Question#1

Which authorization framework gives third-party applications limited access to HTTP services?

A. IPsec
B. GRE
C. Basic Auth
D. OAuth 2.0

Question#2

Refer to the exhibit.



Which Python snippet stores the data structure of the device in JSON format?

A. A close up of a text AI-generated content may be incorrect.
B. A close up of a logo AI-generated content may be incorrect.
C. A close up of a text AI-generated content may be incorrect.
D. A black text on a white background AI-generated content may be incorrect.

Question#3

Which protocol is implemented to establish secure control plane adjacencies between Cisco Catalyst SD-WAN nodes?

A. IPsec
B. TLS
C. IKE
D. ESP

Explanation:
The correct answer is B. TLS.
Key Concept (Cisco SD-WAN Control Plane Security):
In Cisco Catalyst SD-WAN, the architecture separates:
Control Plane → Secure communication between controllers and edge devices
Data Plane → Encrypted tunnels carrying user traffic
Why B is correct:
The control plane (between vSmart, vBond, vManage, and WAN Edge routers) uses:
TLS (Transport Layer Security)
In some cases also DTLS, depending on configuration
These protocols provide:
Authentication
Encryption
Integrity protection
Thus, TLS is used to establish secure control plane adjacencies.
Why the other options are incorrect:
A. IPsec
Used for data plane encryption (IPsec tunnels), not control plane.
C. IKE
Used for key exchange in IPsec, not for SD-WAN control plane adjacencies.
D. ESP
Part of IPsec (data plane encryption), not control plane.
Final ENCOR Exam Tip:
Memorize this SD-WAN separation:
Control Plane → TLS /DTLS
Data Plane → IPsec (ESP encapsulation)
This distinction is frequently tested in ENCOR exams.

Question#4

Refer to the exhibit.



POSTMAN is showing an attempt to retrieve network device information from Cisco Catalyst Center (formerly DNA Center) API.
What is the issue?

A. The token has expired
B. The URI string is incorrect
C. Authentication has failed
D. The JSON payload contains the incorrect UUID

Question#5

Which AP mode allows a supported AP to function like a WLAN client would, associating and identifying client connectivity issues?

A. SE-connect mode
B. sensor mode
C. client mode
D. sniffer mode
