Implementing and Operating Cisco Service Provider Network Core Technologies (350-501 SPCOR) Questions and Answers

Question 69

Refer to the exhibit. An Ethernet access provider is configuring routers PE-1 and PE-2 to provide E-Access EVPL service between UNI and ENNI. ENNI service multiplexing is based on 802.1ad tag 150, and service-multiplexed UNI is based on 802.1q tag 10. Which EFP configurations must the provider implement on PE-1 and PE-2 to establish end-to-end connectivity between CE-1 and CE-2?

Options:

A.

On PE-1:

interface GigabitEthernet2

service instance 100 ethernet

encapsulation dot1ad 150

rewrite ingress tag pop 1 symmetric

On PE-2:

interface GigabitEthernet2

service instance 2 ethernet

encapsulation dot1q 10

B.

On PE-1:

interface GigabitEthernet2

service instance 100 ethernet

encapsulation dot1q 150

rewrite ingress tag pop 1 symmetric

On PE-2:

interface GigabitEthernet2

service instance 2 ethernet

encapsulation dot1q 10

C.

On PE-1:

interface GigabitEthernet2

service instance 100 ethernet

encapsulation dot1ad 150 dot1q 10

rewrite ingress tag pop 2 symmetric

On PE-2:

interface GigabitEthernet2

service instance 2 ethernet

encapsulation dot1q 10

D.

On PE-1:

interface GigabitEthernet2

service instance 100 ethernet

encapsulation dot1ad 150

rewrite ingress tag pop 1 symmetric

On PE-2:

interface GigabitEthernet2

service instance 2 ethernet

encapsulation dot1q 10

rewrite ingress tag pop 1 symmetric

Question 70

Refer to the exhibit Routers R1 and R2 are connected via a señal link and use the IS-IS routing protocol for route exchange After a configuration change on R2. IS-IS connectivity is interrupted A network engineer confirmed that the interfaces are in the UP state and connectivity exists between the two routers. Which two actions must the engineer perform to resolve the problem? (Choose two.)

Options:

A.

Disable padding for hello packets under the serial interface on R2 DUMPS

B.

Change the hello interface timer to 10 seconds on R1.

C.

Change the MTU to 1500 bytes on R2.

D.

Enable hello packet padding globally on R1.

E.

Change R2 to an IS-IS Level 1 router.

Question 71

A network engineer is implementing BFD configuration changes on a customer's equipment. How is the bfd interval configuration on the interface disconnected?

Options:

A.

The status of the interface changes.

B.

The IPv4 or IPv6 address configuration on the interface changes.

C.

It is automatically disconnected when the BFD-configured subinterface is removed.

D.

It is automatically disconnected when the BFD main interface is removed.

Question 72

An ISP that provides private network services across the country has recently migrated their infrastructure to support MPLS technology. A network engineer configured mpls ip on all routers and implemented the OSPF routing protocol with TE extensions in the backbone area. The ISP wants to ensure that label exchange is performed only on MPLS-enabled interfaces that are associated with the IGP instance.

Which action must the engineer take to accomplish the goal?

Options:

A.

Enable Cisco Express Forwarding on all routers in the backbone area.

B.

Implement mpls Idp sync on all routers in the segment.

C.

Update the routers in the segment to use RSVP-TE for label distribution.

D.

Implement mpls Idp autoconfig on all routers in the segment.
