When a systems administrator needs to access a hypervisor and the default RDP port (3389) is blocked by company policy, the administrator can use an alternative method. One common alternative is using SSH:

Port 22: This is the default port for SSH (Secure Shell), which is commonly used for secure remote access to servers and hypervisors, especially in Unix/Linux environments.

Port 23: This is the default port for Telnet, which is an unsecured protocol and generally not recommended for remote access due to security concerns.

Port 80: This is the default port for HTTP, used for web traffic, not remote access.

Port 3090: This is not a standard port for remote access protocols.

Using SSH (port 22) is a secure and widely accepted method for remote management of servers and hypervisors.

The most likely reason that the system is not utilizing all the available RAM is that it is running a 32-bit OS. A 32-bit OS can only address up to 4GB of RAM, and some of that is reserved for hardware and system use1. Therefore, even if the technician installed 8GB of RAM, the system can only use around 3.5GB of usable RAM. To use the full 8GB of RAM, the technician would need to install a 64-bit OS, which can address much more memory2. The system missing updates, the system’s memory failing, or the system requiring BIOS updates are not likely to cause this issue.

Shredding is the most effective method to securely dispose of data stored on optical discs12

After implementing a change authorized by the change advisory board (CAB), the technician should document the date and time of change as part of the post-implementation review. This helps to track the change history, verify the success of the change, and identify any issues or incidents caused by the change1. Documenting the purpose of the change, the risk level, and the findings of the sandbox test are all part of the pre-implementation activities that should be done before submitting the change request to the CAB2.

The type of backup that should be completed FIRST after installing a new backup and recovery system is a full backup. This is because a full backup is a complete backup of all data and is the foundation for all other backups. After a full backup is completed, other types of backups, such as differential and incremental backups, can be performed.

Badge readers are used to implement secure physical access to a data center. They are used to read the identification information on an employee’s badge and grant access to the data center if the employee is authorized2.

 This system requires individuals to have an access badge that contains their identification information or a unique code that can be scanned by a reader. After the badge is scanned, the system compares the information on the badge with the authorized personnel database to authenticate if the individual has the required clearance to enter that area. The other options listed, such as a geofence, alarm system, or motion sensor are security measures that may be used in conjunction with badge readers, but do not provide identification and authentication features.

A netbook with a web-based, proprietary operating system is most likely running Chrome OS. Chrome OS is a web-based operating system developed by Google that is designed to work with web applications and cloud storage. It is optimized for netbooks and other low-power devices and is designed to be fast, secure, and easy to use.

The incident handler should clone any impacted hard drives to preserve evidence for possible litigation1
