350-501 Security and Services Practice Question
A service provider is implementing RPKI to validate BGP routes. Which THREE components are necessary for a complete RPKI deployment on routers? (Choose three)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
RPKI cache server (Relying Party)
RPKI requires three components: Route Origin Authorization (ROA) records created by RIRs to authorize AS origins, an RPKI cache server (Relying Party) that collects ROAs and validates them, and the BGP Origin Validation feature on routers that uses the Relying Party's VRP data to filter invalid routes. The cache server communicates with routers via RTR protocol. Components like prefix-lists or local preference manipulation are not part of RPKI itself.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
RPKI cache server (Relying Party)
Why this is correct
Correct. The RPKI cache server (Relying Party) aggregates ROAs and serves validated prefix-to-AS mappings (VRP) to routers.
- ✓
Route Origin Authorization (ROA)
Why this is correct
Correct. ROAs are the cryptographic records that authorize an AS to originate specific prefixes.
- ✗
Prefix-list for filtering
Why it's wrong here
Incorrect. While prefix-lists can be used for filtering, they are not a component of RPKI deployment; RPKI uses VRP data instead.
- ✗
BGP path manipulation using local preference
Why it's wrong here
Incorrect. BGP path manipulation using local preference is a routing policy tool, not required for RPKI origin validation.
- ✓
BGP Origin Validation feature on routers
Why this is correct
Correct. The BGP Origin Validation feature on routers uses the VRP downloaded from the RPKI cache to validate the origin AS of received routes.
