What is the primary difference between dynamic NAT and PAT?

Dynamic NAT requires static mappings; PAT uses dynamic mappings

Dynamic NAT uses a pool of public addresses; PAT uses a single address with unique port numbers

Dynamic NAT is used for inbound traffic; PAT is used for outbound traffic

Dynamic NAT maps multiple inside addresses to a single outside address; PAT maps one-to-one

What is the purpose of VRRP priority?

To determine which router becomes the master

To set the authentication method

To control the interval of VRRP advertisements

To define the virtual IP address

In PIM Sparse Mode, what is the role of the Rendezvous Point (RP)?

It is the root of the shared tree for a multicast group

It is the backup for the multicast source

It is the last-hop router for receivers

It is the source of the multicast traffic

A network engineer configures an NTP client on a router. The client receives time from a server with stratum 3. What does the stratum value indicate?

The number of NTP hops between the client and the server

The authentication key used for NTP packets

The accuracy level of the server's time source relative to the reference clock

A network engineer is troubleshooting multicast forwarding on a router. The router is receiving multicast packets on an interface, but it is not forwarding them. The engineer suspects that the Reverse Path Forwarding (RPF) check is failing. What should the engineer verify?

That the outgoing interface list is not empty.

That the multicast group address is in the multicast routing table.

That the unicast route to the multicast source is reachable via the interface that received the multicast packet.

That the multicast source address is in the multicast routing table.
