Technical Terms - Hardware (A-Z) - Zone File

What is a zone file?

• A file stored on a database server containing information about the domains within that database server's zone

• A file stored on a web server containing information about the domains within that web server's zone

• A file stored on a name server containing information about the domains within that name server's zone

• A file stored on a mail server containing information about the domains within that mail server's zone

What is included in a zone file?

• Contact information about the database server's administrator and IP addresses of databases

• Contact information about the name server's administrator and IP addresses of domains

• Contact information about the web server's administrator and IP addresses of websites

• Contact information about the domain owner and IP addresses of subdomains

What is the purpose of a Start of Authority (SOA) record in a zone file?

• Lists the email address of the name server's administrator and settings for refreshing the zone file

• Lists the email address of the domain owner and settings for refreshing the subdomain file

• Lists the email address of the web server's administrator and settings for refreshing the website file

• Lists the email address of the database server's administrator and settings for refreshing the database file

What do DNS records in a zone file match?

• Match a specific subdomain name with the corresponding server's IP address

• Match a specific domain name with the corresponding server's email address

• Match a specific subdomain name with the corresponding server's email address

• Match a specific domain name with the corresponding server's IP address

What do directives in a zone file specify?

• Instructions for the database server to follow, like specifying a TTL expiration timer or an origin domain

• Instructions for the web server to follow, like specifying a TTL expiration timer or an origin domain

• Instructions for the domain owner to follow, like specifying a TTL expiration timer or an origin domain

• Instructions for the name server to follow, like specifying a TTL expiration timer or an origin domain

What is the purpose of zone files in the Domain Name System (DNS) infrastructure?

• Allow computers to locate servers on the Extranet at all levels of the DNS system hierarchy

• Allow computers to locate servers on the Intranet at all levels of the DNS system hierarchy

• Allow computers to locate servers on the Darknet at all levels of the DNS system hierarchy

• Allow computers to locate servers on the Internet at all levels of the DNS system hierarchy

How are zones subdivided in the DNS system?

• Into smaller zones, which may be subdivided into even smaller zones

• Into larger zones, which may be subdivided into even larger zones

• Into equal-sized zones, which may be subdivided into different-sized zones

• Into irregular zones, which may be subdivided into regular zones

What is the largest zone in the DNS system?

• Cover the entirety of each second-level domain (like example.com and test.net)

• Cover the entirety of each top-level domain (like .com and .net)

• Cover the entirety of each third-level domain (like mail.example.com and www.test.net)

• Cover the entirety of each fourth-level domain (like smtp.mail.example.com and blog.www.test.net)

What happens when another computer on the Internet makes a request to a name server?

• The name server checks the zone file and returns the requested domain's physical address

• The name server checks the zone file and returns the requested domain's website address

• The name server checks the zone file and returns the requested domain's email address

• The name server checks the zone file and returns the requested domain's IP address

What is the role of a name server in the DNS system?

• Maintains a zone file for the domains within its zone and the corresponding IP address for each domain and subdomain

• Maintains a zone file for the domains within its zone and the corresponding website address for each domain and subdomain

• Maintains a zone file for the domains within its zone and the corresponding physical address for each domain and subdomain

• Maintains a zone file for the domains within its zone and the corresponding email address for each domain and subdomain
