Updated Practice Test Engine and CCNA Security
Hello network engineers! Here it is our first article in our brand new Blog section. We are so excited to start this new adventure. To be honest the moment is a little bit awkward for us because we have to express ourselves in a little bit more informal way, which is something we are not familiar with. Because this is a blog, where we know or at least we hope to meet you more often and to discuss things which are touching our training materials or other interesting topics related to the main topic or our website. We decided to…
New Practice Tests Out!
Life is always full of surprises! Twists, turns, new opportunities. We are taking a deep breath here before writing the rest of the post, because we are very excited! We are thrilled to announce the release of our new practice tests for four certifications of the Associate level of Cisco certifications: CCNA Security, CCNA Wireless, CCNA Cloud and CCDA. This is not the whole thing, we still have more details for you! We believe taking the decision to achieve Cisco certification is a big step in the first place. Cisco certifications come with a bulk of advantages, they both enable…
Ask Me Anything - Discussing Questions From the Tests
We are getting complaints about the questions in our practice tests and this is kind of normal, okay. Recently we got a feedback regarding one particular question and we decided to start this discussion where we are going to analyse those problematic for you questions. We are not going to give you the answers just like that. Instead, we will simulate the case if it is possible or will give you a link to the theory that explains this particular topic. So, let's bite the bullet and here is the first feedback from our visitor: "Really poorly formulated questions. Q:…
Server has a Weak Ephemeral Diffie-Hellman Public Key
Diffie-Hellman key exchange is used to securely exchange cryptographic keys over an insecure public channel. The parties in the exchange choose a private key and come up with a public key. They both share the keys and calculate a shared secret key, which they will use for symmetric key algorithms and secure communications. In the case of a Man-in-the-Middle attack, the attackers can intercept the DH exchange, but they cannot compute the final symmetric keys. With Ephemeral Diffie-Hellman key exchanges, temporary DH secret keys are generated for the connections. Therefore, the same key pairs are never used twice. The Diffie-Hellman…
Windows XP Mode on VMware Player and Windows 8.1
Do you still use Windows XP? What about Windows XP Mode? We are using it a lot for our voice labs when we need to simulate remote branches. In fact, we are using a Windows XP Mode VM with either Cisco IP Communicator or VTGO IP Blue to have additional softphones. Officially, Windows XP died on April 8, 2014, but it is still quite a popular OS, okay? It is actually the third most popular (up-to-date) Windows OS operating system, and it is used by almost 4% of our visitors. I'm saying that because even though we are still using…
