QUESTION 49
Refer to the exhibit.

A network engineer must configure new interfaces on a set of devices and is planning to use an Ansible playbook for the task. All devices support SSH and NETCONF protocol, and the interface variables are unique per device. In which directory are the YAML files including variables hosted to automate the task with the netconf_config module?

current working directory

host_vars directory

group_vars directory

home directory

In Ansible, when using the netconf_config module to automate configuration tasks that include unique interface variables for each device, the variables should be defined in individual YAML files within the host_vars directory. This directory contains host-specific variable files named after each host, allowing Ansible to load the appropriate variables for each device during playbook execution.

QUESTION 50
A customer’s cloud services must:
Migrate services to another data center on demand.
Save the operational state of the machine on demand.
Support Windows and Linux GUIs.
Maximize hardware utilization.
Which type of deployment meets these requirements?

bare metal

container

virtual machine

Kubernetes

Virtual machines (VMs) provide the flexibility and capabilities required to meet the described requirements.
VMs can easily migrate between data centers, save and restore their state, and support various operating systems and GUIs.
* Migration: VMs can be moved from one physical server or data center to another, providing high flexibility in resource management.
* State Saving: VMs support saving the operational state (snapshots), allowing quick recovery or migration.
* Support for GUIs: VMs can run different operating systems, including those with graphical user interfaces (GUIs) like Windows and Linux.
* Hardware Utilization: VMs enable better utilization of hardware resources by running multiple VMs on a single physical host.

QUESTION 52
How does requesting a synchronous API operation differ from requesting an asynchronous API operation?

clients poll for the status of the execution of operations

clients subscribe to a webhook for operation results

clients can access the results immediately

clients receive responses with a task id for further processing

* Synchronous API Operations:
* Immediate Response: In a synchronous operation, the client sends a request to the server and waits for an immediate response. The client cannot proceed until it receives this response.
* Blocking Call: The call is considered blocking, meaning the client application is blocked from performing other tasks until the response is received.
* Use Case: This is useful when the result of the operation is required immediately to continue the workflow.
* Asynchronous API Operations:
* Delayed Response: In an asynchronous operation, the client sends a request to the server and does not wait for an immediate response. Instead, it continues its processing and can check back later for the result.
* Non-blocking Call: The call is non-blocking, allowing the client to perform other tasks while waiting for the server to complete the operation.
* Polling and Webhooks: Clients may poll the server for status updates or subscribe to a webhook to be notified when the operation is complete.
* Task ID: The server may provide a task ID in the response that can be used to check the status of the operation later.

QUESTION 53
What is a functionality of the Waterfall method as compared to the Agile method for software development?

Waterfall increases agility to implement faster while Agile promotes reliability.

A phase begins after the previous phase has ended in Waterfall while Agile phases run in parallel.

Customers get feedback during the process in Waterfall while they can see the result at the end in Agile.

Requirements can be updated in Waterfall while in Agile it should be gathered in the beginning.

The Waterfall method is a sequential software development process where a phase begins only after the previous phase has ended. In contrast, Agile development involves iterative processes where phases run in parallel and are continuously improved upon.
A . Waterfall increases agility to implement faster while Agile promotes reliability – Incorrect. This is the opposite of the typical characteristics of these methods. B. A phase begins after the previous phase has ended in Waterfall while Agile phases run in parallel – Correct. Waterfall is linear and sequential, while Agile is iterative and parallel. C. Customers get feedback during the process in Waterfall while they can see the result at the end in Agile – Incorrect. Agile involves continuous feedback, whereas Waterfall typically provides feedback only at the end. D. Requirements can be updated in Waterfall while in Agile it should be gathered in the beginning – Incorrect. Requirements in Agile can be updated continuously, while Waterfall requires requirements to be defined upfront.

QUESTION 55
What is the purpose of a MAC address?

To uniquely identify a router in a LAN

To uniquely identify a network interface in a LAN

To uniquely identify a device on the internet

To uniquely identify a switch in a LAN

A MAC (Media Access Control) address is a unique identifier assigned to a network interface card (NIC) for communications at the data link layer of a network segment. MAC addresses are used within local area networks (LANs) to ensure that data packets are delivered to the correct hardware device. Every network interface on a device, such as a computer, router, or switch, has a unique MAC address.

configure a device with native and OpenConfig-based models

send CLI commands to a device and retrieve output in JSON format

run Linux commands natively on the device

bootstrap a device that has a factory-default configuration

Anyone can create YANG data models. In most cases, they are created by network equipment vendors, the IETF, and OpenConfig.

QUESTION 62
Which REST architectural constraint indicates that no client context should be stored on the server between requests?

stateless

uniform interface

cacheable

client-server

In REST architecture, the stateless constraint indicates that no client context should be stored on the server between requests. Each request from the client to the server must contain all the information needed to understand and process the request.
Stateless: Ensures that each request is independent and contains all necessary information.
Uniform interface: Defines a standard way of interacting with resources.
Cacheable: Responses must define whether they are cacheable to improve performance.
Client-server: Separates the client and server roles.

QUESTION 63
Which HTTP status code means that the server cannot or will not process the request because of a perceived client error?

100

203

303

400

QUESTION 64
Refer to the exhibit.

A developer cannot reach the web application behind an NGINX load balancer. The developer sends a request to an application FQDN with cURL but gets an HTTP 502 response. Which action solves the problem?

Fix errors in the server configuration, which is behind the load balancer.

Bring up the load balancer to the active state.

Fix errors in the cURL request sent by the client.

Change the default gateway on the load balancer to an active one.

Explanation
The HyperText Transfer Protocol (HTTP) 502 Bad Gateway server error response code indicates that the server, while acting as a gateway or proxy, received an invalid response from the upstream server.
