What is the purpose of a BGP confederation?

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

Which difference must an engineer consider when Implementing Inter-domain and Intra-domain multicast routing on the network?

• Intra-domain routing allows the service provider to control incoming and outgoing multicast data streams on its network, but inter-domain routing limits the service provider's control.
• Intra-domain routing uses the PIM and MBGP protocols for multicast routing, but inter-domain routing must use PIM.SSM or MSDP.
• Intra-domain routing is dependent on the RP router within the same SP network, but inter-domain routing reduces the dependency on the other SP network.
• Inter-domain routing supports policy routing to connect different multicast domains using PIM.SM, but intra-domain routing supports policy routing using PIM-SM only within a single domain.

Which command is used to enable BIDIR-PIM under global configuration mode for Cisco IOS XE Software?

• ip pim bidir ip
• multicast-routing
• ipv4 pim bidir-enable
• Ip pim bidlr-enable

Which statement about BFD on Cisco IOS XR Software is true?

• Cisco IOS XR router must use LDP to route back to the Cisco IOS router to establish the peer relationship.
• Cisco IOS XR Software does not support BFD multihop for IPv4.
• Cisco IOS XR router must use dynamic routing or a static route back to the Cisco IOS router to establish the peer relationship.
• BFD is not compatible between Cisco IOS XR and Cisco IOS Software.

You have configured routing policies on a Cisco IOS XR device with routing policy language. Which two statements about the routing policies are true? (Choose two.)

• The routing policies affect BGP-related routes only.
• If you make edits to an existing routing policy without pasting the full policy into the CLI, the previous policy is overwritten.
• You can change an existing routing policy by editing individual statements.
• The routing policies are implemented in a sequential manner.
• The routing policies are implemented using route maps.

Level 3 switch SW1 is part of an EIGRP enabled network located at the edge of an area. Cisco Express Forwarding and SSO are enabled on the router. A network engineer must minimize the downtime of data-transmit services in the network. HSRP group 2 has already been configured with standby preempt delay minimum 2 and standby timers 140. Which additional action must the engineer take on SW1 to suppress routing flaps for 2 minutes?

• Configure timers standby 2 wait 2 under the HSRP group 2 configuration.
• Configure timers nsf route-hold 120 under the global EIGRP configuration.
• Configure timers nsf signal 2 under the global EIGRP IPv4 address family.
• Configure timers standby 2 coverage 120 under the HSRP group 2 configuration.

What is a requirement of PIM-SM?

• It requires Cisco Express Forwarding to be enabled.
• It must be enabled on loopback interfaces only
• It requires OSPF to be configured on the network.
• It must use an RP

Which feature is used in multicast routing to prevent loops?

• STP
• inverse ARP
• RPF
• split horizon

When deploying a nationwide network of routers, what is the benefit of using BGP confederations?

• availability
• scalability
• security
• automatability

A network engineer is troubleshooting OSPF multiare

• Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?
• hierarchical CLI
• DR support for topology management
• routing process enabled by default on all interfaces
