A load balancer best supports the availability requirement because it distributes client traffic across available backend resources and can route traffic away from failed or overloaded systems. When properly implemented with multiple servers or redundant service instances, load balancing improves uptime, resilience, and service continuity. A proxy server forwards requests and may provide filtering or caching, but it does not inherently guarantee application availability. A jump server provides controlled administrative access to internal systems, not client-facing service continuity. Geographic restrictions limit access based on location and may actually reduce availability for some users. Security+ places load balancing under resilient architecture because it helps maintain access when individual systems fail or become saturated.

LDAP authentication on the printer (C)would require users toauthenticate before printing, enablingsecure print release. This ensures that documents arenot printed until the authorized user is physically present, which directly addresses the issue of missing confidential documents.

As perCompTIA Security+ SY0-701, Domain 3.1 (Access management), integratingauthentication mechanisms like LDAPimproves physical and document security in shared environments.

The correct answer is B. Passive.

Passive reconnaissance involves gathering information about a target without directly interacting with the target’s systems. OSINT, or open-source intelligence, includes publicly available information such as websites, social media, job postings, public DNS records, code repositories, breach databases, search engine results, and public documentation.

This aligns with CompTIA Security+ SY0-701 topics related to reconnaissance, penetration testing, threat intelligence, and information gathering.

Why the other options are incorrect:

A. Active

Active reconnaissance involves directly interacting with the target environment, such as port scanning, vulnerability scanning, banner grabbing, or probing services.

C. Offensive

Offensive security refers broadly to activities such as penetration testing and red-team operations. However, it does not specifically describe the reconnaissance method used.

D. Defensive

Defensive security focuses on protecting, monitoring, and responding to threats. OSINT collection at the start of a penetration test is not best described as defensive reconnaissance.

Therefore, checking OSINT resources is passive reconnaissance.

A tabletop exercise is a simulated scenario that tests the organization’s incident response plan and procedures. It involves key stakeholders and decision-makers who discuss their roles and actions in response to a hypothetical incident. It can help identify gaps, weaknesses, and improvement areas in the incident response process. It can also enhance communication, coordination, and collaboration among the participants. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 525 1

Detective controls (such as audit logs, monitoring, and alerts) are specifically designed to identify and reveal unauthorized or malicious activity, including insider manipulation, in systems like payroll. These controls help ensure that any attempts to manipulate data are discovered and investigated.

The best answer is C. Traffic will bypass inspection during a failure.

A firewall configured to fail open will allow traffic to continue flowing if the device crashes or fails. This preserves availability, but it creates a security risk because traffic may pass through without being inspected or filtered.

That means malicious traffic, unauthorized connections, or prohibited traffic could traverse the network during the outage.

Why the other options are incorrect:

A. There may be increased latency during failover.This is not the main security risk associated with fail-open mode.

B. Authentication tokens may be invalidated during an outage.This is unrelated to firewall fail-open behavior.

D. All encrypted traffic will be blocked during an outage.Fail-open does the opposite of blocking traffic; it allows traffic to pass through.

From a SY0-701 perspective, fail-open prioritizes availability, but the tradeoff is that security inspection may be bypassed, making C the correct answer.

Scheduled downtime is a planned period of time when a system or service is unavailable for maintenance, updates, upgrades, or other changes. Scheduled downtime gives administrators a set period to perform changes to an operational system without disrupting the normal business operations or affecting the availability of the system or service. Scheduled downtime also allows administrators to inform the users and stakeholders about the expected duration and impact of the changes. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 12: Security Operations and Administration, page 579 1

The logs show an SQL injection attack. The first step is to verify if new accounts have been created, indicating a successful injection.

=================

Blackmail is the correct motivation because the attacker is coercing the employee by threatening to release sensitive personal files. The attacker is not simply seeking money directly, so financial gain is not the best description. Revenge would involve retaliation for a perceived grievance, but the scenario describes coercion. Espionage involves stealing information for political, corporate, or strategic advantage, which is not the primary driver here. This is a social engineering and insider-risk scenario because an external attacker pressures an internal employee into performing malicious activity. Security+ expects candidates to recognize attacker motivations such as financial gain, ideology, espionage, revenge, and blackmail based on the pressure or incentive being used.

The first step in reducing the number of credentials each employee must maintain when using multiple SaaS applications is to select an Identity Provider (IdP). An IdP provides a centralized authentication service that supports Single Sign-On (SSO), enabling users to access multiple applications with a single set of credentials.

Enabling SAML would be part of the technical implementation but comes after selecting an IdP.

