Representative Practice Questions for IBPS SO XVI 2026

Working through authentic practice questions with detailed step-by-step technical explanations clarifies exam expectations and reinforces core technical principles across specialized domains.

1. IT Officer Scale I Worked Problems

Question 1 (Computer Networks - Subnetting): An organization is assigned the network block 192.168.10.0/24. The network administrator needs to create 4 equal-sized subnets. What is the new subnet mask and the maximum number of usable host addresses in each subnet?

Step-by-Step Solution:

To create 4 subnets ($2^2 = 4$), we must borrow 2 bits from the host portion.
Original prefix = $/24$. New prefix = $24 + 2 = /26$.
New subnet mask in binary: 11111111.11111111.11111111.11000000 = 255.255.255.192.
Host bits remaining = $32 - 26 = 6 ext{ bits}$.
Total addresses per subnet = $2^6 = 64$.
Usable host addresses = $2^6 - 2 = 64 - 2 = mathbf{62 ext{ hosts}}$.

Answer: Subnet Mask: 255.255.255.192 | Usable Hosts: 62.

Question 2 (DBMS - Transactions): Which ACID property ensures that all operations within a database transaction are completed successfully, or if any operation fails, the entire transaction is rolled back to leave the database unchanged?

Explanation: The Atomicity property ('all-or-nothing') guarantees that a multi-step transaction is treated as a single atomic unit of work. If a system failure occurs midway, the transaction aborts and all partial changes are rolled back to the initial state.

Answer: Atomicity.

Question 3 (Agronomy): What is the recommended seed rate for direct-seeded upland rice versus transplanted puddle rice per hectare?

Explanation: In conventional transplanted puddle rice, the recommended seed rate is roughly 40 to 50 kg/ha. For direct-seeded rice (DSR) or broadcasting, the seed rate increases to 80 to 100 kg/ha to compensate for lower germination rates and early weed competition. In System of Rice Intensification (SRI), the seed rate drops to just 5 to 7 kg/ha.

Answer: Transplanted: 40-50 kg/ha | Direct Seeded: 80-100 kg/ha.

3. Marketing Officer Scale I Worked Problem

Question 4 (Marketing Management): In the Boston Consulting Group (BCG) Growth-Share Matrix, a business unit operating in a low-growth market but commanding a dominant high market share is classified as a:

Explanation: In the BCG Matrix, business units with high market share in a mature, low-growth industry are categorized as Cash Cows. They generate large, steady cash flows that exceed the investment needed to maintain them, which is used to fund 'Stars' or 'Question Marks'.

Answer: Cash Cow.

Frequently Asked Questions

How do you calculate the usable host IP addresses in a CIDR subnet block?

In any IPv4 subnet with a prefix length $/n$, the total number of IP addresses is $2^{(32 - n)}$. The number of usable host addresses is always $2^{(32 - n)} - 2$, subtracting 2 for the Network ID (first address) and the Directed Broadcast Address (last address). For example, a $/27$ subnet provides $2^{(32-27)} - 2 = 2^5 - 2 = 30$ usable host IPs.

What is the difference between 3NF and BCNF normalization in relational databases?

A relation is in 3NF if for every functional dependency $X o Y$, either $X$ is a superkey or $Y$ is a prime attribute (part of a candidate key). Boyce-Codd Normal Form (BCNF) is stricter: for every functional dependency $X o Y$, $X$ MUST be a superkey. BCNF eliminates anomalies where an attribute depends on a non-superkey.

What is the seed rate and isolation distance concept in Agricultural Field Officer questions?

Seed rate is the quantity of seed required for planting one unit area (e.g., kg/hectare) to establish an optimal plant population. Isolation distance is the minimum physical separation maintained between seed production fields and neighboring fields of the same crop to prevent unwanted genetic cross-pollination during certified seed production.
