Question 8

A startup uses a spreadsheet to track monthly revenue. The revenue for the first 3 months is $R_1 = 1200$, $R_2 = 1500$, and $R_3 = 1800$. If the growth follows an arithmetic sequence $R_n = R_1 + (n-1)d$, calculate the projected revenue for month $n = 12$.

Accepted Answer

4500

Question 9

A small business implements a compensating control for a lack of segregation of duties. If the probability of an error occurring is $P(E) = 0.05$ and the probability of a manager detecting it is $P(D|E) = 0.80$, calculate the probability that an error occurs and remains undetected $P(E \cap D^c)$.

Question 10

In an acquisition-based growth strategy, the 'immediate integration' method requires data transformation where the source system format $S_1$ must be mapped to the target system format $S_2$ such that $f: S_1 	o S_2$ is a bijective mapping to ensure data integrity.

Accepted Answer

True

Answer

False

Question 11

Question 14

A manufacturing firm experiences a bottleneck where production schedules are not updated based on real-time inventory depletion. If the firm's total production capacity is $C = 500$ units/day and the current inventory depletion rate is $R = 0.8C$, calculate the required production adjustment $A$ to maintain a buffer of $B = 150$ units when the current stock $S = 50$ units. Which module should be prioritized to automate this calculation?

Accepted Answer

Production Module

Answer

Financial Module

Answer

CRM Module

Answer

HRM Module

Question 15

A company evaluates a SaaS ERP implementation. The upfront cost is $U = €50,000$ and the annual subscription cost is $S = €12,000$. An on-premise solution costs $O = €150,000$ with annual maintenance $M = €3,000$. Calculate the break-even time $t$ in years where $U + St = O + Mt$. Solve for $t$.

Accepted Answer

11.11 years

Question 16

In a distributed system architecture, the total latency $L$ is defined by the sum of processing time $P$ and network transmission time $T$, where $L = P + T$. If a firm transitions from a centralized system ($T_{central} = 50ms$) to a distributed system ($T_{dist} = 10ms$) but increases processing complexity ($P_{dist} = 2P_{central}$), which of the following scenarios would make the distributed system more efficient ($L_{dist} < L_{central}$)?

Answer

When $P_{central} < 40ms$

Answer

When $P_{central} > 40ms$

Answer

When $P_{central} = 50ms$

Answer

When $T_{dist} > T_{central}$

Question 17

In a decentralized system, the total cost of data aggregation $C_a$ is proportional to the number of nodes $n$ such that $C_a = k \cdot n^2$. If $n$ increases from 4 to 8, the cost of aggregation increases by a factor of 4.

Accepted Answer

True

Answer

False

Question 18

A firm uses a centralized ERP system where the probability of system failure is $P_f = 0.05$. If the firm adds a redundant server to create a distributed-like failover, the new probability of failure becomes $P_{new} = P_f^2$. Calculate the new probability of failure.
