What is an accurate statement about Governance?
Governance involves the establishment of policies and the continuous monitoring of their proper implementation. It is the system by which organizations are directed and controlled, ensuring that policy-making decisions are authorized and enforced throughout the organization. This ensures accountability, fairness, and transparency in all aspects of organizational management.
Which exhibit represents a Type 1 hypervisor?
A.
B.
C.
D.
A Type 1 hypervisor, also known as a bare-metal hypervisor, runs directly on the physical hardware of the host machine. It does not require a host operating system to manage hardware resources; instead, it incorporates the management functions itself. Type 1 hypervisors offer better performance and are more efficient since they do not have the overhead of a host operating system. Exhibit 1 shows a hypervisor kernel running on the physical compute system directly, without an additional operating system layer. Therefore, Exhibit 1 represents a Type 1 hypervisor.
An Ethernet switch has eight ports and all ports must be operational for 24 hours, from Monday through Friday. However, a failure of Port4 occurs as follows:
"¢ Monday = 8 PM to 9 PM
"¢ Wednesday 7 PM to 9 PM
"¢ Thursday = 6 AM to 9 AM
"¢ Saturday = 4 PM to 7 PM
What is the MTTR of Port 4?
MTTR (Mean Time to Repair) is calculated by dividing the total downtime by the number of failures. For Port 4, the downtimes provided are: Monday from 8 PM to 9 PM (1 hour), Wednesday from 7 PM to 9 PM (2 hours), and Thursday from 6 AM to 9 AM (3 hours). The downtime on Saturday is not considered as the question specifies operational days from Monday through Friday. So, the total downtime is 6 hours over 3 incidents, resulting in an MTTR of 2 hours.
What accurately describes an iSCSI HBA?
An iSCSI HBA (Host Bus Adapter) is a hardware device that offloads both iSCSI and TCP/IP processing from the host CPU, thereby freeing up CPU cycles for other applications. This makes data transmission more efficient by handling the protocol processing within the HBA itself.
When using the erasure coding technique in an object-based storage system, data is divided into 12 data segments and 4 coding segments.
What is the maximum number of disk drive failures against which data is protected by the configuration?
In the erasure coding technique, the data is divided into data segments and coding segments, where the coding segments hold the calculated redundancy information. The number of coding segments, which is 4 in this case, directly represents the maximum number of disk drive failures that the system can tolerate while still being able to reconstruct the lost data. Therefore, the maximum number of disk drive failures against which data is protected by this configuration is 4.
