6V0-21.25 Exam Dumps : VMware vDefend Security for VCF 5.x Administrator

VMware vDefend Distributed Malware Prevention is a highly comprehensive feature set that operates at the hypervisor level (via Guest Introspection).

Detection and Prevention: It can be configured in "Detect Only" mode for visibility, but it fully supports "Prevention" mode to actively block malicious file writes/transfers.

OS Support: Because it leverages a thin agent/introspection architecture, it provides native support for protecting both Windows and Linux virtual machines.

NDR Integration: Every time the Malware Prevention engine detects a suspicious file, extracts a hash, or performs local static analysis, it automatically forwards this threat event telemetry up to the Network Detection and Response (NDR) engine for cross-correlation.

Therefore, "All of the above" accurately describes its capabilities.

=========================

When automating VMware vDefend (NSX) using REST APIs, actions are mapped to standard CRUD (Create, Read, Update, Delete) operations using HTTP verbs. When an administrator needs to Update an existing security policy, object, or group, they must use either PUT or PATCH.

PUT: This is a "replace" operation. When you send a PUT request to a specific object's URI, you must include the entire configuration payload for that object. It overwrites the existing configuration completely.

PATCH: This is a "partial modify" operation. If you only want to change a single parameter (like changing a firewall rule action from "ALLOW" to "DROP") without re-sending the entire rule configuration, you use PATCH.

(Note: POST is strictly for Create, GET is for Read, and DELETE is for Delete).

=========================

This statement is True . In any production environment, certain legitimate administrative tools can mimic attacker behavior. For example, your internal security team's vulnerability scanner (like Nessus or Qualys) will constantly perform horizontal and vertical port scans across the network. If NTA monitored these scanners, it would trigger thousands of false-positive alerts. VMware vDefend allows administrators to selectively exclude specific VMs, IP addresses, or groups from specific NTA detectors, ensuring the AI engine only flags genuine anomalous threats and reducing alert fatigue for security operators.
