The Chief Information Officer (CIO) of a datacenter is concerned that transmissions from the building can be detected from the outside. Which of the following would resolve this concern? (Choose two.)
Correct Answer:
CE
The best solutions to resolve the concern of transmissions from the building being detected from outside are signal blocking and reflective glass. Signal blocking is a method of preventing or interfering with electromagnetic signals from escaping or entering a certain area. Signal blocking can be achieved by using various materials or devices that create physical barriers or generate noise or jamming signals. Signal blocking can protect data transmissions from being intercepted or eavesdropped by unauthorized parties. Reflective glass is a type of glass that has a coating or film that reflects light and heat. Reflective glass can reduce glare and solar radiation, as well as prevent visual observation from outside. Reflective glass can enhance privacy and security for datacenter operations.
An administrator is alerted to a hardware failure in a mission-critical server. The alert states that two drives have failed. The administrator notes the drives are in different RAID 1 arrays, and both are hot-swappable. Which of the following steps will be the MOST efficient?
Correct Answer:
C
Since both drives are in different RAID 1 arrays and both are hot-swappable, the most efficient step is to replace both failed drives at the same time. This can minimize the downtime and avoid unnecessary reboots. RAID 1 provides mirroring, which means that data is duplicated on both drives in the array. Therefore, replacing one drive will not affect the data on the other drive or the functionality of the array.References:https://en.wikipedia.org/wiki/Standard_RAID_levels#RAID_1
A technician set up a new multifunction printer. After adding the printer to the print server, the technician configured the printer on each user's machine. Several days later, users reported that they were no longer able to print, but scanning to email worked. Which of the following is most likely causing this issue?
Correct Answer:
D
The most likely cause of this issue is that the printer had DHCP enabled, which changed its IP address after adding it to the print server and configuring it on each user’s machine. DHCP (Dynamic Host Configuration Protocol) is a network protocol that assigns IP addresses and other network configuration parameters to devices automatically, without manual intervention. DHCP can simplify network management and avoid IP conflicts, but it can also cause problems if the devices are not configured to use static or reserved IP addresses. If the printer had DHCP enabled, it might have received a different IP address from the DHCP server after rebooting or reconnecting to the network, which would make it unreachable by the print server and the users’ machines that were configured with the previous IP address. Scanning to email would still work, as it does not depend on the print server or the users’ machines, but on the printer’s SMTP settings and internet connection.

A server administrator noticesthe/var/log/audit/audit.logfileon a Linux server is rotating loo frequently. The administrator would like to decrease the number of times the leg rotates without losing any of the information in the logs. Which of the following should the administrator configure?
Correct Answer:
A
The audit.log file is a file that records security-related events on a Linux server, such as user login, file access, and system commands. The logrotate utility is a tool that rotates, compresses, and deletes old log files based on certain criteria, such as size, time, or frequency. To decrease the number of times the log rotates without losing any information, the administrator should increase the audit.log file size in the appropriate configuration file, such as /etc/logrotate.conf or /etc/logrotate.d/auditd.

A technician is installing a variety of servers in a rack. Which of the following is the BEST course of action for the technician to take while loading the rack?
Correct Answer:
B
The technician should install the heaviest server at the bottom of the rack to load the rack properly. Installing the heaviest server at the bottom of the rack helps to balance the weight distribution and prevent the rack from tipping over or collapsing. Installing the heaviest server at the bottom of the rack also makes it easier to access and service the server without lifting or moving it. Installing the heaviest server at any other position in the rack could create instability and safety hazards.
