WGU Introduction to IT Sample Questions (Q28-Q33):

NEW QUESTION # 28
What is a function of a proxy server?

Answer: B

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.

NEW QUESTION # 31
What is the primary role of the database administrator?

Answer: D

Explanation:
The core responsibility of a database administrator (DBA) centers around managing and optimizing Database Management Systems (DBMS). This includes:
*Installation and Configuration: Setting up new database instances, applying relevant configurations, and ensuring they align with the organization's needs.
*Maintenance: Performing regular backups, security updates, and patch management to keep the databases secure and healthy.
*Performance Analysis: Monitoring database performance, identifying bottlenecks, and implementing optimizations to ensure efficient data retrieval and operations.
*Troubleshooting: Proactively addressing database errors, resolving operational issues, and ensuring data integrity.


NEW QUESTION # 32
What is a priority of business continuity?

Answer: B

Explanation:
A priority of business continuity is maintaining critical system replicas so essential services can continue or be restored quickly after a disruption. In Information Technology and business continuity planning, organizations identify mission-critical systems and ensure there are standby resources such as replicated servers, replicated databases, or mirrored environments that can take over if the primary systems fail. Replicas support rapid recovery and reduced downtime by enabling failover and restoration without rebuilding from scratch. While on-site redundancy can help with minor failures, business continuity typically emphasizes resilience beyond a single location, since a site-wide incident can disable all on-site resources. Extensive black-box testing relates more to software testing methods than continuity priorities, and rapid system development is a software engineering concern, not the central focus of continuity. Critical system replicas may exist as hot, warm, or cold arrangements depending on recovery time objectives, but the underlying priority is ensuring a working copy of vital systems exists for continuity. Therefore, the correct answer is critical system replicas.
