Refer to the exhibit. IPv6 must be implemented on R1 to the ISP. The uplink between R1 and the ISP must be configured with a manual assignment, and the LAN interface must be self-provisioned. Both connections must use the applicable IPv6 networks. Which two configurations must be applied to R1? (Choose two.)

  • A. interface Gi0/0
    ipv6 address 2001:db8:0F1B:FCCB:ACCE:FCED:ABCD:FA03:/127
  • B. interface Gi0/0
    ipv6 address 2001:db8:0:AFFF::/64 eui-64
  • C. interface Gi0/1
    ipv6 address 2001:db8:0F1B:FCCB:ACCE:FCED:ABCD:FA02:/127
  • D. interface Gi0/0
    ipv6 address 2001:db8:1:AFFF::/64 eui-64
  • E. interface Gi0/1
    ipv6 address 2001:db8:0F1B:FCCB:ACCE:FCED:ABCD:FA00:/127

The correct configurations to be applied to R1 are: Option B: interface Gi0/0 ipv6 address 2001:db8:0:AFFF::/64 eui-64 This configuration is for the LAN interface (Gi0/0) which is connected to the switch. The IPv6 address is self-provisioned using the EUI-64 method, which is a way of automatically configuring IPv6 addresses on an interface. Option C: interface Gi0/1 ipv6 address 2001:db8:0F1B:FCCB:ACCE:FCED:ABCD:FA02:/127 This configuration is for the WAN interface (Gi0/1) which is connected to the ISP. The IPv6 address is manually assigned as per the requirement. The address falls within the provided WAN network range.

I think wrong 2001:db8:0F1B:FCCB:ACCE:FCED:ABCD:0FA0:/127 its mean 2001:0db8:0f1b:fccb:acce:fced:abcd:0fa0 - 2001:0db8:0f1b:fccb:acce:fced:abcd:0fa1 so the aswer is B,E

What is the range with only 1 bit? Isn't it 0 and 1?

the /127 in ipv6 is the equivalent to /30 in ipv4. the /127 gives only 2 host addresses because an ipv6 address doesn't need a network address for the subnet, and doesn't need broadcast addresses because it uses multicast instead

There is a typo: 2001:0db8:0F1B:FCCB:ACCE:FCED:ABCD:0FA0/127 is the full address It ends with 0FA0 not FA00...B&E are correct but hopefully no typo on exam

BE is correct, thought BC at first but pay attention to the /127 the only available addresses in that range are FA00 and FA01 (works for point to point, and besides FA02 falls outside of that)

I did not understood why it's E at start because i was thinking ok IPv6 we got Hexazecimal so my last Hex can have 15 values 0 - 9 A -F but that would mean 16 bits , in a /127 we only have the last Bit for host portion so it can only be 0 or 1 , that's why A and C are wrong because FA02 and FA03 are not in our range . FA00 FA01 would be in our /127 , we can only have 2 possible host address .
