Question 1

An administrator is only able to log on to a server with a local account. The server has been successfully joined to the domain and can ping other servers by IP address. Which of the following locally defined settings is MOST likely misconfigured?



Answer : C

This is the most likely misconfigured setting because DNS is the service that resolves hostnames to IP addresses and vice versa. If the DNS server is incorrect or unreachable, the administrator will not be able to log on to the server with a domain account because the server will not be able to authenticate with the domain controller.Reference:https://docs.microsoft.com/en-us/troubleshoot/windows-server/networking/dns-troubleshooting


Question 2

The Chief Information Officer (CIO) of a datacenter is concerned that transmissions from the building can be detected from the outside. Which of the following would resolve this concern? (Choose two.)



Answer : C, E

The best solutions to resolve the concern of transmissions from the building being detected from outside are signal blocking and reflective glass. Signal blocking is a method of preventing or interfering with electromagnetic signals from escaping or entering a certain area. Signal blocking can be achieved by using various materials or devices that create physical barriers or generate noise or jamming signals. Signal blocking can protect data transmissions from being intercepted or eavesdropped by unauthorized parties. Reflective glass is a type of glass that has a coating or film that reflects light and heat. Reflective glass can reduce glare and solar radiation, as well as prevent visual observation from outside. Reflective glass can enhance privacy and security for datacenter operations.


Question 3

An administrator is troubleshooting a failed NIC in an application server. The server uses DHCP to get all IP configurations, and the server must use a

specific IP address. The administrator replaces the NIC, but then the server begins to receive a different and incorrect IP address. Which of the following will enable the server to get the proper IP address?



Answer : A

A DHCP reservation is a way to assign a specific IP address to a device based on its MAC address, which is a unique identifier for each network interface card (NIC). When the administrator replaced the NIC, the MAC address of the server changed, and the DHCP server no longer recognized it as the same device. Therefore, the DHCP server assigned a different IP address to the server, which was incorrect for the application. To fix this problem, the administrator needs to modify the DHCP reservation to use the new MAC address of the NIC, so that the server can get the proper IP address.

A WWNN (World Wide Node Name) is a unique identifier for a Fibre Channel node, which is a device that can communicate over a Fibre Channel network. A WWNN is not related to DHCP or IP addresses, and it is not used for DHCP reservations. Therefore, options B and D are incorrect.

Updating the local hosts file with the correct IP address (option C) is also incorrect, because it does not solve the problem of getting the correct IP address from the DHCP server. The hosts file is a local file that maps hostnames to IP addresses, and it is used to override DNS queries. However, it does not affect how the DHCP server assigns IP addresses to devices. Moreover, updating the hosts file manually on every device that needs to communicate with the server is not a scalable or efficient solution.

Question 4

A server administrator is completing an OS installation for a new server. The administrator patches the server with the latest vendor-suggested software, configures DHCP, and verifies all network cables are properly connected in the IDF, but there is no network connectivity. Which of the following is the MOST likely reason for the lack of connectivity?



Answer : A

If the server administrator patches the server with the latest vendor-suggested software, configures DHCP, and verifies all network cables are properly connected in the IDF, but there is no network connectivity, then the most likely reason for the lack of connectivity is that the VLAN is improperly configured. A VLAN (Virtual Local Area Network) is a logical grouping of network devices that share the same broadcast domain and can communicate with each other without routing. If the server is assigned to a different VLAN than the DHCP server or the default gateway, itwill not be able to obtain an IP address or reach other network devices. The DNS configuration is not relevant for network connectivity, as DNS only resolves names to IP addresses. The OS version is not likely to be incompatible with the network switch vendor, as most network switches use standard protocols and interfaces. The HIDS (Host-based Intrusion Detection System) is not likely to prevent the connection, as HIDS only monitors and alerts on suspicious activities on the host.

Question 5

Which of the following technologies can successfully back up files that are used by other processes without stopping those processes?



Answer : D

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:AnOpen file backupsolution allows files that are in use by other processes to be backed up without stopping those processes. This is especially important in environments where critical applications and services must remain operational while backup operations occur. Technologies like VSS (Volume Shadow Copy Service) in Windows provide this functionality, enabling the backup of open files such as databases or system files without disrupting the processes.

DifferentialandArchivebackups are types of backup strategies but do not specifically address backing up open or in-use files.

Synthetic fullbackups refer to a method of creating a full backup by combining incremental backups and a full backup, but it does not specifically address open files.


Question 6

A server technician has been asked to upload a few files from the internal web server to the internal FTP server. The technician logs in to the web server using PuTTY, but the connection to the FTP server fails. However, the FTP connection from the technician's workstation is sucessful. To troubleshoot the issue, the technician executes the following command on both the web server and the workstation:

ping ftp.acme.local

The IP address in the command output is different on each machine. Which of the following is the MOST likely reason for the connection failure?



Answer : D

A misconfigured hosts file can cause name resolution issues on a server. A hosts file is a text file that maps hostnames to IP addresses on a local system. It can be used to override DNS settings or provide custom name resolution for testing purposes. However, if the hosts file contains incorrect or outdated entries, it can prevent the system from resolving hostnames properly and cause connectivity problems. To fix this issue, the administrator should check and edit the hosts file accordingly.


Question 7

An administrator is tasked with building an environment consisting of four servers that can each serve the same website. Which of the following concepts is described?



Answer : A

Load balancing is a technique used to distribute workloads evenly across multiple servers, ensuring no single server is overwhelmed. This is especially important in environments where high availability and reliability are critical, such as when multiple servers are serving the same website. By doing so, load balancing improves the responsiveness and availability of applications or websites.

Load balancing refers to the process of distributing network or application traffic across multiple servers to ensure no single server becomes overwhelmed, thereby improving responsiveness and availability of applications or websites. In the scenario described, where four servers are set up to each serve the same website, the concept of load balancing is applied. This setup aims to distribute incoming requests evenly among the servers to maximize speed and capacity utilization while ensuring no one server is overburdened, which can lead to improved overall performance of the website. Options B, C, and D do not accurately describe the scenario of distributing traffic for the same website across multiple servers.
