CompTIA Updated SY0-701 Exam Questions and Answers by harlen

The best answer is C. WAF.

XSS (Cross-Site Scripting) is a web application attack that injects malicious scripts into web content. A WAF (Web Application Firewall) is specifically designed to inspect, filter, and block malicious HTTP and HTTPS traffic targeting web applications. It can help detect and prevent common attacks such as XSS, SQL injection, and other application-layer threats.

Why the other options are incorrect:

A. NGFWA next-generation firewall provides advanced network security features, but it is not as specifically focused on web application attacks as a WAF.

B. UTMUnified Threat Management combines multiple security features in one platform, but it is not the best answer for preventing a web application attack like XSS.

D. NACNetwork Access Control focuses on controlling which devices can connect to the network. It does not directly prevent XSS.

From the SY0-701 perspective, attacks against web applications are best mitigated by controls specifically designed for application-layer inspection, making WAF the correct answer.

The best answer is A. 2.

ARO (Annualized Rate of Occurrence) measures how many times an incident is expected to occur per year.

The company expects:

10 incidents

over 5 years

So the calculation is:

ARO = 10 / 5 = 2

This means the expected annual rate of occurrence is 2 incidents per year.

Why the other options are incorrect:

B. 5This would not represent the yearly average based on the numbers given.

C. 10This is the total number of incidents over five years, not the annualized value.

D. 50This is not supported by the information in the question.

From a Security+ risk calculation standpoint, when a total event count is spread across multiple years, the ARO is found by dividing the total incidents by the number of years. Therefore, A is correct.

If email filtering tools are not tuned based on reported emails, malicious emails will continue to bypass filters. Effective filtering depends on feedback and updating rules with real threat data.

Flagging legitimate emails (A) would cause false positives, shadow IT (C) and forwarding personal emails (D) are less relevant to the filtering bypass.

Tuning email filters is part of continuous Security Operations processes【6:Chapter 14†CompTIA Security+ Study Guide】.
