MPLS VPN Quiz: WAN Edge Router Functions (CCNA)
Quick, free edge router functions quiz. Instant results.
This MPLS VPN quiz helps you identify the three key functions of a WAN edge router, including path selection, secure tunneling, and traffic shaping. For a deeper look at tunnels, check the vpn tunneling quiz, and build exam confidence with the CCNA practice exam; you can also review switching basics with the stp quiz.

Distinguish WAN edge router features from other router types to clarify their unique roles in network design and ccna exam prep.
- Analyze Traffic Management Roles -
Examine how WAN edge routers handle packet forwarding, traffic shaping, and redundancy, helping you master wan edge router features in real-world scenarios.
- Apply Concepts to CCNA 4 Practice Quiz -
Use your understanding of WAN edge functions to accurately answer ccna 4 practice quiz questions and simulate the pressure of the ccna final exam questions.
- Evaluate Scenario-Based Configurations -
Assess network scenarios to determine the appropriate WAN edge router functions, boosting your confidence for CCNA exam prep and real deployments.
Cheat Sheet
- Routing & Path Selection -
WAN edge routers use dynamic routing protocols like OSPF and BGP to build and maintain the best paths across multiple service provider links. Understanding OSPF cost calculations (Cost = Reference Bandwidth / Interface Bandwidth) helps you predict failover behavior. Mnemonic: "Big Only Sees Perfect Routes" for BGP, OSPF, Static, Policy-based routing.
- Traffic Prioritization with QoS -
Quality of Service on a WAN edge router classifies, marks, and shapes traffic to guarantee performance for critical applications. For example, you can map voice RTP to DSCP EF (Expedited Forwarding) to ensure low jitter. Remember "PMP" for QoS tasks: Polynomial shaping, Marking, Policing.
- WAN Encapsulation & Link Technologies -
Edge routers support encapsulation methods such as PPP, HDLC, and Frame Relay to interoperate with diverse service provider networks. Review PPP authentication options (PAP vs. CHAP) to secure link establishment. A handy phrase: "FH²P" (Frame, HDLC, PPP) for common WAN edge router features.
- Security Services & VPN Integration -
Implementing site-to-site IPsec VPN and ACL filtering on a WAN edge router protects data traversing public infrastructure. Practice configuring transform sets, crypto maps, and verify with show crypto ipsec sa for your CCNA 4 practice quiz. Tip: "A”VIP" for ACLs, VPN, Inspection, and Policy-based routing as key security functions.
- High Availability & Redundancy -
Edge routers often run HSRP or VRRP to provide seamless failover between redundant devices, keeping voice and data sessions live. Validate your setup with show standby and track interface commands. Think "FAR" (Failover, Availability, Redundancy) to nail ccna final exam questions on WAN edge resiliency.
