Answer:
DHCP Dynamic Host Configuration Protocol:
Is a network service that automatically assigns IP addresses and other TCP/IP configuration information on network nodes configured as DHCP clients. Server allocates IP addresses to DHCP clients dynamically. Should be configured with at least one DHCP scope. Scope contains a range of IP addresses and a subnet mask, and can contain other options, such as a default gateway and Domain Name System. Scope also needs to specify the duration of the lease and usage of an IP affects after which the node needs to renew the lease with the SHCP server. Determines the duration, which can be set for a defined time period or for an unlimited length of time.
DNS Domain Name Service: Is a TCP/IP name resolution service that translates FQDNs into IP addresses. System of hierarchical databases that are stored on separate DNS servers on all networks that connect to the Internet. DNS servers store, maintains and update databases, they respond to DNS client name resolution requests to translate host names into IP addresses.
DNS Components
DNS database is divided logically into a heieratchical grouping of domains. Physically into files called zones. Zone files contain the actual IP-to-host name mapping for one or more domains. Zone files is stored on the DNS server that is responsible for resolving hot names for the domains contained in the zone. Each network node in that domain will have a host record within the domain's zone files. Includes the node's host name, FQDN, and assigned IP address.
DNS Servers
*If you are configuring static IP addresses, including the IP address of the default DNS servers as you configure each client.
*If you are using DHCP, use the DHCP scope options to specify the IP Explanation:

Flex direction
Explanation:
HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.
Generally, all HTML documents are divided into two (2) main parts; body and head.
The head (header) contains information such as version of HTML, title of a page, metadata, link to custom favicons and cascaded style sheet (CSS) etc.
On the other hand, the body of a HTML document contains the contents or informations that a web page displays.
Generally, the part of a HTML document where the cascaded style sheet (CSS) file is linked is the header. 
A style sheet can be linked to an HTML document by three (3) main methods and these are;
I. External style.
II. Inline style.
III. Embedded (internal) style.
Flex direction is a CSS property that's used to determine whether flex items are displayed horizontally or vertically.
