Refer to the exhibit. Which snippet of code must be added to enable the API to manage users in Cisco Unified CM?

Question

Options

• Aurl = 'https://<ip address>:8443/axl/' username = 'admin' password = 'password'
• Burl = 'https://<ip address>:8443/axl/' axl_version = '12.5'
• Curl = 'https://<ip address>:8443/axl/' cert_file = 'cert.pem' key_file = 'key.pem'
• Durl = 'https://<ip address>:8443/axl/' axl_version = '12.5' username = 'admin' password = 'password'

• A
  15% (7)
• B
  7% (3)
• C
  4% (2)
• D
  74% (34)

Explanation

Option D is correct because the Cisco AXL (Administrative XML) API requires three essential components to function: the endpoint URL, the AXL schema version (axl_version), and authentication credentials (username/password) - all of which D provides together.

Why the distractors fail:

• A omits axl_version, which the AXL client needs to load the correct WSDL schema; without it, the API cannot serialize/deserialize requests properly.
• B omits username and password, so the HTTPS request will fail authentication - Cisco UCM's AXL API requires Basic Auth credentials.
• C replaces credentials with certificate files (cert.pem/key_file), which is not the standard authentication method for AXL over Basic Auth, and also omits axl_version.

Memory tip: Think of AXL as needing three things to "AVP" - Address (URL), Version (axl_version), and Password + username. Any answer missing one of these three legs is incomplete.
