Question

A server is performing slowly, and users are reporting issues connecting to the application on that server.

Upon investigation, the server administrator notices several unauthorized services running on that server that are successfully communicating to an external site.

Which of the following are MOST likely causing the issue? (Choose two.)

A.

Adware is installed on the users' devices B.

The firewall rule for the server is misconfigured C.

The server is infected with a virus D.

Intrusion detection is enabled on the network E.

Unnecessary services are disabled on the server F.

SELinux is enabled on the server.

AC.

Explanations

A server is performing slowly, and users are reporting issues connecting to the application on that server.

Upon investigation, the server administrator notices several unauthorized services running on that server that are successfully communicating to an external site.

Which of the following are MOST likely causing the issue? (Choose two.)

A.

Adware is installed on the users' devices

B.

The firewall rule for the server is misconfigured

C.

The server is infected with a virus

D.

Intrusion detection is enabled on the network

E.

Unnecessary services are disabled on the server

F.

SELinux is enabled on the server.

AC.

Based on the information provided, two possible causes of the server's slow performance and issues connecting to the application are:

C. The server is infected with a virus Unauthorized services running on the server may indicate that the server has been compromised and infected with a virus. Malware can slow down the server's performance and cause it to behave erratically, including establishing unauthorized communication with external sites.

B. The firewall rule for the server is misconfigured A misconfigured firewall rule can prevent users from accessing the application on the server, or it may allow unauthorized access to the server, including the communication with external sites.

The other options are less likely to be the cause of the issue:

A. Adware is installed on the users' devices Adware is typically not installed on servers, and it would not cause the server to slow down or prevent users from accessing applications.

D. Intrusion detection is enabled on the network Intrusion detection may alert the server administrator to the presence of unauthorized services, but it would not cause the server to slow down or prevent users from accessing applications.

E. Unnecessary services are disabled on the server Disabling unnecessary services may improve server performance, but it would not cause the server to slow down or prevent users from accessing applications.

F. SELinux is enabled on the server. SELinux is a security feature that can help protect the server from unauthorized access, but it would not cause the server to slow down or prevent users from accessing applications.

In conclusion, the most likely causes of the server's slow performance and issues connecting to the application are a virus infection or a misconfigured firewall rule. The server administrator should investigate further to identify and address the root cause of the issue.
