Cisco 200-301 - Questions & Answers

By process of elimination, the answer must be B, although I think the PC diagram with the /25 might be confusing some people.
The default route given is 10.10.10.18 for any traffic not matching a known route and the host 10.10.13.10/32 is known, therefore it cannot be A.
It cannot be C because there are no /32, single hosts in the table
It cannot be D because a floating static route is used for higher administrative distances are none are present in this scenario.

Host A address fall within the address range. However, if more than one route to the same subnet exist (router will use the longest stick match, which match more specific route to the subnet). If there are route 10.10.13.192/26 and 10.10.13.208/29, the router will forward the packet to /29 rather than /28.

Spine-leaf architecture is typically deployed as two layers: spines (such as an aggregation layer), and leaves (such as an access layer). Spine-leaf topologies provide high-bandwidth, low-latency, nonblocking server-to-server connectivity. Leaf (aggregation) switches are what provide devices access to the fabric (the network of spine and leaf switches) and are typically deployed at the top of the rack. Generally, devices connect to the leaf switches. Devices can include servers, Layer 4-7 services (firewalls and load balancers), and WAN or Internet routers. Leaf switches do not connect to other leaf switches. In spine-and-leaf architecture, every leaf should connect to every spine in a full mesh.
Spine (aggregation) switches are used to connect to all leaf switches and are typically deployed at the end or middle of the row. Spine switches do not connect to other spine switches.

The hypervisor virtualizes physical components including CPU, memory, and storage. The hypervisor is a software layer that sits between the physical hardware of a computer and the operating system. It virtualizes physical components such as CPU, memory, and storage, allowing for multiple operating systems to run on a single physical machine. This allows for improved scalability, flexibility, and resource utilization.

The command "ipv6 address 2001:DB8:5:112::/64 eui-64" automatically generates an IPv6 address from a specified IPv6 prefix and MAC address of an interface using the EUI-64 method. The EUI-64 method uses the MAC address of the interface to create an interface identifier (IID) that is used to complete the IPv6 address.

Option A ("ipv6 address dhcp") configures an interface to obtain an IPv6 address through DHCPv6.

Option C ("ipv6 address autoconfig") configures an interface to automatically obtain an IPv6 address using Stateless Address Autoconfiguration (SLAAC).

Option D ("ipv6 address 2001:DB8:5:112::2/64 link-local") configures an IPv6 link-local address on the
interface.

The EUI-64 method uses the MAC (Media Access Control) address of the network interface to generate a unique 64-bit identifier. The MAC address is a unique identifier assigned to the network interface by the manufacturer and is usually 48 bits long. The EUI-64 method takes the MAC address and adds a 16-bit value to create a 64-bit identifier.

If the destination MAC address is not in the CAM table (unknown destination MAC address), the switch sends the frame out all other ports that are in the same VLAN as the received frame. This is called flooding. It does not flood the frame out the same port on which the frame was received.
