A customer wants to restrict access to a subnet in their network to a discreet number of employers. The customer tried to restrict it through firewalls, but this solution only handles the IP addresses.
Which solution will allow them to restrict access to z/OS users?

• A.SERVAUTH class in RACF
• B.Certificate management in z/OS
• C.Network Address Port Translation (NAPT) in z/OS Communications Server
• D.IP defensive filtering in z/OS Communications Server

Which of the following is considered an element of high availability for a z/OS customer?

• A.GRS STAR
• B.Sysplex Failure management (SFM)
• C.Modified Indirect Data Address Word (MIDAW) facility
• D.Shared memory Communications over RDMA (SMC-R) exploitation

A government customer is planning a large scale IT project. They have many kinds of workload requirements including OLTP transactions, file transfer, short and long batch jobs, OLAP workload etc. The customer will decide between z Systems and Unix servers.
They want to know if the TPC/C value is a fair benchmark to closely reflect their workload needs before opening the bid process.
Which of the following is the appropriate response?

• A.IBM doesn't provide benchmarks like TPC/C , so they can only reference other accounts in the same industry and bid accordingly.
• B.IBM would like to do a benchmark for the customer's workloads; then bid accordingly.
• C.IBM can do an OLTP benchmark on z Systems and then derive an equivalent TPC/C number prior to the bid.
• D.IBM can convert IBM MIPS into TPC/C for the bid purpose.

A z Systems technical specialist discovers in a z13 pre-install TDA review that the customer has changed the initial plan. The new plan will include connecting the z13 to a sysplex with two zEC12 machines.

• A.Network Connectivity FICON Chanel Connectivity Available power plugs
• B.Coupling Links FICON card rebalance Bulk Power Regulators
• C.Coupling Links FICON Chanel Connectivity Available power receptacles
• D.OSA Links HiperSockets Connectivity Available power plugs

A client plans to establish an "Infrastructure as a Service" cloud service model. Currently, this client using only DB2 on z/OS as its central data repository.
