To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) TIBCO EMS must be installed before installing TIBCO Runtime Agent - This statement is incorrect. TIBCO EMS (Enterprise Messaging Service) is a messaging middleware that is commonly used with TIBCO products, but it is not a prerequisite for installing TIBCO Runtime Agent.
Option B) A TIBCO Runtime Agent installation can use an earlier TIBCO Rendezvous installation - This statement is correct. TIBCO Rendezvous is a messaging platform used by TIBCO products, including TIBCO Runtime Agent. Therefore, if an earlier version of TIBCO Rendezvous is already installed, it can be used during the installation of TIBCO Runtime Agent.
Option C) TIBCO Administrator must be installed before installing TIBCO ActiveMatrix BusinessWorks - This statement is incorrect. TIBCO Administrator is a management tool used for monitoring and administering TIBCO products, including TIBCO ActiveMatrix BusinessWorks. However, it is not a prerequisite for installing TIBCO ActiveMatrix BusinessWorks.
Option D) TIBCO ActiveMatrix BusinessWorks can use a preinstalled JRE or a JRE installed by TIBCO Runtime Agent installer - This statement is correct. TIBCO ActiveMatrix BusinessWorks, like many Java-based applications, requires a Java Runtime Environment (JRE) to run. It can use either a preinstalled JRE or a JRE installed by the TIBCO Runtime Agent installer.
Based on the explanations above, the two statements that are true about installing TIBCO ActiveMatrix BusinessWorks are:
B) A TIBCO Runtime Agent installation can use an earlier TIBCO Rendezvous installation.
D) TIBCO ActiveMatrix BusinessWorks can use a preinstalled JRE or a JRE installed by TIBCO Runtime Agent installer.
Therefore, the correct answer is B and D.
