• Question 3:

  A Tier 2 ISP provides Internet connectivity to residential and business customers. The Tier 2 ISP uses Internet transit service from multiple Tier 1 ISPs at different locations. Lately, the link utilization on a few links to Tier 1 ISPs has increased to unacceptable levels while other links have low link utilizations. Which two methods can alleviate this issue without deploying additional links? (Choose two.)

  A. Use the BGP AS prepend feature to influence how Internet traffic enters from Tier 1 ISPs.
  B. Use the BGP MED attribute to influence how Internet traffic exits towards Tier 1 ISPs.
  C. Use the BGP Local Preference to influence how Internet traffic exits towards Tier 1 ISPs.
  D. Change the IGP cost metrics in the core.
  E. Use QoS to rate-limit traffic.
  A. Use the BGP AS prepend feature to influence how Internet traffic enters from Tier 1 ISPs.
  C. Use the BGP Local Preference to influence how Internet traffic exits towards Tier 1 ISPs.

• Question 7:

  

  Refer to the exhibit. Two customer sites are connected via an MPLS Layer 3 VPNv4 network. OSPF is used as a PE-CE routing protocol. EIGRP is used in the internal LAN that connects the CE02. CE01 cannot reach any host connected in this LAN. Which configuration must be applied to fix this issue?

  A. CE2# router ospf 65000 address-family ipv4 vrf VPN_A redistribute eigrp 65000 match internal external 1 external 2
  B. PE2# router bgp 100 address-family ipv4 vrf VPN_A redistribute eigrp 6500 vrf VPN_A
  C. PE2# router bgp 100 address-family ipv4 vrf VPN_A redistribute connected
  D. PE2# router bgp 100 address-family ipv4 vrf VPN_A redistribute ospf 100 vrf VPN_A match internal external 1 external 2
  A. CE2# router ospf 65000 address-family ipv4 vrf VPN_A redistribute eigrp 65000 match internal external 1 external 2

• Question 8:

  

  Refer to the exhibit. A customer has two sites connected to an MPLS Layer 3 VPN Backbone. OSPF is the PE-CE protocol. A backdoor link exists between these two sites and it must be used only as a backup connection. An operation engineer observed that the PE9 prefers CE-43 path to reach 2001:db8:59::/64 prefix instead of via PE8 path. Which solution the engineer must implement to ensure that the PE9 prefers the PE8 to reach 2001:db8:59::/64 prefix?

  A. Implement a hub-and-spoke topology with PE8 as the hub site and PE9 as a spoke site.
  B. PE9 must apply an OSPF down bit when it learns prefixes from CE-43.
  C. Increase the BGP local preference value on PE8 to be higher than PE9.
  D. PE8 must remove the OSPF down bit when it learns prefixes from CE-37.
  E. Establish sham-link between PE8 and PE9.
  E. Establish sham-link between PE8 and PE9.

• Question 9:

  B. partial route computation
  C. incremental SPF calculations
  D. SPF prefix prioritization
