IIA Updated IIA-CIA-Part3 Exam Questions and Answers by matthias

The acid-test, or quick ratio, measures immediate liquidity by comparing the most liquid current assets to current liabilities. It usually excludes inventory and other less liquid current assets because they may not be quickly converted into cash. This makes it a stricter liquidity measure than the current ratio. The current ratio measures general short-term solvency, but it includes inventory and prepaid items. Profit margin measures profitability, not liquidity. Times interest earned measures the ability to cover interest expense from earnings, which is more closely related to solvency and debt service capacity. Internal auditors reviewing liquidity should consider quick ratio, cash flow, receivable quality, working capital, and cash conversion cycle. Therefore, Option A is correct.

A spear phishing attack is a targeted email attack aimed at a specific individual, organization, or business. Unlike general phishing, which casts a wide net, spear phishing is highly personalized and designed to deceive the recipient into providing sensitive information.

Personalization – The email references a golf membership renewal, making it relevant and believable to the recipient.

Social Engineering – The attacker exploits the victim’s trust by pretending to be a legitimate entity.

Malicious Link – The victim clicks a fraudulent hyperlink and enters sensitive credit card details.

Financial Fraud – The goal is to steal payment information, leading to unauthorized transactions.

A. Numerous and consistent attacks on the company’s website caused the server to crash.

This describes a Denial-of-Service (DoS) attack, not spear phishing.

B. A person posing as an IT help desk representative called employees and played a generic message requesting passwords.

This describes vishing (voice phishing) rather than spear phishing.

D. Many users of a social network service received fake notifications about a new investment opportunity.

This is general phishing, as it targets multiple users instead of one individual.

IIA’s GTAG (Global Technology Audit Guide) on Cybersecurity – Emphasizes the risk of spear phishing in cyber fraud.

NIST SP 800-61 (Computer Security Incident Handling Guide) – Defines spear phishing as a highly targeted attack method.

COBIT 2019 (Governance and Management of IT) – Highlights social engineering risks in IT security.

Why Option C is Correct?Why Not the Other Options?IIA References:✅ Final Answer: C. A person received a personalized email regarding a golf membership renewal, and he clicked a hyperlink to enter his credit card data into a fake website.

The auditor ' s observation indicates that backup media is stored on-site in the data center, which is a major risk in disaster recovery and business continuity planning (BCP). Best practices recommend storing backup media off-site to prevent data loss due to fires, floods, cyberattacks, or other disasters affecting the primary site.

Off-Site Storage Reduces Disaster Risks:

Keeping backups only at the primary data center means that any physical disaster (fire, flood, theft, or power surge) can destroy both primary and backup data.

Best practices require off-site or cloud-based backup storage to ensure data recovery in case of emergencies.

Regulatory and Compliance Considerations:

IIA Standard 2110 (Governance): Emphasizes disaster recovery policies to protect critical IT assets.

ISO/IEC 27001 (Information Security Management System): Recommends storing backups in a geographically separate location.

NIST SP 800-34 (Contingency Planning Guide for Federal Information Systems): Requires off-site storage to ensure effective disaster recovery.

Why the Other Options Are Incorrect:

B. Backup procedures are adequate and appropriate according to best practices: ❌

Incorrect, as on-site-only storage violates best practices for disaster recovery.

C. Backup media is not properly indexed, as backup media should be indexed by system, not date: ❌

While indexing is important, the main issue here is improper storage, not indexing methods.

D. Backup schedule is not sufficient, as full backup should be conducted daily: ❌

Backup frequency depends on business needs; a weekly backup is common for many organizations.

However, the biggest concern here is lack of off-site storage, not frequency.

IIA GTAG (Global Technology Audit Guide) on Business Continuity and Disaster Recovery: Recommends off-site storage for backups.

ISO/IEC 27001 – Information Security Controls (A.12.3.1): Requires backup data to be securely stored off-site.

COBIT 5 Framework – DSS04 (Manage Continuity): Supports off-site backups for IT continuity.

Step-by-Step Justification:IIA References:Thus, the correct answer is A. Backup media is not properly stored, as the storage facility should be off-site. ✅

The arrangement described is a cold recovery plan because the organization has an agreement to obtain equipment and restore data from off-site tapes, but the recovery site is not already fully configured and operational. A hot site would have systems, infrastructure, and data ready for rapid failover, often with real-time or near-real-time synchronization. A warm site would typically have some configured hardware and infrastructure already available, although not fully current. “No recovery plan” is incorrect because management has at least arranged for equipment rental and off-site backup restoration. Internal auditors should evaluate whether the selected recovery approach meets recovery time objectives, recovery point objectives, and business impact analysis requirements. Therefore, Option C is correct.
