QuestionQ3

Network Element Programmability

Refer to the exhibit below.

Question Image

Assuming a new ACI instance, what occurs when this script runs?

  • A Ten objects are created and subsequently deleted.
  • B Nine objects are created.
  • C An exception is thrown.
  • D Ten objects are created.
Explanation

range(1,10) produces the nine values 1 through 9. The script submits one tenant-creation request for each value, creating nine uniquely named tenant objects; it does not contain any operation that deletes them.

Operations

A file named myfunc.py has been edited. Place the steps in the correct sequence to commit this file to the local Git repository and then confirm its status. Not every option is used.

Drag & Drop

git add
git status
git commit -m "new function"
git commit -msg "new function"
step 1
step 2
step 3
Explanation

git add . stages the changed file(s), git commit -m "new function" records the staged changes in the local repository, and git status reports the resulting working-tree and staging status. The -m option is the correct commit-message flag.
