2. In Carrier Ethernet, EBS (Excess Burst Size) allows traffic to exceed which parameter?

CIR only

PIR only

CIR and PIR combined

Frame size limit

3. What is the primary role of CoS (Class of Service) marking in Carrier Ethernet frames?

To identify the customer location

To prioritize traffic within the network

To encrypt sensitive data

To reduce frame size

4. Which Ethernet service type provides any-to-any connectivity among multiple sites?

EPL

EVPL

E-LAN

E-Line

5. In the context of Carrier Ethernet, what does 'oversubscription' mean?

Offering more bandwidth than physically available

Purchasing excess SLA capacity

Adding redundant links

Increasing frame transmission rates

6. Which QoS mechanism in Carrier Ethernet prioritizes traffic based on defined classes?

Best effort delivery

Priority queuing (PQ)

Random early detection (RED)

Traffic shaping only

7. In Carrier Ethernet, what is the function of a NNI (Network-to-Network Interface)?

Connects customer to the network

Connects two carrier networks or network segments

Manages VLAN tags only

Encrypts inter-carrier traffic

8. Which of the following is a characteristic of Ethernet Private Line (EPL)?

Supports multiple customer VLANs

Dedicated point-to-point connection with fixed bandwidth

Allows burst traffic above CIR

Supports multipoint connectivity

9. In Carrier Ethernet, VLAN stacking (QinQ) primarily enables which capability?

Doubling the frame size

Isolating multiple customer VLANs over a single UNI

Increasing frame transmission speed

Reducing latency across links

10. What is the primary purpose of traffic policing in Carrier Ethernet?

To encrypt customer data

To ensure traffic conforms to SLA parameters

To increase network bandwidth

To eliminate VLAN tags

11. Which Ethernet service provides point-to-point connectivity with bandwidth guaranteed between two customer locations?

Ethernet Private Line (EPL)

Ethernet Virtual Private Line (EVPL)

Ethernet Multipoint (EP)

Ethernet LAN (ELAN)

12. In a Carrier Ethernet network, what does an SLA (Service Level Agreement) typically guarantee?

Zero packet loss

Bandwidth, latency, and availability

Only uptime

Unlimited throughput

13. What is the primary advantage of using MPLS in Carrier Ethernet networks?

Increases frame size

Enables traffic engineering and QoS guarantees

Eliminates the need for routing

Reduces bandwidth requirements

14. Which Ethernet service enables multipoint-to-multipoint connectivity with hub-and-spoke topology?

EPL

EVPL

E-Tree

15. In Carrier Ethernet, which frame tag is used to identify customer traffic across the provider network?

S-Tag (Service Tag)

C-Tag (Customer Tag)

QoS Tag

Priority Tag

16. What does CIR stand for in the context of traffic management?

Carrier Interface Rate

Committed Information Rate

Circuit Integration Rate

Carrier Identification Record

17. Which Ethernet service supports multiple VLANs and allows customers to define their own VLAN tags?

EPL

EVPL

E-LAN

E-Tree

18. In Carrier Ethernet, what is the purpose of a UNI (User Network Interface)?

To connect two carrier networks

To define the boundary between customer and carrier networks

To manage QoS within the carrier cloud

To encrypt traffic between sites

19. Which of the following best describes a Metro Ethernet Network (MEN)?

A WAN connecting only metropolitan areas

A network providing Ethernet services within a metropolitan area

A LAN limited to city boundaries

A backbone network for ISPs only

20. What does MEF stand for in the context of Carrier Ethernet?

Metro Ethernet Federation

Metro Ethernet Forum

Metropolitan Ethernet Foundation

Metro Ethernet Framework
