• Question 262:

  Refer to the exhibit.

  

  A customer has two eBGP internet links: one primary high-speed (10 Mbps) and one backup low-speed (1 Mbps). The requirement is to use the 10M link (ISP 1) for all inbound/outbound traffic and only use the 1M link (ISP 2) during failure. What is the correct BGP-based design solution?

  A. Advertise a higher local preference to ISP 2. Increase the AS PATH inbound from ISP 1
  B. Advertise a longer AS PATH to ISP 2. Increase the MED to ISP 2
  C. Advertise more specific routes to ISP 1. Increase the local preference attribute of inbound BGP from ISP1
  D. Advertise less specific routes to ISP 2. Increase the AS PATH inbound from ISP 1
  B. Advertise a longer AS PATH to ISP 2. Increase the MED to ISP 2

• Question 263:

  A. BFD control packets are sent at a slower pace because the echo function is enabled
  B. BFD echo packets are sent from forwarding engines along the Layer 2 path to perform detection
  C. BFD control packets are sent at a higher pace because the echo function is enabted
  D. Only BFD control packets are sent from forwarding engines along the Layer 2 path to perform detection
  E. DUMPS BFD sessions at either end actively participate in the forwarding of echo packets
  B. BFD echo packets are sent from forwarding engines along the Layer 2 path to perform detection
