"Users in your office are complaining that they cannot connect to the servers" at a remote site. When troubleshooting, you find that you can successfully reach the servers from router R2. What is the most likely reason that the other users are experiencing connection failure?

VLSM is missconfigured between the router interface and the DHCP Pool

Explanation:

Variable-Length Subnet Masking (VLSM) can also be called "subnetting subnets, an it implies that network engineers are given the opportunity to be able to produce various sizes of IP address by dividing the IP address space into hierarchical subnets with the aim of creating subnets with relatively distinct host counts that avoids using too many addresses. The benefits of VLSM are that it brings about a more efficient network addressing, and it also allows network engineers to do route summarization.

A router refers to networking device which enables the sending of data packets among computer networks. It is also used to send data packets from VLSM to DHCP pool.

he Dynamic Host Configuration Protocol (DHCP) Pool refers to a built-in server employed in networks by Virtual Controller to assign IP address to clients. A simultaneous access to many clients can be achieved by customizing the DHCP Pool as it can accommodate about 2048 addresses.  

Whenever there the VLSM is missconfigured between the router interface and the DHCP Pool, some users under a different router will not be to connect to the servers while users using another router will be able to connect.

loool i m also trying to figure that out.seems like u should have genius ranking
