Which of the following are benefits of a security awareness training program9 (Select two).
- A. Increases the availability of computers
- B. Provides information on how to avoid phishing
- C. Lowers the incidence of hardware failures
- D. Enhances overall security
- E. Creates IT security opportunities for end users
- F. Advances end users' technical skills
正解：B、D
解説：
The benefits of a security awareness training program are enhancing overall security and providing information on how to avoid phishing. Enhancing overall security is a benefit of a security awareness training program because it helps users understand the importance and value of security for themselves and their organization. It also helps users develop good security habits and behaviors, such as choosing strong passwords, locking their devices, reporting incidents, etc., which can prevent or reduce security risks and threats. Providing information on how to avoid phishing is a benefit of a security awareness training program because it helps users recognize and respond to phishing attacks, which are one of the most common and effective types of social engineering attacks. Phishing attacks involve sending fraudulent emails or messages that appear to come from legitimate sources to trick recipients into clicking on malicious links or attachments, or providing personal or financial information. A security awareness training program can teach users how to identify phishing signs, such as spelling errors, generic greetings, urgent requests, etc., and how to verify the sender, the URL, or the attachment before opening or responding. Lowering the incidence of hardware failures is not a benefit of a security awareness training program, but rather a benefit of a hardware maintenance program. A hardware maintenance program involves performing regular checks and repairs on the physical components of a system or network, such as disks, memory, CPU, power supply, etc., to ensure their proper functioning and performance. A hardware maintenance program can prevent or reduce hardware failures, which can cause data loss, corruption, or interruption for the system or network and its users. Increasing the availability of computers is not a benefit of a security awareness training program, but rather a benefit of a backup and recovery program. A backup and recovery program involves creating and restoring copies of data or systems in case of data loss, corruption, or disaster. A backup and recovery program can increase the availability of computers by ensuring that users can access their data or systems from alternative sources or locations in case of an emergency. Advancing end users' technical skills is not a benefit of a security awareness training program, but rather a benefit of a technical training program. A technical training program involves teaching users how to use various technologies or applications effectively and efficiently. A technical training program can advance end users' technical skills by increasing their knowledge, competence, and productivity with the technologies or applications they use. Creating IT security opportunities for end users is not a benefit of a security awareness training program, but rather a benefit of a career development program. A career development program involves providing users with guidance and resources to help them achieve their professional goals and aspirations. A career development program can create IT security opportunities for end users by exposing them to different IT security roles, paths, or certifications that they can pursue or obtain.

A technician is concerned that sensitive data transmitted over the Internet can be intercepted and viewed during a MITM attack. Which of the following should the technician enable to reduce the risk?
- A. DLP
- B. IPS
- C. TLS
- D. ACL
正解：C
解説：
TLS (Transport Layer Security) is a protocol that should be enabled to reduce the risk of a MITM (man-in-the-middle) attack. A MITM attack is a type of cyberattack where an attacker intercepts and alters the communication between two parties without their knowledge. A MITM attack can compromise the confidentiality, integrity, and authenticity of the data being transmitted. TLS is a protocol that provides encryption, authentication, and integrity for data communication over the Internet. TLS can prevent a MITM attack by encrypting the data to make it unreadable by the attacker, authenticating the identities of the parties to prevent impersonation, and verifying the integrity of the data to detect any tampering.

質問 # 72
Which of the following is the slowest processing speed?
- A. 4MbpS
- B. 3.4MHz
- C. 2.6GHz
- D. 5000Kbps
正解：B
解説：
Processing speed is measured in hertz (Hz), which is the number of cycles per second that a processor can perform. The higher the hertz, the faster the processing speed. There are different units of hertz, such as megahertz (MHz), which is one million hertz, and gigahertz (GHz), which is one billion hertz. Therefore, 3.4MHz is the slowest processing speed among the given options, as it is equivalent to 3.4 million hertz. 2.6GHz is equivalent to 2.6 billion hertz, which is the fastest processing speed among the given options. 5000Kbps and 4Mbps are not units of processing speed, but units of data transfer rate, which measure how much data can be transmitted over a network in a given time. Kbps stands for kilobits per second, and Mbps stands for megabits per second. One megabit is equal to 1000 kilobits, so 4Mbps is equivalent to 4000Kbps.

質問 # 78
Which of the following describes the concept of a database record?
- A. A collection of schemas within the same database
- B. A collection of tables within different schemas
- C. A collection of rows, columns, and constraints
- D. A collection of fields about the same object
正解：D
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.

When following the troubleshooting methodology, which of the following should be performed last?
- A. Determine the cause.
- B. Establish a plan.
- C. Document findings.
- D. Verify functionality.
正解：C
解説：
The troubleshooting methodology is a systematic process of identifying and resolving problems with computers or other devices. The troubleshooting methodology consists of six steps: identify the problem, establish a theory of probable cause, test the theory to determine cause, establish a plan of action to resolve the problem and implement the solution, verify full system functionality and if applicable implement preventive measures, document findings/actions/outcomes. The last step of the troubleshooting methodology is to document findings/actions/outcomes. This step involves recording what was done to solve the problem, what was learned from the process, what preventive measures were taken (if any), and any feedback from the customer or user. Documenting findings/actions/outcomes is important for several reasons: it helps keep track of what was done and why; it helps avoid repeating the same steps or mistakes in the future; it helps share knowledge and best practices with others; it helps improve customer satisfaction and trust; it helps comply with organizational policies or regulations
