NEW QUESTION # 16
Which one of the following is an Objective of Data Center Fire Protection?
- A. Information
- B. Depression
- C. Suppression
- D. Representation
Answer: C
Explanation:
The objective of data center fire protection is to suppress or extinguish a fire before it can cause significant damage to the equipment, personnel, or business continuity. Fire suppression systems are designed to reduce the heat, oxygen, or fuel elements of the fire triangle, and to limit the spread of fire and smoke. Fire suppression systems can be classified into two types: water-based and gas-based. Water-based systems include sprinklers, mist, and water spray systems, which use water as the extinguishing agent. Gas-based systems include inert gas, halocarbon, and clean agent systems, which use gases or chemicals as the extinguishing agent. The choice of fire suppression system depends on several factors, such as the fire risk, the type of fuel, the environmental impact, the reliability, the cost, and the compatibility with the data center equipment and operations.

NEW QUESTION # 17
Mean time between failures is best considered a measure of:
- A. Cost
- B. Duration
- C. Size
- D. Reliability
Answer: D
Explanation:
Mean time between failures (MTBF) is a measure of the reliability of a system or component. It represents the average time that a system or component will operate before it fails. The higher the MTBF, the more reliable the system or component is. MTBF is calculated by dividing the total time of operation by the number of failures that occur during that time. MTBF is used to compare the reliability of similar systems or components, and to help with maintenance planning, inventory management, and system design.

NEW QUESTION # 18
What should be a consideration when having casters (rollers/wheels) or feet under the rack?
- A. Casters and feet should be of a soft material, for example rubber, to avoid damage to the raised floor tile.
- B. Casters and feet should not be locked to ensure the racks are still able to be moved to another position.
- C. Skirts at the bottom of the rack to avoid air flow between the hot and cold aisles.
- D. The casters and feet should be larger to avoid a too heavy point load on the floor tile.
Answer: D
Explanation:
The casters and feet under the rack are used to support the weight of the rack and its equipment, and to allow the rack to be moved if needed. However, the casters and feet should also be designed to avoid putting too much pressure on the floor tile, especially if the data centre uses a raised floor system. A too heavy point load on the floor tile can cause the tile to crack, deform, or collapse, which can damage the rack, the equipment, and the underlying infrastructure. To prevent this, the casters and feet should be larger, so that they can distribute the weight over a larger area and reduce the point load. The casters and feet should also be compatible with the floor type and the load rating of the floor tile.

NEW QUESTION # 19
Escape route signage should be placed where?
- A. Only at the main entrance of the data centre building
- B. At every door including riser doors, doors of storage closets etc.
- C. Only at emergency escape doors
- D. At every door providing a pathway
Answer: D
Explanation:
Escape route signage should be placed at every door providing a pathway to the exit or the assembly area, according to the CDCP Preparation Guide1 and the EU Safety/Health Signs Directive2. Escape route signage is used to guide the occupants of the data centre fromwherever they are in the building, via a place of relative safety (the escape route), to the place of ultimate safety (the assembly area). Escape route signage should not be limited to only emergency escape doors or the main entrance of the data centre building, as these may not be accessible or visible from all locations. Escape route signage should also not include doors that do not lead to the exit or the assembly area, such as riser doors, doors of storage closets, or doors of other rooms, as these may confuse or mislead the occupants. Escape route signage should be placed at every door that provides a pathway to the exit or the assembly area, and should indicate the direction and distance of the escape route using pictograms, arrows, and words. Escape route signage should also be designed and installed in accordance with the relevant standards and codes, such as BS 5499 and ISO 7010.

NEW QUESTION # 20
An optical fiber cable comes with the specifications 50/125 um.
What do the numbers represent?
- A. The first number represents the required distance to single-phase power cabling; the second number represents the required distance to three-phase cabling.
- B. The first number represents the distance for a 10 Gb/s connection; the second number represents the distance for a 1 Gb/s connection.
- C. The first number represents the diameter of the core; the second number represents the diameter of the cladding in microns.
- D. The first number represents the diameter of the core; the second number represents the actual diameter cable including the buffer and jacket.
Answer: C
Explanation:
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.

NEW QUESTION # 21
What needs to be installed in the battery room when using Lithium-ion batteries?
- A. High capacity air-conditioning equipment since Lithium-ion batteries are sensitive to high temperatures, which can reduce their lifetime.
- B. A proper supply of distilled water.
- C. A proper ventilation system since Lithium-ion batteries produce highly flammable Hydrogen gas during charging.
- D. A battery management system to monitor and prevent unsafe temperatures during charging/discharging.
Answer: D
Explanation:
According to the EPI Data Centre Training Framework, lithium-ion batteries are becoming more popular in data centres due to their higher energy density, longer lifespan, and lower maintenance costs compared to lead-acid batteries1. However, lithium-ion batteries also have some drawbacks, such as higher initial cost, stricter safety requirements, and potential thermal runaway risks1. Therefore, a battery management system (BMS) is essential to monitor and control the voltage, current, temperature, and state of charge of each battery cell or module, and to prevent overcharging, over-discharging, or overheating23. A BMS can also communicate with the UPS system and provide information on the battery status, performance, and health2.

