D. SQL injection

정답：A

설명：
The attack in which an attacker hopes to profit from locking the database software is ransomware. Ransomware is a type of malware that encrypts the data or files on a system or network and demands a ransom from the victim to restore them. Ransomware can target database software and lock its access or functionality until the victim pays the ransom, usually in cryptocurrency. Ransomware can cause serious damage and loss to the victim, as well as expose them to further risks or threats. Ransomware can be delivered through various methods, such as phishing emails, malicious attachments, compromised websites, etc. The other options are either different types of attacks or not related to locking database software at all. For example, spear phishing is a type of phishing attack that targets a specific individual or organization with personalized or customized emails; SQL injection is a type of attack that inserts malicious SQL statements into an input field or parameter of a web application to manipulate or compromise the underlying database; on-path is a type of attack that intercepts and modifies the data in transit between two parties on a network. Reference: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.4 Given a scenario, identify common types of attacks against databases
