Environments must be provisioned consistently using the same inputs. C. Redeployments cause varying environment definitions. D. Service overlap is encouraged to cater for unique environment needs. E.

A. rm -rf old_project B. rm -r old_project C. rmdir -p old_project D. rmdir old_project 20. What are the two purposes for using a VLAN in a network? (Choose two) A. It is used to create the routing table. B. It creates a collection of MAC addresses. C. It is used for VM network traffic. D. It segments a network. E. It creates a broadcast domain. 21. Users cannot access a webserver and after the traffic is captured. the capture tool shows an ICMP packet that reports “time exceeded in-transit”. What is the cause of this webserver access issue? A. A router along the path is misrouting the packets in a wrong direction. B. A router along the path has the wrong time. C. The server is too far away and the packets require too much time to reach it D. The server is too loaded and the connection could not be handled in time 22. A REST API service requires authentication based on the username and password. The user “john” has the password “384279060” and the Base64 encoding of those credentials is “am9objowMTIzNDU2Nzg=”. Which method completes an authentication request? A. The header must include: Authorization: Bearer am9obJowMTlzNDU2Nzg= B. The payload must include: Authorization: Bearer am9objowMTIzNDU2Nzg= C.

Users cannot access a webserver and after the traffic is captured, the capture too* shows an ICMP packet that reports “communication administratively prohibited” What Is the cause of this webserver access Issue? A. An access list along the path is blocking the traffic B. The traffic is not allowed to be translated with NAT and dropped. C. Users must authenticate on the webserver to access It D. A router along the path is overloaded and thus dropping traffic 26. In which situation would an edge computing solution be used? A. where low latency is needed B. where high CPU throughput is needed C. where fast memory is needed D. where high disk space is needed 27. How does requesting a synchronous API operation differ from requesting an asynchronous API operation?
