You created a SQL Tuning Set as a part of the workload capturing. What information is captured as part of this process?（） the SQL text SQL。 the execution plan。 the execution context。 the execution frequency。 the system change number (SCN)。 In AIX 5L and later， the operating system supports the /proc filesystem. What would be the best description of the /proc filesystem？（）  It is a pseudo filesystem that maps processes and kernel data structures to corresponding files.。  It is a JFS mounted filesystem that provides an exact representation of what is happening to a proces at a single and discrete point of time.。  It is a JFS mounted filesystem that maps processes and read-only files related to these processes.。  It is a pseudo filesystem that contains data that represents the state of the parent processes （but not their threads） in a system.。 The pSeries sales representative has done an excellent job in educating the customer on the benefits of working with IBM.  The customer is planning to implement their first ERP application.  This new application will be critical to running their business.  The customer has only a competitor’s UNIX systemcurrently installed.  They are interested in obtaining a proposal from IBM. In addition to the AIX hardware and HACMP software， what else should be included in the IBM proposal for the new ERP solution？（） I/T services and education to help with the implementation of the hardware and software。 A Supportline specialist to work directly with the customer to manage any issues that arise。 The services required to move the currently installed applications from the competitor’s systems to the IBM systems。 A slimmed down solution to ensure that the IBM solution is less expensive than the competitor’s solutio。 A network administrator provides an IP address of 128.135.0.142 and a subnet mask of 255.0.0.0.  Once a ping is attempted， it fails.  Which of the following options is the most probable cause of the failed ping？（） 0 is not valid in an IP address。 128 is a reserved network。 The subnet mask should be 255.255.0.0. since it is a class B。 A network problem has occurred since IP and subnet are valid。
