NO.130 A systems administrator recently installed a new virtual server. After completing the installation, the administrator was only able to reach a few of the servers on the network. While testing, the administrator discovered only servers that had similar IP addresses were reachable. Which of the following is the most likely cause of the issue?

The jumbo frames are not enabled.

The subnet mask is incorrect.

There is an IP address conflict.

There is an improper DNS configuration.

Explanation
A subnet mask is a number that distinguishes the network address and the host address within an IP address1.
A subnet mask allows network traffic to understand IP addresses by splitting them into the network and host addresses. If the subnet mask is incorrect, the network traffic may not be able to determine the correct destination for the packets, and only reach some of the servers that have similar IP addresses. For example, if the new virtual server has an IP address of 192.168.1.100 and a subnet mask of 255.255.0.0, it can only communicate with servers that have IP addresses in the range of 192.168.0.0 to 192.168.255.2552. To fix this issue, the systems administrator needs to check and correct the subnet mask of the new virtual server according to the network configuration.

NO.131 Users report that the FinanceApp software is not running, and they need immediate access. Issues with the FinanceApp software occur every week after the IT team completes server system updates. The users, however, do not want to contact the help desk every time the issue occurs. The users also report the new MarketApp software is not usable when it crashes, which can cause significant downtime. The technician who restarted the MarketApp software noticed it is running under a test account, which is a likely cause of the crashes.
INSTRUCTIONS
Using the Services menu provided, modify the appropriate application services to remedy the stated issues.

See the solution in explanation.
Explanation
FinanceApp software is running as a service named “FinanceApp Service”. The service description says
“Provides financial data and calculations for the FinanceApp software”. The service status is “Stopped”, which means that the service is not running and the software is not functional. The service startup type is “Manual”, which means that the service needs to be started manually by the user or the administrator. The service log on as is “Local System”, which means that the service runs under a predefined local account that has extensive privileges on the local computer.
To fix the issue with the FinanceApp software, you need to do two things:
First, you need to start the service, so that the software can run. To do this, you can right-click on the service name and select “Start” from the menu. Alternatively, you can select the service name and click on the “Start” button on the toolbar. You should see a message saying that the service has started successfully.
Second, you need to change the service startup type, so that the service can start automatically every time the server boots up. This way, you don’t have to contact the help desk every time the issue occurs.
To do this, you can right-click on the service name and select “Properties” from the menu. Alternatively, you can select the service name and click on the “Properties” button on the toolbar. You should see a window with several tabs and options. On the “General” tab, under “Startup type”, you can select
“Automatic” from the drop-down list. Then, click on “OK” to save your changes.
By doing these two steps, you should be able to use the FinanceApp software without any problems.
The MarketApp software is running as a service named “MarketApp Service”. The service description says
“Provides market data and analysis for the MarketApp software”. The service status is “Running”, which means that the service is running and the software is functional. However, as you reported, the software may crash sometimes, which can cause significant downtime. The service startup type is “Automatic”, which means that the service starts automatically every time the server boots up. The service log on as is
“TestAccount”, which is a test account that was probably used for development or testing purposes.
To fix the issue with the MarketApp software, you need to do one thing:
You need to change the service log on as, so that the service runs under a proper account that has sufficient permissions and security settings for production use. To do this, you can right-click on the service name and select “Properties” from the menu. Alternatively, you can select the service name and click on the “Properties” button on the toolbar. You should see a window with several tabs and options.
On the “Log On” tab, under “Log on as”, you can select either “Local System account” or “This account”. If you choose “Local System account”, then the service will run under a predefined local account that has extensive privileges on the local computer. If you choose “This account”, then you will need to enter a valid username and password for an account that has appropriate permissions and security settings for running the service. You may need to consult with your IT team or your software vendor to determine which option is best for your situation. Then, click on “OK” to save your changes.

NO.132 Which of the following testing exercises for disaster recovery is primarily used to discuss incident response strategies for critical systems without affecting production data?

Tabletcp

Backup recovery test

Lrverail over

Hot-site visit audit

NO.133 A technician set up a new multifunction printer. After adding the printer to the print server, the technician configured the printer on each user’s machine. Several days later, users reported that they were no longer able to print, but scanning to email worked. Which of the following is most likely causing this issue?

The gateway is no longer being reached.

The network firewall was enabled.

The printer’s network interface failed.

The printer had DHCP enabled.

Explanation
The most likely cause of this issue is that the printer had DHCP enabled, which changed its IP address after adding it to the print server and configuring it on each user’s machine. DHCP (Dynamic Host Configuration Protocol) is a network protocol that assigns IP addresses and other network configuration parameters to devices automatically, without manual intervention. DHCP can simplify network management and avoid IP conflicts, but it can also cause problems if the devices are not configured to use static or reserved IP addresses.
If the printer had DHCP enabled, it might have received a different IP address from the DHCP server after rebooting or reconnecting to the network, which would make it unreachable by the print server and the users’ machines that were configured with the previous IP address. Scanning to email would still work, as it does not depend on the print server or the users’ machines, but on the printer’s SMTP settings and internet connection.

NO.134 A company recently implemented VolP across a multicampus environment with ten locations. The company uses many network technologies, including fiber, copper, and wireless. Users calling between three of the locations have reported that voices sound strange.
Which of the following should be monitored to
narrow down the issue?

