An enterprise network uses ISATAP to provide IPv6 connectivity to hosts. A host is unable to obtain an IPv6 address via ISATAP. The ISATAP router is configured correctly, and the host's IPv4 address is 192.168.1.10. What is the most likely reason the host is not getting an ISATAP address?

The host's firewall is blocking ISATAP traffic

The host's IPv4 address is not in the same subnet as the ISATAP router

The host does not have IPv6 enabled

The ISATAP router is not advertising a prefix

In ISATAP tunneling, where is the IPv4 address of the tunnel endpoint embedded?

In the last 32 bits of the interface identifier

In the first 32 bits of the IPv6 address

In the first 16 bits of the interface identifier

In an IPv6 over IPv4 tunnel, what happens to the IPv6 packet at the tunnel destination?

It is decapsulated by removing the IPv4 header and then routed as an IPv6 packet

It is discarded and the IPv4 packet is forwarded instead

It is re-encapsulated with a new IPv6 header before being forwarded

It is translated into an IPv4 packet and forwarded to the final destination

Part of the IPv6 domain, which makes up ~5% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~2–3 in this domain), expect 1–1 from this objective — we provide 16 practice questions to prepare you well beyond it.

A company wants to enable IPv6 connectivity for Windows hosts on an IPv4-only enterprise network. The hosts have no native IPv6 connectivity, and the administrator does not want to configure each host manually. The network uses a single site with no requirement for inter-site tunneling. Which tunneling mechanism is most appropriate?
