What is the role of segment routing mapping server?

It advertises a local SID mapping policy to all the mapping clients.

It works with IGP instances to calculate the prefix-SIDs in the absence of a mapping policy.

It selects multiple mapping entries to create overlapping active mapping policies.

It reads and translates remotely received SIDs from other mapping servers to create SID mapping entries.

Which difference should be considered when intradomain or interdomain multicast routing is implemented?

A network uses intradomain multicast routing without interdomain routing but networks that use interdomain multicast routing must also apply intradomain routing

Interdomain multicast routing requires an IS-IS or OSPF neighbor relationship between the domains but intradomain multicast routing requires only BGP

Interdomain multicast routing relies on PIM-DM and intradomain multicast routing relies on PIMSM.

interdomain multicast routing uses BIDR-PIM to establish neighbor relationships between AS and interdomain multicast routing uses MSDP

A network uses intradomain multicast routing without interdomain routing but networks that use interdomain multicast routing must also apply intradomain routing

Which difference must an engineer consider when choosing whether to implement OSPF or IS-IS as the routing protocol on the network?

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

A source tree has its root at the source, and a shared tree has its root at a designated rendezvous point.

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.
