Actual exam question for CompTIA's CV0-003 exam

Question #: 86
Topic #: 5

A systems administrator deployed a new web application in a public cloud and would like to test it, but the company's network firewall is only allowing outside connections to the cloud provider network using TCP port 22. While waiting for the network administrator to open the required ports, which of the following actions should the systems administrator take to test the new application? (Select two).

ACreate an IPSec tunnel.

BCreate a VPN tunnel.

COpen a browser using the default gateway IP address.

DOpen a browser using the localhost IP address.

ECreate a GRE tunnel.

FCreate a SSH tunnel.

Show Suggested Answer

Suggested Answer: B, F

To test the new web application in the public cloud, the systems administrator should create a replica database, synchronize the data, and switch to the new instance, and create a SSH tunnel. Creating a replica database can help minimize the downtime and ensure data consistency during the migration. Synchronizing the data can help keep the replica database up to date with the original database. Switching to the new instance can help activate the new web application in the public cloud. Creating a SSH tunnel can help bypass the network firewall and access the web application using TCP port 22. SSH is a secure protocol that can create encrypted tunnels between the local and remote hosts. By creating a SSH tunnel, the systems administrator can forward the web application traffic through the tunnel and test it using a web browser.

Yep, SSH tunnel is the correct answer. I can't believe they even included options like GRE tunnel. What is this, a trick question?

I believe creating an IPSec tunnel could be another viable option to test the new application.

Using the localhost IP address won't work since the application is hosted in the public cloud. I'd go with the SSH tunnel option.

That's a good idea, SSH tunnel should work for testing the application.

I think opening an SSH tunnel would be a great way to test the application while waiting for the network admin to open the ports. It's a secure and reliable option.
