A server administrator has connected a new server to the network. During testing, the administrator discovers the server is not reachable via server but can be accessed by IP address. Which of the following steps should the server administrator take NEXT? (Select TWO).
Correct Answer:
CD
If the server is not reachable by name but can be accessed by IP address, it means that there is a problem with name resolution. The hosts file and the DNS server are both responsible for mapping hostnames to IP addresses. Therefore, the server administrator should check these two files for any errors or inconsistencies that might prevent the server from being resolved by name.

Which of the following backup types only records changes to the data blocks on a virtual machine?
Correct Answer:
B
The backup type that only records changes to the data blocks on a virtual machine is snapshot. A snapshot is a point-in-time copy of a virtual machine (VM) that captures the state and data of the VM at a specific moment. A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the VM after the snapshot was taken. A snapshot can be used to restore the VM to its previous state in case of data loss or corruption.
An administrator is working on improving the security of a new domain controller. A report indicates several open ports on the server. Which of the following ports should the administrator disable?
Correct Answer:
D
The port that should be disabled on the firewall is port 3389. Port 3389 is used by Remote Desktop Protocol (RDP), which is a protocol that allows remote access and controlof a Windows system through a graphical user interface. RDP can pose a security risk if it is not properly configured or secured, as it can expose the system to unauthorized or malicious access from external sources. Therefore, port 3389 should be disabled on the firewall unless it is needed for legitimate purposes.

A server administrator must respond to tickets within a certain amount of time. The server administrator needs to adhere to the:
Correct Answer:
D
The server administrator needs to adhere to the Service Level Agreement (SLA) when responding to tickets within a certain amount of time. An SLA is a contract between a service provider and a customer that defines the quality, availability, and responsibilities of the service. An SLA may specify the response time for tickets, as well as other metrics such as uptime, performance, security, and backup frequency.Reference: https://www.ibm.com/cloud/learn/service-level-agreements
A server technician notices a server is very low on disk space. Upon inspecting the disk utilization, the technician discovers server logs are taxing up a large amount of space. There is no central log server. Which of the following would help free up disk space?
Correct Answer:
B
Log rotation is a process that periodically renames, compresses, and deletes old log files to free up disk space and keep log files manageable. Log rotation can be configured using tools such as logrotate or cron on Linux systems, or using Windows Task Scheduler or PowerShell scripts on Windows systems. Log rotation can also help with log analysis and troubleshooting by making it easier to find relevant information in smaller and more recent log files.
