Your company plans on migrating their network from IPv4 to IPv6 in the near future. Which three techniques can be used to transition from IPv4 to IPv6?()
第1题:
A. 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.
B. IPv6 provides for more host IP addresses but IPv4 provides for more network addresses.
C. Hosts can be configured to receive both IPv4 and IPv6 addresses via DHCP.
D. Host configuration options for IPv4 can be either statically assigned or assigned via DHCP.Host configuration options for IPv6 can be statically assigned only.
E. IPv4 and IPv6 addresses c an be simultaneously assigned to a host but not to a router interface.
第2题:
A. telnet access does not require a password
B. nat
C. no broadcast
D. chanage of destination address in the ipv6 header
E. chanage of source address in the ipv6 header
F. autoconfiguration
第3题:
In IPv6 network, an IPv6 overlay tunnel is required to communicate with isolated IPv6 networks across the existing IPv4 infrastructurE. There are currently fiv e IPv6 overlay tunnel types.Which three IPv6 overlay tunnel statements are true?()
A. Overlay tunnels can only be configured between border routers capable of supporting IPv4 and IPv6.
B. An manual overlay tunnel supports point - to - multipo int tunnels capable of carrying IPv6 and Connectionless Network Service (CLNS) packets.
C. Overlay tunneling encapsulates IPv6 packets in IPv4 packets for delivery across an IPv4 infrastructure.
D. Overlay tunnels can be configured between border route rs or between a border router and a host capable of supporting IPv4 and IPv6.
E. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv4 - compatible, 6to4, and Intra - Site Automatic Tunnel Addressing Protocol (ISATAP) overlay tunneling mechan isms.
F. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv6 - compatible, 4to6, and Multiprotocol Label Switching (MPLS) overlay tunneling mechanisms.
第4题:
A company is using 6to4 tunneling within their IPv6 network. Which two statements about this kindof tunneling are accurate?()
第5题:
A.dual stack
B.dynamic
C.Teredo
D.Manual 6to4
第6题:
A. Dual stack
B. NAT
C. Flow label
D. Mobile IP
E. 6to4 tunneling
F. Anycast
G. MBGP
第7题:
A. statically map IPV4 address to IPV6 addresses
B. configuration IPv4 tunnels between IPV6 islands
C. use DHCPv6 to map IPV4 addresses to IPV6 addresses
D. use proxying and translation to translate IPV6 packets into IPV4 packets
E. configure IPV6 directly
F. enable dual-stack routing
第8题:
A. An automatic 6to4 tunnel does not req uire dual - stack (IPv4 and IPv6) routers at the tunnel endpoints.
B. An automatic 6to4 tunnel allows multiple IPv4 destinations.
C. A manually configured IPv6 in IPv4 tunnel allows multiple IPv4 destinations.
D. A manually configured IPv6 in IPv4 tunnel does not require dual- stack (IPv4 and IPv6) routers at the tunnel endpoints.
第9题:
Which name describes an IPV6 host-enable tunneling technique that uses IPV4 UDP,does not require dedicated gateway tunnels,and can pass through existing IPV4 NAT gateways?()
第10题:
Which two statements are true about using IPv4 and IPv6 simultaneously on a network segment? ()
