Free Practice Questions for CompTIA SY0-701 Exam

Within an organization's Software Development Life Cycle (SDLC), an Information Security Policy is a vital component. It outlines the rules and procedures for ensuring that the organization’s IT assets and data are protected throughout the development process. Ensuring secure coding practices, access controls, and regular security testing is fundamental in preventing vulnerabilities in applications.

Other options like service-level agreements and branch protection requirements are less likely to be integral to SDLC processes. Penetration testing methodology, while useful, is generally considered outside the scope of the SDLC​​.

A site survey is the formal process used to determine the required number, placement, and configuration of wireless access points (APs). Security+ SY0-701 states that site surveys measure RF propagation, identify dead zones, account for building materials, detect interference sources, and evaluate coverage overlap. This information allows network engineers to deploy the fewest APs necessary while still ensuring full coverage.

Although heat maps (C) are generated as a result of a site survey, they are visualization tools—not the actual survey process. A signal locator (A) is not a standardized tool in wireless planning. WPA3 (B) is a wireless security protocol and has no impact on access point planning or coverage optimization.

A full site survey ensures optimal AP placement to balance coverage, performance, and cost—exactly the concern described in the scenario.

Thus, the correct answer is D: Site survey.

The scenario describes a large number of unsolicited emails sent to multiple users. This is characteristic of phishing, which SY0-701 defines as mass-distributed fraudulent messages designed to trick recipients into clicking malicious links, downloading malware, or divulging sensitive information.

Phishing campaigns typically involve:

High volume

Non-targeted messaging

Use of spoofed addresses or fake content

Delivery through email systems

A watering-hole attack (A) compromises a legitimate website frequented by targets—not email. Typosquatting (B) relies on malicious websites with deceptive URLs. Business Email Compromise (C) involves highly targeted spear-phishing or impersonation attacks, not bulk email blasts.

Because this incident involves “hundreds of messages” delivered to “multiple users,” it clearly matches the characteristics of a phishing attack, not a sophisticated targeted attack type.

Phishing is the most common form of social engineering and is emphasized heavily in the Security+ exam due to its frequency and effectiveness.

An intrusion prevention system (IPS) is a security device that monitors network traffic and blocks or modifies malicious packets based on predefined rules or signatures. An IPS can prevent attacks that exploit known vulnerabilities in older browser versions by detecting and dropping the malicious packets before they reach the target system. An IPS can also perform other functions, such as rate limiting, encryption, or redirection. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 3: Securing Networks, page 132.

An air-gapped network is a network that is physically isolated from other networks, such as the internet, to prevent unauthorized access and data leakage. However, an air-gapped network can still be compromised by removable devices, such as USB drives, CDs, DVDs, or external hard drives, that are used to transfer data between the air-gapped network and other networks. Removable devices can carry malware, spyware, or other malicious code that can infect the air-gapped network or exfiltrate data from it. Therefore, removable devices are the most common data loss path for an air-gapped network. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 9: Network Security, page 449 1

File Integrity Monitoring (FIM) is the best tool for detecting unauthorized file deletions, modifications, or improper permission changes within network shares. FIM works by creating cryptographic hashes and baselines for protected files or directories and then continuously monitoring for deviations. Any unauthorized deletion, modification, or permission change triggers alerts.

Security+ SY0-701 identifies FIM as a foundational integrity control used in compliance frameworks (PCI-DSS, HIPAA) and operational security monitoring. Because the organization is experiencing unpredictable changes to shared files and permissions, FIM provides visibility and accountability for who changed what and when.

DLP (A) prevents data leakage but does not detect permission changes. EDR (B) focuses on endpoint threat behavior, not file integrity on network shares. ACLs (D) define permissions but do not track changes or detect unauthorized modifications.

Therefore, C: FIM is the correct choice.

When hosting an on-premises software application in a cloud-based service, ensuring visualization and isolation of resources is crucial for maintaining security best practices. This involves using virtualization techniques to create isolated environments (e.g., virtual machines or containers) for different applications and services, reducing the risk of cross-tenant attacks or resource leakage.

Network segmentation is important but pertains more to securing network traffic rather than isolating computing resources.

Data encryption is also essential but doesn’t specifically address resource isolation in a cloud environment.

Strong authentication policies are critical for access control but do not address the need for isolating resources within the cloud environment​​.

The best first step is to reviewpatching (A). Outdated OS versions often contain vulnerabilities that can be exploited by malware. Ensuring systems are up-to-date is a foundational cybersecurity practice.

This is highlighted inDomain 2.1: Given a scenario, analyze indicators of malicious activityandDomain 2.2, emphasizing the importance of“Patching” as part of system hardening and mitigation strategy.

Comprehensive and Detailed In-Depth Explanation:

AWeb Application Firewall (WAF)is designed toprotect web applications from attackssuch asCross-Site Scripting (XSS)by filtering and monitoring HTTP traffic between the internet and a web application.

Next-Generation Firewalls (NGFW) (A)provide advanced network security but are not specifically designed to protect web applications from XSS attacks.

Unified Threat Management (UTM) (B)provides multiple security functions but lacks the specialized application-layer protection needed to mitigate XSS.

Network Access Control (NAC) (D)controls device access to the network but does not prevent web-based attacks.

AWAF is the best solutionfor protecting web servers fromXSS, SQL injection, and other web-based threats.
