Applying the Framework and Exam Preparation
4 questions in this domain
- Question 1Single Choice
What is the very first step in the NIST CSF implementation methodology?
- APrioritize and ScopeCorrect answer
- BCreate a Current Profile
- CConduct a Risk Assessment
- DImplement an Action Plan
Why this is the answer
The methodology begins with Prioritize and Scope, where the organization identifies business objectives and defines the boundaries of the implementation. This step ensures alignment with senior leadership's risk appetite.
- Question 2Multiple Select
Which two steps are part of the NIST CSF seven‑step implementation methodology? (Select two.)
- APrioritize and ScopeCorrect answer
- BOrientCorrect answer
- CCreate a Risk Register
- DConduct a Compliance Audit
Why this is the answer
The methodology consists of seven steps: Prioritize and Scope, Orient, Create a Current Profile, Conduct a Risk Assessment, Create a Target Profile, Determine/Analyze/Prioritize Gaps, and Implement an Action Plan. Creating a risk register and conducting a compliance audit are not standalone steps in the CSF implementation process.
- Question 3Interactive
Read the scenario in the code block below. Then select the Implementation Tier that best describes the organization.
- ATier 1 – PartialCorrect answer
- BTier 2 – Risk Informed
- CTier 3 – Repeatable
- DTier 4 – Adaptive
Why this is the answer
The organization has no formal cybersecurity process and reacts only when an incident occurs. This reactive, ad‑hoc approach matches Tier 1 (Partial).
- Question 4Single Choice
What is the primary purpose of a Current Profile in the NIST CSF?
- AIt documents the organization’s existing cybersecurity outcomes.Correct answer
- BIt defines the desired future state of cybersecurity.
- CIt establishes the organization’s risk appetite.
- DIt serves as a compliance checklist for regulations.
Why this is the answer
The Current Profile answers 'Where are we now?' by mapping current practices to the Framework Core outcomes. It is a snapshot of what is currently implemented, not the desired state (Target Profile) nor risk appetite.
Framework Core - Identify Function
8 questions in this domain
- Question 5Single Choice
According to the NIST CSF, what is the foundational prerequisite before implementing any cybersecurity controls?
- AEstablishing a complete and accurate asset inventoryCorrect answer
- BDeploying a firewall at the network perimeter
- CConducting a vulnerability scan on all systems
- DInstalling endpoint protection software on all workstations
Why this is the answer
Asset Management (ID.AM) is the foundational discipline under the Identify function. Without knowing what assets exist, their classification, and ownership, no other cybersecurity activity (Protect, Detect, Respond) can be effectively performed. The framework emphasizes that you cannot protect what you do not know.
- Question 6Multiple Select
Which of the following are key components of Asset Management (ID.AM) as defined in the NIST CSF? (Select two answers)
- AAsset InventoryCorrect answer
- BAsset OwnershipCorrect answer
- CThreat Identification
- DVulnerability Scanning
Why this is the answer
Asset Management (ID.AM) encompasses asset inventory, classification, and ownership. Threat Identification belongs to Risk Assessment (ID.RA), and vulnerability scanning is part of the Protect or Detect functions, not a core ID.AM component.
- Question 7Interactive
Review the following CSV excerpt representing an asset inventory. According to NIST CSF Asset Management (ID.AM), which assets are missing an assigned owner? (Select all that apply)
- AServer1
- BServer2Correct answer
- CDatabase
- DContractor JohnCorrect answer
Why this is the answer
Asset ownership is a requirement under ID.AM. In the inventory, Server2 and Contractor John have no owner listed, making them non-compliant. Server1 and Database already have designated owners.
- Question 8Single Choice
Which Business Environment (ID.BE) subcategory requires an organization to define its role and dependencies within the supply chain?
- AID.BE-1Correct answer
- BID.BE-2
- CID.BE-3
- DID.BE-4
Why this is the answer
ID.BE-1 is defined as 'Organizational role in supply chain'. ID.BE-2 refers to critical infrastructure place, ID.BE-3 deals with mission objectives, and ID.BE-4 covers dependencies and critical functions. Only ID.BE-1 explicitly addresses supply chain role.
- Question 9Multiple Select
Which of the following activities belong to the Governance (ID.GV) category of the NIST CSF Identify function? (Select two answers)
- AApproving the cybersecurity policyCorrect answer
- BInstalling network firewalls
- CIdentifying legal and regulatory requirementsCorrect answer
- DConducting penetration tests
Why this is the answer
ID.GV includes policy approval (board-level governance) and identification of legal/regulatory requirements. Installing firewalls is a Protect function activity, and penetration testing belongs to Risk Assessment (ID.RA) or Detect, not Governance.
- Question 10Interactive
Examine the following list of activities. Based on the NIST CSF, which one is NOT part of Risk Assessment (ID.RA)?
- AThreat Identification
- BVulnerability Analysis
- CControl ImplementationCorrect answer
- DImpact Analysis
Why this is the answer
Risk Assessment (ID.RA) involves threat identification, vulnerability analysis, and impact analysis. Control implementation belongs to the Protect function (PR) and is not part of ID.RA.
- Question 11Single Choice
In the NIST CSF, what is the primary difference between risk appetite and risk tolerance?
- ARisk appetite is broad and strategic; risk tolerance is specific and often quantitativeCorrect answer
- BRisk appetite is set by the CISO; risk tolerance is set by the board
- CRisk appetite is measured in dollars; risk tolerance is measured in hours
- DThere is no difference; the terms are interchangeable
Why this is the answer
Risk appetite is a high-level, strategic statement of willingness to accept risk, typically set by senior leadership. Risk tolerance is the specific, measurable threshold applied to individual risks and is derived from the appetite. The NIST emphasizes this distinction in ID.RM.
- Question 12Multiple Select
Which of the following are recognized subcategories of Supply Chain Risk Management (ID.SC) in the NIST CSF? (Select two answers)
- AID.SC-1: Cyber Supply Chain Risk Management ProgramCorrect answer
- BID.SC-2: Third-party Dependencies IdentificationCorrect answer
- CID.AM-1: Asset Inventory
- DID.RA-3: Threat Identification
Why this is the answer
ID.SC-1 and ID.SC-2 are specific subcategories of Supply Chain Risk Management. ID.AM-1 belongs to Asset Management, and ID.RA-3 belongs to Risk Assessment, not to ID.SC.
