Netskope NSK300 Exam With Confidence Using Practice Dumps

When Netskope performs SSL inspection on traffic that uses certificates issued by an internal Certificate Authority (CA) not trusted by Netskope, the platform generates an SSL error and blocks the connection. To resolve this for internal sites using private CA certificates, three approaches are valid: bypassing SSL inspection for the affected sites using a Do Not Decrypt rule removes the certificate validation issue by passing traffic through without inspection; changing the SSL Error Settings in the Netskope UI from Block to Bypass for the self-signed or untrusted certificate error type allows the traffic to flow even when Netskope cannot validate the certificate chain; and importing the internal root CA certificate into Netskope’s trusted certificate store enables full chain validation for all sites using that CA. Creating a Real-time Protection policy to allow access or instructing users to click through errors are not effective or scalable enterprise solutions.

A host mismatch SSL error occurs when the hostname in the server’s certificate does not match the hostname the client is requesting. When Netskope performs SSL inspection and substitutes its own certificate, if the trusted partner’s application uses a certificate with a Common Name or SAN that differs from the URL being accessed, Netskope will flag this as a host mismatch and block the connection. Two valid solutions exist: first, creating an SSL Decrypt rule to bypass inspection for that specific destination, which allows the original certificate to be presented end-to-end without Netskope substitution; second, configuring the Netskope tenant to bypass Host MisMatch errors under the SSL Error Settings, which instructs Netskope to allow connections with hostname mismatches rather than blocking them for that error type.

Netskope provides two built-in mechanisms to monitor the health of IPsec and GRE tunnels configured in the platform. Layer 4 health checks use TCP or UDP probes to verify end-to-end connectivity and reachability through the tunnel, providing active validation that the data path is functional. Dead Peer Detection (DPD) is an IKEv2 protocol mechanism that periodically confirms that the remote peer is still reachable and responsive; if the peer fails to respond, the tunnel is considered down and a re-establishment attempt is initiated automatically. ICMP keepalive probing is not a Netskope-native tunnel health monitoring feature, and the Netskope Trust Portal provides platform-wide service availability status rather than individual tenant-specific tunnel health monitoring.
