Certified Cybersecurity Associate PCCET Exam Questions and Answers PDF

Software patches are updates that fix bugs, vulnerabilities, or performance issues in applications. Applying software patches regularly is one of the best practices to secure applications against exploits, as it prevents attackers from taking advantage of known flaws in the software. Software patches can also improve the functionality and compatibility of applications, as well as address any security gaps that may arise from changes in the operating system or other software components. Endpoint security solutions, such as Cortex XDR, can help organizations automate and streamline the patch management process, ensuring that all endpoints are up to date and protected from exploits. References:

According to the NIST definition of cloud computing1, there are three service models for cloud computing: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). In the SaaS model, the cloud provider delivers the software applications over the internet, and the users access them from various devices through a web browser or a program interface. The cloud provider manages the underlying infrastructure, including the servers, databases, and code of the applications. The users do not need to install, update, or maintain the software, and they only pay for the service they use. The scenario described in the question is an example of the SaaS model, as the user is provided access over the internet to an application running on a cloud infrastructure, and the vendor hosts and maintains the servers, databases, and code of that application. References:

SaaS - User responsible for only the data, vendor responsible for rest

 A demilitarized zone (DMZ) is a portion of an enterprise network that sits behind a firewall but outside of or segmented from the internal network1. The DMZ typically hosts public services, such as web, mail, and domain servers, that can be accessed by traffic from the internet1. However, the DMZ is isolated from the internal network by another firewall or security gateway, which prevents unauthorized access to the private network2. Therefore, statements A and D are true about servers in a DMZ, while statements B and C are false. References:
