  A. Deploy MPLS TE

  B. Enable BGP Flowspec

  C. Enable NSF/GR for OSPF

• Question 35:

  You are redesigning an OSPF network that currently uses RFC 1918 Class A address space to optimize its convergence time. The entire network consists of point-to-point interfaces between routers.

  Which reason is the best reason to implement topology summarization in this network?

  A. to optimize CEF entry allocation

  B. to optimize RIB entry allocation

  C. to reduce the number of neighbor relationships

  D. to reduce link state database size

  Correct Answer: D

• Question 36:

  Which two design characteristics of Resilient Ethernet Protocol on a Metro Ethernet infrastructure are true? (Choose two.)

  A. Resilient Ethernet Protocol provides fast convergence on Layer 2 ring domains

  B. Unidirectional Link Detection Protocol can be used in combination with Resilient Ethernet Protocol

  C. Resilient Ethernet Protocol cannot load balance VLAN traffic across a ring

  D. Resilient Ethernet and Spanning Tree Protocol can reside on the same switch and on the same port

  E. Resilient Ethernet Protocol and Spanning Tree Protocol rings or domains can share a common link

  Correct Answer: AB

• Question 37:

  Refer to the exhibit. The service provider ACME Internet just added a 100 Gbps peering in Paris to use as the default for inbound traffic from Very Big ISP.

  Which routing policy achieves the desired outcome?

  

  A. Apply an export policy in New York and Tokyo that adds a Weight attribute to routes send to Very Big ISP via Paris

  B. Apply an export policy that only permits a default route in Brussels and Zurich

  C. Use traffic engineering by injecting a preferred LocalPref attribute to routes advertised to Very Big ISP in Paris

  D. Apply an export policy in Paris by applying a MED or Community attribute with a preference that Very Big ISP acts upon

  Correct Answer: D

• Question 38:

  Which two statements define some of the general characteristics of SDN? (Choose two.)

  A. Southbound interfaces are interfaces used between the control plane and the date plane.

  B. OpenFlow isconsidered one of the first Northbound APIs used by SDN controllers.

  C. Northbound interfaces are open interfaces used between the control plane and the date plane.

  D. The separation of the control plane from the data plane.

  E. OVSDB is an application database management protocol.

  Correct Answer: AE

• Question 39:

  

  Refer to the exhibit. Company ABC is a Tier 3 service provider that offers Layer 2 and Layer 3 transport for small/medium enterprise customers in the US. Most of their network is built on Layer 2 MPLS circuits from a Tier 1 provider. Many Company ABC customers are using overlay VPN technologies and independent routing protocols, and they are affected with unacceptable convergence time after every major outage in the core of the Tier 1 provider.

  Which long-term redesign increases network availability?

  A. Customers replace their own overlay VPN service with the Company ABC Layer 3 VPN service.

  B. Customers fine tune their routing protocol for faster convergence

  C. Company ABC replaces the Layer 2 MPLS circuit from the Tier 1 service provider with dark fiber/DWDM-based transport.

  D. Company ABC should adopt a full-mesh POP connectivity.

  Correct Answer: D

• Question 40:

  What is a benefit of Control Plane Policing?

  A. CPP protects the forwarding plane by allowing legitimate traffic and dropping excessive traffic

  B. CPP protects the forwarding plane by rate-limiting excessive routingprotocol traffic

  C. CPP can protect the control plane from reconnaissance and or denial-of-service attacks

  D. CPP drops malformed packets that are sent to the CPU

  Correct Answer: C
