Which of the following tools will analyze network logs in real time to report on suspicious log events?
Correct Answer:
C
SIEM is the tool that will analyze network logs in real time to report on suspicious log events. SIEM stands for Security Information and Event Management, which is a software solution that collects, analyzes, and correlates log data from various sources, such as servers, firewalls, routers, antivirus software, etc. SIEM can detect anomalies, patterns, trends, and threats in the log data and generate alerts or reports for security monitoring and incident response. SIEM can also provide historical analysis and compliance reporting for audit purposes.

When configuring networking on a VM, which of the following methods would allow multiple VMs to share the same host IP address?
Correct Answer:
B
The method that would allow multiple VMs to share the same host IP address is NAT. NAT (Network Address Translation) is a technique that allows multiple devices to use a single public IP address by mapping their private IP addresses to different port numbers. NAT can be used for VM networking to enable multiple VMs on the same host to access the internet or other networks using the host’s IP address. NAT can also provide security benefits by hiding the VMs’ private IP addresses from external networks.

A technician recently replaced a NIC that was not functioning. Since then, no device driver is found when starting the server, and the network card is not functioning. Which of the following should the technician check first?
Correct Answer:
C
The technician should check the hardware compatibility list (HCL) first to see if the new NIC is supported by the server’s operating system. The HCL is a list of hardware devices that have been tested and verified to work with a specific operating system. If the NIC is not on the HCL, it means that there is no device driver available or compatible for it, and the NIC will not function properly.

An administrator is configuring a server that will host a high-performance financial application. Which of the following disk types will serve this purpose?
Correct Answer:
A
The best disk type for a high-performance financial application is a SAS SSD. A SAS SSD (Serial Attached SCSI Solid State Drive) is a type of storage device that uses flash memory chips to store data and has a SAS interface to connect to a server or a storage array. A SAS SSD offers high speed, low latency, high reliability, and high durability compared to other types of disks, such as SATA SSDs, SAS HDDs, or SATA HDDs. A SAS SSD can handle high I/O workloads and deliver consistent performance for applications that require fast data access and processing.

Network connectivity to a server was lost when it was pulled from the rack during maintenance. Which of the following should the server administrator use to prevent this situation in the future?
Correct Answer:
A
The server administrator should use cable management to prevent network connectivity loss when pulling a server from the rack during maintenance. Cablemanagement is a practice of organizing and securing the cables that connect various devices and components in a system. Cable management can help improve airflow, reduce clutter, prevent tangling, and avoid accidental disconnection or damage of cables. Cable management can be done using various tools and techniques, such as cable ties, cable trays, cable labels, cable organizers, or cable ducts.
