- B . Manipulate the administration distance of the unicast routes to the two RPs
- C . Manipulate the multicast routing table by creating static mroutes to the two RPs
- D . Advertise the two RP addresses in the routing protocol
- E . Use anycast RP based on MSDP peering between the two RPs

An enterprise plans to evolve from a traditional WAN network to a software-defined WAN network. The existing devices have limited capability when it comes to virtualization. As the migration is carried out, enterprise applications and services must not experience any traffic impact.
Which implementation plan can be used to accommodate this during the migration phase?
- A . Deploy controllers, deploy SD-WAN edge routers. In the data center, and migrate branch sites.
- B . Migrate data center WAN routers, migrate branch sites, and deploy SD-WAN edge routers.
- C . Migrate branch sites, migrate data center WAN routers, and deploy controllers.
- D . Deploy SD-WAN edge routers in the data center, deploy controllers, and migrate branch sites
An enterprise wants to provide low-cost delivery of network systems that can be scaled on business demand, followed by an initiative to reduce capital expenses for new IT equipment.
Which technology meets these goals?
- A . laaS within a private cloud
- B . laaS within an on-premises location
- C . PaaS within a public cloud
- D . SaaS within an on-premises location

While designing a switched topology, in which two options is UplinkFast recommended? (Choose two)

- C . when hello timers are changed to more aggressive values
- D . on access layer switches

- A . EIGRP
- B . IS-IS
- C . OSPF
- D . BGP

- B . Increase the hold queue on the tunnel interface of the spoke routers
- C . Increase the hold queue on the tunnel interface of the hub router
- D . Apply QoS for pak_priority class
- E . Increase the hold queue on the physical interface of the spoke routers.
What is a description of a control plane action?
- A . de-encapsulating and re-encapsulating a packet in a data-link frame
- B . matching the destination MAC address of an Ethernet frame to the MAC address table
- C . matching the destination IP address of an IP packet to the IP routing table
- D . hosts locating routers that reside on attached links using the IPv6 Neighbor Discover Protocol
