Which two conditions must be met before separate ISPs can provide interdomain multicast routing? (Choose two.)

• A.Each ISP must support intradomain multicast routing.
• B.Each ISP must configure MSDP to connect its individual multicast administrative domain to the domains at other ISPs.
• C.Each ISP must configure its network to use PIM-DM.
• D.Each ISP must replace its RP assignment with a global RP.
• E.Each ISP must dedicate a single router to handle multicast traffic between providers.

What is the purpose of a BGP confederation?

• A.It reduces the number of iBGP peers and increases stability.
• B.It limits the number of routes a device receives from its peers, which reduces CPU load.
• C.It improves service by increasing the number of simultaneous iBGP peering sessions.
• D.It redirects traffic away from route reflectors, which reduces their operating load.

Refer to the exhibit. Router 1 resides in a different data center than Router 2 and Router 3.
Router 1 is running the IS-IS routing protocol, and it is preconfigured with LDP and segment routing. Which configuration must the engineer apply under router isis 111 on Router 1 to implement TI-LFA on the link to Router 2 without disrupting traffic to Router 3?

• A.interface GigabitEthernet0/0/1
  address-family ipv4 unicast
  fast-reroute per-prefix
  fast-reroute per-prefix ti-lfa
• B.interface GigabitEthernet0/0/1
  address-family ipv4 unicast
  fast-reroute per-prefix
• C.interface GigabitEthernet0/0/1
  fast-reroute per-prefix ti-lfa enable
• D.interface GigabitEthernet0/0/1
  fast-reroute prefix enable

Refer to the exhibit. Company X is multihomed to a service provider. With the default settings, the link between PE2 and CE1 is the primary link, but company X has asked for the link between PE4 and CE2 to operate as the primary instead. A network engineer used a route map with local- preference to manipulate the routes from PE2 to CE1 to be less desirable and applied the route map on PE2 outbound to CE1. However, the path from PE2 to CE1 is still preferred.
Which action must the engineer take so that the desired path is chosen?

• A.Apply local-preference on PE2 outbound to CE2 with a value less than 100.
• B.Apply MED in the outbound direction on PE2 to CE1 with a cost lower than the path from PE4 to CE2.
• C.Configure the AS path prepend attribute to increase the number of hops between CE2 and PE4.
• D.Configure the weight attribute on PE2 in the outbound direction to CE2 with a value less than
  65535.

Refer to the exhibit. OSPF is configured in the network. The company operates several business units in a single building. To bring in a new business unit, which is located on a different floor from the others, a network engineer recently added area 2 to the network. To allow hosts connected to R5 to reach servers connected to R6, the engineer manipulated the OSPF path so that traffic from R6 traverses the link from R2 to R4 to reach R5. However, when the engineer ran a connectivity test between the host and server, it failed. Which action must the engineer take to resolve the issue?

• A.Extend area 0 to area 2 using a virtual link.
• B.Change area 2 to a stub area.
• C.Redistribute OSPF area 1 routes into area 2 on R3 and R4
• D.Configure a sham link between R6 and R2 to create a point-to-point link through the OSPF backbone.
