The exhibit reveals duplicate IP addresses detected for 10.1.140.6, associated with two different MAC addresses:

88:56:56:ab:c6:89

88:13:30:a3:02:00

Key observations:

Duplicate IP Address Detection:

The message "Duplicate IP address detected for 10.1.140.6" clearly indicates two devices claiming the same IP address.

This typically occurs when one device spoofs the MAC address of another device to intercept or disrupt traffic.

MAC Spoofing Context:

MAC spoofing is a tactic used to impersonate another device's hardware address to gain unauthorized access to a network.

By spoofing a legitimate IP-MAC pairing, an attacker can bypass security mechanisms or cause denial-of-service conditions.

Why the Other Options are Incorrect:

Option B (Mirroring Misconfigured): While mirroring misconfiguration can duplicate traffic, it does not lead to a "duplicate IP detected" alert.

Option C (Misconfigured DHCP): Misconfigurations usually result in DHCP conflicts, but they do not typically involve two different MAC addresses for the same IP.

Option D (ARP Poisoning/MITM): ARP poisoning involves falsified ARP tables, but it does not directly trigger duplicate IP address detection. Instead, ARP packets flood the network.

Conclusion:

The evidence strongly suggests MAC spoofing, as two different MAC addresses are claiming the same IP address (10.1.140.6). This behavior is typical of attempts to gain unauthorized access or disrupt network operations.

ClearPass OnGuard uses a Posture Policy object to define:

Which checks are performed (e.g., AV installed, firewall status, patches)

How the results map to posture tokens such as “Healthy,” “Quarantined,” etc.

The official OnGuard configuration workflow states that you must first “Define the posture policy”, and that these posture policies contain the rules for evaluating health and determining posture tokens.

Service enforcement policies then consume the posture token (e.g., Tips:Posture = Healthy) but do not define the posture conditions themselves. The “Posture” tab on a service is used to enable posture and associate it with the posture policy; the detailed rules live in the posture policy object.

Therefore, posture logic is defined by creating rules within a posture policy → Option A.

In a client-to-site VPN based on tunnel-mode IPsec, the remote clients and a gateway at the main site are responsible for the IPsec encapsulation. The remote clients initiate the VPN connection and encapsulate their traffic in IPsec, which is then decapsulated by the gateway at the main site.

1.IPsec Encapsulation: The remote clients encapsulate their traffic using IPsec protocols before sending it over the internet to the main site.

2.Gateway Role: The gateway at the main site receives the encapsulated traffic, decapsulates it, and forwards it to the internal network. Similarly, traffic from the main site to the remote clients is encapsulated by the gateway and decapsulated by the clients.

3.Security: This setup ensures that data is securely transmitted between the remote clients and the main site, protecting it from eavesdropping and tampering.
