350-501 Services Practice Question
A service provider is planning to offer L2VPN services using MPLS. Which TWO statements are true regarding Ethernet over MPLS (EoMPLS) and Virtual Private LAN Service (VPLS)?
⚠ Common exam trap
Cisco often tests the distinction between point-to-point (EoMPLS) and multipoint (VPLS) services, and the trap here is confusing MAC learning (VPLS) with simple transport (EoMPLS), or assuming VPLS uses a hub-and-spoke topology instead of a full mesh.
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
✓
EoMPLS provides a point-to-point pseudowire between two PE routers.
EoMPLS (Ethernet over MPLS) is correct because it establishes a point-to-point pseudowire (Martini draft, RFC 4448) between two PE routers, transporting Layer 2 Ethernet frames across an MPLS core without MAC learning or multipoint capabilities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
EoMPLS provides a point-to-point pseudowire between two PE routers.
Why this is correct
EoMPLS is a point-to-point service.
- ✗
VPLS requires all PE routers to be in the same VLAN.
Why it's wrong here
VPLS uses bridge domains, not necessarily the same VLAN.
- ✗
VPLS uses a hub-and-spoke topology to interconnect multiple sites.
Why it's wrong here
VPLS uses a full-mesh of pseudowires.
- ✓
VPLS emulates a multipoint Ethernet service over MPLS.
Why this is correct
VPLS provides a multipoint service.
- ✗
EoMPLS supports MAC address learning between sites.
Why it's wrong here
EoMPLS does not perform MAC learning.

Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
