What is the difference between a source tree and a shared tree in a multicast environment?

• To route traffic from source to receiver a source tree uses a link-state routing protocol and a shared tree uses a distance-vector routing protocol.
• A source tree has its root at the source, and a shared tree has its root at a designated rendezvous point.
• To stream multicast from source to receiver, a source tree uses PIM-SM and a shared tree uses PIM-DM.
• Source trees are the default type for bidirectional PIM. and PIM-DM uses shared trees by default.

An ISP has an MPLS VPN-based network with 12 PE routers. How many peerings are required between the 12 routers if the engineer has not configured route reflectors?

• 60
• 66
• 78
• 84

What is used by SR-TE to steer traffic through the network?

• shortest path calculated by IGP
• dynamic rules
• path policy
• explicit maps

An engineer warns to map a multicast IP address to a multicast MAC How many bits are used to make the conversion?

• high-order 24 bits
• higher-order 23 bits
• low order 23 bits
• lower-order 24 bits

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

What Is a characteristic of a segment routing mapping server?

• It must be placed in the core of the network.
• It serves multiple VRFs.
• It must have an IGP adjacency.
• It applies SID mappings from one IGP instance to another IGP instance.

Which output from the show isis interface command helps an engineer troubleshoot an IS-IS adjacency problem on a Cisco IOS-XR platform?

• metric
• priority
• circuit type
• hello interval

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.

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

• availability
• scalability
• security
• automatability

For which reason can two BGP peers fail to establish a neighbor relationship?

• Their BGP send-community strings are misconfigured
• Their BGP timers are mismatched
• Their remote-as numbers are misconfigured
• They are both activated under an IPv4 address family
