A clients network is made up of two network segments, named Subnet A and Subnet B. DHCP clients are located on Subnet A. A DHCP server on Subnet B. You need to make sure that DHCP clients are able to connect to the server. Which of the following actions should you take?

Answer: You should make sure that the DHCP relay agent service is configured.

If the DHCP server is located on a different network segment (subnet) than the clients, these broadcast messages will not traverse routers by default. Therefore, a DHCP relay agent service must be configured on the client's subnet to receive these broadcast requests and forward them as unicast messages to the DHCP server, enabling clients to obtain IP addresses across subnets.

Which of the following is a characteristic of a relational database?

Answer: Data is organized into tables with rows and columns

A relational database is characterized by its structured organization, where data is arranged into two-dimensional tables consisting of rows and columns.
