Technical Support Test

A client has a high-traffic website that is currently hosted on a single server. To ensure high availability and to distribute the load across multiple servers, they have decided to implement a load balancing solution.

The client has set up two additional servers identical to the original one, and all three servers are configured to serve the website. They have also set up a load balancer and updated their DNS records so that the website's domain now points to the load balancer.

Now, the client approaches you to verify the configuration. While reviewing the setup, you discover that the client hasn't configured session persistence (also known as sticky sessions) on their load balancer.

Which of the following are potential issues the client might face due to the lack of session persistence?

A: Users may experience slower website load times.
B: User sessions might be lost, causing them to be logged out unexpectedly.
C: The load balancer may not distribute traffic evenly across the servers.
D: The website may not be accessible if one of the servers goes down.
E: Users may not be able to establish a secure connection to the website.

You are a technical support specialist and a client contacts you reporting they are unable to access their website after changing their domain's DNS records to point to a new web host. They receive an error message stating the server's IP address could not be found.

Upon investigation, you determine that:

1. The client made the DNS changes 24 hours ago.
2. The client's device is unable to resolve the domain to the new IP address.
3. Other devices in the client's local network also can't access the website.
4. The client is able to access other websites without issues.
5. Using an external tool, you find that DNS propagation has completed in most parts of the world.

Given these facts, what should the client do to resolve the issue?

A: Wait for another 24 hours for DNS propagation to complete.
B: Update the domain's DNS records again.
C: Reset the router and clear the DNS cache on their devices.
D: Contact the new web host and ask them to check their server configuration.
E: Change the domain's DNS records to point to the old web host.

A client's Linux server has been experiencing brute force attacks on their SSH service. To reduce the risk of successful attacks, the client wants to change the default SSH port from 22 to a non-standard port.

The client updates the /etc/ssh/sshd_config file on the server and changes the line `#Port 22` to `Port 2222`. They then save and close the file.

What should the client do next to apply the changes and start using the new SSH port?

A: Restart the network service using the command `service network restart`.
B: Reboot the entire server using the command `reboot`.
C: There's no need to do anything; the changes will take effect immediately.
D: Run the command `ssh -p 2222` to start using the new port.
E: Restart the SSH service using the command `service sshd restart`.

As a technical support specialist, a client approaches you with a concern that their website's load time is considerably slow. They mention that their users are reporting load times of up to 20 seconds. They request your help in troubleshooting the issue.

You perform the following steps to investigate:

1. You access the website from your location and it loads within 3 seconds.
2. You use a web performance testing tool that tests the website from various locations globally and the average load time reported is 5 seconds.
3. You review the website's code and find it to be optimized with no obvious performance issues.
4. The client's website is hosted on a server located in London.

Given this information, which of the following is most likely causing the slow load times reported by the users?

A: The website is experiencing high traffic volumes.
B: The server needs to be upgraded to a more powerful one.
C: The users are located far from the server location.
D: The website's code is inefficient and needs to be optimized.
E: The server's network connection is unreliable.

Emily has a good professional relationship with Rebecca, who sent the email. Rebecca has a question, which she needs an urgent response to. Answering the question in detail will require Emily to access a number of files in her own office. What should Emily do first?

A: Reply immediately that she needs more information before she can respond in detail, and that she will do it first thing on Monday morning.

B: Rebecca will have gotten an out of office (OOO) response, so she can leave it for now and respond first thing on Monday morning.
