NEW QUESTION # 119
What is a role of the network architect?
Answer: D
Explanation:
A network architect is a professional responsible for designing and implementing computer networks that meet the needs of an organization. Here are the key aspects of their role:
1.Designing Networks: Network architects create network infrastructures that support an organization's goals.
They work with both hardware and software components to plan and design data communication networks.
These networks can range from smaller local area networks (LANs) to larger wide area networks (WANs) and intranets.
2.Installation and Implementation: Once the network design is complete, network architects oversee the installation and implementation process. They ensure that routers, modems, cables, and other necessary hardware and software are properly set up. They also determine the layout of network components within buildings or across cities and countries.
3.Security Management: Network architects play a crucial role in managing information and network security.
They implement security measures to protect the network from unauthorized access, data breaches, and other threats.
4.Upgrades and Maintenance: These professionals continuously monitor the network's performance and assess future needs. They perform upgrades to hardware and software as required. Regular maintenance and minor repairs are essential to keep the network operating smoothly and avoid downtime.
5.Documentation: Network architects maintain thorough documentation of networks, including drawings, descriptions, and configurations. This documentation helps ensure efficient management and troubleshooting.
6.Communication and Collaboration: Network architects often work alongside IT specialists and communicate with management staff. They use their understanding of the organization's business goals to develop network systems that align with those objectives.

NEW QUESTION # 120
Which category of software is protected by copyright laws but is available at no cost?
Answer: C
Explanation:
Freeware is software that is distributed at no monetary cost while still remaining protected by copyright laws.
In Information Technology, freeware is typically fully usable without payment, but the creator or publisher retains ownership and controls the license terms. This means users may be allowed to install and use the software for free, yet they are not automatically allowed to modify the source code, resell it, or redistribute it beyond what the license permits. This distinguishes freeware from public domain software, which has no intellectual property protections and can be used, modified, and redistributed freely. It also differs from shareware, which is often free only as a trial or feature-limited version intended to encourage later purchase.
Closed-source describes whether source code is available, not whether the software is free of charge. Many freeware products are also closed-source, but the key idea in the question is free availability with copyright protection. Therefore, the correct category is freeware.
NEW QUESTION # 121

* Therefore, the correct answer is B. Network.
NEW QUESTION # 122
What is the generation of computing known for the introduction of electronic components that could maintain exactly two states?
Answer: C
Explanation:
The phrase electronic components that could maintain exactly two states refers to digital switching behavior, where a device reliably represents binary values such as 0 and 1. In standard computing history, the second generation is recognized for introducing transistors as the key electronic component replacing vacuum tubes.
Transistors are solid-state switching devices that can operate in two stable states, commonly described as on and off, which aligns directly with binary logic used in digital systems. This made computing hardware more compact, faster, and more reliable than first-generation systems, which relied on vacuum tubes that were bulky, generated significant heat, and failed more often. Transistors also consumed less power, enabling longer operating times and improved machine stability. These improvements helped expand computer usage in business and scientific environments and supported better programming tools, including early high-level languages. While earlier systems also used binary logic, the defining generational shift for stable, efficient two-state solid-state components is the transistor era. Therefore, the correct generation is the second generation.
NEW QUESTION # 123
What is the role of professional associations regarding ethics standards in the IT profession?
Answer: D
Explanation:
1.Providing Valuable Ethical Guidelines to IT Professionals:
oProfessional associations establish codes of ethics and codes of conduct that outline expected behavior for IT professionals.
oThese guidelines address ethical considerations related to privacy, security, honesty, and professional responsibility.
oBy adhering to these standards, IT professionals contribute to the well-being of society and uphold the public good1.
2.Engaging in the Development and Adoption of Industry-Leading Practices:
oAssociations collaborate with industry experts to develop globally-accepted best practices.
oThey promote ethical behavior by disseminating these practices through seminars, conferences, and certification courses.
oBy following these standards, IT professionals ensure the integrity and trustworthiness of their work2.
