CompTIA Updated CS0-003 Exam Questions and Answers by juliet

The given firewall logs indicatehigh outbound traffic with low IP reputation, sustained over time, which is a strongindicator of cryptomining activity​.

Option A (Anomalous activity)is a general term but does not specifywhythe activity is suspicious.

Option B (Bandwidth saturation)occurs when network traffic is overwhelming, but cryptomining typicallyuses CPU/GPU powerrather than overwhelming bandwidth.

Option D (Denial of service - DoS)would result incontinuous large requests, but cryptomining generatesconsistent, high-bandwidth outbound trafficrather than bursts of large requests.

Thus,C is the correct answer, as cryptomininggenerates unusual outbound network activity from internal hosts to mining pools​.

The correct answer is C. False negative.

A false negative is a situation where an attack or a threat is not detected by a security control, even though it should have been. In this case, the SIEM rule was unable to detect an attack with nine failed logins, which is below the threshold of ten failed logins that triggers an alert. This means that the SIEM rule missed a potential attack and failed to alert the security analysts, resulting in a false negative.

A false positive is a situation where a benign or normal activity is detected as an attack or a threat by a security control, even though it is not. A true negative is a situation where a benign or normal activity is not detected as an attack or a threat by a security control, as expected. A true positive is a situation where an attack or a threat is detected by a security control, as expected. These are not the correct answers for this question.

Security Orchestration, Automation, and Response (SOAR)solutions allow organizations tointegrate security tools, automate response actions, and aggregate threat intelligence. This matches the organization ' s goal ofthreat detection, real-time analysis, and data aggregation​.

Option A (DLP - Data Loss Prevention)is focused ondata securityrather than threat aggregation and response automation.

Option B (Heuristics)is amethod for threat detection, not aplatformfor security automation.

Option D (NAC - Network Access Control)manages device access rather than handling security automation.

Thus,C (SOAR) is the correct answer, asit automates threat detection, intelligence integration, and real-time response​.

Comprehensive Detailed Explanation:A Service Level Agreement (SLA) defines the expectations, requirements, and metrics for third-party services, including response times and responsibilities during an event. Here’s an overview of each option:

A. BIA (Business Impact Analysis)

Explanation: BIA is used to assess potential impacts of disruptions to business operations, but it does not specify third-party response requirements.

B. DRP (Disaster Recovery Plan)

Explanation: DRP provides recovery procedures for internal systems and services but does not directly establish third-party obligations.

C. SLA (Service Level Agreement)

Explanation: SLAs set clear expectations for third-party services, including response times, performance metrics, and specific requirements during incidents. SLAs ensure accountability for external providers during critical events.

D. MOU (Memorandum of Understanding)

Explanation: An MOU defines general terms and intentions between parties but lacks the specific performance metrics required in an SLA.
