Answer: 


Q2. A service provider is designing control policies at the customer edge of the network, in order to prevent usage that exceeds the contracted terms A new client that is contracted for only 2 Gbps is connecting to the service provider edge with a 10 Gbps interface. Which two OoS strategies meet the design goal? (Choose two.) 

A. On the customer edge device, enable policing on the interface that is connected to the service provider. 

B. On the service provider edge, enable WRED on the customer port. 

C. On the customer edge, enable WRED on the interface that is connected to the service provider 

D. I On the service provider edge, enable policing on the customer port 

E. the customer edge device, enable traffic shaping on the interface that is connected to the service provider. 

F. C On the service provider edge, enable traffic shaping on the customer port 

Answer: D,E 


Q3. Refer to the exhibit. 

An ISP engineer has been asked to identity a method to protect the PE and to control the number of BGP prefixes learned from his customers. The BGP session should be dropped if the PE router receives more than 1000 BGP prefixes. A syslog message should be generated when the number of BGP prefixes learned from CE exceeds 850. 

Which Cisco IOS command should the engineer apply on PE routers? 

A. neighbor 10.1.1.2 maximum-prefix 1000 85 

B. neighbor 10.1.1.2 maximum-prefix 1000 850 

C. neighbor 10.1.1.2 maximum-prefix 1000 85 warning-only 

D. neighbor 10.1.1.2 maximum-prefix 1000 850 warning-only 

Answer: A 


Q4. Refer to the exhibit. 

OSPF is already running with the default OSPF parameters. R1 has added a new subnet (loopback 11). What will occur in regards to SPT computing on R2 router? 

A. Adding ispf command on R2 router, the entire SPT will be computed on R2 router. 

B. Because 10.11.11.11/32 prefix information will be in a LSA type 3 on R2 router's OSPF database, R2 router will run partial SPF computation. 

C. Adding ispf command on R2 router, R2 router will recompute only the affected part of tree. 

D. Because 10.11.11.11/32 prefix will be a LSA type 1 on R2 router's OSPF database. R2 router will always run a full SPF computation, even though an OSPF optimization is applied on R2 router. 

Answer: C 


Q5. Network Operations team has configured the routers with the logging buffered warnings command. Which three severity levels appear in the router syslog? (Choose three.) 

A. errors 

B. notifications 

C. informational 

D. alerts 

E. debugging 

F. emergencies 

Answer: A,D,F 


Q6. Which two statements about Unified MPLS are true? (Choose two.) 

A. Unified MPLS works on Cisco IOS XR Software only. 

B. Unified MPLS extends MPLS across multidomain networks in a scalable manner. 

C. New technologies or protocols are not used; only MPLS, LDP, IGP, and BGP are used. 

D. ABR loopback prefixes should always be redistributed from the core IGP into the aggregation IGP. 

E. The RRs are part of the control path only. 

Answer: B,D

Q7. A Service Provider is designing control policies at the customer edge of the network, in order to prevent usage that exceeds the contracted terms. A new client that is contracted for only 2 Gbps is connecting to the Service Provider edge with a 10 Gbps interface. Which two QoS strategies meet the design goal? (Choose two.) 

A. On the service Provider edge, enable traffic shaping on the customer port. 

B. On the customer edge device, enable traffic shaping on the interface that is connected to the Service Provider. 

C. On the customer edge device, enable policing on the interface that is connected to the Service Provider. 

D. On the service Provider edge, enable policing on the customer port. 

E. On the service Provider edge, enable WRED on the customer port. 

F. On the customer edge, enable WRED on the interface that is connected to the Service Provider. 

Answer: B,D

Q8. Refer to the exhibit. 

The prefix 10.1.1.64/28 should be advertised to the PE router, yet the prefix is not being received by the PE. Which configuration should be applied on CE in order to fix this issue? 

A. jp prefix-list ROUTES_TO_SP seq 1 permit 10.1.1.64/28 

B. router bgp 65000 no network 10.1.1.64 mask 255.255.255.240 network 10.1.1.128 mask 255.255.255.128 

C. ip prefix-list ROUTES_TO_SP permit 10.1.1.64/28 

D. router bgp 65000 no network 10.1.1.64 mask 255.255.255.240 network 10.1.1.0 mask 255.255.255.0 

Answer: A
