The administrator should only allow secure traffic and DNS inquiries on the server, which means that only ports 22, 53, and 443 should be open. Port 22 is used for SSH (Secure Shell), which is a protocol that allows secure remote login and command execution over a network connection using a command-line interface (CLI). Port 53 is used for DNS (Domain Name System), which is a service that translates domain names into IP addresses and vice versa. Port 443 is used for HTTPS (Hypertext Transfer Protocol Secure), which is a secure version of HTTP that encrypts the data exchanged between a web browser and a web server.

A sniffer is a tool that captures and analyzes network traffic on a subnet or a network interface. It can help identify the source, destination, protocol, and content of the traffic and detect any anomalies or issues on the network. Verified References: [Sniffer], [Network traffic]

Explanation: To make a new drive available on a server, the administrator needs to partition the drive first.
Partitioning is a process that divides the drive into one or more logical sections that can be formatted and assigned drive letters or mount points. Partitioning can be done using tools such as Disk Management on Windows or fdisk on Linux. Creating a new disk quota would not help, as disk quotas are used to limit the amount of disk space that users or groups can use on a partition. Configuring the drive as dynamic would not help either, as dynamic disks are used to create volumes that span multiple disks or use RAID features.
Setting the compression would not help, as compression is used to reduce the size of files on a partition.

iSCSI is a protocol that allows SCSI commands to be transmitted over IP networks, enabling remote access to storage devices. iSCSI uses IP addresses to identify and communicate with the storage array, so having multiple IP addresses for the array indicates that iSCSI is being used. eSATA, USB, and FC are other types of connections that use different protocols and connectors than iSCSI.

Ahot site with private cloud backupis the most suitable for environments that requirecontinuous accessto critical data, like student data containingPII. A hot site is fully operational and ready to take over immediately in case of a disaster. Using aprivate cloudprovides more control and security, which is important when handling sensitive data like PII.
* Hot site with private cloud backup (Answer D):This ensures minimal downtime and robust security, which is critical for handling PII.
* Warm site (Options A & B):A warm site has some infrastructure ready but requires some setup before becoming operational, which introduces some delay.
* Cold site (Option C):A cold site has the least preparation and requires significant time to become operational, which would not meet the requirement for constant availability.
