NEW QUESTION # 212
Which of the following BEST describes overprovisioning in a virtual server environment?
- A. Committing more virtual resources to virtual machines than there are physical resources present
- B. Allowing a virtual machine to utilize more resources than are allocated to it based on the server load
- C. Ensuring there are enough physical resources to sustain the complete virtual environment in the event of a host failure
- D. Installing more physical hardware than is necessary to run the virtual environment to allow for future expansion
Answer: A
Explanation:
This is the best definition of overprovisioning in a virtual server environment because it means allocating more CPU, memory, disk, or network resources to the virtual machines than what is actually available on the physical host. This can lead to performance issues and resource contention. Reference: https://www.hpe.com/us/en/insights/articles/10-virtualization-mistakes-everyone-makes-1808.html
NEW QUESTION # 213
An administrator discovers a Bash script file has the following permissions set in octal notation;
777
Which of the following is the MOST appropriate command to ensure only the root user can modify and execute the script?
- A. chmod u=rwx
- B. chmod go-rw>:
- C. chmod g-rwx
- D. chmod u+wx
Answer: B
Explanation:
chmod is a command-line tool that changes the permissions of files and directories in Linux and Unix systems. chmod go-rwx means to remove read, write, and execute permissions for group and other users from a file or directory. This can ensure only the root user can modify and execute the script, since root user has full access to all files and directories regardless of their permissions.

NEW QUESTION # 214
A storage administrator is investigating an issue with a failed hard drive. A technician replaced the drive in the storage array; however, there is still an issue with the logical volume. Which of the following best describes the NEXT step that should be completed to restore the volume?
- A. Replace the volume
- B. Format the volume
- C. Rebuild the volume
- D. Initialize the volume
Answer: C
Explanation:
The administrator should rebuild the volume to restore it after replacing the failed hard drive. A volume is a logical unit of storage that can span across multiple physical disks. A volume can be configured with different levels of RAID (Redundant Array of Independent Disks) to provide fault tolerance and performance enhancement. When a hard drive in a RAID volume fails, the data on that drive can be reconstructed from the remaining drives using parity or mirroring techniques. However, this process requires a new hard drive to replace the failed one and a rebuild operation to copy the data from the existing drives to the new one. Rebuilding a volume can take a long time depending on the size and speed of the drives and the RAID level.
NEW QUESTION # 215
A systems administrator has been alerted to a zero-day vulnerability that is impacting a service enabled on a server OS. Which of the following would work BEST to limit an attacker from exploiting this vulnerability?
- A. Enabling antivirus protection
- B. Installing the latest patches
- C. Enabling a NIDS
- D. Closing open ports
Answer: D
Explanation:
A zero-day (or 0-day) vulnerability is a software vulnerability that is discovered by attackers before the vendor has become aware of it. By definition, no patch exists for zero day vulnerabilities and user systems have no defenses in place, making attacks highly likely to succeed. One of the most common recovery methods for a zero-day attacks is to physically (or via a network-based firewall) remove all access from anyone who would have the ability to exploit it. Blocking the ports used for Remote PowerShell can limit these attacks.
NEW QUESTION # 216
An administrator is troubleshooting an application performance issue on a virtual server with two vCPUs. The application performance logs indicate CPU contention. The administrator adds more vCPU cores to the VM, yet the issue persists. Which of the following is the most likely reason for this issue?
- A. The application is single-threaded.
- B. The server has high disk latency.
- C. The application cannot be virtualized.
- D. The server has high page utilization.
Answer: A
Explanation:
A single-threaded application is an application that can only execute one task or process at a time. A single-threaded application can only utilize one CPU core, regardless of how many cores are available or assigned to the virtual machine. Therefore, adding more vCPU cores to the VM will not improve the performance of the application, as it will still be limited by the speed and capacity of one core12.
To troubleshoot this issue, the administrator should check if the application is single-threaded or multi-threaded. This can be done by using tools such as Task Manager, Performance Monitor, or Process Explorer on Windows, or top, htop, or ps on Linux34. If the application is single-threaded, the administrator should consider the following options:
Reduce the number of vCPU cores on the VM to match the number of threads that the application can use. This can help avoid CPU contention and co-stop issues that may arise from having too many vCPUs relative to the number of physical cores on the host5.
Upgrade the physical CPU on the host to a faster or newer model that can provide higher clock speed and performance for the single core that the application uses.
Optimize the application code or configuration to make it more efficient or multi-threaded, if possible. This can help the application take advantage of multiple cores and improve its performance.
NEW QUESTION # 217
A server administrator mounted a new hard disk on a Linux system with a mount point of /newdisk. It was later determined that users were unable to create directories or files on the new mount point. Which of the following commands would successfully mount the drive with the required parameters?
- A. mount -o remount, rw /newdisk
- B. net use /newdisk
- C. mount -a
- D. echo /newdisk >> /etc/fstab
Answer: A
Explanation:
The administrator should use the command mount -o remount,rw /newdisk to successfully mount the drive with the required parameters. The mount command is used to mount file systems on Linux systems. The -o option specifies options for mounting file systems. The remount option re-mounts an already mounted file system with different options. The rw option mounts a file system with read-write permissions. In this case, /newdisk is a mount point for a new hard disk that was mounted with read-only permissions by default. To allow users to create directories or files on /newdisk, the administrator needs to re-mount / Reference:

