To prevent all hardware failures<\/span><\/p>\nAnswer: 2) To verify that data can be successfully restored when needed<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Backup procedures are only effective if the organization can recover usable data when required. Regular restoration testing verifies that backup files are complete, accessible, and capable of supporting recovery objectives. It can also identify problems such as corrupted backup media, incorrect configurations, missing files, or inadequate recovery procedures. An IS auditor should determine whether backup testing is performed according to organizational requirements and whether test results are documented and reviewed. Simply confirming that backups were created does not prove that they can be restored successfully. Restoration testing therefore provides assurance that the organization has a practical capability to recover critical information after a disruption or data-loss event.<\/span><\/p>\nQuestion 102. Which activity provides the strongest evidence that a backup recovery procedure is effective?<\/b><\/h3>\n
1)<\/b> Reviewing the backup schedule<\/span>
\n<\/span>2)<\/b> Checking that backup jobs show successful status messages<\/span>
\n<\/span>3)<\/b> Confirming that backup storage has sufficient capacity<\/span>
\n<\/span>4)<\/b> Performing a documented restoration test using selected backup data<\/span><\/p>\nAnswer: 4) Performing a documented restoration test using selected backup data<\/b><\/p>\n
Explanation:<\/b><\/p>\n
A documented restoration test provides direct evidence that backup data can actually be recovered and used. Successful backup job messages only indicate that the backup process completed according to the system, but they do not necessarily prove that the resulting data is complete or restorable. A restoration test allows the organization to identify corrupted files, incomplete backups, configuration problems, or procedural weaknesses before a real recovery is required. The IS auditor should review test scope, results, exceptions, and management follow-up. Testing should cover appropriate systems and data based on business criticality and recovery requirements. This provides stronger assurance than simply reviewing backup logs or schedules.<\/span><\/p>\nQuestion 103. Which backup control is specifically designed to reduce the risk of ransomware encrypting available backup copies?<\/b><\/h3>\n
1)<\/b> Maintaining immutable or offline backup copies<\/span>
\n<\/span>2)<\/b> Increasing the frequency of user password changes<\/span>
\n<\/span>3)<\/b> Disabling system monitoring during backups<\/span>
\n<\/span>4)<\/b> Storing all backups on the same production network<\/span><\/p>\nAnswer: 1) Maintaining immutable or offline backup copies<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Immutable or offline backups provide additional protection because attackers cannot easily modify or encrypt them through compromised production systems. Immutable storage prevents changes or deletion for a defined retention period, while offline backups are isolated from normal network access. These approaches can support recovery when production data and connected backup repositories have been compromised. An IS auditor should evaluate whether backup protections are aligned with the organization\u2019s recovery requirements and threat environment. The auditor should also verify that protected copies are tested periodically. Maintaining multiple protected recovery copies can improve resilience, but organizations should still confirm that the backup data is usable through appropriate restoration testing.<\/span><\/p>\nQuestion 104. Which control is most important for ensuring that database transactions are processed completely and accurately?<\/b><\/h3>\n
1)<\/b> Increasing database storage capacity<\/span>
\n<\/span>2)<\/b> Allowing all users direct database access<\/span>
\n<\/span>3)<\/b> Using input, processing, and output controls with appropriate transaction validation<\/span>
\n<\/span>4)<\/b> Removing database audit records after processing<\/span><\/p>\nAnswer: 3) Using input, processing, and output controls with appropriate transaction validation<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Database transaction integrity depends on controls throughout the processing cycle. Input controls help ensure that only valid and authorized data enters the system. Processing controls help verify that calculations and transactions are performed completely and accurately, while output controls help ensure that generated information is accurate and distributed appropriately. Depending on the system, additional controls may include transaction sequencing, completeness checks, validation rules, error handling, and reconciliation. An IS auditor should evaluate whether these controls are appropriately designed and operating effectively. Increasing storage capacity does not directly ensure transaction integrity, and unrestricted access or deletion of audit records can introduce significant control weaknesses.<\/span><\/p>\nQuestion 105. Which database control helps ensure that a record cannot reference a nonexistent related record?<\/b><\/h3>\n
1)<\/b> Encryption<\/span>
\n<\/span>2)<\/b> Referential integrity<\/span>
\n<\/span>3)<\/b> Data compression<\/span>
