In the exhibit, OSPF routers R1, R2, R3, and R4 come up, in order, at 1-minute intervals
Which router will be the designated router?.

You have been asked to configure an IPv6 address for a group of interfaces that could belong on
different routers. If a packet is sent to that address, it should be received by all routers in the
group.
Which address type would be suited for these requirements?

What is the function of the hop limit field in the IPv6 header?

You have been asked to define a default gateway for traffic leaving a router. This route should use
interface so-0/0/0 as its next-hop. Which type of route would be suited for this scenario?

In the exhibit, how many full OSPF adjacencies will R3 have?

You are asked to design a Layer 2 switched topology that can automatically recover from link
failures.
Which type of protocol would you consider in your design?

When the Junos configuration shown in the exhibit is applied to the router, which routes in the
forwarding table will begin load-balancing packet flows?

You have configured MPLS and RSVP in your network using all of the Junos defaults. You
established an LSP in your network which is reporting an up status but no traffic is using it.
Which two statements reflect potential causes for this issue? (Choose two)

Using industry best practices, what is true regarding an external BGP session?

You own a home network connecting through an always-on connection and need to assign IPv6
addresses to your routers because you want to follow the guidelines spelled out in RFC 3177. You
want to design your network with the correct prefixes.
Which prefix would your ISP likely allocate to your network?
