A Junos device has a routing table with multiple routes, but the forwarding table is missing a route that exists in the routing table. What is the most likely reason for this discrepancy?

The route is a static route with a next hop that is unreachable.

The route is hidden because it failed validation checks.

The route is not active because it is not the best route for the prefix.

The route is a discard route and does not need a forwarding entry.

When multiple equal-cost paths exist to the same destination, what does Junos do by default?

It load-balances traffic across the equal-cost paths.

It selects the path with the lowest IP address.

It randomly selects one path for all traffic.

It uses only the first path and ignores the others.

A Junos router has a route with a next hop of 192.0.2.1. The ARP table shows no entry for 192.0.2.1. What will the router do when forwarding a packet using this route?

It will forward the packet to the default gateway instead.

It will use the MAC address of the outgoing interface.

It will drop the packet because the next hop is unreachable.

It will send an ARP request to resolve the next-hop MAC address.

A Junos router is experiencing high CPU usage on the Routing Engine. Which type of traffic is most likely to cause this?

Traffic that is destined to the router itself, such as management or routing protocol traffic.

Traffic that requires a route lookup in the forwarding table.

Traffic that is forwarded normally by the PFE.

Traffic that is load-balanced across multiple paths.
