Refer to the exhibit. A collaboration engineer has developed a script to automate the gathering of information by providing the email address of the individual. When the engineer tests the script, a 401 error is received. Which command fixes the script?

Add “Authorization”: “Bearer ” to the headers.

Add “Authentication”: “Basic ” in the base_url after “https://”.

Add “:@” in the base_url after “https://”.

Add “Authentication”: “Bearer ” to the headers.

A developer pushes an application to production. The application receives a webhook over HTTPS without a secret. The webhook information contains credentials to service in cleartext. When the information is received, it is stored in the database with an SHA-256 hash. Credentials to the database are accessed at runtime through the use of a vault service.While troubleshooting, the developer sets the logging to debug to view the message from the webhook. What is the security issue in this scenario?

During the transport of webhook messages, the credentials could be unencrypted and leaked.

Database credentials should be accessed by using environment variables defined at runtime.

During the transport of webhook messages, the credentials could be unencrypted and leaked.

During logging, debugging should be disabled for the webhook message.

Hashing the credentials in the database is not secure enough; the credentials should be encrypted.

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?

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

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.

Refer to the exhibit. A network engineer wants use API update information about device interfaces. The network devices are deployed in a Cisco DevNet Sandbox and have running interfaces. Which value is suitable as the headers variable?A. {'Content-Type': 'application/yang.data+yaml', 'Accept': 'application/yang.data+yaml'}

{'Content-Type': 'application/yang.data+utf8l','Accept': 'application/yang.data+utf8'}

{'Content-Type': 'application/yang.data+json','Accept': 'application/yang.data+json'}

Refer to the exhibit. A developer can access the TLS REST API on server A, but cannot access the API on server B. The developer can ping server B. When the developer performs a packet capture on the TLS REST API port on server B, the capture shows that the packet arrived and the server responded. What causes the issue?

Port 443 is blocked on the incoming interface of firewall B.

Port 80 is blocked on the outgoing interface of firewall B.

Port 443 is blocked on the outgoing interface of firewall A.

Port 443 is blocked on the incoming interface of firewall B.

Port 80 is blocked on the incoming interface of firewall A.

How are operations on REST APIs performed as compared to RPC APIs?

In a REST API, operations are performed on an object (node) that is identified by a URL, but RPC APIs are operation-oriented.

In a REST API, operations are performed on an external resource that is defined on the API, but the RCP APIs are resource-oriented.

In a REST API, operations are performed on a platform that is identified by the URL, but RPC APIs are platform-oriented.

In a REST API, operations are performed on an internal resource that is defined on the API, but RPC APIs are resource-oriented.

The platform provides a ready-to-go platform for HD video and audio conferencing.

Applications are added to the platform from the desktop remotely.

The platform includes an enterprise-class IM engine.

What is a benefit of using a code review process in application development?

eliminates common mistakes during development

accelerates the deployment of new features in an existing application

provides version control during code development

enables the quick deployment of new code

eliminates common mistakes during development

What is a benefit of a distributed version control system?

allows users to work on the codebase even when not connected to the Internet

encourages users to commit small places of work to the system more frequently

ensures that all code meets minimum standards before being committed to the system

allows users to work on the codebase even when not connected to the Internet

ensures that all code is tested before being committed to the system

What is a procedural component of CI/CD pipelines?

Bundled artifacts must be generated.

Every test must pass for the pipeline to continue its execution.

Some tests fall without stopping the pipeline execution.

The release label that identifies the build is optional.

Refer to the exhibit. What are two characteristics of the NETCONF response? (Choose two.)

ietf-ospf imports ietf-routing.

redistribution is a module of type cisco-ospf.

ospf is defined by the ietf-ospf module.

ietf-ospf imports ietf-routing.

NAT is misconfigured on the firewall.

The proxy server that rewrites traffic is misconfigured.

The router is sending the traffic to server 1 instead of server 2.

The switch is forwarding IP traffic to the wrong VLAN.

NAT is misconfigured on the firewall.
