A technician needs maximum power redundancy while configuring a new server rack. Which of the following should be specified? (Select two).
Correct Answer:
AF
Separate circuits and multiple UPSs can provide fail-safe power redundancy for a server rack. Separate circuits mean that the server rack is connected to two or more independent power sources, such as different utility lines or generators. This can prevent a single point of failure in the power supply, as if one circuit goes down, the other circuit can still provide power to the server rack1. Multiple UPSs mean that the server rack has two or more uninterruptible power supplies, which are devices that provide backup power and surge protection in case of a power outage or fluctuation. Multiple UPSs can be connected to separate circuits, or to different outlets on the same circuit, to increase the reliability and availability of power for the server rack23.
Which of the following DR testing scenarios is described as verbally walking through each step of the DR plan in the context of a meeting?
Correct Answer:
D
The DR testing scenario that is described as verbally walking through each step of the DR plan in the context of a meeting is tabletop. A tabletop test is a type of disaster recovery (DR) test that involves discussing and reviewing the DR plan with key stakeholders and participants in a simulated scenario. A tabletop test does not involve any actual execution of the DR plan or any disruption of the normal operations. A tabletop test can help identify gaps, issues, or inconsistencies in the DR plan and improve communication and coordination among the DR team members.
Which of the following BEST describes a warm site?
Correct Answer:
D
A warm site is a type of disaster recovery site that has some pre-installed hardware, software, and network connections, but not as much as a hot site. A warm site also has some backup data, but not as current as a hot site. A warm site requires some time and effort to become fully operational in the event of a disaster. A hot site is a disaster recovery site that has all infrastructure and live data, and can take over the primary site’s operations immediately. A cold site is a disaster recovery site that has no infrastructure or data, and requires significant time and resources to set up. References:

A technician is connecting a Linux server to a share on a NAS. Which of the following is the MOST appropriate native protocol to use for this task?
Correct Answer:
D
The most appropriate native protocol to use for connecting a Linux server to a share on a NAS is NFS. NFS (Network File System) is a protocol that allows file sharing and remote access over a network. NFS is designed for Unix-like operating systems, suchas Linux, and supports features such as symbolic links, hard links, file locking, and file permissions. NFS uses mount points to attach remote file systems to local file systems, making them appear as if they are part of the local file system. NFS can provide fast and reliable access to files stored on a NAS (Network Attached Storage), which is a device that provides centralized storage for network devices.
The Chief Information Officer of a data center is concerned that transmissions from the building can be detected from the outside. Which of the
following would resolve this concern? (Select TWO).
Correct Answer:
CD
Signal blocking is a technique that prevents or reduces the transmission of electromagnetic signals from a building to the outside. Signal blocking can be achieved by using materials that absorb, reflect, or scatter the signals, such as metal, concrete, or mesh. Signal blocking can protect the data center from eavesdropping, interference, or jamming by unauthorized parties1.
Camouflage is a technique that disguises or conceals the appearance of a building to make
it less noticeable or identifiable from the outside. Camouflage can be achieved by using colors, patterns, shapes, or vegetation that blend in with the surrounding environment. Camouflage can protect the data center from detection, reconnaissance, or targeting by hostile parties
