What function on VMware allows the manual or automatic distribution of VM's between hosts for a balanced computing resourse?

What function on VMware allows the manual or automatic distribution of VM's between hosts for a balanced computing resourse?

• X-Switch vMotion
• DRS
• HA
• vMotion 

EXPLANATION

VMware DRS (Distributed Resource Scheduler) is a utility that balances computing workloads with available resources in a virtualized environment. The utility is part of a virtualization suite called VMware Infrastructure 3.
With VMware DRS, users define the rules for allocation of physical resources among virtual machines. The utility can be configured for manual or automatic control. Resource pools can be easily added, removed or reorganized. If desired, resource pools can be isolated between different business units. If the workload on one or more virtual machines drastically changes, VMware DRS redistributes the virtual machines among the physical servers. If the overall workload decreases, some of the physical servers can be temporarily powered-down and the workload consolidated.

What kind of connectors can be used to connect a PC power supply to a hard drive?

What kind of connectors can be used to connect a PC power supply to a hard drive?

• Molex
• P9
• AT
• Mini-molex 

EXPLANATION

A molex connector has cylindrical spring-metal pins that fit into cylindrical spring-metal sockets. The pins and sockets are held in a rectangular matrix in a nylon shell. The connector typically has two to 24 contacts and is polarized or keyed to ensure correct orientation. Pins and sockets can be arranged in any combination in a single housing, and each housing can be either male or female.
There are three typical pin sizes: 1.57 mm (0.062 in), 2.13 mm (0.084 in), and 2.36 mm (0.093 in). The 1.57 mm pin can carry 5 A of current, while the 2.36 mm can carry 8.5 A. Because the pins have a large contact surface area and fit tightly, these connectors are typically used for power.

Linux and Unix systems typically track 3 timestamps in file inodes: atime, ctime, and mtime. The "a" in atime means access. The "m" in mtime means modify. What does the "c" in ctime mean?

Linux and Unix systems typically track 3 timestamps in file inodes: atime, ctime, and mtime. The "a" in atime means access. The "m" in mtime means modify. What does the "c" in ctime mean?

• create
• cache
• change
• copy-on-write 

 

EXPLANATION

"c" in ctime means change.  Specifically, a change to the inode's status, eg, permissions, ownership, link count, file size, etc.
http://man7.org/linux/man-pages/man7/inode.7.html
"Last status change timestamp (ctime) stat.st_ctime; statx.stx_ctime"

http://www.linux-mag.com/id/8658/
"Timestamps telling when the inode itself was last change (ctime, changing time), the file content was last modified (mtime or modification time), and when the file was last accessed (atime or access time)"

In SQL, the function select datepart(dw,getdate()) returns a number representing the current day of the week. You want to use 1 for Monday, 2 for Tuesday, up to 7 for Sunday. How do you set this?

In SQL, the function select datepart(dw,getdate()) returns a number representing the current day of the week. You want to use 1 for Monday, 2 for Tuesday, up to 7 for Sunday. How do you set this?

• set datefirst 0;
• set datefirst 2;
• set datefirst 7;
• set datefirst 1; 

EXPLANATION

Datefirst says which day of the week will be treated as the start of the week and return the value 1,
When setting Datefirst, 1 means Monday will be the start of the week. The default (7) means Sunday will be the start of the week. Zero is not a valid option and does not change the current setting.
