CCIE Service Provider MPLS Traffic Engineering

1. What is the purpose of the 'metric' parameter in MPLS TE tunnel configuration?

To override the OSPF cost for traffic using the tunnel

To set the bandwidth requirement

To configure the tunnel priority

To define link affinity values

2. In MPLS TE, what is the function of a 'path protection' tunnel?

To provide an alternate end-to-end path in case the primary tunnel fails

To protect individual links within a tunnel

To encrypt the primary tunnel

To increase the tunnel's bandwidth

3. Which OSPF extension carries MPLS TE traffic engineering information?

OSPF Opaque LSA Type 10

OSPF Opaque LSA Type 11

OSPF Area Scope LSA

OSPF External LSA

4. What is the purpose of MPLS TE link protection (link FRR)?

To provide local fast reroute around a failed link without headend involvement

To prevent all link failures

To encrypt traffic on protected links

To increase link bandwidth

5. In MPLS TE, what does the 'hold priority' parameter control?

Which tunnels can be preempted by higher-priority tunnels

The tunnel setup time

The backup path priority

The encryption level of the tunnel

6. Which feature allows an MPLS TE tunnel to automatically reroute around congestion?

Adaptive MPLS TE

Tunnel reoptimization

Dynamic bandwidth adjustment

CSPF recalculation

7. In MPLS TE, what is the 'setup priority' used for?

To determine which tunnels can preempt others during resource contention

To set the QoS class of the tunnel

To configure tunnel encryption

To define the tunnel's backup path

8. What is the primary advantage of using MPLS TE with segment routing?

Simplified path encoding without per-tunnel state at every hop

Increased bandwidth utilization

Elimination of RSVP signaling

Better encryption of traffic

9. Which command configures the bandwidth for an MPLS TE tunnel on Cisco IOS?

Tunnel bandwidth

Tunnel mpls traffic-eng bandwidth

Bandwidth reservation

Tunnel qos bandwidth

10. In MPLS TE, what does 'loose hop' mean in the explicit route?

The path can use any intermediate router to reach the next hop

The path must go directly to the specified router

The path is optional and can be ignored

The path uses only backup links

11. What is the primary purpose of MPLS Traffic Engineering in a service provider network?

To encrypt all traffic flowing through the network

To optimize bandwidth utilization and enable constraint-based routing

To replace BGP as the primary routing protocol

To eliminate the need for OSPF in the network

12. Which statement is true about auto-tunnel backup in MPLS TE?

It automatically creates point-to-point backup tunnels for FRR

It requires manual configuration of all backup tunnels

It only works with OSPF

It eliminates the need for link affinities

13. In MPLS TE, what is the purpose of the 'bandwidth reservation' attribute?

To ensure QoS for specific traffic flows

To prevent other tunnels from using reserved bandwidth

To set the speed of the physical link

To configure tunnel encryption

14. Which RSVP message type is used to establish an MPLS TE tunnel?

RESV

PATH

HELLO

NOTIFY

15. What does CSPF stand for in MPLS TE?

Constrained Shortest Path First

Core Service Provider Framework

Cisco Service Provider Function

Constraint Signaling Protocol Format

16. In MPLS TE Fast Reroute, what is a 'detour'?

An alternate path that bypasses a failed link or node

A secondary tunnel running parallel to the primary tunnel

A backup routing table

An OSPF neighbor relationship

17. Which mechanism allows MPLS TE tunnels to recover from link failures within milliseconds?

BFD (Bidirectional Forwarding Detection)

Fast Reroute (FRR)

Graceful Restart

Non-Stop Forwarding (NSF)

18. What is the maximum number of hops in an MPLS TE tunnel by default?

15

32

64

255

19. In MPLS TE, what does the term 'affinity' refer to?

The preference for certain link types in path calculation

The speed of the interface

The MTU size of the link

The administrative distance of the route

20. Which protocol is used to distribute MPLS TE information across the network?

IS-IS with TE extensions

OSPF with TE extensions

Both IS-IS and OSPF with TE extensions

BGP exclusively
