  2. You should only use pure Type 2 routes.
  3. You should only use Type 2 and Type 5 routes.
  4. You should only use pure Type 5 routes.
Correct answer: C
Question 2
What is the purpose of the duster-list attribute within a BGP route reflector group?
  1. to disable internal cluster re-advertisements
  2. to define the router that first advertised the route to the route reflector
  3. to override the router 10 value within the cluster
  4. to facilitate loop detection within the route reflector network
Correct answer: D
Question 3
Which two statements about wide and narrow metrics used in IS-IS are correct? (Choose two.)
  1. Wide metrics are sent by default and use 24 bits in TLVs to send information.
  2. Narrow metrics are enabled by default and use 8 bits in TLVs to send information.
  3. Disabling narrow metrics results in external routes being leaked from L1 to L2 areas automatically.
  4. Wide metrics are enabled with the wide-metrics-or.ly parameter under protocols IS-IS hierarchy.
Correct answer: BC
Question 4

Which two statements are correct in this scenario? (Choose two.)
  1. You must establish an IPv6 BGP peering between the two PEs.
  2. You must enable the inet-vpn NLR on both PE devices.
  3. You must enable the inet6-vpn NLRI on both PE devices.
  4. You must enable IPv6 tunneling on the LSPs between the PE devices.

Question 6
The link between CE1 and PE1 has a history of flapping To avoid the impact that flapping causes to the network you decide to use route damping. 
Which statement is correct in this scenario?
  1. Dampened routes decay at a sliding rate known as half-life.
  2. Routes become dampened when the configured max-suppress value is reached.
  3. Dampening is enabled on interfaces.
  4. Dampened routes become active when their figure of merit drops below the reuse value.
Correct answer: A
Question 7
Which two statements regarding Ethernet segments (ES) are correct? (Choose two.)
  1. The Type-1 EVPN route will indicate if the ES is all-active or single-active.
  2. The Type-4 EVPN route will be used to elect the designated forwarder for the ES.
