WGU Introduction to IT Introduction-to-IT Prüfungsfragen mit Lösungen (Q39-Q44):

39. Frage
What is a characteristic of hot storage?

Antwort: A

Begründung:
Hot storage, often discussed alongside hot sites in disaster recovery, refers to storage and recovery capabilities that are ready for rapid use with minimal delay. In IT disaster recovery terms, hot solutions emphasize high availability and quick restoration, which generally requires modern, high-performance, always-ready equipment and frequent data synchronization. Because hot storage is intended to support fast recovery time objectives, it is typically implemented using advanced storage systems, real-time replication, and automated failover technologies. The other options describe characteristics more aligned with colder approaches.
Infrequent access and slow restoration are associated with cold storage or cold sites, where backups may be archived and recovery takes longer. Using lower-performance equipment also fits cold or warm recovery strategies, where cost savings are prioritized over immediate availability. Hot storage solutions are designed to minimize downtime and data loss, and this generally implies up-to-date, capable infrastructure rather than reduced performance. Therefore, among the options provided, the best characteristic of hot storage is that it typically uses innovative equipment.

41. Frage
What does the following SQL statement produce when executed?
SELECT * FROM Customers
WHERE State = 'Arizona';

Antwort: C

Begründung:
The SQL statement provided is a SELECT query that retrieves data from a table within a database. Here's a breakdown of the statement:
*SELECT *: This part of the query specifies that all columns from the specified table should be returned in the result set.
*FROM Customers: This indicates that the table from which to retrieve the data is named 'Customers'.
*WHERE State = 'Arizona': This is a condition that filters the results to only include rows where the 'State' column contains the value 'Arizona'.
Therefore, when this SQL statement is executed, it will produce a result set that includes all columns for all records in the 'Customers' table where the 'State' is 'Arizona'.
References
*SQL documentation on SELECT statements.
*Database management textbooks and online resources that cover SQL syntax and query execution.

Choose 2 answers

Antwort: A,C

Begründung:
1.Translates human-friendly aliases into IP addresses: DNS serves as the "phone book" of the internet, converting user-friendly domain names (like www.example.com) into numerical IP addresses (such as
192.0.2.1) that computers and network devices use to locate one another on the internet12.
2.Stores IP addresses and aliases in a table on the server: DNS servers maintain records that map domain names to corresponding IP addresses. These records are stored in distributed databases across various DNS servers, ensuring efficient and reliable resolution of domain names1.
