Which two statements about IPv6 address 2002:ab10:beef::/48 are true?(choose two)

Question:
Which two statements about IPv6 address 2002:ab10:beef::/48 are true?(choose two)

• The embedded IPv4 address can be globally routed.
• It is used for an ISATAP tunnel
• The embedded IPv4 address is an RFC 1918 address
• The MAC address 20:02:b0:10:be:ef is embedded into the IPv6 address
• It is used for a 6to4 tunnel

Explanation: Any IPv6 address that begins with the 2002::/16 prefix is known as a 6to4 address. A 6to4 gateway adds its IPv4 address to this 2002::/16, creating a unique /48 prefix (because an IPv4 consists of 32 bits).

For example: In the IPv6 address 2002:ab10:beef::/48, “ab10:beef” is equivalent to 171.16.190.239 (convert “ab” in hexadecimal to “171” in decimal; “10” in hexadecimal to “16” in decimal…). Therefore the corresponding IPv4 address can be globally routed.
