SY0-701 Practice Test

Explanation: In a cloud environment, high availability is typically ensured through the use of a load balancer. A load balancer distributes network or application traffic across multiple servers, ensuring that no single server becomes overwhelmed and that services remain available even if one or more servers fail. This setup enhances the reliability and availability of applications. Load balancer: Ensures high availability by distributing traffic across multiple servers or instances, preventing overload and ensuring continuous availability. Access broker: Typically refers to a service that facilitates secure access to resources, not directly related to high availability. Cloud HSM (Hardware Security Module): Provides secure key management in the cloud but does not specifically ensure high availability.
WAF (Web Application Firewall): Protects web applications by filtering and monitoring HTTP traffic but is not primarily focused on ensuring high availability.

Explanation: The most likely reason the download was blocked, resulting in a false positive, is a misconfiguration in the endpoint protection software. False positives occur when legitimate actions are incorrectly identified as threats due to incorrect settings or overly aggressive rules in the security software.
Misconfiguration in the endpoint protection software: Common cause of false positives, where legitimate activities are flagged incorrectly due to improper settings.
Zero-day vulnerability: Refers to previously unknown vulnerabilities, which are less likely to be associated with a false positive.
Supply chain attack: Involves compromising the software supply chain, which is a broader and more severe issue than a simple download being blocked.
Incorrect file permissions: Would prevent access to files but not typically cause an alert in endpoint protection software.

Explanation: This situation is an example of smishing, which is a type of phishing that uses text messages (SMS) to entice individuals into providing personal or sensitive information to cybercriminals. The best responses to this situation are to add a smishing exercise to the annual company training and to issue a general email warning to the company. A smishing exercise can help raise awareness and educate employees on how to recognize and avoid smishing attacks. An email warning can alert employees to the fraudulent text message and remind them to verify the identity and legitimacy of any requests for information or money.

Explanation: The scenario describes a situation where a user unknowingly triggers an unwanted action, such as changing their password, by clicking a malicious link. This is indicative of a Cross-Site Request Forgery (CSRF) attack, where an attacker tricks the user into executing actions they did not intend to perform on a web application in which they are authenticated. References = CompTIA Security+ SY0-701 study materials, particularly in the domain of web application security and common attack vectors like CSRF.

Explanation: When multiple Wireless Access Points (WAPs) are using similar frequencies with high power settings, it can cause channel overlap, leading to interference and connectivity issues. This is likely the reason why mobile users are unable to access the internet in the lobby. Evaluating and adjusting the channel settings on the WAPs to avoid overlap is crucial to resolving the connectivity problems.
