Demo Questions

Question 1
A customer wants to have the server two kilometers away from the storage. The DS8886 offers different host adapter types. 
What type of host adapters are needed for this configuration?
  1. Any host adapter requires SAN distance extension equipment at this distance
  2. Shortwave host adapters
  3. Longwave host adapters
  4. Any host adapters when connected to 62 μm fibre cables
Correct answer: A
Explanation:
Incorrect Answers:D: For 850-nm Gigabit Ethernet, 10-Mbit/sec bandwidth values support link lengths of 220 meters over 62.5-micron fiber and 550 meters over 50-micron fiber.References: http://www.redbooks.ibm.com/redbooks/pdfs/sg248047.pdf  (System z End-to-End Extended Distance Guide)

Question 2
A z/OS customer accidentally deleted data that was in production. 
Which function of the IBM DS8880 family will prevent this?
  1. T10 Data Integrity Field
  2. Active Volume Protection
  3. IBM DFSMSdss
  4. zHyperWrite
Correct answer: C
Explanation:
DFSMSdss copies and moves data to help manage storage, data, and space more efficiently. DFSMSdss provides host system backup and recovery functions. References: https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.idag200/ch1.htm

Question 3
Which Easy Tier feature should be utilized for a DR site to ensure equivalent performance after a fail over?
  1. Heat Map Transfer
  2. Automatic Mode
  3. Volume Data Monitoring
  4. Automatic Intra-tier Balancing
Correct answer: A
Explanation:
You can use the Easy Tier Heat Map Transfer Utility to prepare for data recovery. The Easy Tier Heat Map Transfer Utility moves Easy Tier heat map information from primary to auxiliary storage systems. In this way, the performance characteristics of the auxiliary storage are consistently updated to reflect that of primary storage. Auxiliary storage systems are then workload optimized based on primary storage system usage. References: https://www.ibm.com/support/knowledgecenter/HW213_7.5.0/com.ibm.storage.ssic.help.doc/ds8_recovprep_uui74.html

Question 4
A customer’s IBM DS8000 experienced a heartbeat facility failure and is currently connected to an IBM support center. 
Which action occurs?
  1. Any remote replication is terminated.
  2. A service call is placed for IBM to confirm the call home function.
  3. The ability of the customer to submit problems is suspended.
  4. The IBM DS8000 cache goes into write-through mode until the connection is restored.
Correct answer: B
Explanation:
If the heartbeat information does not reach IBM, a service call to the client will be made to investigate the status of the DS8000. Note: The DS8000 also uses the Call Home facility to send proactive heartbeat information to IBM. A heartbeat is a small message with basic product information so that IBM knows the unit is operational. By sending heartbeats, both IBM and the client ensure that the HMC is always able to initiate a full Call Home to IBM in the case of an error.References: http://www.redbooks.ibm.com/redbooks/pdfs/sg248886.pdfIBM System Storage DS8000: Architecture and Implementation (November 2012), page 457

Question 5
A customer with an IBM TS4500 is using SKLM for encryption management. The customer now wishes to install a DS8888 and needs to understand how licensing will work. 
What should the storage specialist discuss with the customer?
  1. Two additional SKLM server licenses are required.
  2. SKLM is already installed; no additional licenses are required.
  3. SKLM is already licensed, but licenses for encryption drives are required.
  4. A site license for IBM encryption must be purchased.
Correct answer: C
Explanation:
SKLM is licensed based on the number of instances of SKLM server installed.  You also need a Base Function License (BF), which includes Encryption Authorization. References: https://www.ibm.com/support/knowledgecenter/en/ST5GLJ_8.2.0/com.ibm.storage.ssic.help.doc/f2c_license_base_functions.html
