What are two purposes of the BGP scan-time command? (Choose two.)

• A.  to allow faster detection of downed BGP peers
• B.  to improve BGP convergence time
• C.  to tune the BGP process which walks the BGP table and confirms the reachability of next hops
• D.  to tune the BGP update interval

• B.  Rediscover DIS for each link segment.
• C.  Relearn the available IS-IS neighbors.

Which statement is correct regarding the DR election process In this OSPF implementation?

• A.  Both the CE5 and PE6 routers are DROTHERs
• B.  PE6 is the DR for the GigabitEthernet link between PE5 and PE6 because it has a higher OSPF priority
• C.  PE6 is the OSPFv2 and OSPFv3 DR for the GigabitEthernet link between PE5 and PE6
• D.  PE5 is the OSPFv2 DR for the GigabitEthernet link between PE5 and PE6

An engineer is using configuration blocks to build policy-based routing. All other traffic must not be affected and the policy must be applied to GigabitEthernet1/0. Which block correctly implements traffic that is destined for 10.10.10.0/24 using a next hop of 192.168.55.1?

• A.  access-list 110 permit ip any 10.10.10.0 255.255.255.0
  route-map PBR permit 10
  match ip address 110
  set next-hop 192.168.55.1
  interface GigabitEthernet1/0
  ip policy route-map PBR
• B.  access-list 110 permit ip any 10.10.10.0 255.255.255.0
  route-map PBR permit 10
  match ip address 110
  set next-hop 192.168.55.1
  route-map PBR permit 20
  interface GigabitEthernet1/0
  ip policy route-map PBR
• C.  access-list 110 permit ip any 10.10.10.0 0.0.0.255
  route-map PBR permit 10
  match ip address 110
  set next-hop 192.168.55.1
  route-map PBR permit 20
  interface GigabitEthernet1/0
  ip policy route-map PBR
• D.  access-list 110 permit ip any 10.10.10.0 0.0.0.255
  route-map PBR permit 10
  match ip address 110
  set next-hop 192.168.55.1
  interface GigabitEthernet1/0
  ip policy route-map PBR
