NEW QUESTION # 128
What is an important strategy of business continuity planning?
Answer: B
Explanation:
Data mirroring is an important business continuity strategy because it maintains a synchronized copy of data on a separate storage system or site. In Information Technology, mirroring supports rapid recovery by ensuring that if the primary data store fails, an up-to-date replica is available to restore operations. Mirroring may be implemented through storage replication, database replication, or real-time backup technologies, and it is often used for high-availability systems that require minimal data loss. This approach directly supports business continuity goals by reducing recovery time and limiting the recovery point, meaning less data is lost between the failure and the restored system. User authentication and data encryption are critical security controls, but they do not by themselves ensure operational continuity after outages or disasters. Service variety is not a standard continuity strategy term in most IT curricula. Business continuity focuses on redundancy, replication, failover, and recovery processes. Since mirroring creates a continuously updated duplicate of critical data, it is a core strategy used to maintain availability and speed restoration. Therefore, the correct answer is data mirroring.
NEW QUESTION # 129
One database field needs to be restricted to only those values that are single alphanumeric symbols. Which data type should be used?
Answer: A
Explanation:
A field restricted to single alphanumeric symbols should use the character data type because it is designed to store exactly one character. Alphanumeric symbols include letters A through Z and digits 0 through 9, and these are naturally represented as individual characters. In Information Technology and database systems, selecting a character type allows the designer to enforce a fixed length of one, which helps maintain data integrity by preventing longer entries. An integer type is used for whole numbers and would not properly handle letters, while floating point is for decimal values and is also inappropriate for single symbols. A character string type can store multiple characters, which would allow inputs longer than one symbol unless additional constraints are applied. Using the character type is therefore the most direct and standard approach for storing one letter or digit, such as a middle initial, a grade code, or a single-character category label.
Therefore, the correct data type is character.
NEW QUESTION # 130
What is a function of a proxy server?
Answer: D
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 # 131
What is a component of disaster recovery strategies?
Answer: B
Explanation:
Off-site storage is a key component of disaster recovery strategies because it protects critical data from local disasters and facility failures. In Information Technology, disaster recovery focuses on restoring systems, applications, and data after disruptive events such as fires, floods, theft, ransomware, or power failures. If backups are stored only on-site, the same event that damages the primary systems can destroy the backups as well. Off-site storage places backup copies in a physically separate location, reducing the risk of total data loss. It may be implemented through secure tape vaulting, remote backup servers, third-party backup facilities, or cloud-based backup services. Disaster recovery planning typically defines backup schedules, retention periods, recovery procedures, and target recovery goals, such as recovery time objective and recovery point objective. While user authentication supports security and parallel processing relates to performance, they are not core elements that ensure data remains available after a site-level disaster.
Therefore, off-site storage is correctly identified as a component of disaster recovery strategies.
NEW QUESTION # 132
Which translation method converts all source code into machine code for later execution?
Answer: D
Explanation:
A compiler converts an entire source code program into machine code before the program is executed. In Information Technology and programming fundamentals, compilation is a translation process where the compiler reads the full source code, checks syntax and often performs optimization, and then produces an output file such as an executable or object code. This compiled output can be stored and run later without needing to retranslate the source code each time. This approach differs from interpretation, where code is translated and executed step by step at runtime. An assembler translates assembly language into machine code, but it is specific to assembly language rather than general high-level source code. The operating system is system software that manages hardware resources and provides services to applications, but it is not the translation method for converting source code into machine code. Because the question asks for the method that converts all source code into machine code for later execution, the correct answer is compiler.
