Question#1

After a technician upgrades the firmware on a database server that is connected to two external storage arrays, the server prompts the technician to configure RAID. The technician knows the server had several configured RAID sets and thinks the firmware upgrade cleared the RAID configurations.
Which of the following should the technician do to troubleshoot this issue?

A. Power cycle the storage arrays and rescan RAID on the server.
B. Boot the OS into recovery mode and rescan the disks.
C. Restore the default RAID configuration and reboot.
D. Perform a rescan on the server's RAID controller.

Explanation:
A rescan on the server’s RAID controller is a possible troubleshooting step to detect the existing RAID configurations on the connected storage arrays. A firmware upgrade may cause the RAID controller to lose the RAID metadata or settings, and a rescan may restore them. A rescan is preferable to restoring the default RAID configuration, as the latter may erase the existing data on the arrays. Power cycling the storage arrays or booting the OS into recovery mode may not help if the RAID controller does not recognize the RAID sets.

Question#2

A software developer is unable to reach an internal website. The developer's attempt to ping the FQDN returns the following IP address: 104.18.17.32.
Which of the following is the most likely reason for this result?

A. The NIC is set to DHC
B. The default gateway is misconfigured.
C. The primary DNS server is 8.8.8.8.
D. There is a manual entry in the hosts file.

Explanation:
The most likely reason for this result is that there is a manual entry in the hosts file that maps the FQDN to an incorrect IP address (104.18.17.32). The hosts file is a text file that contains mappings of hostnames or domain names to IP addresses, which are used by the operating system to resolve names before querying DNS servers on the network or internet. The hosts file can be used to override DNS settings or block access to certain websites by redirecting them to different IP addresses, such as localhost (127.O.O.l) or invalid addresses (O.O.O.O). If there is a manual entry in the hosts file that conflicts with DNS records, it can cause name resolution errors or connectivity issues.

Question#3

A junior administrator needs to configure a single RAID 5 volume out of four 200GB drives attached to the server using the maximum possible capacity. Upon completion, the server reports that all drives were used, and the approximate volume size is 400GB.
Which of the following BEST describes the result of this configuration?

A. RAID 0 was configured by mistake.
B. RAID 5 was configured properly.
C. JBOD was configured by mistake.
D. RAID 10 was configured by mistake.

Explanation:
The output of the configuration shows that RAID 5 was configured properly using four 200GB drives.
The approximate volume size of 400GB is correct, since RAID 5 uses one disk for parity and the rest for data. Therefore, the usable storage capacity is three-fourths of the total capacity, which is 600GB out of 800GB. The other RAID levels given would result in different volume sizes: RAID 0 would result in 800GB, RAID 1 would result in 200GB, and JBOD would result in an error since it does not support multiple drives in a single volume.

Question#4

A company is implementing a check-in desk to heighten physical security.
Which of the following access controls would be the most appropriate to facilitate this implementation?

A. Security guards
B. Security cameras
C. Bollards
D. An access control vestibule

Explanation:
An access control vestibule, or mantrap, is a type of physical access control that provides a space between two sets of interlocking doors. It is designed to prevent unauthorized individuals from following authorized individuals into facilities with controlled access, such as a check-in desk. The vestibule can be configured to limit the number of individuals who enter the controlled area and to verify their authorization for physical access1. The other options are incorrect because they are not as effective as an access control vestibule in facilitating the implementation of a check-in
desk. Security guards, security cameras, and bollards are useful for monitoring, deterring, or preventing unauthorized access, but they do not provide the same level of control and verification as an access control vestibule

Question#5

A systems administrator needs to create a data volume out of four disks with the MOST redundancy.
Which of the following is the BEST solution?

A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 6

Explanation:
RAID 6 is a type of RAID level that uses two parity blocks to provide fault tolerance and redundancy for data storage. RAID 6 can withstand the failure of up to two disks in the array without losing any data. RAID 6 requires a minimum of four disks to operate, and it distributes the data and parity blocks across all the disks in the array. RAID 6 has a high write penalty, which means that it takes more time and resources to write data to the disks than to read data from them. However, RAID 6 offers a high level of data protection and reliability, which makes it suitable for applications that require high availability and durability1.
RAID 1 provides redundancy and fault tolerance by mirroring the data from one disk to another disk. RAID 1 offers high read performance and data security, but it has low capacity and write performance. RAID 1 requires a minimum of two disks to operate, and it can only tolerate the failure of one disk in the array. If more than one disk fails, all the data in the array is lost2.
RAID 5 provides redundancy and fault tolerance by using one parity block to store information that can be used to reconstruct the data in case of a disk failure. RAID 5 requires a minimum of three disks to operate, and it distributes the data and parity blocks across all the disks in the array. RAID 5 offers a balance between performance, capacity, and data protection, but it can only tolerate the failure of one disk in the array. If more than one disk fails, all the data in the array is lost2.
Therefore, among these options, RAID 6 is the best solution for creating a data volume out of four disks with the most redundancy.
