A developer is creating a Python script to catch errors using REST API calls and to aid in debugging. Drag and drop the code from the bottom onto the box where the code is missing to implement control flow for REST API errors. Not all options are used.
Using APIs
Click on the GET Resource button above to view resources that will help with this question.
An engineer is managing a data center with 6000 Cisco UCS servers installed and running. The engineer has been asked to identify all resources where the model is in the UCSB family and the available memory is less than or equal to 5 GB.
Which REST API call accomplishes this task?

Cisco Core Platforms and APIs
Network Fundamentals
Refer to the exhibit. A company has extended networking from the data center to the cloud through Transit VPC.
Which two statements describe the benefits of this approach? (Choose two.)
Dynamic routing combined with multi-AZ deployment creates a robust network infrastructure.
VPC virtual gateways provide highly available connections to virtual networks.
Dedicated VPC simplifies load balancing by combining internal and external web services.
VPC virtual gateways provide more secure connections to virtual networks.
Dedicated VPC simplifies routing by not combining this service with other shared services.
Network Fundamentals
Refer to the exhibit. This script uses ciscoyang to configure two VRF instances on a Cisco IOS-XR device using the Yang NETCONF type.
Which two words are required to complete the script? (Choose two.)
ensure
commit
false
replace
none
Cisco Core Platforms and APIs
Network Fundamentals
An organization manages a large cloud-deployed application that employs a microservices architecture. No notable issues occur with downtime because the services of this application are redundantly deployed over three or more data center regions. However, several times a week reports are received about application slowness. The container orchestration logs show faults in a variety of containers that cause them to fail and then spin up brand new.
Which action must be taken to improve the resiliency design of the application while maintaining current scale?
Which action must be taken to improve the resiliency design of the application while maintaining current scale?
Update the base image of the containers.
Test the execution of the application with another cloud services platform.
Increase the number of containers running per service.
Add consistent try/catch(exception) clauses to the code.
Application Deployment and Security
Security Fundamentals
Refer to the exhibit. This cURL POST request creates an OAuth access token for authentication with FDM API requests.
What is the purpose of the file @token_data that cURL is handling?
This file is given as input to store the access token received from FDM.
This file is used to send authentication-related headers.
This file contains raw data that is needed for token authentication.
This file is a container to log possible error responses in the request.
Application Deployment and Security
Using APIs
What is a data privacy concern when designing data storage?
Data must be kept for as long as necessary.
Storage must be designed to enable data maximization.
Data must be retained in secure data storage after use.
Storage must be designed to enforce encryption in transit.
Network Fundamentals
Security Fundamentals
Refer to the exhibit. The application follows a containerized microservices architecture that has one container per microservice. The microservices communicate with each other by using REST APIs. The double-headed arrows in the diagram display chains of synchronous HTTP calls needed for a single user request.
Which action ensures the resilience of the application in the scope of a single user request?
Implement retries with exponential backoff during HTTP API calls.
Set up multiple instances of each microservice in active/active mode by using the Orchestrator.
Redesign the application to be separated into these three layers: Presentation, API, and Data.
Create two virtual machines that each host an instance of the application and set up a cluster.

Using APIs
Which database type should be used with highly structured data and provides support for ACID transactions?
time series
document
graph
relational
