Refer to the exhibit. The extension header of the IPv6 header is ignored when which value is equal to zero?

• A. Segments Left
• B. Hdr Ext Len
• C. Next Header
• D. Routing Type

Refer to the exhibit. A network engineer is installing two new routers to connect a small company's headquarters via router R1 and a branch office via R2. The engineer configured OSPF on both routers using process ID 1 for consistency. R1 has been designated as an ABR for Area 0 and Area 1, and R2 is located in Area 0. After completing the initial configuration and bringing up the two devices, the engineer noticed that the ABR at headquarters is failing to advertise routes to the branch office within Area 0. Which additional action must the engineer take on R1 to resolve the issue?

• A. Configure the area 1 range 10.0.0.0 0.0.0.255 command under the OSPF process.
• B. Configure the summary-address 10.0.0.0 0.0.0.255 area 0 command under the OSPF process.
• C. Configure the network 10.0.1.0 0.0.0.255 area 0 command.
• D. Configure the router ospf 1 area 1 network 10.0.1.0 0.0.0.255 command.

What is the difference between RPL and route map actions?

• A. RPL uses pass, set, and drop actions only, and route maps use match, set, and drop actions.
• B. RPL uses match, set, drop, and stop actions, and route maps use match, set, and drop actions
• C. RPL uses pass, set, drop, and done actions, and route maps use match and set actions only.
• D. RPL uses match, pass, set, and drop actions, and route maps use match, set, and drop actions.

Refer to the exhibit. A network engineer must enable segment routing between the three autonomous systems with these requirements:
- OSPF link-state data for area 0 routers must be distributed to the
controller via BGP LS.
- EPE must be enabled on the egress node in AS 100.
- Routers must advertise peer node SIDs to the controller R1 via BGP
LS.
Which configuration must the engineer apply?

• A. R1(config)# router ospf 100
  R1(config-ospf}# distribute link-state instance-id 100 throttle 10
  R1(config)# router bgp 100
  R1(config-bgp}# neighbor 10.10.10.1
  R1(config-bgp-nbr)# remote-as 200
  R1(config-bgp-nbr}# egress-engineering
  R1(config-bgp}# neighbor 192.168.30.1
  R1(config-bgp-nbr}# remote-as 100
  R1(config-bgp-nbr}# address-family link-state link-state
• B. R2(config)# router ospf 100
  R2(config-ospf)# redistribute bgp 100
  R2(config)# router bgp 100
  R2(config-bgp}# neighbor 192.168.20.1
  R2(config-bgp-nbr)# remote-as 100
  R2(config-bgp-nbr}# egress-engineering
  R2(config-bgp}# neighbor 10.10.10.1
  R2(config-bgp-nbr}# remote-as 200
  R2(config-bgp-nbr}# address-family link-state link-state
• C. R1(config)# router ospf 100
  R1(config-ospf)# redistribute bgp 100
  R1(config)# router bgp 100
  R1(config-bgp}# neighbor 192.168.30.1
  R1(config-bgp-nbr)# remote-as 100
  R1(config-bgp-nbr}# egress-engineering
  R1(config-bgp}# neighbor 10.10.10.1
  R1(config-bgp-nbr}# remote-as 200
  R1(config-bgp-nbr}# address-family link-state link-state
• D. R2(config)# router ospf 100
  R2(config-ospf}# distribute link-state instance-id 100 throttle 10
  R2(config)# router bgp 100
  R2(config-bgp}# neighbor 10.10.20.1
  R2(config-bgp-nbr)# remote-as 300
  R2(config-bgp-nbr}# egress-engineering
  R2(config-bgp}# neighbor 192.168.20.1
  R2(config-bgp-nbr}# remote-as 100
  R2(config-bgp-nbr}# address-family link-state link-state

Refer to the exhibit. Multicast traffic destined from T1 and T2 routers to RP routers works well. A network engineer observes problems with multicast traffic flows between Site-A and Site-B. Site- A users fail to receive multicast stream on Site-B via RPTV site, while Site-B users fail to receive multicast stream on Site-A via RPTZ site. Which action must be implemented to resolve the issues?

• A. Establish MDSP peering with interface IP subnet.
• B. Configure direct OSPF peering between Site-A and Site-B.
• C. Allow the OSPF and MSDP packets on the firewall.
• D. Configure Site-A and Site-B in 10.80.148./24 subnet.
