B. VLSM
C. ARP
D. multihoming
A. NAT
Which feature does IPv6 support for securely connecting to networks?
A. NAT
B. VLSM
C. IPsec
D. multihoming
C. IPsec
In which type of IPv6 address does the sender send the traffic to the nearest of multiple nodes, all of which behave in the same way as other nodes that are identified by the same destination address?
A. unicast
B. anycast
C. broadcast
D. multicast
E. loopback
B. anycast
You want to ping the loopback address of your IPv6 local host. Which command will you enter?
A. ping 127.0.0.1
B. ping 0.0.0.0
C. ping ::1
D. ping fe80::1
C. ping ::1
Which two statements describe the characteristics of IPv6 unicast addressing? (Choose two.)
A. Global addresses start with 2000::/3.
B. Link-local addresses start with ff00::/10.
C. Global addresses start with 2000::/.
D. Link-local addresses start with fe00:/12.
G. There is only one loopback address and it is ::1.
A. Global addresses start with 2000::/3.
Which two statements describe the characteristics of IPv6 unicast addressing? (Choose two.)
A. Global addresses start with 2000::/3.
B. Link-local addresses start with ff00::/10.
C. Global addresses start with 2000::/.
D. Link-local addresses start with fe00:/12.
E. There is only one loopback address and it is ::1.
A. Global addresses start with 2000::/3.
E. There is only one loopback address and it is ::1.
Which address bits uniquely identify a group ID in the IPv6 multicast address?
A. first 64 bits
B. first 8 bits
C. last 112 bits
D. last 64
E. last 48
F. last 116 bits
C. last 112 bits
The correct answer is “last 112 bits.” An IPv6 multicast address defines a group of devices known as a multicast group. All IPv6 multicast addresses use the prefix ff00::/8. The 8-bit prefix is followed by 4 bits allocated for flags and a 4-bit scope field, which defines the range to which routers can forward the multicast packet. The remaining 112 bits represent the group ID and identifies the packet destinations. Some common group ID values are ::1, identifying all IPv6 devices within the scope, or ::2, which identifies all IPv6 routers within the scope.
Which new field has a length of 20 bits and is used to mark individual traffic flows with unique values?
A. Flow Label
B. Version
C. Traffic Class
B. Payload Length
A. Flow Label
Which two ICMPv6 types are used for neighbor discovery? (Choose two.)
A. ICMPv6 Type 135
B. ICMPv6 Type 136
C. ICMPv6 Type 129
D. ICMPv6 Type 133
E. ICMPv6 Type 134
A. ICMPv6 Type 135
B. ICMPv6 Type 136
Which protocol in IPv4 performs the same functions as neighbor discovery in IPv6?
A. ARP
B. ICMP
C. DHCP
D. RIP
A. ARP
Which three statements about assigning IPv6 addresses to hosts are accurate? (Choose three.)
A. The entire IPv6 address cannot be manually configured.
B. The host identifier portion of the address cannot be computed automatically.
C. The host identifier portion of the address can be computed automatically using the EUI-64 interface ID.
D. A node on a link can automatically configure its entire global IPv6 address by appending its interface identifier to a prefix that it learns from a router advertisement message.
E. Stateless DHCPv6 keeps a record of which addresses are assigned to which hosts.
F. Stateful DHCPv6 keeps a record of which addresses are assigned to which hosts.
C. The host identifier portion of the address can be computed automatically using the EUI-64 interface ID.
D. A node on a link can automatically configure its entire global IPv6 address by appending its interface identifier to a prefix that it learns from a router advertisement message.
F. Stateful DHCPv6 keeps a record of which addresses are assigned to which hosts.
Which two commands can you use on Cisco network device to test and troubleshoot IPv6 connectivity? (Choose two.)
A. ping
B. traceroute
C. show arp
D. show ip arp
E. arp -a
A. ping
B. traceroute
Which statement is correct about the EUI-64 address format of the interface ID for stateless autoconfiguration that is used by Cisco?
A. It is the MAC address plus the Site-Level Aggregator.
B. It is the MAC address plus the ISO OUI.
C. It expands the 48-bit MAC address to 64 bits by inserting FFFE into the middle 16 bits and then inverting the 7th bit in the first octet.
D. It does not follow IEEE standards for uniqueness of the address.
E. It is only used by Cisco.
C. It expands the 48-bit MAC address to 64 bits by inserting FFFE into the middle 16 bits and then inverting the 7th bit in the first octet.
