Chapter 4 Cram Quiz Answers
Chapter 4 Cram Quiz Answers
| 1. | C is correct. LUN masking is the method of obscuring LUNs on a per host basis. |
| 2. | C is correct. vmhba0 identifies the HBA adapter number in the ESX host. The second number, which is 2 in this example, identifies the target. The third number, which is 3, identifies the LUN number. The fourth number, which is 4, identifies the partition number. |
| 3. | A and B are correct. The two iSCSI methods supported by ESX are Static Configuration and SendTargets. |
| 4. | B is correct. iSCSI uses CHAP as the default method of authentication. |
| 5. | A, True, is correct. VMware best practices recommend that iSCSI be separated on its own network. |
| 6. | C is correct. IQN stands for iSCSI Qualified Name. All other answers are incorrect. |
| 7. | B is the correct response. No_root_squash enables the root user or UID extended privilege access to NFS. |
| 8. | B, False, is the correct response. NFS only requires a VMkernel port group to allow IP communication to the storage. |
| 9. | A is the correct response. A VMFS datastore can have a maximum of 2TB—512 bytes without extents. |
| 10. | B is the best response. You can grow a VMFS volume but only if there is adjacent space available. |
| 11. | A is correct. The Pluggable Storage Architecture has two submodules, the SATP and the PSP. |
| 12. | B is correct. By default, virtual disks are created with the Thick type. |
| 13. | C is correct. For any type of clustering, the Eagerzeroedthick virtual disk type must be selected, which would zero out all the space on that virtual disk and is a requirement for clustering to function properly. |
| 14. | A is the best response. You can change the virtual disk type using a number of different ways including Storage VMotion, cloning, or even inflating the disk and forcing the writes of zeroes across all free space. |
