Question 1

Refer to the exhibit.

An engineer is comparing two tiles by using the unified cliff format What is determined by the content in the file2.py file?

ALine 16 of file2.py is auth=HTTPBasicAuth(USERNAME. PASSWORD).

BLine 17 of file2.py is auth = HTTPBasicAuth{USERNAME. PASSWORD).

CLine 93 of file2.py is 'DEVICE-STATS'.

DLine 92 of file2.py is 'DEVICE-STATS'.

Answer : C

The unified diff format is used to display differences between two files. The content of the file2.py file shows the added lines in the comparison.

Unified Diff Format: The format uses + to indicate lines added in file2.py and - to indicate lines removed.

Line Addition: Line 93 of file2.py has the 'DEVICE-STATS' line, as indicated by the + symbol in the diff output.

Understanding Unified Diff Format: Unified Diff

Question 2

Which two statements describe the traits of an asynchronous API call? (Choose two.)

AThe order in which API calls return can be guaranteed

BA call to an API does not block the code, but rather it allows application processing to continue

CThe end user can experience latency or performance lag while waiting for the API call to return

DCode execution blocks or waits for the call to an API to return.

EA callback function typically is used to process the response from an API call

Answer : B, E

Asynchronous API calls are non-blocking, meaning the application can continue processing other tasks while waiting for the API call to complete. This helps improve the efficiency and responsiveness of the application. Typically, a callback function is used to handle the response once the API call completes.

Option B is correct because asynchronous API calls do not block the code; they allow the application to perform other operations concurrently.

Option E is correct because a callback function is usually implemented to handle the response of an asynchronous API call once it completes.

Question 3

Which two protocols are associated with the control plane on a network device? (Choose two.)

ABGP

BUDP

CSNMP

DFTP

EOSPF

Answer : A, E

The control plane in a network device is responsible for routing and signaling. Protocols such as BGP (Border Gateway Protocol) and OSPF (Open Shortest Path First) are integral to the control plane.

BGP (Border Gateway Protocol): BGP is used for exchanging routing information between autonomous systems on the internet, making it a crucial control plane protocol.

OSPF (Open Shortest Path First): OSPF is an interior gateway protocol used for routing within an autonomous system, also part of the control plane.

BGP and OSPF Protocol Details: BGP, OSPF

Question 4

Fill in the blanks

Fill in the blanks to complete the Bash script in which each file in a directory is renamed to Its SHA256 hash?

AIsTARGETDIRmv

Answer : A

Check below the answer exact.

Question 5

What is the outcome of executing this command?

git clone ssh://john@exmaple.com/path/to/my-project_git

ACreates a local copy of a repository called ''my project''

BCreates a copy of a branch called ''my project''

CInitiates a new Git repository called ''my project''

DCreates a new branch called ''my project''

Answer : A

When you execute the command git clone ssh://john@example.com/path/to/my-project_git, the git clone command is used to create a local copy of a remote repository. In this case, it is accessing the repository over SSH (Secure Shell). The URL ssh://john@example.com/path/to/my-project_git specifies the location of the remote repository.

git clone is a Git command that creates a copy of an existing repository in a new directory.

The local copy will contain all the history and branches of the original repository.

The repository will be cloned into a directory named after the remote repository, which in this case would be 'my-project'.

Question 6

Which action do webhooks enable an application to perform?

AIncrease the request rate limit.

BPopulate the application with restricted data.

CReceive real-time data.

DImplement a push model.

Answer : C

Simplifying the wording: Webhook enables the app to ( push or receive real time) . The clients Webhooks enable applications to receive real-time data by providing a mechanism for one application to send data to another as soon as an event happens. This is done through HTTP callbacks, where an event in the source system triggers an HTTP POST request to a predefined URL in the destination system. This allows the destination system to process the data immediately, ensuring real-time updates.

Question 7

What is the first development task in test-driven development?

AWrite code that implements a desired function.

BWrite a failing test case for a desired function.

CWrite a passing test case for existing code.

DReverse engineer the code for a desired function.

Answer : B

Test-driven development (TDD) is a software development process where the developer first writes a test for a new function, then writes the code to pass the test, and finally refactors the code. The steps in TDD are:

Write a Failing Test Case: Before any code is written, a test case is created to define the desired functionality.

Write Code to Pass the Test: The minimal amount of code necessary to pass the test is written.

Refactor: The code is refactored for optimization and improvement while ensuring that the tests still pass.
