ipv6 access-class cisco in

A. all traffic to vty 0 4 from source 2001:DB8:0:4::32

B. only ssh traffic to vty 0 4 from source all

Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a GRE and IPsec tunnel, over the DSL connection, and into the core of an Enterprise network. The branch also allows local hosts to communicate directly with public sites in the Internet over this same DSL connection. Which of the following answers defines how the branch NAT config avoids performing NAT for the Enterprise directed traffic but does perform NAT for the Internet-directed traffic?

A. By not enabling NAT on the IPsec tunnel interface

B. By not enabling NAT on the GRE tunnel interface

C. By configuring the NAT-referenced ACL to not permit the Enterprise traffic

D. By asking the ISP to perform NAT in the cloud

Answer: C

Explanation:

The NAT configuration acts only on packets permitted by a referenced ACL. As a result, the ACL can permit packets destined for the Internet, performing NAT on those packets. The ACL also denies packets going to the Enterprise, meaning that the router does not apply NAT to those packets.

Based on the configuration command below, which statement is true? Router(config)#service timestamps log datetime msec

A. All IOS services will indicate the date and time when the service was started.

B. All syslog messages that are generated will indicate the date and time when the event occurred.

C. All IOS services will indicate the date and time when the service was last used.

D. All high-priority syslog messages that are generated will indicate the date and time when the event occurred.

Question No: 8

For security purposes, an IPv6 traffic filter was configured under various interfaces on the local router. However, shortly after implementing the traffic filter, OSPFv3 neighbor adjacencies were lost. What caused this issue?

A. The traffic filter is blocking all ICMPv6 traffic.

B. The global anycast address must be added to the traffic filter to allow OSPFv3 to work properly.

C. The link-local addresses that were used by OSPFv3 were explicitly denied, which caused the neighbor relationships to fail.

D. IPv6 traffic filtering can be implemented only on SVIs.

Answer: C

What is the benefit of deploying IPv6 in a campus network using dual stack mode?

A. Dual Stack Mode takes advantage of IPv6 over IPv4 tunnel within a network.

B. IPv4 and IPv6 run alongside one another and have no dependency on each other to function

C. IPv4 and IPv6 share network resources.

D. IPv6 can depend on existing IPv4 routing, QoS, security, and multicast policies.

Answer: B

Explanation:

Deploying IPv6 in the campus using the dual-stack model offers several advantages over the hybrid and service block models. The primary advantage of a dual stack model is that it does not require tunneling within the campus network. The dual stack model runs the two protocols as ships in the night, meaning that IPv4 and IPv6 run alongside one another and have no dependency on each other to function except that they share network resources. Both have independent routing.
