What are two functions of IPv6 Source Guard? (Choose two.)

• A.It works independent from IPv6 neighbor discovery.
• B.It denies traffic from unknown sources or unallocated addresses.
• C.It uses the populated binding table for allowing legitimate traffic.
• D.It denies traffic by inspecting neighbor discovery packets for specific patterns.
• E.It blocks certain traffic by inspecting DHCP packets for specific sources.

Routing protocols are mutually redistributed on R3 and R1. Users report intermittent connectivity to services hosted on the 10.1.1.0/24 prefix. Significant routing update changes are noticed on R3 when the show ip route profile command is run. How must the services be stabilized?

• A.The issue with using BGP must be resolved by using another protocol and redistributing it into EIGRP on R3
• B.The routing loop must be fixed by reducing the admin distance of iBGP from 200 to 100 on R3
• C.The routing loop must be fixed by reducing the admin distance of OSPF from 110 to 80 on R3
• D.The issue with using iBGP must be fixed by running eBGP between R3 and R4

What are two purposes of using IPv4 and VPNv4 address-family configurations in a Layer 3 MPLS VPN?
(Choose two.)

• A.The VPNv4 address is used to advertise the MPLS VPN label.
• B.RD is prepended to the IPv4 route to make it unique.
• C.MP-BGP is used to allow overlapping IPv4 addresses between customers to advertise through the network.
• D.The IPv4 address is needed to tag the MPLS label.
• E.The VPNv4 address consists of a 64-bit route distinguisher that is prepended to the IPv4 prefix.
