This is an example of:
- A. a flowchart.
- B. pseudocode.
- C. an assembly.
- D. looping.
正解：B
解説：
The example given is an example of pseudocode.
Pseudocode is a way of writing the logic of a program or an algorithm in a simplified and informal language that resembles natural language or code, but does not follow the syntax or rules of a specific programming language.
Pseudocode is often used to plan, design, or explain a program or an algorithm before writing the actual code.
A flowchart is a way of representing the logic of a program or an algorithm using symbols and arrows that show the sequence of steps and decisions.
A flowchart is often used to visualize, analyze, or document a program or an algorithm. Looping is a way of repeating a set of statements or actions in a program or an algorithm until a certain condition is met.
Looping is often used to perform iterative tasks, such as counting, searching, or sorting. An assembly is a way of writing the instructions of a program or an algorithm in a low-level language that corresponds to the machine code of a specific processor.
An assembly is often used to create programs that run fast and efficiently, but it is difficult to read and write.

質問 # 88
Which of the following describes the concept of a database record?
- A. A collection of rows, columns, and constraints
- B. A collection of schemas within the same database
- C. A collection of fields about the same object
- D. A collection of tables within different schemas
正解：C
解説：
The concept of a database record is best described as a collection of fields about the same object. A database record is a row in a table that represents an instance of an entity, such as a customer, an order, a product, etc. A database record consists of one or more fields that store data about the attributes of the entity, such as name, address, phone number, quantity, price, etc. A database record can be uniquely identified by a primary key, which is a field or a combination of fields that do not repeat in the table. A collection of rows, columns, and constraints is not the concept of a database record, but rather the concept of a database table. A database table is a structure that organizes data into rows and columns. Each row represents a record, and each column represents a field. A database table can have constraints that define the rules and restrictions for the data in the table, such as primary keys, foreign keys, unique keys, check constraints, etc. A collection of schemas within the same database is not the concept of a database record, but rather the concept of a database instance. A database instance is a set of memory structures and processes that manage and access a database. A database instance can contain one or more schemas, which are collections of objects that belong to a user or an application in the database, such as tables, views, indexes, etc. A collection of tables within different schemas is not the concept of a database record, but rather the concept of a database relationship. A database relationship is a connection between two tables that share common data. A database relationship can be established by using foreign keys, which are fields that reference the primary keys of another table. A database relationship can be one-to-one, one-to-many, or many-to-many depending on how many records in each table are related to each other.

Which of the following authorization techniques is used to assign permissions and authorize a user based on job title or function?
- A. Role-based access control
- B. Discretionary access control
- C. Mandatory access control
- D. Rule-based access control
正解：A
解説：
Explanation
Role-based access control is the authorization technique that is used to assign permissions and authorize a user based on job title or function. Role-based access control is a security method that defines roles for users or groups and assigns permissions for each role based on their responsibilities or tasks. Role-based access control simplifies the management of user access rights by allowing administrators to grant or revoke permissions based on roles rather than individual users.

質問 # 93
A technician is having trouble connecting multiple users' laptops to the internet wirelessly. The users are on the west side of the building, which is hardwired. Which of the following should the technician do to resolve this issue quickly?
- A. Add an access point for the users.
- B. Replace the users' laptops with desktop computers.
- C. Add a switch and hardwire the users' laptops.
- D. Add a network router.
正解：A
解説：
Explanation
The best solution for the technician to resolve the issue quickly is to add an access point for the users. An access point is a device that provides wireless connectivity to the network. An access point can be connected to a wired network and extend its coverage to wireless devices, such as laptops, smartphones, or tablets. By adding an access point on the west side of the building, the technician can enable the users' laptops to connect to the internet wirelessly without changing their hardware or software settings. Adding a switch and hardwiring the users' laptops is not a quick solution, as it would require installing cables and configuring the network settings on each laptop. Adding a network router is not necessary, as a router is a device that connects multiple networks and routes traffic between them. A router does not provide wireless connectivity by itself, unless it has a built-in access point. Replacing the users' laptops with desktop computers is not a feasible solution, as it would incur high costs and inconvenience for the users.