\n<\/span>4)<\/b> Load balancing<\/span><\/p>\nAnswer: 2) Referential integrity<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Referential integrity is a database control that helps maintain valid relationships between related tables. It ensures that a foreign key value corresponds to an appropriate primary key or otherwise permitted relationship in the referenced table. For example, an order should not reference a customer record that does not exist. Maintaining referential integrity reduces inconsistent, orphaned, or invalid relationships within databases. An IS auditor reviewing database controls should consider whether integrity constraints are appropriately designed and enforced. Encryption protects confidentiality, compression reduces storage requirements, and load balancing distributes processing workloads. None of these controls directly addresses the validity of relationships between related database records.<\/span><\/p>\nQuestion 106. What is the primary purpose of data masking when sensitive information is used in a nonproduction environment?<\/b><\/h3>\n
1)<\/b> To permanently delete the original production data<\/span>
\n<\/span>2)<\/b> To increase database processing speed<\/span>
\n<\/span>3)<\/b> To remove the need for access controls<\/span>
\n<\/span>4)<\/b> To obscure sensitive values while retaining usable data characteristics**<\/span><\/p>\nAnswer: 4) To obscure sensitive values while retaining usable data characteristics<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Data masking protects sensitive information by replacing or obscuring actual values while preserving enough structure or characteristics for authorized testing or development activities. For example, a test environment may require realistic customer records but should not expose actual personal or financial information unnecessarily. Masking can reduce the risk of sensitive data exposure when production information is copied outside controlled production environments. An IS auditor should evaluate whether masking rules adequately protect sensitive fields and whether masked datasets remain suitable for their intended purpose. Data masking does not eliminate the need for access controls, encryption, or other security measures. It is one layer within a broader data protection strategy.<\/span><\/p>\nQuestion 107. Which control should be based primarily on an organization’s information classification scheme?<\/b><\/h3>\n
1)<\/b> Handling and protection requirements for different types of information<\/span>
\n<\/span>2)<\/b> The physical location of every employee<\/span>
\n<\/span>3)<\/b> The number of software developers assigned to a project<\/span>
\n<\/span>4)<\/b> The color used in application interfaces<\/span><\/p>\nAnswer: 1) Handling and protection requirements for different types of information<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Information classification identifies the sensitivity and importance of information and provides a basis for determining appropriate handling requirements. Highly sensitive information may require stronger access restrictions, encryption, retention controls, secure transmission, and specialized disposal procedures than publicly available information. An IS auditor should assess whether classification categories are clearly defined, consistently applied, and supported by appropriate handling procedures. Classification should also be understood by employees and other authorized users who handle organizational information. The purpose is to align protection measures with information sensitivity and business requirements. Classification should not be based on irrelevant factors such as interface design, employee location, or development team size.<\/span><\/p>\nQuestion 108. What is the primary purpose of a privacy impact assessment (PIA)?<\/b><\/h3>\n
1)<\/b> To determine the financial value of a database<\/span>
\n<\/span>2)<\/b> To measure application processing speed<\/span>
\n<\/span>3)<\/b> To identify and evaluate privacy risks associated with processing personal information<\/span>
\n<\/span>4)<\/b> To replace all information security assessments<\/span><\/p>\nAnswer: 3) To identify and evaluate privacy risks associated with processing personal information<\/b><\/p>\n
Explanation:<\/b><\/p>\n
A privacy impact assessment helps an organization identify and evaluate potential privacy risks associated with collecting, using, storing, sharing, or otherwise processing personal information. It can be performed during planning or before significant changes to systems and processes so that privacy considerations can be addressed early. An effective PIA may examine the types of personal information involved, purposes of processing, access, retention, disclosure, and applicable obligations. An IS auditor may review whether PIAs are required by organizational policy or applicable regulations and whether identified risks receive appropriate treatment. A PIA complements security assessments rather than replacing broader security or risk-management activities.<\/span><\/p>\nQuestion 109. Which principle recommends collecting only the personal information necessary for a specified business purpose?<\/b><\/h3>\n
1)<\/b> Data replication<\/span>
\n<\/span>2)<\/b> Data minimization<\/span>
\n<\/span>3)<\/b> Data aggregation<\/span>
\n<\/span>4)<\/b> Data redundancy<\/span><\/p>\nAnswer: 2) Data minimization<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Data minimization means limiting the collection and processing of personal information to what is necessary for a defined and legitimate purpose. Collecting unnecessary information can increase privacy exposure, storage requirements, access-control requirements, and the potential impact of a security incident. An IS auditor should assess whether business processes define the information they genuinely require and whether unnecessary fields are avoided. Data minimization can also support retention management by reducing the amount of information that must be maintained. It does not mean that organizations should eliminate information needed for legitimate business operations. Instead, it encourages purposeful collection and processing consistent with documented requirements and applicable obligations.<\/span><\/p>\nQuestion 110. What is the primary objective of third-party risk management?<\/b><\/h3>\n
