Refer to the exhibit. You are planning a migration to a dual-stack IPv4/1Pv6 campus environment while providing a flexible and scalable design with fault isolation. The design should allow IPv6 devices to tunnel over portions of the campus that are not yet natively IPv6-enabled, including wireless and voice endpoints. Your plan requires an interim approach that allows for a faster introduction of new services without requiring a network wide hot cutover. Which two services block functions meet these requirements? (Choose 2)

Question

Accepted Answer

A. IPv6 ISATAP tunnel termination point An ISATAP tunnel termination point allows IPv6 hosts to use the existing IPv4 infrastructure as a virtual IPv6 link layer, enabling endpoints such as wireless and voice devices to reach IPv6 services even where the campus fabric is not yet natively dual-stacked. C. GRE tunnel to the local Internet edge A GRE tunnel to the Internet edge encapsulates IPv6 packets inside IPv4 headers, allowing IPv6 traffic to transit IPv4-only campus segments and reach external IPv6 destinations without requiring a simultaneous network-wide upgrade.

Answer

B. policy gateways Policy gateways enforce traffic policies and QoS but provide no tunneling or encapsulation mechanism to carry IPv6 over IPv4-only network segments.

Answer

D. BGP route reflectors BGP route reflectors address BGP session scalability within an AS and do not provide any IPv6-over-IPv4 tunneling capability for endpoints.

Answer

E. GET VPN key server GET VPN is a group-based encryption framework for WAN traffic and has no role in tunneling IPv6 packets over non-IPv6 campus infrastructure.
