NEW QUESTION # 135
What is a step for considering risk during the planning phase of project management?
Answer: D
Explanation:
Risk planning in project management includes identifying risks and then analyzing and prioritizing them so the team can focus on the most serious threats. A standard step taught in Information Technology project management is prioritizing risks by severity and likelihood. Severity reflects the impact on scope, cost, schedule, security, or quality if the risk occurs, while likelihood reflects the probability of occurrence.
Combining these factors helps create a risk matrix and guides decisions about mitigation strategies, contingency plans, and resource allocation. Comparing project progress to milestones is part of monitoring and controlling during execution, not risk planning. Listing each possible cause of failure is related to risk identification, but on its own it does not complete the analysis step that determines which risks matter most.
Establishing clear and attainable goals is part of initiation and planning, but it is not specifically a risk analysis technique. Because the question asks for a step for considering risk during planning, prioritizing by severity and likelihood is the best match. Therefore, the correct answer is option A.
NEW QUESTION # 136
What is the hardware component that contains soldered parts and slots for other pieces of hardware that can be removed?
Answer: B
Explanation:
The motherboard is the main circuit board in a computer that contains soldered components and provides slots and connectors for removable hardware. In Information Technology hardware fundamentals, the motherboard holds essential components such as chipset circuitry, connectors, and sometimes integrated devices like audio or network controllers. It also provides sockets and slots for components that may be installed or replaced, such as the CPU socket, RAM slots, and expansion slots like PCIe for graphics cards or other add-on cards.
The motherboard includes pathways called buses that enable communication among the processor, memory, storage, and peripheral devices. A hard drive is a storage device and does not serve as the central board for system components. The system clock is a timing mechanism, not a physical board containing multiple slots.
An expansion bus refers to a communication pathway standard, not the full board that hosts multiple connectors and soldered parts. Therefore, the component described is the motherboard.
NEW QUESTION # 137
What is the term used to describe additional requirements that are added after project initiation?
Answer: D
Explanation:
In project management, scope creep refers to the uncontrolled expansion of a project's scope beyond its original boundaries. Here's a breakdown:
1.Project Initiation:
oProject initiation is the first step in starting a new project.
oDuring this phase, you establish why you're doing the project and what business value it will deliver.
oThe goal is to secure buy-in from key stakeholders based on the project's initial definition.
2.Scope Creep:
oOnce a project is underway, additional requirements or changes may arise.
oThese unplanned additions can lead to scope creep.
oExamples include:
New features requested by stakeholders.
Enhancements beyond the original scope.
Unforeseen requirements emerging during execution.
3.Impact of Scope Creep:
oScope creep can:
Delay the project timeline.
Increase costs due to additional work.
Affect quality if rushed changes are made.
Create frustration among team members.
4.Managing Scope Creep:
oTo prevent scope creep:
Define clear project boundaries during initiation.
Document requirements thoroughly.
Regularly review and assess any proposed changes.
Communicate with stakeholders about trade-offs.

NEW QUESTION # 138
What is a function of a proxy server?
Answer: A
Explanation:
A proxy server serves several essential functions in network communication:
1.Security and Privacy:
oA proxy server acts as a gateway between the user's device and the internet. When a user sends a request (e.
g., accessing a website), it first goes through the proxy server.
oThe proxy server hides the user's IP address, making it difficult for external entities to directly trace the user' s location or identity.
oBy acting as an intermediary, the proxy server provides an additional layer of security, protecting the internal network from potential threats and attacks.
2.Content Filtering and Access Control:
oOrganizations often use proxy servers to control internet access for their employees. The proxy can filter requests based on predefined rules.
oFor example, an organization might block access to certain websites (e.g., social media, gambling sites) or restrict access during work hours.
oContent filtering helps maintain productivity and prevent unauthorized access to inappropriate or harmful content.
3.Caching and Acceleration:
oProxy servers can cache frequently accessed web pages, images, and files. When a user requests the same content again, the proxy serves it from its cache.
oCaching reduces the load on the internet connection and speeds up access to commonly visited sites.
oIt also helps save bandwidth by minimizing redundant data transfers.
4.Load Balancing:
oIn large networks, multiple proxy servers can distribute incoming requests to different web servers. This load balancing ensures efficient utilization of resources.
oBy evenly distributing traffic, proxy servers prevent any single server from becoming overwhelmed.
5.Anonymity and Geolocation Bypass:
oSome users use proxy servers to hide their real IP addresses. This anonymity can be useful for privacy reasons or to bypass geolocation restrictions.
oFor example, a user in one country can use a proxy server located in another country to access region- restricted content.
