CompTIA Updated SK0-005 Exam Questions and Answers by giovanni

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

SSH (Secure Shell) is a protocol that would most likely be implemented to encrypt data in transit for remote administration. SSH provides secure communication between two devices over an unsecured network by using public-key cryptography and symmetric encryption. SSH can be used to remotely execute commands, transfer files, or tunnel other protocols. Telnet, TFTP, and rlogin are protocols that do not encrypt data in transit and are considered insecure for remote administration. References: [CompTIA Server+ Certification Exam Objectives], Domain 2.0: Networking, Objective 2.4: Given a scenario involving network security/access methods, implement an appropriate solution.

GPT (GUID Partition Table) is a partitioning scheme that allows creating partitions on large hard drives (more than 2 TB). It supports up to 128 partitions per drive and uses 64-bit addresses to locate them. However, GPT is not compatible with older versions of Windows, such as Windows XP or Windows Server 2003, which use MBR (Master Boot Record) as the partitioning scheme. If a disk uses GPT, it may not be recognized or accessible by an older Windows server. Verified References: [GPT], [MBR]

The given output in the image indicates that the file is present, but the permissions may not allow it to be read. The output indicates '-rw-------', which means that the file is set to be readable and writable by the owner only, with no permissions for group or others. To allow the file to be read by users other than the owner, the file's permissions will need to be changed. The chmod (change mode) command is used to change the file's permissions in Linux. For example, chmod 644 file would change the permissions of the file to be readable by everyone and writable by the owner, which is typically what's required for a file server. It is always recommended to apply the least permissive settings that still allow the required operation to maintain security.
