The WannaCry ransomware primarily exploited vulnerabilities in the SMB (Server Message Block) version 1 protocol to propagate across network systems. Microsoft had identified vulnerabilities in SMBv1, which were exploited by the EternalBlue exploit to spread the ransomware. This led to widespread infections, particularly in systems that had not applied the security updates released to patch the vulnerability.References:

Yeah, I was so relieved when I saw that the question appeared in the exam were similar to their exam dumps. It made the exam a lot easier and I felt confident going into it.

Same here. I've heard mixed reviews about using exam dumps, but for us, it definitely paid off.
Stefan
Thank you so much Cramkey I passed my exam today due to your highly up to date dumps.
OceanAug 24, 2025
Agree….Cramkey Dumps are constantly updated based on changes in the exams. They also have a team of experts who regularly review the materials to ensure their accuracy and relevance. This way, you can be sure you're studying the most up-to-date information available.
Cecilia
Yes, I passed my certification exam using Cramkey Dumps.
HelenaAug 15, 2025
Great. Yes they are really effective
Lennox
Something Special that they provide a comprehensive overview of the exam content. They cover all the important topics and concepts, so you can be confident that you are well-prepared for the test.
AizaAug 22, 2025
That makes sense. What makes Cramkey Dumps different from other study materials?
Yusra
I passed my exam. Cramkey Dumps provides detailed explanations for each question and answer, so you can understand the concepts better.

I recently used their dumps for the certification exam I took and I have to say, I was really impressed.
Question 21
A Virtual Private Network (VPN) requires how many Security Associations?
A Virtual Private Network (VPN) typically requires two Security Associations (SAs) for a secure communication session. One SA is used for inbound traffic, and the other for outbound traffic.
In the context of IPsec, which is often used to secure VPN connections, these two SAs facilitate the bidirectional secure exchange of packets in a VPN tunnel.
Each SA uniquely defines how traffic should be securely processed, including the encryption and authentication mechanisms. This ensures that data sent in one directionis handled independently from data sent in the opposite direction, maintaining the integrity and confidentiality of both communication streams.

Question 22
What is the size of the AH in bits with respect to width?
The Authentication Header (AH) in the context of IPsec has a fixed header portion of 24 bits and a mutable part that can vary, but when considering the fixed structure of the AH itself, the width is typically considered to be 32 bits at its core structure for basic operations in providing integrity and authentication, without confidentiality.References:
