How Routers Handle Packets:

Routers do not change the destination IP address when forwarding packets.

The destination IP remains the same to ensure the packet reaches the intended recipient.

Router’s Role:

Routers inspect the destination IP, determine the best path using routing tables, and forward the packet accordingly.

Conclusion:

The destination IP address remains unchanged; hence, the statement is FALSE.

In STP, a port moves from Learning to Forwarding state after the Forward Delay timer has expired. This delay ensures stability by allowing time for the topology to converge before the port begins forwarding user traffic, thereby preventing loops in the network during the transition​.

Configuration Analysis:

The router has two DHCP pools (pool1 and pool2).

Interface Gi/0/0 is assigned the IP address 10.10.10.1/24 and is configured to use global DHCP.

Reasoning:

The IP address 10.10.10.1 indicates that the interface belongs to the 10.10.10.0/24 network segment.

DHCP assigns IP addresses based on the network of the interface. Therefore, the host will receive an IP address from pool1 (10.10.10.0/24).

A floating static route is configured by assigning a higher preference value to the backup route. This ensures that the backup route (floating route) is used only when the primary route is unavailable. Lower preference values indicate higher priority​.
