QUESTION NO: 1
Which three route filtering statements are true? (Choose three)
A.After the router rip and passive-interface s0/0 commands have been issued, the s0/0 interface will not send any RIP updates, but will receive routing updates on that interface.
B.After the router eigrp 10 and passive-interface s0/0 commands have been issued, the s0/0 interface will not send any EIGRP updates, but will receive routing updates on that interface.
C.After the router ospf 10 and passive-interface s0/0 commands have been issued , the s0/0 interface will not send any OSPF updates, but will receive routing updates on that interface.
D.When you use the passive-interface command with RIPv2, multicasts are sent out the specified interface
E.When you use the passive-interface command with EIGRP, hello messages are not sent out the specified interface.

Section 4 – Implement an IPv6 based solution, given a network design and a set of requirements

QUESTION NO: 1
Which two statements are true about using IPv4 and IPv6 simultaneously on a network segment? (Choose two.)
A. Hosts can be configured to receive both IPv4 and IPv6 addresses via DHCP.
B. Host configuration options for IPv4 can be either statically assigned or assigned via DHCP.
Host configuration options for IPv6 can be statically assigned only.
C. IPv6 allows a host to create its own IPv6 address that will allow it to communicate to other devices on a network configured via DHCP. IPv4 does not provide a similar capability for hosts.
D. IPv4 and IPv6 addresses can be simultaneously assigned to a host but not to a router interface. E. IPv6 provides for more host IP addresses but IPv4 provides for more network addresses.
