An optical fiber cable comes with the specifications 50/125 um. What do the numbers represent?

• The first number represents the distance for a 10 Gb/s connection; the second number represents the distance for a 1 Gb/s connection.
• The first number represents the diameter of the core; the second number represents the diameter of the cladding in microns.
• The first number represents the diameter of the core; the second number represents the actual diameter cable including the buffer and jacket.
• The first number represents the required distance to single-phase power cabling; the second number represents the required distance to three-phase cabling.

What is the primary reason to install a monitoring system in the data centre?

• To notice abnormalities early so that actions can be taken to avoid disasters
• To create a proper asset database
• To implement automated change management
• To be able to collect data for capacity planning

What is the best practice for cutting holes in the raised floor tile?

• Anywhere as data centre tiles are designed to allow cut-outs anywhere.
• Draw a cross on the tile and when making a cut-out do not touch a line and avoid the corners.
• Draw a line in the middle of the tile and never touch the line when making the cut.
• Cut the tiles at the corner so the pedestals can be used as a vertical cable manager.

systems are designed specifically to protect the structure of a building.

• Pro-inert
• Inergen
• Water sprinkler
• Total Flooding

Do I need to check the local standards if I already comply to international standards?

• Local standards do not to be checked as some countries have too many local standards, which will slow down the data centre construction.
• You need to check the local standards to ensure compliance to these standards.
• Compliance to only international standards is good enough as most local standards are derived from international standards.
• Data centres only need to comply to international standards since they are connected to a worldwide international network infrastructure.

By what are magnetic fields of the type 'H' or 'B' created?

• Magnetic fields are created when an electric current flows; the greater the current, the stronger the magnetic field.
• Magnetic fields are created by the magnetic flux of the earth which varies per month.
• Magnetic fields are created by voltage; the greater the voltage, the stronger the magnetic field.
• Magnetic fields are created when there is a high level of common mode noise (CMN); the greater the common mode noise (CMN), the stronger the magnetic field.

How many monitoring points should be used in Temperature Measurement?

• 1
• 2
• 3
• 4

Which one of the following is an AC Power Quality Anomaly?

• Radio Active Waves
• Attenuation

Which of statements below is true?

• Single-mode cabling can use both LED and laser as a light source.
• Single-mode cabling is more expensive than multi-mode cabling.
• Multi-mode cabling can cross longer distances.
• Multi-mode cabling is more expensive than single-mode cabling.
