A company wants to deploy IPv6 within its existing network infrastructure. All current infrastructure equipment supports IPv6, and the company wants a migration strategy that must not require purchasing additional equipment. The plan must keep operational management costs low, support IPv6 multicast, and allow applications to migrate using DNS. Which strategy must the company choose?
Answer(s): C
Refer to the exhibits. An engineer is troubleshooting an issue in which the Gig0/2 interface on a Cisco switch named SW2 fails to become the root port. Which two commands must be run on SW2 to resolve this issue? (Choose two.)
Answer(s): B,E
Spanning Tree Protocol (STP) Cost:The root port is selected based on the path cost to the root bridge. In this case, Gig0/2 on SW2 is not becoming the root port because its path cost is equal to or higher than the other available interface (Fa0/3). To make Gig0/2 the root port, the path cost on Gig0/2 needs to be adjusted to be lower than the current cost.interface Gig0/2 is necessary to access the interface configuration mode for the Gig0/2 port.spanning-tree cost 5 adjusts the cost of Gig0/2 to a value lower than the current cost of Fa0/3 (cost 4). This ensures Gig0/2 will be preferred as the root port since it has a lower path cost to the root bridge.
Currently, inter-VRF routing between the global routing table and VRF-A is accomplished on the client firewall, but the customer wants to do this on the core network layer. The customer does not want to run BGP, VRF-Lite, or static routing. Which mechanism meets the requirements?
Answer(s): D
The VRF receive feature allows traffic from a specific VRF to be received by interfaces in the global routing table without the need for complex routing protocols such as BGP, VRF-Lite, or static routing. This feature is ideal for enabling inter-VRF routing on the core network layer while meeting the customer's requirements to avoid additional routing configurations. It simplifies inter-VRF communication by associating global routing interfaces with the specific VRF.
An architect is designing a network solution for a customer. The network is IPv6-only with 1000 hosts. The design must provide external access to up to 10 concurrent IPv6 hosts to allow communication with legacy IPv4 devices on an adjacent network. The customer set aside 10 IPv4 addresses to allow for one-to-one communication between hosts. Which solution must the architect select?
Stateful NAT64 is the appropriate solution in an IPv6-only network to allow IPv6 hosts to communicate with IPv4 devices. It provides translation between IPv6 and IPv4 addresses, enabling seamless communication. The "stateful" aspect of NAT64 allows multiple IPv6 hosts to share a limited pool of IPv4 addresses (in this case, 10 IPv4 addresses), which matches the customer's requirement of supporting up to 10 concurrent IPv6 hosts for external communication. This ensures efficient use of the allocated IPv4 addresses while maintaining compatibility with the legacy IPv4 network.
Which feature must be incorporated into the campus LAN design to enable Wake on LAN?
Answer(s): B
