+Deberás poder instalar y configurar un servidor web. Configurar un servidor web para proporcionar HTTPS e instalar y configurar un servidor proxy, incluidas las políticas de acceso, la autenticación y el uso de recursos. Por último, deberás poder instalar y configurar un servidor proxy inverso, Nginx. Se incluye la configuración básica de Nginx como servidor HTTP.

+===== Recomendaciones =====
+De cara al examen, habría que tener claro:
+  * Configuración un servidor Apache básico.
+  * Conocer las principales directivas de Apache.
+  * Configuración hosts virtuales.
+  * Configuración la autentificación de usuarios.
+  * Conocer los conceptos de certificados digitales.
+  * Configurar un sitio web seguro con SSL.
+  * Configuración básica del servidor proxy squid.
+  * Configuración un servidor web Nginx.
+  * Configuración un proxy reverso con Nginx.
+===== Tests =====
+**There is a restricted area in an Apache site, which requires users to authenticate against the file /srv/www/security/site-passwd. Which command is used to CHANGE the password of existing users, without losing data, when Basic authentication is being used.**
+  * ''htpasswd -c /srv/www/security/site-passwd user''
+  * ''htpasswd /srv/www/security/site-passwd user''  (**Solución**)
+  * ''htpasswd -n /srv/www/security/site-passwd user''
+  * ''htpasswd -D /srv/www/security/site-passwd user''
+  * None of the above.
+Con la primera opción estaríamos creando el fichero de nuevo, cargándonos el existente.
+**When Apache is configured to use name-based virtual hosts:**
+  * it's also necessary to configure a different IP address for each virtual host.
+  * The Listen directive is ignored by the server.
+  * it starts multiple daemons (one for each virtual host).
+  * it's also necessary to create a VirtualHost block for the main host. (**Solución**)
+  * only the directives ServerName and DocumentRoot may be used inside a block
+**Which of the following lines in the Apache configuration file would allow only clients with a valid certificate to access the website?**
+  * SSLCA conf/ca.crt
+  * AuthType ssl
+  * IfModule libexec/ssl.c

+  * In a SSLHost directive
+**Which of the following is recommended to reduce Squid's consumption of disk resources?**
+  * Disable the use of access lists.
+  * Reduce the size of cache_dir in the configuration file. (**Solución**)

+  * Disable logging of fully qualified domain names.
+  * Reduce the number of child processes to be started in the configuration file.
+**Which ACL type in Squid's configuration file is used for authentication purposes?**
+  * proxyAuth

+}
+</code>
+  * ''remote_proxy''
+  * ''reverse_proxy''
+  * ''proxy_reverse''
+  * ''proxy_pass'' (**Solución**)
