Q1. Which affinity value will be matched by the affinity bit mask of the affinity 0xFF00000A mask 0xFFFF000F command?

A. 0xFFFF000A

B. 0xFF00EEEA 

C. 0xFF000000 

D. 0x00000000 

E. 0x11110001

Answer: B

Q2. Which statement is correct regarding the default MPLS TTL behavior?

A. When an ingress edge LSR receives an IP packet, it will decrement the IP TTL field by

1; then it will set the MPLS Label TTL field to 255.

B. When an ingress edge LSR receives an IP packet, it will decrement the IP TTL field by 1; then it will copy the decremented IP TTL field into the MPLS Label TTL field.

C. When an ingress edge LSR receives an IP packet, it will just copy the IP TTL field into the MPLS Label TTL field.

D. When an ingress edge LSR receives an IP packet, it will copy the IP TTL field into the MPLS Label TTL field first; then it will only decrement the MPLS Label TTL field by 1.

E. When an ingress edge LSR receives an IP packet, it will copy the IP TTL field into the MPLS Label TTL field first; then it will only decrement the IP TTL field by 1.

Answer: B

Q3. You are tasked to enable LDP on many of the interfaces on the Cisco CRS-3 router, and because there are many interfaces that need to have LDP enabled, you mistakenly did not enable LDP on all the required interfaces. To prevent this issue from happening again in the future, what could you do the next time you need to enable LDP on many interfaces?

A. use the mpls ldp auto-config command under the IGP routing process

B. use the mpls ldp sync command under the IGP routing process

C. use the interface all command under the MPLS LDP process

D. use the discovery command under the MPLS LDP process

Answer: A

Q4. On the Cisco IOS XR, which MQC configuration is different than on the Cisco IOS and IOS XE?

A. On the Cisco IOS XR, WRED can only be applied in the output direction.

B. On the Cisco IOS XR, marking can only be applied in the input direction.

C. On the Cisco IOS XR, LLQ can be applied in the input or output direction.

D. On the Cisco IOS XR, LLQ can use up to four priority queues: level 1, level 2, level 3, and level 4.

Answer: C

Q5. With unmanaged CE routers, at which point in the service provider network is the QoS trust boundary, and what is required at the trust boundary?

A. between the CE and PE router and mapping of the customer traffic classes into the service provider traffic classes at the PE router ingress

B. between the CE and PE router and trusting the QoS markings from the CE router and applying the required QoS mechanisms based on the customer QoS markings

C. between the PE and the P router and mapping of the customer traffic classes into the

service provider traffic classes at the P router ingress

D. between the PE and P router and trusting the QoS markings from the CE router and applying the required QoS mechanisms based on the customer QoS markings

E. between the customer network and the CE router ingress and applying the required egress QoS policy on the CE router

Answer: A

Q6. Which three conditions can occur when metering traffic using a dual token bucket traffic policing QoS mechanism on Cisco routers? (Choose three.)

Q8. Cisco MPLS TE resource attributes that are configured locally for each link are distributed to the headend router of the traffic engineering tunnel using which protocol?

A. BGP

B. MP-BGP

C. LDP

D. RSVP

E. OSPF or IS-IS with TE extension

Answer: E

Q9. On Cisco routers, how is hierarchical QoS implemented?

A. Within the parent policy, reference another child policy using the policy-map command.

B. Within the child policy, reference another parent policy using the policy-map command.

C. Use the policy-map command within a service-policy to implement nested policy-maps.

D. Within the parent policy-map, reference another child policy-map using the service- policy command.

Answer: D

Q10. When implementing MPLS TE tunnels on Cisco IOS XR routers, what is the tunnel setup and hold priority value range, and which value has the highest priority?

A. 0-63, where 0 is the highest priority

B. 0-63, where 63 is the highest priority

C. 0-7, where 0 is the highest priority

D. 0-7, where 7 is the highest priority

Answer: C
