3. ◉ It is a part of cPanel & WHM. It is meant to install, modify and validate the Apache web server,
PHP and other components of a user.

Easy Apache (EA)

4. ◉ It is one of the release tiers of cPanel & WHM. Rudimentary testing has taken place for versions that are
on this tier. Hence, such versions would be modified further. This tier is not recommended for production
servers.

Whoa! That’s a big number, aren’t you proud?

6. ◉ It is a variant of the Digital Signature Algorithm. Elliptic-curve cryptography (ECC) is used by it.
Equivalent security is provided by ECDSA to RSA keys, using smaller key sizes.
◉ ECDSA provides equivalent security to RSA keys that are using smaller key sizes. Hence, smaller
certificates are generated by ECDSA keys. The result is faster connections and website loading times,
owing to smaller certificates.

Elliptic Curve Digital Signature
Algorithm (ECDSA)

7. ◉ It refers to the ability of a system to deliver email to recipients. It can frequently gauge the success of
email campaigns. It also aids in identifying mail-related DNS problems. A user can view email deliverability
information in the “Email Deliverability” interface in cPanel, by clicking on cPanel -> Home -> Email ->
Email Deliverability.
◉ In the context of Internet, it is imperative to mention websites. The files of websites are stored on the
servers that are provided by web hosting companies. The terms, such as, the “Best Windows Hosting
Company” or “Cloud Hosting Company in India” or even “Website Hosting Companies in India” refer to
web hosting companies.
7
Email Deliverability

8. ◉ It is that stage with regard to the lifecycle of a software, where security updates or bug
fixes are no longer provided by the author.
8
End of Life (EOL)

9. ◉ These are those values that are placed within specific files on the server by advanced
administrators. It is done to change the behavior of PHP,Apache and other systems.

EnvironmentVariables

10. ◉ These are the pages that display warning messages in the scenario where any visitor has
problem while trying to access a user’s site. These pages can be customized in the “Error
Pages” interface in cPanel, by clicking on cPanel -> Home -> Advanced -> Error Pages.
10
Error Pages

11. ◉ It is a free mail transfer agent software which can be configured easily. It is highly flexible. It
can be modified in the “Exim Configuration Manager” interface in WHM, by clicking on
WHM -> Home -> Service Configuration -> Exim Configuration Manager.
11
Exim

12. ◉ It refers to an unstable feature or setting which might cause unintended and unwelcome
consequences. Extreme caution should be exercised if an EXPERIMENTAL feature or
setting is enabled by a user.
◉ These features might not work with other settings or features and are not effective
controls with regard to security.
12
EXPERIMENTAL

13. ◉ It is a filesystem that is journaled and is often used by Linux servers. All cPanel & WHM
installations require ext4.
◉ ext3 filesystem is the predecessor of ext4.
13
Extended Fourth Filesystem (ext4)

14. ◉ It is an Extended Simple Mail Transfer Protocol (ESMTP) command. It is sent by an email
server or client. Its purpose is to identify the email server or client when it establishes a
connection with another email server. The process of sending an email is initiated by this
command, which is followed by the server sending its domain name. The receiving server
or client is notified by the esmtp command that ESMTP extensions are supported by the
sending server.
14
Extended HELO (EHLO)

15. ◉ It is an extension of the original SMTP’s (Simple Mail Transfer Protocol) protocols. An
EHLO request is sent by ESMTP to an email server or client. This is done to identify the
server’s supported protocol. A list of the server’s available ESMTP commands are returned
by it.
15
Extended SMTP (ESMTP)

16. ◉ It refers to a digital certificate for SSL/TLS verification. A comprehensive identity validation
process is used by the certificate authority (CA) to verify the control of the applicant over
the DNS domain. HTTPs are enabled by these certificates on the web browser address bar
of a user. These state the name of the verified owner. The most secure level of domain
validation is offered by these certificates. These certificates can be purchased and installed
in SSL/TLS Wizard interface in cPanel, by clicking on cPanel -> Home -> Security ->
SSL/TLSWizard.
16
ExtendedValidation (EV) Certificate

17. ◉ With the aid of this feature, system administrators are able to grant users access to their
cPanel accounts that are with an external account provider. External Authentication
modules can be used by third-party developers. This authentication can be done through
OpenID Connect-compliant identity providers.
◉ External Authentication can be configured in the “Manage External
Authentications” interface in WHM, by clicking on WHM -> Home -> Security Center ->
Manage External Authentication.
17
External Authentication

18. ◉ It is that method which is used to transfer files from one computer to another. An FTP server that can be
configured by website owners is included in cPanel & WHM.
◉ The user needs to install an FTP client on the local computer. This will ensure that files are send to and
received from the FTP server. An FTP server can be selected in the “FTP Server Selection” interface in
WHM, by clicking on WHM -> Home -> Service Configuration -> FTP Server Selection. It can be
configured in the “FTP Server Configuration” interface in WHM, by clicking on WHM -> Home -> Service
Configuration -> FTP Server Configuration.
◉ A user can create and manage FTP accounts in the “FTP Accounts” interface in cPanel, by clicking on
cPanel -> Home -> Files -> FTP Accounts.
◉ To digress, websites are hosted on the servers that are provided by web hosting companies. These
companies are often known as the “Best Windows Hosting Company” or as “Cloud Hosting Company in
India” or even as “Website Hosting Companies in India”.
18
FileTransfer Protocol (FTP)

19. ◉ It is the system that is used by the operating system in order to manage files and
directories. If multiple partitions are used by a user’s server, then a different filesystem
might be used by each of those partitions.
19
Filesystem

20. ◉ It is that tool in cPanel which processes email based on the user’s preferences. WHM users
can set up many types of filters.
◉ A user can apply filters to a domain’s main email account by using the “Global Email
Filters” interface by clicking on cPanel -> Home -> Email -> Global Email Filters.
◉ Filters can be customized for individual accounts by using the Email Filters interface. The
path for achieving that is, cPanel -> Home -> Email -> Email Filters.
20
Filter

21. ◉ It refers to a security application that is meant to protect servers from attacks initiated by
hackers.
21
Firewall

22. ◉ It is a firewall tool that is meant for Linux operating system. Network and firewall zones
are managed dynamically by it.Additionally, it defines trust levels.
22
Firewalld

23. ◉ It refers to one of the two methods that can be used by a user to restart his/her server.
The server is forced to restart by this method, irrespective of the errors that are
encountered by it.
◉ Its use is recommended only in those situations where a graceful reboot doesn’t work.
That is because it can cause data loss. Both, forceful and graceful reboots can be
performed in theWHM interface.
23
Forceful Reboot

24. ◉ It is a tool that enables a user to forward a copy of every email message that has been
received by him, to some other address. Even if a forwarder is present, the user will still
continue to receive mail at the original recipient address.
◉ In the scenario where a forwarder is created by the user prior to the creation of the
original address, the messages will be forwarded by the system to the end address and not
to the original address as it is not in existence. Forwarders can be created and managed in
the “Forwarders” interface in cPanel, by clicking on cPanel -> Home -> Email ->
Forwarders.
24
Forwarder

25. ◉ It refers to that name which defines the location of a domain in a unique way. It must be
written in lowercase letters.
