NEW QUESTION # 91
Which of the following have data manipulation and procedural scripting power? (Choose two.)
Answer: C,F
Explanation:
The two options that have data manipulation and procedural scripting power are PL/SQL and T-SQL. PL/SQL, or Procedural Language/Structured Query Language, is an extension of SQL that adds procedural features to SQL for Oracle databases. PL/SQL allows users to create and execute stored procedures, functions, triggers, packages, etc., using variables, loops, conditions, exceptions, etc., in addition to SQL commands. PL/SQL helps improve the performance, functionality, modularity, and security of SQL queries and applications. T-SQL, or Transact-SQL, is an extension of SQL that adds procedural features to SQL for Microsoft SQL Server databases. T-SQL allows users to create and execute stored procedures, functions, triggers, etc., using variables, loops, conditions, exceptions, etc., in addition to SQL commands. T-SQL helps improve the performance, functionality, modularity, and security of SQL queries and applications. The other options are either not related or not having both data manipulation and procedural scripting power. For example, PQL, or Power Query Language, is a data analysis and transformation language for Microsoft Power BI and Excel; Advanced SQL is a term that refers to the advanced features or techniques of SQL, such as subqueries, joins, aggregations, etc.; SQL, or Structured Query Language, is a standard language for manipulating and querying data in relational databases, but it does not have procedural features. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.2 Given a scenario, execute database tasks using scripting and programming languages.
NEW QUESTION # 92
Which of the following best describes the function of a wildcard in the WHEREclause?
Answer: A
Explanation:
A wildcard in the WHERE clause allows pattern matching instead of requiring an exact match when filtering records in a SELECT statement.
NEW QUESTION # 93
A server administrator wants to analyze a database server's disk throughput. Which of the following should the administrator measure?
Answer: A
Explanation:
The factor that the administrator should measure to analyze a database server's disk throughput is IOPS. IOPS, or Input/Output Operations Per Second, is a metric that measures the number of read and write operations that a disk can perform in one second. IOPS indicates the performance or speed of a disk and how well it can handle multiple requests or transactions. Higher IOPS means higher disk throughput and lower latency. IOPS can be affected by various factors, such as disk type, size, speed, cache, RAID level, etc. The other options are either not related or not sufficient for this purpose. For example, RPfvl is not a valid acronym or metric; latency is the time delay between a request and a response; reads are the number of read operations performed by a disk.
NEW QUESTION # 94
Brad is helping to design a disaster recovery strategy for his organization and is analyzing possible storage locations for backup data. He is not certain where the organization will recover operations in the event of a disaster and would like to choose an option that allows them the flexibility to easily retrieve data from any DR site.
Which one of the following storage locations provides the best option for Brad?
Answer: B
NEW QUESTION # 95
(A database administrator wants users to be able to access resources remotely from home. Which of the following best describes how the administrator can enable this access without compromising the security of the stored data?)
Answer: B
Explanation:
The correct answer is A. Implement a virtual private network (VPN). CompTIA DataSys+ emphasizes secure remote access as a critical requirement for modern database environments, especially when users need to connect from untrusted networks such as home internet connections. A VPN provides a secure, encrypted tunnel between the user's device and the organization's internal network, allowing remote users to access database resources as if they were physically on-site.
By using strong encryption and authentication mechanisms, a VPN ensures that data transmitted over public networks cannot be intercepted, read, or altered by unauthorized parties. DataSys+ highlights VPNs as a best practice for protecting data-in-transit and preventing exposure of sensitive database services directly to the internet. VPNs also allow administrators to enforce centralized access controls, logging, and monitoring, further strengthening security.
Option B, implementing strong password policies, is an important security measure but does not by itself enable secure remote connectivity. Password policies address authentication strength, not secure network transport. Option C, configuring and deploying a firewall, is essential for controlling traffic flow, but a firewall alone does not provide secure remote access for home users. It typically blocks or allows connections rather than securely tunneling them. Option D, implementing a perimeter network (DMZ), is designed to host internet-facing services while isolating internal systems. Exposing databases through a perimeter network increases risk and is not recommended for direct user access to internal data.
CompTIA DataSys+ stresses the principle of minimizing attack surface. A VPN supports this principle by avoiding direct exposure of database services while still enabling authorized remote access. It also integrates well with multifactor authentication and identity management systems.
Therefore, the most secure and appropriate method to enable remote access without compromising stored data is to implement a virtual private network, making option A the correct and fully verified answer.
