cone testing

change lead time

age of codebase

Question 2

What is the purpose of using a build tool in software development?

It complies source code into binaries and executables.

It provides a way to edit source code using a graphical interface.

It is a manual process that is followed to build software.

It tracks bugs and incidents in a built application.

Question 3

A company has experienced serious growth and the hosted applications are getting more and more hits. Based on the increased work load, applications have started to show signs of reduced performance, which is affecting the user experience.
Which two server metrics should be tracked to ensure that the customer experience remains within acceptable limits? (Choose two.)

application feature sprawl

CPU peak usage

CPU average usage

microservices count

CPU frequency

Question 4

Microservices architecture pattern has been applied and the system has been architected as a set of services. Each service is deployed as a set of instances for throughput and availability. In which two ways are these services packaged and deployed? (Choose two.)

Service instances must be isolated from one another.

Service must be independently deployable and scalable.

Service are written using the same languages, frameworks, and framework versions.

Service must be dependent, deployable, and scalable.

Service instances do not need to be isolated from one another.

Question 5

Which type of security testing should be performed as a part of a CI/CD pipeline by analyzing the source code itself without compiling the code into a running executable?

Dynamic Application Security Testing

Runtime Application Health-Protection

Continuous Application Security Testing

Static Analysis Security Testing

Question 6

What are two reasons a Docker golden image should be updated? (Choose two.)

when there is a change to a username or password in the Docker secrets

when the application has a new release

when a fix for a security vulnerability is released

when a change is needed to an environment variable in the Dockerfile

when the base image is nearing the end of life

Question 7

Which step must be taken to enable centralized logging in a Kubernetes environment?

No steps need to be take

The master node automatically aggregates logs from all worker nodes and stores them on the specified persistent volume.

Create a CustomResourceDefinition in each deployment that specifies the IP or names the log collector.

Deploy a sidecar node that aggregates logs from the entire cluster.

Create a DaemonSet that deploys a container with a logging agent on every node in the cluster.

Question 8

What is as responsibility for teams running private cloud servers that is less of a concern when running in the public cloud?

cost

metrics and monitoring

hardware maintenance

credentials management

Question 9

To make logging searches more efficient and useful in Kibana, an Administrator wants to implement index patterns around the hostname of some software systems. Where should this be configured?

Configure a new JSON object in Kibana.

Create a search index in Logstash.

Create an index pattern in Kibana.

Create a time filter on Kibana to look at time only.

Question 10

What are two advantages of using Configuration Management Tools? (Choose two.)

reduction in policy violations caused by human errors

reduction in administration costs

reduction in network changes already performed automatically

reduction of on-premises networking equipment

reduction in networking team skills

Question 11

An interface on a router as a Layer 3 link has been configured to another device by updating an Ansible playbook that is executed via a CI/CD pipeline. The Ansible playbook was written to push the configuration change using the ios_config module. Which automated test validates that the interface is functioning as it should?

Add a pipeline step that runs the playbook a second typ

If it does not modify the device on the second run, then the interface is correctly configured.

Automated testing is already built in because the playbook execution is successful only after Ansible validates that it applied the change.

Add a pipeline step that captures and parses the packet flow for the interface.

Add a pipeline step that captures and parses the show ip interface output so that the operational state can be referenced.

Question 12

Which two practices help make the security of an application a more integral part of the software development lifecycle? (Choose two.)

Add a step to the CI/CD pipeline that runs a dynamic code analysis tool during the pipeline execution.

Add a step to the CI/CD pipeline that runs a static code analysis tool during the pipeline execution.

Use only software modules that are written by the internal team.

Add a step to the CI/CD pipeline to modify the release plan so that updated versions of the software are made available more often.

Ensure that the code repository server has enabled drive encryption and stores the keys on a Trusted Platform Module or Hardware Security Module.

Question 13

Refer to the exhibit. A developer needs to scale the existing pods within the worked nodes. Which object should be edited to achieve this goal?

ReplicaSet

PriorityClass

Deployment

Pod

Question 14

A developer has created a deployment that should launch a pod to run their database service. The pod should launch with a metadata name of “Cisco-DB," and the developer has added it to the "Cisco" namespace in their deployment.
