Treating 'IT governance' as a synonym for 'IT management' and answering that the CIO or IT steering committee 'owns' IT risk decisions, instead of selecting the board-level accountability option.
Candidates read governance questions through a technical lens because the rest of the exam is technical; the distinction between direction-and-oversight (board) and execution (management) is not intuitive to engineers. Option lists often place the CIO as a tempting distractor.
What to do instead
Memorise the governance chain: shareholders → board → board IT/risk committee → executive management → IT function. For any question containing 'accountable', 'ultimate responsibility', 'direction', or 'oversight', the answer sits with the board or a board committee, never the CIO, CISO or IT manager. Practise by labelling each option as 'set direction', 'provide assurance' or 'execute'.
Choosing the 'strongest' control (e.g. biometric authentication, full disk encryption, SIEM) when the question asks for the most appropriate or cost-effective control for a given risk, and ignoring the layered or preventive/detective/corrective classification the scenario implies.
Security-trained candidates equate 'more secure' with 'more correct'. Exam items are usually testing control selection by risk profile, data classification and proportionality, not raw strength, so the strongest option is frequently the over-engineered wrong answer.
What to do instead
For every control question, first classify the control type (preventive, detective, corrective, deterrent, compensating) and the asset sensitivity, then eliminate options that are disproportionate to the stated classification or risk. Where two options are both strong, prefer the one that fits the layer the scenario says is missing.
Confusing IT audit's role with IT operations or security operations: answering that the auditor implements remediation, approves firewall changes, or 'ensures' compliance, rather than providing independent assurance and reporting to the audit committee.
Many candidates come from operations or security backgrounds where the same team does both, and the independence principle is treated as a formality rather than the defining feature of audit. Wording like 'ensure' versus 'provide assurance' is easy to skim past.
What to do instead
Anchor on independence: audit never designs, implements or owns controls; it evaluates and reports. Reject any option where the auditor 'ensures', 'implements', 'approves' or 'owns'. Check the reporting line - functional reporting to the audit committee, administrative reporting to the CEO - and treat 'reports to the CIO' as automatically wrong.
Misreading RTO, RPO, MTD and RTO-versus-recovery-time in business continuity items, for example selecting the RPO as the acceptable downtime or treating the BIA as an IT task rather than a business-owned exercise.
The acronyms look interchangeable and are often tested inside a numeric scenario. Candidates under time pressure grab the first familiar term rather than mapping each to data loss versus downtime versus maximum tolerable disruption.
What to do instead
Build a one-line glossary and apply it mechanically: RTO = maximum acceptable time to restore the service; RPO = maximum acceptable data loss measured in time; MTD/MTPD = the point of intolerable harm; BIA = business-owned determination of criticality and dependencies. When a question states 'four hours of transactions may be lost', that is RPO; 'systems back within eight hours' is RTO.
Answering outsourcing and vendor-risk questions by focusing only on contract clauses or SLAs, and missing the retained obligations: due diligence, ongoing monitoring, right-to-audit, subcontractor disclosure, exit/transition planning and the fact that accountability for outsourced processes cannot be transferred.
Candidates treat outsourcing as a procurement/legal topic and pick the option that sounds like good contract drafting, whereas the exam tests the regulated entity's continuing responsibility and supervisory expectations for material outsourced activities.
What to do instead
For every outsourcing item, ask 'what does the regulated entity still owe the regulator and customer?'. Prefer options containing due diligence before signing, documented risk assessment, right to audit and access, subcontractor approval, exit strategy and business continuity testing at the vendor. Eliminate any option implying the vendor assumes the bank's regulatory accountability.
Confusing IT service management process boundaries - logging an incident versus raising a problem record, change management versus release and deployment, service level versus operational level agreements - and picking the process name that sounds closest.
The processes overlap in real life and the distractors are deliberately adjacent. Candidates who have not internalised the purpose of each process default to 'incident' for anything that goes wrong and 'change' for anything that alters a system.
What to do instead
Learn each process by its question: incident = restore service fast; problem = find and remove root cause; change = authorise and control modification with risk assessment and rollback; release/deployment = move tested components into production; SLA = customer-facing target, OLA = internal support agreement. Read the stem for the verb (restore, prevent recurrence, authorise, transfer) and map it to the process.
Treating core banking and delivery-channel questions as product knowledge, so answers describe vendor features instead of the architectural and control concepts - e.g. not recognising that the channel layer should not hold the system of record, or missing the reconciliation and exception controls around ATM/POS/UPI-style switches.
Candidates prepare from vendor brochures and news about specific products, while the exam tests concepts such as CBS modules, straight-through processing, host-to-host integration, channel security and reconciliation. Product familiarity creates false confidence.
What to do instead
Study the functional architecture instead of products: customer master, deposits, loans, payments, GL, reporting; how channels (ATM, POS, internet, mobile, branch) connect through middleware/switch to the CBS; where reconciliation, exception queues, cut-off times and reversal controls sit. For any channel question, ask 'where is the system of record and what control proves the two sides agree?'.
Answering digital-banking and payment-system items with consumer intuition - assuming card-not-present liability rules, chargeback rights, tokenisation scope, two-factor authentication requirements or settlement finality work the same way across channels and schemes.
Everyday experience with banking apps and cards feels authoritative, but the exam tests scheme rules, regulatory mandates on authentication, and the difference between authorisation, clearing and settlement. Intuition about 'who pays when fraud happens' is often wrong.
What to do instead
Separate the payment lifecycle into authorisation, clearing, settlement and dispute, and learn who bears liability at each stage and what the scheme or regulator mandates. For authentication questions, check whether the requirement is for a second factor, dynamic linking to the transaction amount, or exemption rules, and reject options that apply one channel's rule to another.
Over-claiming on emerging technology questions - selecting blockchain/distributed ledger, AI or cloud as the answer for any modernisation scenario, and asserting properties (immutability solving fraud, cloud automatically improving resilience, AI removing the need for model validation) that the scenario does not support.
Hype-driven preparation and news headlines create a bias toward the newest option. Exam items usually test the control and governance implications of the technology, and the correct answer is often a limitation, a risk, or a 'not suitable because' option.
What to do instead
For each emerging technology, prepare a two-column note: what it genuinely changes, and what it does not. Reject options that claim a technology eliminates a control need. Where a scenario mentions distributed ledger, cloud or AI, look for the governance answer - data residency, model validation and explainability, key management, concentration risk, auditability - rather than the capability answer.
Managing time and question stems poorly: answering from the first recognisable keyword without reading qualifiers such as 'BEST', 'PRIMARY', 'FIRST step', 'EXCEPT' or 'not', and leaving no time to revisit flagged scenario questions.
The paper mixes short recall items with long scenario stems, and the familiar term appears early in the option. Under time pressure candidates pattern-match rather than parse, which is where most avoidable marks are lost on an otherwise well-prepared attempt.
What to do instead
Adopt a fixed reading routine: underline the qualifier, identify the domain, restate the requirement in one line before looking at options, then eliminate two options and justify the winner. Flag any item needing more than about 90 seconds and return to it; do not leave scenario items blank where there is no negative marking. Rehearse this on timed mixed-domain sets, not on topic-by-topic drills.
