1.What does N_Port ID Virtualization (NPIV) functionality provide to a DL4200?
A.Disk library failover on a multilibrary configuration in a switched fabric environment
B.Disk library failover on a multilibrary configuration in an arbitrated loop environment
C.Engine failover on a multinode configuration in a switched fabric environment
D.Engine failover on a multinode configuration in an arbitrated loop environment
Answer:C
2.Click the Exhibit button.A customer has a DL4200 connected to two switches in the same fabric, as shown in the exhibit. Windows Backup Server X is zoned to port 1 on Engine A and Windows Backup Server Y is zoned to port 7 on Engine B. Active Engine Failover has been configured and is active.Both backup servers are performing backups at the same time to their respective engines. Engine A has a failure and all virtual services fail over to Engine B.
The backup administrator has verified that failover has occurred as expected but Backup X is unable to see its virtual resources through the surviving engine even after rescanning the SCSI bus.What is the problem?
A.Engine to switch cabling is incorrect
B.Engines are connected to different switches
C.Lack of PowerPath configuration on the backup servers
D.Missing EMC NetWorker DL-Failover license
Answer:A
3.What should be used to configure and manage the EMC Disk Library?
A.EMC ControlCenter for EMC Disk Library
B.EMC Disk Library Console software
C.EMC Disk Library Navisphere software
D.Management is integrated with the backup application
電磁兼容性（EMC）是指設備或系統在其電磁環境中符合要求運行並不對其環境中的任何設備產生無法忍受的電磁幹擾的能力。因此，EMC包括兩個方面的要求：壹方面是指設備在正常運行過程中對所在環境產生的電磁幹擾不能超過壹定的限值；另壹方面是指器具對所在環境中存在的電磁幹擾具有壹定程度的抗擾度，即電磁敏感性。所謂電磁幹擾是指任何能使設備或系統性能降級的電磁現象。而所謂電磁幹擾是指因電磁幹擾而引起的設備或系統的性能下降。