OAuth tokens are used for authorization, but selecting an IdP is the first step in managing authentication.

Password vaulting stores multiple passwords securely but doesn ' t reduce the need for separate logins​​.

CIS benchmarks are the best choice because they provide recognized secure configuration baselines for operating systems, applications, cloud platforms, network devices, and other infrastructure components. A CISO modernizing legacy systems needs a structured way to evaluate current configurations, identify gaps, prioritize weaknesses, and build a risk-based remediation plan. Angry IP Scanner can help discover live hosts, but it does not provide security baselines or modernization guidance. The OWASP Web Security Testing Guide focuses on web application testing, not broad legacy infrastructure. Metasploit is a penetration testing framework and is not the right tool for defining modernization scope. Security+ emphasizes secure baselines, hardening standards, and benchmark-driven configuration review for reducing risk.

The best answer is B. It is used to make access control decisions without inheriting permission decisions from prior events.

In a Zero Trust environment, the core principle is never trust, always verify. A policy engine evaluates each access request using current context and defined security policies. Access is not automatically granted simply because a user or device was previously authenticated or allowed access earlier.

This means decisions are made continuously and based on factors such as:

user identity

device posture

location

requested resource

risk level

session context

The phrase “without inheriting permission decisions from prior events” best reflects the Zero Trust concept that trust is not assumed or permanently granted.

Why the other options are incorrect:

A. It is used by a central server to apply default permissions across a range of network and computing resources.This sounds more like centralized administration, but it does not capture the dynamic, context-based access decision-making of a Zero Trust policy engine.

C. It is used to dynamically assign user permissions based on a user ' s identity and previous activity.This is close, but the wording emphasizes previous activity, whereas Zero Trust focuses on real-time evaluation of current conditions rather than inherited trust.

D. It is used when user roles are unknown and the organization wants to leverage ML to control access.Machine learning may support analytics, but this is not the main purpose of a Zero Trust policy engine.

From the SY0-701 perspective, a policy engine is central to making explicit, context-aware access decisions for every request, which is best captured by B.

 A honey pot is a system or a network that is designed to mimic a real production server and attract potential attackers. A honey pot can be used to identify the attacker’s methods, techniques, and objectives without affecting the actual production servers. A honey pot can also divert the attacker’s attention from the real targets and waste their time and resources12.

The other options are not effective ways to identify potential attacker activities without affecting production servers:

Video surveillance: This is a physical security technique that uses cameras and monitors to record and observe the activities in a certain area. Video surveillance can help to deter, detect, and investigate physical intrusions, but it does not directly identify the attacker’s activities on the network or the servers3.

Zero Trust: This is a security strategy that assumes that no user, device, or network is trustworthy by default and requires strict verification and validation for every request and transaction. Zero Trust can help to improve the security posture and reduce the attack surface of an organization, but it does not directly identify the attacker’s activities on the network or the servers4.

Geofencing: This is a security technique that uses geographic location as a criterion to restrict or allow access to data or resources. Geofencing can help to protect the data sovereignty andcompliance of an organization, but it does not directly identify the attacker’s activities on the network or the servers5.

Endpoint management software is a tool that allows security engineers to monitor and control the configuration, security, and performance of workstations and servers from a central console. Endpoint management software can help detect and prevent unauthorized changes and software installations, enforce policies and compliance, and provide reports and alerts on the status of the endpoints. The other options are not as effective or comprehensive as endpoint management software for this purpose. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 137 1

Orchestration is the process of automating multiple tasks across different systems and applications. It can help save time and reduce human error by executing predefined workflows and scripts. In this case, the systems administrator can use orchestration to create accounts for a large number of end users without having to manually enter their information and assign permissions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 457 1

Infrastructure as Code (IaC) enables organizations to automate the provisioning, configuration, and deployment of servers through machine-readable scripts rather than manual processes. SY0-701 emphasizes IaC as a key component of DevOps and secure deployment pipelines. By using IaC, server builds become repeatable, standardized, version-controlled, and much faster.

This directly addresses the company ' s goals:

Better control: IaC ensures predictable, consistent configuration across all servers.

Standardization: Scripts eliminate drift by applying identical configurations.

Lower build time: Automation significantly accelerates server creation and eliminates manual intervention.

IoT (A) refers to Internet-connected smart devices and is unrelated to server deployment. PaaS (C) offers development platforms but does not automate infrastructure builds. ICS (D) refers to industrial control systems, not IT server architecture.

Therefore, the only correct architecture that meets all objectives is IaC, a foundational technology for modern automated infrastructure.
