IPv6 Questions



Here you will find answer to IPv6 Questions
Question 1
Which of these statements best describes the major difference between an IPv4-compatible tunnel and a 6to4 tunnel?
A. An IPv4-compatible tunnel is a static tunnel, but an 6to4 tunnel is a semiautomatic tunnel.
B. The deployment of a IPv4-compatible tunnel requires a special code on the edge routers, but a 6to4 tunnel does not require any special code.
C. An IPv4-compatible tunnel is typically used only between two IPv6 domains, but a 6to4 tunnel is used to connect two or more IPv6 domains.
D. For an IPv4-compatible tunnel, the ISP assigns only IPv4 addresses for each domain, but for a 6to4 tunnel, the ISP assigns only IPv6 addresses for each domain.

Answer: C
Question 2
Which IPv6 address would you ping to determine if OSPFv3 is able to send and receive unicast packets across a link?
A. anycast address
B. site-local multicast
C. global address of the link
D. unique local address
E. link-local address

Answer: E
Question 3
You are using IPv6, and would like to configure EIGRPv3. Which three of these correctly describe how you can perform this configuration? (Choose three)
A. EIGRP for IPv6 is directly configured on the interfaces over which it runs.
B. EIGRP for IPv6 is not configured on the interfaces over which it runs, but if a user uses passive-interface configuration, EIGRP for IPv6 needs to be configured on the interface that is made passive.
C. There is a network statement configuration in EIGRP for IPv6, the same as for IPv4.
D. There is no network statement configuration in EIGRP for IPv6.
E. When a user uses a passive-interface configuration, EIGRP for IPv6 does not need to be configured on the interface that is made passive.
F. When a user uses a non-passive-interface configuration, EIGRP for IPv6 does not need to be configured on the interface that is made passive

Answer: A D E
Question 4
Which of these statements accurately identifies how Unicast Reverse Path Forwarding can be employed to prevent the use of malformed or forged IP sources addresses?
A.    It is applied only on the input interface of a router.
B.    If is applied only on the output interface of a router.
C.    It can be configured either on the input or output interface of a router.
D.    It cannot be configured on a router interface.
E.    It is configured under any routing protocol process.

Answer: A
Question 5
Unicast Reverse Path Forwarding can perform all of these actions except which one?
A. examine all packets received to make sure that the source addresses and source interfaces appear in the routing table and match the interfaces where the packets were received 
B. check to see if any packet received at a router interface arrives on the best return path
C. combine with a configured ACL
D. log its events, if you specify the logging options for the ACL entries used by the unicast rpf command
E. inspect IP packets encapsulated in tunnels, such as GRE

Answer: E
Question 6
During the IPv6 address resolution, a node sends a neighbor solicitation message in order to discover which of these?
A. The Layer 2 multicast address of the destination node
B. The solicited node multicast address of the destination node
C. The Layer 2 address of the destination node based on the destination IPv6 address
D. The IPv6 address of the destination node based on the destination Layer 2 address

Answer: C
Question 7
When using IP SLA FTP operation, which two FTP modes are supported? (Choose two)
A. Only the FTP PUT operation type is supported.
B. Active mode is supported.
C. Passive FTP transfer modes are supported.
D. FTP URL specified for the FTP GET operation is not supported.

Answer: B C
