SDM 2002001050 SDM Certification NI Practice Exam
**Question 1. Which ITIL lifecycle stage aligns most closely with the SDM “Design”
phase?**
A) Service Strategy
B) Service Transition
C) Service Operation
D) Continual Service Improvement
Answer: B
Explanation: The SDM “Design” phase focuses on defining service specifications
and translating requirements into a deployable model, which corresponds to ITIL’s
Service Transition stage that prepares services for live operation.
**Question 2. In the TM Forum eTOM framework, the process that matches the
SDM “Catalog Management” function is:**
A) Order Handling
B) Service Management
C) Resource Management
D) Product Lifecycle Management
Answer: D
Explanation: eTOM’s Product Lifecycle Management encompasses product
(service) definition, publishing, and retirement, mirroring SDM’s Catalog
Management responsibilities.
**Question 3. Which component of the SDM data model links a Customer Service
to the underlying Network Resources?**
, SDM 2002001050 SDM Certification NI Practice Exam
A) Service Parameter Set
B) Resource Service
C) Service Dependency Matrix
D) Inventory Mapping Table
Answer: B
Explanation: The Resource Service acts as the bridge that associates a logical
Customer Service with the physical or virtual network resources required for its
delivery.
**Question 4. Parameterization in SDM primarily enables:**
A) Fixed, one‑size‑fits‑all service offerings
B) Dynamic, mass‑customized service configurations
C) Manual entry of every service attribute
D) Removal of all optional service features
Answer: B
Explanation: By defining parameters and options, SDM can generate many
variations of a service without redesigning the model, supporting mass
customization.
**Question 5. The SDM abstraction layer presents network resources to the
fulfillment engine as:**
A) Vendor‑specific CLI commands
B) A normalized, technology‑agnostic view
, SDM 2002001050 SDM Certification NI Practice Exam
C) Raw hardware schematics
D) Unstructured text files
Answer: B
Explanation: The abstraction layer hides vendor‑specific details, exposing
resources in a consistent, normalized format that the fulfillment logic can
consume.
**Question 6. Which protocol is most commonly used for real‑time inventory
synchronization between SDM and a Network Inventory System?**
A) FTP
B) SNMP
C) NETCONF
D) HTTP GET only
Answer: C
Explanation: NETCONF provides a standardized, transaction‑based mechanism for
synchronizing configuration and inventory data between SDM and underlying
network systems.
**Question 7. Order decomposition in SDM transforms a single customer order
into:**
A) A monolithic batch job
B) Multiple independent service orders and tasks
C) A single SOAP message to the OSS
, SDM 2002001050 SDM Certification NI Practice Exam
D) A static PDF invoice
Answer: B
Explanation: Decomposition splits the high‑level request into discrete, executable
service orders and tasks that can be orchestrated in parallel or sequence.
**Question 8. In the SDM orchestration engine, a “conditional branching”
element is used to:**
A) Randomly select a network device
B) Execute tasks only when specific criteria are met
C) Duplicate all tasks for redundancy
D) Disable logging for performance reasons
Answer: B
Explanation: Conditional branching evaluates runtime data (e.g., resource
availability) and determines whether subsequent tasks should run.
**Question 9. A compensation routine in fulfillment failure handling is triggered
when:**
A) The order is successfully completed
B) A task fails after partial resource allocation
C) The customer logs into the portal
D) The system clock is synchronized
Answer: B