A company stores extremely sensitive data on an air-gapped system.
Which of the following can be implemented to increase security against a potential insider threat?
- A. SIEM
- B. Two-person Integrity
- C. Faraday cage
- D. SSO
- E. MFA
Answer: E
Explanation:
Air-gapping is a sound security strategy - but one must acknowledge both its gaps and implications on the security products you can use. Silverfort's MFA enables you to enforce secure authentication and validate the identity of users in air-gapped networks, ensuring they are protected against identity-based attacks.
NEW QUESTION # 219
The management team has mandated the use of data-at-rest encryption on all corporate servers. Using this encryption paradigm will ensure:
- A. files stored on the server are protected against physical theft.
- B. attachments that are emailed from this server cannot be intercepted.
- C. website traffic is protected while traversing the internet.
- D. databases in use are protected from remote hackers.
Answer: A
Explanation:
Explanation
Data-at-rest encryption is a method of encrypting data while it is stored on a storage device, such as a hard drive, an SSD, or a tape library. This ensures that if the data is stolen or lost, it will be unreadable without the encryption key. Data-at-rest encryption does not protect data while it is in transit over the network, in use by the CPU or memory, or attached to an email.

Which of the following should a technician verify FIRST before decommissioning and wiping a file server?
- A. The media destruction method
- B. Asset management documentation
- C. The recycling poke?
- D. Non-utilization
Answer: D
Explanation:
The first thing that a technician should verify before decommissioning and wiping a file server is non-utilization, which means that no one is using or accessing the server or its data. This can be done by checking logs, monitoring network traffic, or contacting users or stakeholders. Non-utilization ensures that decommissioning and wiping will not cause any data loss or disruption to business operations. Verified Reference: [Server Decommissioning Checklist]

- A. Tighten the rules on the firewall
- B. Install antivirus software
- C. Patch the server OS
- D. Upgrade the application package
Answer: D
Explanation:
Explanation
The best course of action for the company is to upgrade the application package to fix the known vulnerability.
A vulnerability is a weakness or flaw in an application that can be exploited by an attacker to compromise the security or functionality of the system. Upgrading the application package means installing a newer version of the application that has patched or resolved the vulnerability. This way, the company can prevent potential attacks that may exploit the vulnerability and cause damage or loss.
NEW QUESTION # 223
A server that recently received hardware upgrades has begun to experience random BSOD conditions. Which of the following are likely causes of the issue? (Choose two.)
- A. Overallocated memory
- B. Uninitialized disk
- C. Data partition error
- D. Incorrectly seated memory
- E. Incompatible disk speed
- F. Faulty memory
Answer: D,F
Explanation:
Faulty memory and incorrectly seated memory are likely causes of the random BSOD conditions on the server. Memory is one of the most common hardware components that can cause BSOD (Blue Screen of Death) errors on Windows systems. BSOD errors occur when the system encounters a fatal error that prevents it from continuing to operate normally. Memory errors can be caused by faulty or incompatible memory modules that have physical defects or manufacturing flaws. Memory errors can also be caused by incorrectly seated memory modules that are not properly inserted or locked into the memory slots on the motherboard. This can result in loose or poor connections between the memory modules and the motherboard.
