• Question 551:

  Users are complaining of intermittent high packet loss for seconds at a time. The engineer troubleshooting the issue finds that a TenGigE link is bouncing for milliseconds at a time, causing the traffic path to reconverge onto a congested FastEthernet link. What can the engineer do to prevent service-affecting reconvergence only in the case of momentary link bounces until the link can be repaired?

  A. Increase the Value of the carrier-delay down.
  B. Disable keepalives and BFD.
  C. Decrease the value of the carrier-delay up.
  D. Decrease the value of the carrier-delay down.
  E. Increase the value of the carrier-delay up.
  E. Increase the value of the carrier-delay up.

• Question 555:

  A service provider network engineer is defining a Qos architecture with the following requirements :

  *The service provider does not provide managed CPE services.

  *Customer throughput of both connection-oriented and non-connection-oriented must be managed.

  *The service provider network capacity must be protected by limiting customer traffic to the purchased circuit bandwidth.

  *Latency-sensitive traffic must be accommodated.

  Which recommendation is the network engineer defining?

  A. The service provider must shape traffic that is outbound on the PE interface
  B. The service provider must shape traffic that is inbound on the PE interface
  C. The Customer must shape all traffic that is outbound on the CE interface
  D. The service provider must police traffic that is inbound on the PE interface
  E. The service provider must police traffic that is outbound on the PE interface
  F. The customer must police all traffic that is outbound on the CE interface
  D. The service provider must police traffic that is inbound on the PE interface

• Question 556:

  The layer 2 protocol used by POS technology offers a standardized way for mapping IP packets into SONET/ SDH payloads. Select the correct sequence of POS operation:

  1) Data is scrambled and synchronous mapping takes place by octet into the SONET/SDH frame.

  2) Encapsulated via Point-to-Point Protocol (PPP) takes place framing information is added with High-level

  Data Link Control (HDLC).

  3) Gaps between frames are filled with flags, set to value 7E.

  4) Octet stuffing occurs if any flags or resultant escape characters (of value 7D) are found in the data.

  5) Data is segmented into an IP datagram with its 20-byte IP header.

  A. 1, 3, 4, 5, 2
  B. 5, 2, 3, 1, 4
  C. 2, 3, 5, 4, 1
  D. 5, 2, 3, 4, 1
  E. 1, 2, 3, 4, 5
  D. 5, 2, 3, 4, 1

• Question 557:

  In an NFV environment, what is the role of an SDN controller?

  C. Dynamically scales up and scales down VM resources
  D. Connects the virtualized networking devices through a common policy-based model
  D. Connects the virtualized networking devices through a common policy-based model

• Question 558:

  

  Refer to the exhibit RIP is used as a PE -CE routing protocol A customer engineer from the remote side notices that the RIP metric changed to an unexpected value Which is the correct configuration that must be applied on PE1 that prevents this behavior?
