Question # 11

A development team uses Kubernetes for application development. Any changes on ConfigMap are performed manually for each development, test, and production environment. The edits are performed to deploy applications. This approach causes inconsistent deployments across all environments.

Which practice improves the consistency of the deployments?

Implement environment variables within the ConfigMaps and store the variable definitions separately from the master branch where the ConfigMaps are stored

Generate the ConfigMaps specific to the environment by using a templating language such as Jinja2 and store the ConfigMaps in unique branches of a repository

In the master branch where the ConfigMaps are stored, create a branch for each environment that contains an environment-specific ConfigMap.

Create a unique repository for each environment that contains ConfigMaps for that environment to ensure that each environment can be deployed independently

Question # 12

Refer to the exhibit.

The push_configs.yml playbook returns the error shown.

Which action resolves the error?

Install the Paramiko library on the host that runs Ansible

Generate a new SSH key pair and add the public key to the target machine

Export the ANSIBLE_HOST_KEY_CHECKING=False variable

Comment out the StrictHostKeyChecking=yes line from ansible.cfg

Question # 13

What is a principle of chaos engineering?

common user access on system monitoring infrastructure

proactive testing based on system responsiveness

prevent mistakes that cause infrastructure service disruption

reactive system monitoring for network infrastructure outages

Question # 14

Drag and drop the code snippets from the bottom onto the boxes in the code to complete the docker-compose y ml and the mdex.js files to enable network communication between the containers of a Redis instance and a Node js web application The application must be reachable on the host via port 4001 Not all options are used

Question # 15

An engineer is developing a script that must call an API using a static Bearer token Which solution securely protects the credentials from being retrievable from the source code?

Option A

Option B

Option C

Option D

Question # 16

Refer to the exhibit.

The text represents a syslog message sent from a Linux server to a centralized log system.

Based on the format of the log message, how must the functionality of the log parser be extended to improve search capabilities?

Reverse lookup the IP address to add a hostname field

Convert the date to the time zone of the system

Configure the Linux machine to add a UID field to messages

Filter out the text of the message to speed up searches

Question # 17

Drag and drop the code snippets from the bottom onto the boxes in the code in the Ansible playbook to restart multiple services in the correct sequence Not all options are used

Question # 18

The E-commerce application is being monitored using AppDynamics. AppDynamics has noticed that the application response has degraded and has identified some thread contention that might be the cause of the delays.

Where in the interface does AppDynamics bring this to your attention?

Potential Issues section of an individual transaction

Transaction Score graph of a business transaction

Code Deadlock section of the Event List

Slow Calls and Errors tab of the application

Question # 19

A three-tier web application must be moved to containers. A webserver is already in place, and the middleware container can talk to a central database server. The hostname of the database server is known, but the name of the middleware server must be provided to the webserver.

In which file should the name of the middleware server be configured?

Docker Service discovery daemon

Docker Swarm

Docker Compose

Dynamic Host Configuration Protocol

Question # 20

How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?

All devices that generate syslogs must use agents that process the local logs and transmit them in a specific format to the ELK Stack.

All logs are stored in their unstructured text format, and the ELK Stack performs data analysis by intelligently parsing the logs using machine learning algorithms.

All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.

A single, comprehensive log format is defined on the ELK Stack. All incoming logs, regardless of format, are transformed to match the comprehensive format, and only applicable fields are populated.
