User A wants to obtain a better network service for business development and signs an SLA with a carrier. User A purchases a bandwidth of 5 Mbit/s to ensure the voice service (requiring short delay), video service, key data services, and other services.
If you were the carrier’s network administrator, what would you do on the PE to ensure these services?
A . Mark the VoIP service as EF, set the CIR to 1 Mbit/s, and set the PIR to 1 Mbit/s; mark the video service as AF4, set the CIR to 2 Mbit/s, and set the PIR to 2 Mbit/s; mark key data services as AF1, set the CIR to 2 Mbit/s, and the PIR to 5 Mbit/s; mark other services as BE, set the CIR to 0 Mbit/s, and set PIR to 5 Mbit/s.
B . Mark the VoIP service as AF4, set the CIR to 0 Mbit/s, and set the PIR to 1 Mbit/s; mark the video service as EF and set the CIR and PIR to 5 Mbit/s; mark key data services as AF3, set the CIR to 2 Mbit/s, and the PIR to 5 Mbit/s; mark other services as BE, set the CIR to 0 Mbit/s, and set PIR to 2 Mbit/s.
C . Mark the VoIP service as EF and set the CIR and PIR to 2 Mbit/s; mark the video service as AF3 and set the CIR and PIR to 2 Mbit/s; mark key data services as AF4, set the CIR to 2 Mbit/s, and the PIR to 5 Mbit/s; mark other services as BE, set the CIR to 0 Mbit/s, and set PIR to 5 Mbit/s.
D . Mark the VoIP service as EF, set the CIR to 0 Mbit/s, and set the PIR to 1 Mbit/s; mark the video service as AF4 and set the CIR and PIR to 2 Mbit/s; mark key data services as AF3, set the CIR to 1 Mbit/s, and the PIR to 5 Mbit/s; mark other services as AF1, set the CIR to 2 Mbit/s, and set PIR to 5 Mbit/s.