NEW QUESTION # 22
What should be considered when implementing hot- or cold-aisle containment in an existing computer room?
- A. Equipment will get too hot at the rear (back) of the rack potentially resulting in more ICT hardware failures.
- B. It creates potential issues with the existing fire suppression system(s).
- C. It will be more difficult to install power and network cabling in the contained area.
- D. The delta-T of the equipment will increase too much causing reliability issues.
Answer: B
Explanation:
Hot- or cold-aisle containment is a strategy to improve the cooling efficiency and reduce the energy consumption of data centers by isolating the hot exhaust air from the cold supply air. However, implementing this strategy in an existing computer room may create potential issues with the existing fire suppression system(s), such as:
*The containment barriers may interfere with the distribution and activation of the fire suppression agents, such as water, gas, or aerosol, and reduce their effectiveness in extinguishing a fire.
*The containment barriers may create pockets of high temperature and pressure that could damage the equipment or the containment structure itself in the event of a fire.
*The containment barriers may obstruct the access and visibility of the fire detection and alarm devices, such as smoke detectors, heat sensors, or manual call points, and delay the response time of the fire suppression system(s).
*The containment barriers may violate the local fire codes and regulations that specify the minimum clearance and ventilation requirements for the data center.
Therefore, when implementing hot- or cold-aisle containment in an existing computer room, it is important to consider the impact on the existing fire suppression system(s) and take appropriate measures to ensure the safety and compliance of the data center, such as:
*Consulting with the fire authorities and the fire suppression system vendor to assess the compatibility and suitability of the containment solution with the existing fire suppression system(s).
*Modifying or upgrading the existing fire suppression system(s) to accommodate the containment solution, such as relocating or adding fire suppression devices, adjusting the discharge rate and pressure, or installing a secondary fire suppression system within the contained area.
*Installing fire-rated containment barriers that can withstand high temperatures and resist the spread of fire and smoke, and that have self-closing or automatic release mechanisms in case of a fire.
*Installing fire detection and alarm devices within the contained area and ensuring their proper integration and communication with the existing fire suppression system(s).
*Conducting regular testing and maintenance of the fire suppression system(s) and the containment solution to ensure their functionality and reliability.

NEW QUESTION # 23
The three elements of the fire triangle are,and. (Choose three.)
- A. Heat
- B. Water
- C. Earth
- D. Fuel
- E. Oxygen
Answer: A,D,E
Explanation:
The fire triangle is a simple model that illustrates the three elements that a fire needs to ignite and sustain:
oxygen, heat, and fuel. Oxygen is the oxidizing agent that enables the combustion reaction, heat is the energy source that raises the temperature of the fuel to its ignition point, and fuel is the material that reacts with oxygen and releases heat and light. Removing any one of these elements can extinguish a fire. For example, water can reduce the heat and the oxygen, sand or soil can smother the fuel and the oxygen, and fire extinguishers can displace the oxygen or lower the temperature.

NEW QUESTION # 25
is the degree to which a system or component is operational and accessibility when required for use.
- A. Reliability
- B. Agility
- C. Scalability
- D. Availability
Answer: D
Explanation:
Availability is the degree to which a system, product or component is operational and accessible when required for use. It is one of the attributes of reliability, which is the ability of a system or component to perform its required functions under stated conditions for a specified period of time. Availability can be calculated as the ratio of the expected value of the uptime (the time when the system is functional) to the total time (uptime plus downtime) of a system or component. Availability can also be influenced by factors such as maintainability, fault tolerance, redundancy, diagnostics, and logistics.
References: EPI Data Centre Professional (CDCP®) Preparation Guide, page 8; Availability - Wikipedia; Reliability - ISO 25000.
NEW QUESTION # 26
What is the minimum clearance space required below water sprinkler heads and nozzles of gas-based fire suppression systems?
- A. 46 cm / 18 inches
- B. 60 cm / 24 inches
- C. 64 cm / 25 inches
- D. 120 cm / 47 inches
Answer: A
Explanation:
The minimum clearance space required below water sprinkler heads and nozzles of gas-based fire suppression systems is 46 cm / 18 inches, according to the CDCP Preparation Guide1 and OSHA regulation 29 CFR
1910.159 (10)2. This clearance space is necessary to ensure that the sprinkler spray or gas discharge can reach the fire and cover the protected area effectively. Any material or obstruction below this clearance space can interfere with the sprinkler or gas distribution and reduce the fire suppression performance. Therefore, building owners and managers should ensure that all storage and objects in the data centre are kept below this clearance space, and that the clearance space is maintained at all times.

NEW QUESTION # 27
Does shielded twisted pair network cabling provide protection against EMF from power cables?
- A. Yes, as the shielding for twisted pair network cabling is specifically design for low frequency EMF protection.
- B. No, the shielding for twisted pair network cabling is for physical protection against vandalism and accidental cutting of the cable.
- C. No, the shielding is designed for alien cross-talk between network cables, it provides no or little protection against low frequency EMF.
- D. Yes, but only if the power cable is placed in a tre-foil cable arrangement.
Answer: C
Explanation:
Shielded twisted pair cables (STP) are Ethernet cables that feature additional protection against electromagnetic interference from external sources, such as radio waves, microwaves, or other network cables. This is achieved by wrapping each pair of wires with a conductive shield, usually made of foil or braided wire, and then enclosing the entire cable with another shield layer. However, this shielding is not effective against low frequency electromagnetic fields (EMF) from power cables, which can induce currents and voltages in the network cables and cause signal distortion or data loss. Low frequency EMF can only be reduced by increasing the distance between the power and network cables, or by using a tre-foil cable arrangement, which is a special configuration of three power cables twisted together to cancel out the magnetic fields they generate.
