CompTIA CLO-002 Exam Questions & Answers

Correct Answer: B

The highest utilization is represented by the application server as it has the highest percentage of used space to allocated space. The application server has used 188GB out of 100GB allocated space, which is 188% utilization. The mail server has used 55GB out of 80GB allocated space, which is 68.75% utilization. The file server has used 70GB out of 90GB allocated space, which is 77.78% utilization. The web server has used 105GB out of 130GB allocated space, which is 80.77% utilization.

Correct Answer: BC

Explanation: Geo-redundancy and backup are two methods that can ensure the availability of data that is accessed across multiple sites. Geo-redundancy is the practice of storing data in more than one geographic location, such as different regions, countries, or continents. This can improve the data availability by reducing the impact of natural disasters, network failures, or malicious attacks that may affect one site. Geo-redundancy can also improve the data performance by allowing users to access the data from the nearest or fastest site. Backup is the process of creating and storing copies of data that can be used to restore the original data in case of data loss, corruption, or deletion. Backup can ensure the data availability by providing a way to recover the data from a previous state, such as before a hardware failure, software error, or human error. Backup can also protect the data from accidental or intentional modifications that may compromise its integrity or security. Geo-redundancy and backup are different from other options, such as auto-scaling, provisioning, locality, and zones. Auto-scaling is the ability of a cloud service to automatically adjust the amount of resources allocated to a workload based on the demand or usage. Provisioning is the process of allocating and configuring the resources needed to run a cloud service or application. Locality is the principle of storing data close to where it is used, such as in the same region, country, or jurisdiction. Zones are logical or physical subdivisions of a cloud region that provide isolation and redundancy for the cloud resources. While these options may also affect the data availability, they do not directly address the data access across multiple sites, which is the focus of the question.

Correct Answer: B

Explanation: A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predefined security rules1. A firewall can block or allow connection requests to cloud resources based on the source, destination, port, protocol, or content of the packets2. A firewall can be deployed as a hardware appliance, a software application, or a cloud service3.
