Correct; Unvalidated input cannot be distinguished from valid instructions. Which of the following is not a way of referring to a value in a program? ARP is the data link layer protocol in the OSI model. Transport layer builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system. For example, in a web browser application, the Application layer protocol HTTP packages the data needed to send and receive web page content. 5 C. 6 D. 10. A. A) Physical layer . In TCP/IP, most applications use all the layers, while in OSI simple applications do not use all seven layers. Correct; A Web application does not validate a client’s access to a resource. Activity C. Layout D. Content Provider Answer: C Q4.During an Activity life-cycle, what is the first callback method invoked by the system? d . Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. Each application service logic can be resident in a … IoT Service layer . A. onStop() B. onStart() C. onCreate() D. onRestore() Answer: C DNS OSI layer : This is a domain name system.
