Cisco Developing with Cisco Network Programmability Sample Questions:

1. You must document that before your application applies any configuration changes to a device, the application runs those changes through a set of predefined, automated consistency tests called "ACT-CHECK10". The application applies changes only after the test has completed without any ERRORS or WARNINGS.
Which statement about these requirements is true?

A) After applying the configuration changes the user should ping the device to ensure that everything still works.
B) The system should test the configuration before applying it.
C) The system should run consistency checks prior to applying configuration changes.
D) Prior to applying the configuration changes to the device, the system shall run consistency test ACT_CHECK10, and proceed to applying changes only if no errors and/or warnings are reported by the test.
E) The system should call the function app.ACT_CHECK10("config-changes.txt") method and capture the output. The system shall than go through the output to count the number of ERRORS and WARNINGS reported by the test. If the total number of ERRORS and WARNINGS is equal to 0, the system shall proceed to run app.ApplyChanges("config-changes.txt").

2. Which command will provide a similar output to the onep_element_get_property method?

A) show running-configuration

When an application must be developed that interacts with Cisco IOS, NX-OS, and IOS-XR devices, the application must use LDAP for authentication and have secure communication between the Cisco onePK application and managed device. The customer prefers the use of Java for follow-on supportability by their staff. The customer is familiar with the Eclipse IDE. Which application dependency is relevant?

A) use of LDAP for authentication
B) choice of Java as programming language
C) use of secure communication between onePK app and the device

B) to eliminate "dirty bits" from packet headers as they are received by network socket
C) to trigger the "Empty Recycle bin" operation from within a program running on systems that are based on Microsoft Windows
D) to reset memory cells that have failed CRC checks
E) to be used by developers as a tool to clean up the system environment after each test run of the program
