Devnet Exam Review Questions & Answers Solved 100% Correct!!

A company has written a script that creates a log bundle from the Cisco DNA Center every day. The script runs without error and the log bundles are produced. However, when the script is run during business hours, people report poor voice quality of phone calls. What explains this behavior - The application is running in the Voice VLAN and causes delays and jitter in the subne A developer is reviewing a code that was written by a colleague. It runs fine, but there are many lines of code to do a seemingly simple task repeatedly. Which action organizes the code? - Using functions, rewrite any pieces of code that are repeated. A developer is troubleshooting an API with the given API documentation and cURL command. What is the cause of this problem? - The authorization header is missing or incomplete A developer is writing an application that uses a REST API and the application requires a valid response from the API. Which element of the response is used in the conditional check? - status code A function my_func() returns True when it executes normally. Which Python snippettests my_func()? - tTrue(my_func()) A process on the host wants to access the service running inside this Docker container. Which port is used to make a connection? - port 3000 A REST API returns this JSON output for a GET HTTP request, which has been assigned to a variable called "vegetables". Using Python, which output is the result of this command? print(filter(lambda 1: 1[ 'type' ] == 'fruit', vegetables) [0]['items'][0]['items'][0]) - D. kiwi Administrator cant access server getting ICMP exceeded message - Server is very far away An application calls a REST API and expects a result set of more than 550 records, but each time the call is made, only 25 are returned. Which feature limits the amount of data that is returned by the API? A - payload limitAn authentication script fails to connect to an internal server exactly 1 out of 2 times it is executed. This behavior is seen from different clients. Which networking device must be at fault? - load balancer Before which process is code review performed when version control is used? - branching code Cisco DNA Center provides the capability to send an HTTP _______________ request to the API endpoint https://DNA-C_API_ADDRESS/api/v1/network-device/and receive the network _______________ list in _______________ format. - authentication parameter json Cisco DNA Center provides the capability to send an HTTP _______________ request to the API endpoint https://DNA-C_API_ADDRESS/api/v1/network-device/and receive the network _______________ list in _______________ format. - Cisco DNA Center provides the capability to send an HTTP GET request to the API endpoint https://DNA-C_API_ADDRESS/api/v1/network-device/ and receive the network device list in json format DNS server firewall load balancer reverse proxy - Contains a database of public IP addresses and their associated hostnames and often resolves or translates those names to IP addresses as requested enforces a set of rules about which data packets are allowed to enter the network distribute network and application traffic across different servers retrieves resources on behalf of a client from one or more servers, then returns resources to the client, thus appearing as if they originated from the service itself DRAG AND DROP HTTP 401 HTTP 404 HTTP 403HTTP 400 - Unauthorized Not Found Forbidden Bad Request Drag and Drop - HTTP HTTP/2—- gRPC HTTPS—- Restconf SSH——- netconf SOAP DRAG AND DROP - Item1- postItem2- base_urlItem3- organizationsItem4- networksItem5- api_keyItem6- application/jsonItem7- dataItem8- network_name Drag and DROP - User represenst an agent Dialog represents a call Media Represent's a user state Queue Represents a skill Team Represent a group of users SystemInfo Represents the current state Sendslogs Represent Client Side logging Drag and Drop - xml or json ——————- Content ssh get,post,put,patch,delete—— Operations HTTPS ————————- Transport Drag and drop the code from the left onto the item numbers on the right to complete the Meraki code to obtain a list of clients which have used this network - getbase_url networks network_id clients api_key application/json params timespan 432000 DRAG AND DROP the HTTP METHODS from the left onto their generally accepted corresponding create, read, update, and delete operations on the right. - DELETE DELETE PATCH UPDATE POST CREATE PUT REPLACE GET READ Drag and drop the requests from the left into the correct order on the right to create and check the path trace between two devices using Cisco DNA center API. - Step 1 Post api/system/v1/auth/tokenStep 2 GET /api/network-devices and choose ip of src and dstStep 3 POST /api/v1/flow-analysisStep 4 GET /api/v1/flow-analysis/{flowAnalysisid} Drag and drop the variables from the left onto the item numbers on the right that match the missing assignments in the exhibit. - item1-$BACKUPTIME item2-$SOURCEFOLDER item3-$DESTINATION DRAG DROP - A.request header B.request payload C.http requestD.http response E.response headers F.response payload Fill in the blank to complete the query parameter and value so that the result set is returned in reverse chronological order (most recent first) based on when messages were entered.
