DAD. SYN flooding.
A SYN flooding attack is a type of Denial of Service attack that exhausts a server’s resources by sending a large number of TCP SYN requests without completing the TCP three way handshake. The server allocates resources for each half open connection and waits for the final ACK that never arrives. As these half open connections accumulate, the server’s connection table becomes full, preventing legitimate users from establishing new connections and making the service unavailable.
Why The Other Options Are Incorrect
A. IP spoofing
IP spoofing involves forging the source IP address in packets to disguise the sender’s identity or impersonate another system. While it may be used as part of other attacks, by itself it does not directly exhaust server resources.
B. TCP hijacking
TCP hijacking occurs when an attacker takes control of an existing TCP session between two systems. This attack targets confidentiality and session control rather than overwhelming a server’s resources.
C. Port redirection
Port redirection forwards traffic from one port to another system or service. It is typically used for pivoting during penetration testing and does not cause resource exhaustion on a server.

GUWhat is High Availability (HA) in Firewalls?
HA allows two firewalls to work together so that if one fails, the other automatically takes over without disrupting network security or connectivity.
• What Firewall HA is
• Active-Passive vs Active-Active
• Why HA is critical in enterprise networks
• How organizations avoid downtime
Perfect for CCNA, CCNP, Network Security, and Firewall learners.

DAB. SNMP v1. SNMPv1 is a legacy protocol that uses plaintext community strings for authentication. These community strings function essentially like passwords but are transmitted without encryption, making them easy to capture through packet sniffing. Because of this weakness, SNMPv1 is considered insecure and is commonly disabled during hardening. Modern deployments use SNMPv3, which supports authentication and encryption. Since the analyst is already disabling legacy protocols, SNMPv1 is the next protocol that should be blocked.
Why The Other Options Are Incorrect
A. LDAPS v3
LDAPS (LDAP over SSL/TLS) is a secure protocol used for encrypted directory authentication and queries. It protects credentials during transmission and is widely used in secure enterprise environments such as Active Directory integrations. Blocking it would remove a secure service rather than eliminate a legacy risk.
C. TLS 1.3
TLS 1.3 is the most modern and secure version of the TLS protocol currently in widespread use. It improves security by removing weak cryptographic algorithms and simplifying the handshake process. Disabling TLS 1.3 would weaken security rather than strengthen it.
D. Kerberos v5
Kerberos v5 is a secure authentication protocol commonly used in enterprise environments, especially in Active Directory. It provides mutual authentication and ticket based access control. It is not considered a legacy insecure protocol and should remain enabled.

TESubnetting finally made sense when I saw it like this…
(And it took me way too long)
If IP addresses and subnetting ever felt confusing — you’re not alone.
Let’s break it down in the simplest way possible 👇
Imagine this:
You’re managing a company with 4 different offices
But you only have ONE network:
👉 192.168.1.0/24
Now the problem:
How do you divide this network so each office runs smoothly without conflicts?
💡 Here’s where subnetting changes everything
Instead of one big messy network, we split it into 4 clean subnets (/26 each):
🔹 Office 1 → 192.168.1.0/26
🔹 Office 2 → 192.168.1.64/26
🔹 Office 3 → 192.168.1.128/26
🔹 Office 4 → 192.168.1.192/26
Now each office gets:
✔️ Its own IP range
✔️ Its own broadcast address
✔️ A clean, isolated network
🎯 What this actually improves:
• No IP conflicts
• Better performance
• Easier troubleshooting
• Stronger security
💭 And the best part?
Once this clicks… networking starts to feel EASY.
📌 If you're learning networking or preparing for CCNA, this is a must-know concept.

PM5 Things about IPsec VPN which every Network Engineers must Know.
1️⃣ IPSec provides Encryption so attackers cannot read data.
2️⃣ It ensures Integrity so packets cannot be modified.
3️⃣ It provides Authentication to verify the peer device.
4️⃣ It creates a secure tunnel between two networks.
5️⃣ IPSec is commonly used for Site-to-Site VPN and Remote Access VPN.