1)<\/b> To transfer all organizational risks to vendors<\/span>
\n<\/span>2)<\/b> To eliminate the need for internal controls<\/span>
\n<\/span>3)<\/b> To ensure vendors use identical technology to the organization<\/span>
\n<\/span>4)<\/b> To identify, assess, and manage risks arising from third-party relationships**<\/span><\/p>\nAnswer: 4) To identify, assess, and manage risks arising from third-party relationships<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Third-party risk management helps an organization understand and control risks associated with vendors, suppliers, contractors, and other external service providers. These risks may involve information security, privacy, availability, compliance, business continuity, and operational dependencies. Effective management typically includes due diligence before engagement, contractual requirements, ongoing monitoring, performance reviews, and appropriate exit arrangements. An IS auditor should assess whether third-party risks are identified according to business importance and whether controls are proportionate to the services and information involved. Outsourcing a function does not automatically transfer accountability for managing associated risks. The organization should maintain appropriate oversight of critical external relationships throughout their lifecycle.<\/span><\/p>\nQuestion 111. Which activity should normally occur before an organization enters into a contract with a critical service provider?<\/b><\/h3>\n
1)<\/b> Performing appropriate vendor due diligence<\/span>
\n<\/span>2)<\/b> Removing all contractual security requirements<\/span>
\n<\/span>3)<\/b> Granting unrestricted system access immediately<\/span>
\n<\/span>4)<\/b> Waiting until the contract expires to assess risk<\/span><\/p>\nAnswer: 1) Performing appropriate vendor due diligence<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Vendor due diligence helps an organization evaluate whether a prospective service provider has the capabilities, controls, financial stability, security practices, and operational arrangements necessary to support the relationship. For critical providers, due diligence may include reviewing independent assurance reports, security documentation, business continuity capabilities, relevant certifications, control assessments, and references. The depth of assessment should be proportionate to the services provided and associated risks. An IS auditor should verify that due diligence occurs before material commitments are made and that significant findings are addressed. Contractual requirements should then reflect the identified risks and the organization’s expectations for security, performance, compliance, and continuity.<\/span><\/p>\nQuestion 112. Which item should be included in an SLA when information security is a significant concern?<\/b><\/h3>\n
1)<\/b> Employee vacation schedules<\/span>
\n<\/span>2)<\/b> Office decoration standards<\/span>
\n<\/span>3)<\/b> Clearly defined security responsibilities and measurable security requirements<\/span>
\n<\/span>4)<\/b> Personal preferences of individual administrators<\/span><\/p>\nAnswer: 3) Clearly defined security responsibilities and measurable security requirements<\/b><\/p>\n
Explanation:<\/b><\/p>\n
A service-level agreement should establish clear and measurable expectations when security is an important aspect of an outsourced service. Relevant requirements may address access management, incident notification, availability, vulnerability management, data protection, logging, compliance, and response times. Clearly assigned responsibilities help prevent gaps between the organization and the service provider. Measurable requirements also allow performance to be monitored and exceptions to be identified. An IS auditor should determine whether security obligations are documented, understood, and monitored throughout the contract period. Generic statements that a provider will maintain security may not provide sufficient assurance because they may lack measurable requirements, responsibilities, or consequences for noncompliance.<\/span><\/p>\nQuestion 113. What is the primary purpose of a right-to-audit clause in a third-party contract?<\/b><\/h3>\n
1)<\/b> To allow the vendor to change organizational policies<\/span>
\n<\/span>2)<\/b> To provide the organization with defined rights to assess the provider’s relevant controls<\/span>
\n<\/span>3)<\/b> To eliminate the need for service-level agreements<\/span>
\n<\/span>4)<\/b> To guarantee that no audit findings will occur<\/span><\/p>\nAnswer: 2) To provide the organization with defined rights to assess the provider’s relevant controls<\/b><\/p>\n
Explanation:<\/b><\/p>\n
A right-to-audit clause establishes contractual authority for an organization to obtain information or perform assessments concerning a service provider’s relevant controls. Depending on the agreement, this may involve reviewing independent assurance reports, conducting assessments, requesting evidence, or performing other agreed procedures. Such provisions are particularly important when a provider handles sensitive information or supports critical business processes. An IS auditor should determine whether contractual audit rights are practical, clearly defined, and consistent with the organization’s risk requirements. The clause does not guarantee that controls are effective; rather, it provides a mechanism through which the organization can obtain assurance and investigate significant concerns.<\/span><\/p>\nQuestion 114. What is a key benefit of reviewing an independent SOC report for a critical service provider?<\/b><\/h3>\n
1)<\/b> It guarantees that the provider has no security weaknesses<\/span>
\n<\/span>2)<\/b> It replaces every internal audit procedure<\/span>
\n<\/span>3)<\/b> It eliminates the need for contractual requirements<\/span>
\n<\/span>4)<\/b> It provides independent information about specified controls and their operation**<\/span><\/p>\nAnswer: 4) It provides independent information about specified controls and their operation<\/b><\/p>\n
Explanation:<\/b><\/p>\n
A SOC report can provide useful independent assurance information about controls operated by a service organization. Depending on the report type and scope, it may describe relevant controls and provide information about whether those controls were suitably designed and, in applicable reports, operated effectively over a defined period. An IS auditor should review the report’s scope, period, service commitments, control objectives, exceptions, and the relevance of the covered services to the organization. A SOC report does not automatically guarantee that every risk is addressed because its scope is limited. Organizations should therefore determine whether additional procedures or evidence are necessary based on their own risk assessment.<\/span><\/p>\nQuestion 115. Under the cloud shared responsibility model, which statement is generally correct?<\/b><\/h3>\n
1)<\/b> Security responsibilities are divided between the cloud provider and the customer according to the services used<\/span>
\n<\/span>2)<\/b> The cloud provider is always responsible for every customer configuration<\/span>
\n<\/span>3)<\/b> The customer has no responsibility for access management<\/span>
\n<\/span>4)<\/b> The customer is always responsible for physical data-center security<\/span><\/p>\nAnswer: 1) Security responsibilities are divided between the cloud provider and the customer according to the services used<\/b><\/p>\n
Explanation:<\/b><\/p>\n
The shared responsibility model recognizes that cloud security responsibilities are distributed between the provider and customer, although the exact division depends on the cloud service model and provider arrangement. Providers generally manage certain underlying infrastructure responsibilities, while customers may remain responsible for areas such as identities, data, configurations, applications, or operating systems depending on the service. An IS auditor should understand the specific responsibilities documented in the cloud agreement and service model rather than assuming that the provider handles all security activities. Effective auditing therefore requires reviewing contractual responsibilities, configurations, monitoring arrangements, and evidence that both parties are performing their assigned controls.<\/span><\/p>\nQuestion 116. When auditing a cloud environment, what should the auditor first establish regarding security configuration responsibilities?<\/b><\/h3>\n
1)<\/b> That all cloud configurations are controlled exclusively by the provider<\/span>
\n<\/span>2)<\/b> That configuration management is unnecessary in cloud services<\/span>
\n<\/span>3)<\/b> Which security configuration responsibilities belong to the customer and which belong to the provider<\/span>
\n<\/span>4)<\/b> That customers should avoid documenting cloud configurations<\/span><\/p>\nAnswer: 3) Which security configuration responsibilities belong to the customer and which belong to the provider<\/b><\/p>\n
Explanation:<\/b><\/p>\n
Cloud environments can involve different security responsibilities depending on the service model and contractual arrangement. Before evaluating configuration controls, an auditor should establish which party is responsible for specific settings and activities. Customer responsibilities may include identity permissions, network settings, application configurations, encryption options, or other controls depending on the service. Provider responsibilities may involve underlying infrastructure and platform components. Clearly understanding this division prevents an auditor from assigning responsibility to the wrong party. The auditor should then evaluate whether each party performs its assigned activities and whether evidence exists to demonstrate effective configuration management, monitoring, and review.<\/span><\/p>\nQuestion 117. Which control is most important for protecting an API from unauthorized requests?<\/b><\/h3>\n
1)<\/b> Increasing screen resolution<\/span>
\n<\/span>2)<\/b> Strong authentication and authorization controls<\/span>
\n<\/span>3)<\/b> Disabling all application logging<\/span>
\n<\/span>4)<\/b> Increasing database storage capacity<\/span><\/p>\nAnswer: 2) Strong authentication and authorization controls<\/b><\/p>\n
Explanation:<\/b><\/p>\n
APIs expose application functionality and data through programmatic interfaces, making authentication and authorization important security controls. Authentication helps establish the identity of the requester, while authorization determines which resources or operations that requester is permitted to access. Additional API controls can include rate limiting, input validation, secure transport, logging, monitoring, and protection against common application attacks. An IS auditor should evaluate whether API access is appropriately restricted and whether permissions follow business requirements and least-privilege principles. Strong controls should also account for service-to-service communication and credential management where applicable. Merely increasing storage capacity or disabling logging does not protect an API from unauthorized requests.<\/span><\/p>\nQuestion 118. What is a primary objective of secure code review?<\/b><\/h3>\n
1)<\/b> To increase the number of application features<\/span>
\n<\/span>2)<\/b> To eliminate all testing requirements<\/span>
\n<\/span>3)<\/b> To reduce software documentation<\/span>
\n<\/span>4)<\/b> To identify security weaknesses in source code before deployment**<\/span><\/p>\n
