CompTIA Server+ Certification SK0-005 Exam Practice Test

Answer : B

The company should also implement MFA on all the servers with encrypted data as a data loss prevention method. MFA stands for multi-factor authentication, which is a method of verifying a user's identity by requiring two or more pieces of evidence, such as something they know (e.g., a password), something they have (e.g., a token), or something they are (e.g., a fingerprint). MFA adds an extra layer of security to prevent unauthorized access to sensitive data, even if the user's password is compromised or stolen. Encrypting the hard drives on the servers protects the data from being read or copied if the drives are physically removed or stolen, but it does not prevent unauthorized access to the data if the user's credentials are valid.

Answer : B

A purple screen with white letters on an ESX server indicates a kernel panic, which is a fatal error thatcauses the system to crash and stop functioning3.The first troubleshooting step that an administrator should perform is to review the log files, which may contain information about the cause of the error, such as hardware failures, software bugs, or configuration issues4. Checking the power supplies (A) may not be relevant, as the system is still displaying a screen.Reinstalling the ESX server or reseating the processors (D) are drastic measures that may result in data loss or further damage, and should only be attempted after ruling out other possible causes.

Answer : D

A Fibre Channel SAN solution is a type of storage area network (SAN) that uses high-speed optical fiber cables to connect servers and storage devices.A SAN allows for hosting data without impacting performance when the data is accessed in real time by multiple users, as it provides fast data transfer rates, low latency, high availability, and scalability12. A local external hard drive (A) would not be suitable for multiple users, as it would limit the accessibility and security of the data. Adding extra memory to the server (B) would not solve the problem of data access performance, as it would not increase the bandwidth or reduce the congestion of the network.Compressing the data would not improve the performance either, as it would add extraoverhead and complexity to the data processing and retrieval.

Answer : A, C, F

After removing the virus from the server, the administrator should perform the following actions to mitigate the issue from reoccurring and to maintain high availability:

Run a vulnerability scanner on the server to identify any other potential weaknesses or exposures that could be exploited by attackers.

Patch the vulnerability that allowed the virus to infect the server in the first place, using the latest updates from the database software vendor or a trusted source.

Update the antivirus software on the server to ensure it has the most recent virus definitions and can detect and prevent future infections. The other options are either unnecessary or counterproductive for this scenario. Repartitioning the hard drive, reformatting the OS, removing the database software, or air gapping the server from the network would cause downtime and data loss, while enabling a host firewall would not prevent a virus infection from within the network.Reference:CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.2: Given a scenario involving a security threat/vulnerability/risk, implement appropriate mitigation techniques.

Answer : B

The technician should use port 22 to configure a server that requires secure remote access. Port 22 is the default port for Secure Shell (SSH), which is a protocol that allows secure remote login and command execution over a network connection using a command-line interface (CLI). SSH encrypts both the authentication and data transmission between the client and the server, preventing eavesdropping, tampering, or spoofing. SSH can be used to perform various tasks on a server remotely, such as configuration, administration, maintenance, troubleshooting, etc.

Answer : B

The /etc/fstab file contains the information about the file systems that are mounted automatically at boot time or on demand. The entry nfsserver:/home /home nfs defaults 0 0 indicates that the /home directory on the local server is mounted from the /home directory on a remote server called nfsserver using the NFS protocol. However, the df -h /home command shows that the /home directory is actually mounted from a local partition /dev/sda2, which may not contain the user's files. This means that the NFS mount failed or was overridden by another mount. To resolve the issue, the technician should attempt to unmount the local partition using umount nfsserver:/home, which will detach the /home directory from /dev/sda2.Then, the technician should try to mount the NFS share again using mount /home, which will attach the /home directory to nfsserver:/home according to the /etc/fstab entry12. Creating a new directory (A) or removing an existing one would not help, as they would not affect the mount point.Mounting /home (D) without unmounting it first would not work, asit would result in an error that the mount point is busy3.

Answer : C

A tower server is a type of server architecture that is best suited to minimize cost when deploying a single server to monitor and record the security cameras at a remote site. A tower server is a standalone server that has a similar form factor and design as a desktop computer. It does not require any special mounting equipment or rack space and can be placed on or under a desk or table. A tower server is suitable for small businesses or remote offices that need only one or few servers for basic tasks such as file sharing, print serving, or security monitoring. A tower server is usually cheaper and easier to maintain than other types of servers, but it may have lower performance, scalability, and redundancy features. A virtual server is a type of server architecture that involves creating and running one or more virtual machines on a physical host using a hypervisor such as Hyper-V or VMware. A virtual server can reduce hardware costs and improve flexibility and efficiency, but it requires additional software licenses and management tools. A blade server is a type of server architecture that involves inserting multiple thin servers called blades into a chassis that provides power, cooling, network, and management features. A blade server can improve performance, density, and scalability, but it requires more initial investment and specialized equipment. A rack mount server is a type of server architecture that involves mounting one or more servers into standardized frames called racks that provide power, cooling, network, and security features