質問 # 94
The IT department has established a new password policy for employees. Specifically, the policy reads:
Passwords must not contain common dictionary words
Passwords must contain at least one special character.
Passwords must be different from the las six passwords used.
Passwords must use at least one capital letter or number.
Which of the following practices are being employed? (Select TWO).
- A. Password expiration
- B. Password age
- C. Passwords history
- D. Password length
- E. Password complexity
- F. Password lockout
正解：C、E
解説：
Password complexity and password history are two practices that are being employed by the IT department to establish a new password policy for employees. Password complexity is the requirement that passwords must contain a combination of different types of characters, such as letters, numbers, and symbols. Password complexity makes passwords harder to guess or crack by attackers. Password history is the record of the previous passwords used by a user. Password history prevents users from reusing the same passwords over and over again, which reduces the risk of compromise.

質問 # 95
Which of the following categories describes commands used to extract information from a database?
- A. DDR
- B. DML
- C. DLL
- D. DDL
正解：B
解説：
DML stands for Data Manipulation Language, which is a category of commands used to extract information from a database, such as SELECT, INSERT, UPDATE, and DELETE. These commands allow a programmer to query, modify, and delete data from tables and views in a database. DDL stands for Data Definition Language, which is a category of commands used to create and modify the structure of a database, such as CREATE, ALTER, and DROP. These commands allow a programmer to define tables, views, indexes, and other objects in a database. DDR stands for Data Recovery Language, which is not a standard category of commands in SQL (Structured Query Language), the most common language for interacting with databases. DLL stands for Dynamic Link Library, which is not related to databases at all. It is a file format that contains executable code and resources that can be used by multiple applications on Windows operating systems.

質問 # 97
Which of the following best describes when lo use an array?
- A. The user needs one object to store numbers only.
- B. The user needs the object to store one value and to be changeable.
- C. The user needs the object to store one value permanently.
- D. The user needs to store multiple values in one object.
正解：D
解説：
Explanation
The best description of when to use an array is when the user needs to store multiple values in one object. An array is a data structure that can store multiple values of the same data type in an ordered sequence. An array can be accessed or modified by using an index or a position number that indicates the location of each value in the array. An array can be useful when the user needs to store multiple values in one object that can be easily manipulated or iterated over by using loops or functions. The user does not need the object to store one value and to be changeable when using an array, but rather when using a variable. A variable is a data structure that can store one value of any data type in memory. A variable can be accessed or modified by using an identifier or a name that represents the value in the variable. A variable can be useful when the user needs to store one value in an object that can be easily changed or reused throughout the program. The user does not need one object to store numbers only when using an array, but rather when using a numeric data type. A numeric data type is a category of data that can store numbers in various formats or ranges, such as integers, floating-point numbers, complex numbers, etc. A numeric data type can be useful when the user needs one object to store numbers only that can be used for calculations or comparisons in the program.

- A. least privilege
- B. single-factor authentication
- C. biometrics
- D. multifactor authentication
正解：B
解説：
Single-factor authentication is a method of verifying a user's identity by using only one piece of information, such as a username and password. Biometrics, multifactor authentication, and least privilege are not examples of single-factor authentication. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 304.

- A. Data restoration
- B. Restoring access
- C. Redundant power
- D. Disaster recovery
正解：C
解説：
Explanation
Redundant power is the best example of fault tolerance among the given business continuity concepts. Fault tolerance refers to the ability of a system to continue functioning despite failures or errors in some of its components. Redundant power provides backup sources of electricity in case of power outages or surges, ensuring uninterrupted operation of critical systems. Data restoration refers to the process of recovering lost or corrupted data from backups or other sources. Disaster recovery refers to the plan and procedures for restoring normal business operations after a major disruption, such as a natural disaster or a cyberattack.

質問 # 102
Joe, a developer, is writing a program in which he needs to store a number that changes over the duration of the program's run. Which of the following would Joe MOST likely use to accomplish this?
- A. Constant
- B. Loop
- C. Variable
- D. Function
正解：C
解説：
A variable is a named memory location that can store a number or any other type of data that changes over the duration of the program's run. A variable can be assigned a value, modified, or used in calculations or operations. A variable is different from a constant, which is a fixed value that does not change. A variable is also different from a loop, which is a control structure that repeats a block of code until a condition is met. A variable is also different from a function, which is a named block of code that performs a specific task and can be reused12.
