Click the Exhibit button. An administrator is creating a vApp for a multi-tiered web application. The vApp has been configured as shown in the exhibit. Testing of the vApp indicates that attempts to communicate with the web server on Dev_Web_01 fail. The developer wants to be sure the database server OS is completely started before the other servers power on. The developer also wants to minimize recovery time. What changes to the vApp configuration will correct the issues?
A. Move the Dev_Web_01 virtual machine to Group 3 and increase the time value
B. Move the Dev_App_01 virtual machine to Group 1 and increase the time value
C. Move the Dev_Web_01 virtual machine to Group 3, decrease the time value and check VMware Tools are ready
D. Move the Dev_Web_01 virtual machine to Group 3, increase the time value and check VMware Tools are ready
Correct Answer: D
Explanation/Reference:
There’s no Group 3 in the screenshot but it’s implied that you would create it. Moving Dev_Web_01 to Group 3 will ensure that *Dev_SQL_01* & Dev_App_01 have had amble time to power-on and start their services before the web application loads.
A likely reason that the web application (the front-end) is unreachable may be due to the Dev_SQL_01 server (the back-end) still loading.
By placing Dev_Web_01 and Dev_SQL_01 in the same Start Order group, they will power-on at exactly the same time. Ticking the option “VMware Tools are ready” will only allow a VM to start before the specified delay. Starting Dev_Web_01 earlier than it already is (not possible in this scenario as its already powering on immediately) would only cause more connectivity issues, not less.
Moving Dev_Web_01 to Group 3 will ensure that Dev_SQL_01 & Dev_App_01 have had amble time to power-on and start their services before the web application loads.
