Cisco Automating Cisco Data Center Solutions (DCAUTO) Sample Questions:
Question 1
An engineer writes a Python script that uses the `requests` library to call the APIC REST API in a loop with no delay between calls, and after a few hundred iterations the script starts receiving HTTP 403 responses with a "maximum number of user sessions" style error. What is the most likely cause and best remediation?
A. The script's rate of requests exceeds APIC's per-session throughput; remediation is to add
`time.sleep()` after every call
B. The script logs in (POST to `aaaLogin`) on every loop iteration instead of reusing a single authenticated session, exhausting the per-user session limit; remediation is to authenticate once and reuse the session/cookie for all subsequent calls
C. The APIC certificate has expired, causing session invalidation
D. APIC blocks all scripted (non-GUI) access after 403 consecutive requests
Question 2
While working with RESTCONF on an NX-OS device, an engineer sends a GET request to
`/restconf/data/Cisco-IOS-XE-native:native/interface/GigabitEthernet=1` and receives a 404 Not Found, even though the interface exists. What is the most likely cause?
A. RESTCONF is not supported on any Cisco data center platform
B. The interface name must be URL-encoded as `GigabitEthernet%3D1`
C. RESTCONF requires POST instead of GET for read operations
D. The YANG module referenced in the URL belongs to IOS-XE, not NX-OS, so the model/namespace does not exist on this platform
Question 3
A server profile with the string "WEST15" in its name must have the string "WEST15" changed to
"LXT14". For example, server profile "VMHOST-WEST15-01" would need to be changed to
"VMHOST-LXT14-01".
Using the Cisco Intersight REST API in a Python script, which two GET API requests are used to retrieve just the server profile with the string "WEST15" in the name and the correct body for the API request to update the name? Assume the variable "sp_name" contains the name of the retrieved server profile. (Choose two.)
A. GET https://intersight.com/api/v1/server/Profiles?$select=Name&$filter=startswith(Name,
'WEST15')
B. GET https://intersight.com/api/v1/server/Profiles?$select=Name&$filter=Name in('WEST15')
C. GET https://intersight.com/api/v1/server/Profiles?$select=Name&$filter=contains(Name,
'WEST15')
D. BODY = { "Name": sp_name.format('WEST15', 'LXT14') }
E. BODY = { "Name": sp_name.replace('WEST15','LXT14') }
Question 4
What is a feature of model-driven telemetry?
A. continuously streams data out of the network
B. randomizes the data coming to the network
C. continuously pulls data out of the network
D. randomizes the data out of the network
Question 5
Refer to the exhibit. A Python script using ACI Cobra SDK has been constructed.
What is the result when running this script?
A. It prints out the relative name of all application profiles.
B. It prints out the relative name of all tenants.
C. It prints out the distinguished name of all application profiles.
D. It prints out the distinguished name of all tenants.
