Which two options are benefits of EIGRP OTP? (Choose two.)

• A. It fully supports multicast traffic.
  
  
• B. It allows EIGRP routers to peer across a service provider without the service provider involvement.
  
  
• C. It requires only minimal support from the service provider.
  
  
• D. It allows the customer EIGRP domain to remain contiguous.
  
  
• E. It allows the administrator to use different autonomous system numbers per EIGRP domain.
  
  
• F. It allows EIGRP neighbors to be discovered dynamically.
  

Which two statements about redistribution are true? (Choose two.)

• A. When OSPF traffic is redistributed into BGP, internal and external routes are redistributed.
  
  
• B. When BGP traffic is redistributed into OSPF, the metric is set to 1 unless the metric is defined.
  
  
• C. When EIGRP routes on a CE are redistributed through a PE into BGP, the Cost Community POI is set automatically.
  
  
• D. iBGP routes automatically redistribute into the IGP if the routes are in the routing table.
  
  
• E. When BGP traffic is redistributed into OSPF, eBGP and iBGP routes are advertised.
  
  
• F. When EIGRP traffic is redistributed into BGP, a default metric is required.
  

Which option is an incorrect design consideration when deploying OSPF areas?

• A. area 1 - area 0 - MPLS VPN backbone - area 0 - area 2
  
  
• B. area 1 - MPLS VPN backbone - area2
  
  
• C. area 1 - MPLS VPN backbone - area 1
  
  
• D. area 2 - area 0 - MPLS VPN backbone - area 1
  
  
• E. area 0- area 2 - MPLS VPN superbackbone - area 1
  

Which two statements about RIPng are true? (Choose two.)

• A. Both inbound and outbound route filtering can be implemented on a single interface.
  
  
• B. A route with a metric of 15 is advertised as unreachable.
  
  
• C. RIPng can support as many as 8 equal-cost routes.
  
  
• D. 16 is the maximum metric it can advertise.
  
  
• E. RIPng can support as many as 32 equal-cost routes
  

When is it useful to disable split horizon on an EIGRP interface?

• A. Disable it when you want to send routes that are learned from another routing protocol to peer on the same interface.
  
  
• B. Disable it when you want to provide additional backup paths in your network.
  
  
• C. It is never advisable to disable split horizon on an EIGRP interface.
  
  
• D. Disable it when you need to send updates to peers on the interface on which the updates were received.
  

What are two mechanisms that directed ARP uses to help resolve IP addresses to hardware addresses? (Choose two.)

• A. It uses ICMP redirects to advertise next-hop addresses to foreign hosts.
  
  
• B. It removes address-resolution restrictions, allowing dynamic protocols to advertise routing information for the device loopback address.
  
  
• C. It uses a proxy mechanism to allow a device to respond to ARP requests for the addresses of other devices.
  
  
• D. It removes address-resolution restrictions, allowing dynamic protocols to advertise routing information for the next-hop address.
  
  
• E. It uses a series of ICMP echo messages to relay next-hop addresses.
