CCNP Enterprise 350-401 Syllabus Exam Questions Answers

A next-generation firewall protects against more than basic IP, port, and protocol violations. Its key value is application visibility and control. In a data center, an NGFW can identify applications regardless of port, inspect application behavior, enforce policy based on application identity, and block malicious or risky applications that traditional firewalls may allow if they use permitted ports such as TCP 80 or 443. Therefore, option D is the best answer. DDoS protection is usually handled by dedicated DDoS mitigation systems, upstream scrubbing services, rate limiting, or cloud-based DDoS protection rather than being the defining function of a data center NGFW. Unauthorized analyzers and rogue APs are not the primary threat categories addressed by a data center NGFW; rogue AP detection is more aligned with wireless security and WIPS/WIDS. The key ENCOR concept is that NGFWs add application awareness, user/context-based policy, intrusion prevention, malware inspection, and advanced threat defense to traditional stateful firewalling.

The correct answer is B. to connect wired endpoints to the SD-Access fabric.

In Cisco SD-Access, the fabric edge node is the device that provides access for endpoints into the fabric. It is the point where user devices such as PCs, phones, printers, and access points attach to the SD-Access network. The edge node handles endpoint onboarding into the fabric and applies the appropriate segmentation and policy.

A fabric edge node is specifically responsible for:

Connecting wired endpoints to the fabric

Serving as the access-layer entry point into the SD-Access fabric

Enforcing policy and segmentation for connected endpoints

Extending the fabric to end hosts

This is the main role of the edge node in the SD-Access architecture.

A. to connect the fusion router to the SD-Access fabric This is not the role of the fabric edge node. The fusion router is used outside the fabric to provide connectivity between the fabric and external networks.

C. to advertise fabric IP address space to external networks This function is associated with the border node, not the edge node. The border node connects the fabric to external domains and exchanges reachability information.

D. to connect external Layer 3 networks to the SD-Access fabric This is also the function of the border node, not the edge node.

Remember these SD-Access node roles clearly:

Edge node = connects endpoints

Border node = connects to external networks

Control-plane node = maintains endpoint-to-location mappings

Fusion router = external routing/services outside the fabric

Edge node = endpoint access into the fabric

The correct snippet is option B because json.dump(Devices, OutFile) serializes the Python data structure and writes the resulting JSON directly to the open file object. The file is opened in write mode with open( " devices.json " , " w " ), and OutFile.close() closes the file after writing. Option A is wrong because json.load() reads JSON from a file and converts it into a Python object; it does not write a Python object to disk. It is also being used on a file opened in write mode, which is logically incorrect. Option C writes str(Devices), which produces a Python string representation of the dictionary, not standards-compliant JSON. That output may use single quotes and Python-specific formatting, which is not proper JSON. Option D uses json.dumps(Devices), which returns a JSON-formatted string, but it does not write that string to the file because the return value is ignored. ENCOR automation questions often test the difference between dump, dumps, load, and loads.
