Question 1

Which Class of Fires involves energized electrical equipment?

AClass A

BClass B

CClass C

DClass K

Answer : C

Class C fires involve energized electrical equipment, such as computers, servers, switches, cables, and wiring. These fires require the use of non-conductive extinguishing agents, such as carbon dioxide, dry chemical, or clean agent, to prevent electrical shock and damage to the equipment. Water-based extinguishers, such as Class A or K, are not suitable for Class C fires, as water can conduct electricity and cause electrocution or short circuits.

Question 2

Which one of the following does a Physical Infrastructure consists of in a Data Centre?

AHub

BSwitch

CRack

DServer

Answer : C

A physical infrastructure in a Data Center consists of racks, which are metal frames used to store and organize server and other IT equipment. The racks are usually arranged in rows and columns, and they can be used to hold servers, storage devices, and other pieces of IT equipment. The racks can also be used to organize cables and other components to ensure that the Data Center is kept organized and efficient.

Question 3

A UPS has an internal battery tester, do you still need to separately test the batteries at block level?

ANo, as mentioned the battery tester is already built-in the UPS.

BNo, the UPS will automatically generate and alarm when de battery voltage is too low to operate.

CYes, the UPS will only test the batteries at string level which only gives an indication on the overall status of the battery string. Measurements at block level will provide more detailed information on the status and remaining lifetime of the batteries itself.

DTesting batteries using the built-in battery tester or resting the batteries at block level does not increase the battery lifetime, therefore it is not recommended.

Answer : C

Block-level testing identifies weak or failing individual batteries that may not show up in string-level tests, enhancing overall system reliability.

Question 4

Which type of Humidifier is composed of water-filled canister containing electrodes?

AInfrared Humidifiers

BWater Canister Humidifier

CSteam Canister Humidifier

DUltrasonic Humidifier

Answer : C

A steam canister humidifier is a type of humidifier that uses electricity to heat water in a canister containing electrodes. The water conductivity and the water level determine the amount of current and steam production. The steam canister humidifier is also known as an electrode boiler humidifier or an electrode steam humidifier123.

Question 5

An optical fiber cable comes with the specifications 50/125 um.

What do the numbers represent?

AThe first number represents the distance for a 10 Gb/s connection; the second number represents the distance for a 1 Gb/s connection.

BThe first number represents the diameter of the core; the second number represents the diameter of the cladding in microns.

CThe first number represents the diameter of the core; the second number represents the actual diameter cable including the buffer and jacket.

DThe first number represents the required distance to single-phase power cabling; the second number represents the required distance to three-phase cabling.

Answer : B

Optical fiber cables are composed of a core, a cladding, and a coating. The core is the central part of the fiber that carries the light signal. The cladding is the layer surrounding the core that reflects the light back into the core and prevents signal loss. The coating is the protective layer that covers the cladding and provides mechanical strength and environmental protection. The specifications of an optical fiber cable indicate the dimensions of the core and the cladding in microns (m), which are one millionth of a meter. For example, a 50/125 m cable has a core diameter of 50 m and a cladding diameter of 125 m. The coating diameter is usually 250 m, but it is not part of the specifications.

Question 6

Which one of the following is used in Measuring Business Value?

ARegeneration Cost

BScalability

CReliability

DUpfront Cost

Answer : B

Measuring business value is the process of assessing the benefits and costs of IT investments and initiatives in relation to the strategic objectives and priorities of the organization. One of the factors that can be used to measure business value is scalability, which is the ability of a system or component to handle increasing workloads or demands without compromising performance, quality, or functionality. Scalability is important for business value because it enables the organization to adapt to changing market conditions, customer expectations, and growth opportunities. Scalability can also reduce operational costs, increase efficiency, and improve customer satisfaction. Therefore, scalability is one of the factors that can be used in measuring business value.

Question 7

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

APro-inert

BInergen

CWater sprinkler

DTotal Flooding

Answer : C

Water sprinkler systems are designed to protect the structure of a building from fire by suppressing or extinguishing the flames with water. Water sprinkler systems are typically installed in the ceiling or walls of a building and are activated by heat or smoke detectors. Water sprinkler systems can reduce the risk of fire spreading and causing structural damage to the building.
