350-501 Architecture Practice Question
An ISP wants to create separate virtual networks over a shared physical infrastructure to serve mobile broadband (eMBB), IoT (mMTC), and mission-critical services (uRLLC). Which technology enables this segmentation with per-slice resource guarantees?
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
✓
Network Slicing using IETF and 3GPP frameworks
Network slicing divides the physical network into multiple virtual networks, each with dedicated resources for different service types. L3VPN, MPLS-TE, and VPLS do not provide per-slice resource guarantees natively.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
MPLS Traffic Engineering
Why it's wrong here
TE provides path optimization but not complete network slicing.
- ✗
L3VPN with VRF
Why it's wrong here
VRF provides logical separation but not resource guarantees.
- ✗
VPLS
Why it's wrong here
VPLS is for L2VPN, not resource slicing.
- ✓
Network Slicing using IETF and 3GPP frameworks
Why this is correct
Network slicing provisions isolated virtual networks with dedicated resources.
