To convert from the cash basis cash payments) to the accrual basis cost of goods sold), an accounts payable must be added to cash payments for goods to determine net purchases.
Net purchases is then adjusted for the change in inventory to determine cost of goods sold.

Two-level (or multi-factor) authentication (MFA) is the most efficient and effective security control for authenticating customers when accessing online shopping accounts. It provides an extra layer of security beyond just passwords, making it more difficult for unauthorized users to gain access.
Stronger Authentication - It requires two independent verification methods, such as:
Something you know (password, PIN)
Something you have (one-time code, mobile device, smart card)
Something you are (biometric feature)
Reduces Risk of Credential Theft - Even if hackers obtain a user ' s password, they still need the second factor to gain access.
Meets Regulatory Standards - Many cybersecurity frameworks (NIST, ISO 27001, PCI-DSS) recommend or mandate MFA for customer authentication.
Enhanced Customer Trust - Provides users with better security, reducing risks of fraud or account takeovers.
A). 12-digit password feature - Longer passwords improve security, but they can still be compromised through phishing or brute force attacks.
B). Security question feature - These are often weak because users choose predictable answers (e.g., mother ' s maiden name).
C). Voice recognition feature - Biometric authentication is useful, but voice recognition can be bypassed using deepfake or recorded audio.
IIA's GTAG (Global Technology Audit Guide) on Information Security Management - Recommends multi- factor authentication for access control.
IIA's International Professional Practices Framework (IPPF) - Standard 2110.A2 - Highlights the need for strong security controls to protect customer data.
NIST SP 800-63 (Digital Identity Guidelines) - Encourages multi-factor authentication as a best practice for securing user accounts.
Why Two-Level Sign-On (MFA) Is the Best Choice?Why Not the Other Options?IIA References:# Final The answer: D. Two-level sign-on feature (Most effective for online customer authentication).

A Wide Area Network (WAN) is the most suitable type of network for an organization that has operations in multiple cities and countries. WANs connect multiple local area networks (LANs) and other types of networks across long geographical distances, enabling seamless communication and data sharing among remote offices and branches.
* A. Wide Area Network (WAN) (Correct Answer)
* WANs cover extensive geographical areas, such as multiple cities, countries, or even continents.
* They use various communication technologies, including leased lines, satellite connections, VPNs, and MPLS.
* WANs enable organizations with distributed operations to centralize data management and enhance business continuity.
* Example: An international corporation like a multinational bank or a global retail chain relies on a WAN to link its offices worldwide.
* B. Local Area Network (LAN) (Incorrect Answer)
* LANs are confined to a small area, such as an office building, factory, or campus.
* They provide high-speed connectivity but are not designed for geographically dispersed locations.
* Example: A single office using Ethernet and Wi-Fi to connect employees' devices.
* C. Metropolitan Area Network (MAN) (Incorrect Answer)
* MANs span a city or a large campus but do not extend to multiple countries.
* Example: A city's government agencies using a fiber-optic MAN for interdepartmental communication.
* D. Storage Area Network (SAN) (Incorrect Answer)
* SANs are dedicated high-speed networks designed for large-scale data storage and retrieval.
* They are not meant for interconnecting geographically dispersed locations.
* Example: A financial institution using a SAN for high-speed access to critical databases.
* The IIA's Global Technology Audit Guide (GTAG) - IT Risks and Controls emphasizes the importance of network infrastructure in securing and managing organizational data across multiple locations.
* IIA Standard 2110 - Governance requires internal auditors to evaluate whether the organization's IT strategy (including WAN infrastructure) supports business objectives and risk management.
* IIA GTAG 17 - Auditing Network Security highlights the importance of WAN security, VPNs, and encryption when managing international operations.
Explanation of Answer Choices:IIA References:Thus, the correct answer is A. Wide Area Network (WAN).

A cold site backup facility is a shell facility where the user can quickly install computer equipment and resume operations in the event of a disaster. The facility has all of the needed assets in place except the needed computer equipment and is vendor-dependent for timely delivery of equipment. Accordingly, an advantage of using a third-party cold site is the elimination of the need for additional equipment. An automobile and personal property insurer has decentralized its information processing to the extent that headquarters has less processing capacity than any of its regional processing centers.
These centers are responsible for initiating policies, communicating with policyholders, and adjusting claims. The company uses leased lines from a national telecommunications company. Initially, the company thought there would be little need for interregion communication, but that has not been the case. The company underestimated the number of customers that would move between regions and the number of customers with claims arising from accidents outside their regions. The company has a regional center in an earthquake-prone area and is planning how to continue processing if that center, or any other single center, were unable to perform its processing.
