How does virtualization help with disaster recovery within a data center? -Power is always provided. -Less energy is consumed. -Server provisioning is faster. -Hardware does not have to be identical.

Hardware does not have to be identical. Disaster recovery is how a company goes about accessing applications, data, and the hardware that might be affected during a disaster. Virtualization provides hardware independence, which means the disaster recovery site does not have to have the exact equipment as the equipment in production. Server provisioning is relevant when a server is built for the first time. Although data centers do have backup generators, the entire data center is designed for disaster recovery, One particular data center could never guarantee that the data center itself would never be without power.

A device has an IPv6 address of 2001:0DB8:75a3:0214:0607:1234:aa10:ba01 /64. What is the host identifier of the device? -2001:0DB8:75a3 -0607:1234:aa10:ba01 -2001:0DB8 -ba01

0607:1234:aa10:ba01 An IPv6 address is made up of 128 bits that are represented as eight blocks of four hexadecimal digits that are called hextets. Because each hexadecimal digit represents four bits, each hextet represents 16 bits. The /64 network prefix indicates that the first 64 bits, or first four hextets, represent the network portion of the address. Because there are 128 bits in an IPv6 address, this leaves the last 64 bits, or last four hextets, to represent the host identifier. The value for the last four hextets is 0607:1234:aa10:ba01.