Disk IOPS

CPU utilization

RAM utilization

Network latency

Network latency is the measure of delay in data transmission over a network. It can affect the quality of voice over IP (VoIP) calls by causing echo, jitter, or distortion. Network latency can be caused by various factors such as network congestion, distance, routing, or bandwidth. To monitor network latency, you can use tools such as ping, traceroute, or network analyzers.
References: CompTIA Server+ Study Guide, Chapter 6: Networking, page 237.

NO.135 A server administrator has received calls regarding latency and performance issues with a file server. After reviewing all logs and server features the administrator discovers the server came with four Ethernet ports, out only one port is currently in use. Which of the following features will enable the use of all available ports using a single IP address?

Network address translation

in-band management

Round robin

NIC teaming

Explanation
NIC teaming is a feature that allows the use of multiple network interface cards (NICs) as a single logical interface with a single IP address. It can improve the network performance, bandwidth, and redundancy of a server. Verified References: [NIC teaming], [Network interface card]

NO.136 Which of the following physical security concepts would most likely be used to limit personnel access to a restricted area within a data center?

An access control vestibule

Video surveillance

Bollards

Data center camouflage

An access control vestibule is a physical security concept that limits personnel access to a restricted area within a data center. It is a small room or hallway that has two doors: one that leads to the outside and one that leads to the restricted area. The doors are controlled by an electronic lock that requires authentication, such as a card reader, biometric scanner, or keypad. Only authorized personnel can enter the vestibule and access the restricted area. References: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.1: Given a scenario, apply physical security methods to a server.

NO.137 A new 40GB NIC has just been installed in a server but is not detected within the Windows server OS. Which of the following would most likely fix the issue?

Update the firmware on the NIC.

Update the server OS.

Update the remote management console.

Update the switch firmware.

Updating the firmware on the NIC is the most likely solution to fix the issue of a new 40GB NIC not being detected within the Windows server OS. Firmware is a software program that controls the functionality of a hardware device, such as a NIC (network interface card). A NIC is a device that enables network communication for a server by providing an interface between the server and the network cable or wireless connection. Updating the firmware on the NIC can improve its performance, compatibility, and stability with the server OS and network protocols. Reference: CompTIA Server+ Certification Exam Objectives, Domain 4.0: Networking, Objective 4.1: Given a scenario, configure network settings for servers.

NO.138 A company is running an application on a file server. A security scan reports the application has a known vulnerability. Which of the following would be the company’s BEST course of action?

Upgrade the application package

Tighten the rules on the firewall

Install antivirus software

Patch the server OS

The best course of action for the company is to upgrade the application package to fix the known vulnerability.
A vulnerability is a weakness or flaw in an application that can be exploited by an attacker to compromise the security or functionality of the system. Upgrading the application package means installing a newer version of the application that has patched or resolved the vulnerability. This way, the company can prevent potential attacks that may exploit the vulnerability and cause damage or loss.

NO.139 An administrator is troubleshooting connectivity to a remote server. The goal is to remotely connect to the server to make configuration changes. To further troubleshoot, a port scan revealed the ports on the server as follows:
Port 22: Closed
Port 23: Open
Port 990: Closed
Which of the following next steps should the administrator take?
Reboot the workstation and then the server.

Open port 990 and close port 23.

Open port 22 and close port 23.

Open all of the ports listed.

Close all of the ports listed.

Port 22 is used for SSH (Secure Shell), which is a secure and encrypted protocol for remote access to a server. Port 23 is used for Telnet, which is an insecure and unencrypted protocol for remote access. Port 990 is used for FTPS (File Transfer Protocol Secure), which is a secure and encrypted protocol for file transfer. The administrator should open port 22 and close port 23 to enable SSH and disable Telnet, as SSH is more secure and reliable than Telnet. The administrator does not need to open port 990, as FTPS is not required for making configuration changes123.

NO.140 While running a local network security scan an administrator discovers communication between clients and one of the web servers is happening in cleartext. Company policy requires all communication lo be encrypted. Which of the following ports should be closed to stop the deartext communication?

443

3389

Port 21 is used for FTP (File Transfer Protocol), which is a protocol that transfers files between servers and clients in cleartext, meaning that anyone can intercept and read the data. To stop this communication, port 21 should be closed on the web server and replaced with a secure protocol, such as SFTP (Secure File Transfer Protocol) or FTPS (File Transfer Protocol Secure), which use encryption to protect the data. Verified References: [FTP vs SFTP vs FTPS]

NO.141 A server administrator is trying to determine the cause of a slowdown on a database server. Upon investigation, the administrator determines the issue is in the storage subsystem. Which of the following will most likely resolve this issue?

Increasing IOPS by implementing flash storage

Implementing deduplication on the storage

Extending capacity by installing a 4TB SATA disk

Reformatting the disk as FAT32

Explanation
Increasing IOPS (input/output operations per second) by implementing flash storage is the most likely solution to resolve a slowdown issue in the storage subsystem of a database server. Flash storage uses solid-state drives (SSDs) that have faster read/write speeds and lower latency than traditional hard disk drives (HDDs). This can improve the performance of database queries and transactions. Implementing deduplication, extending capacity, or reformatting the disk as FAT32 are not likely to resolve the issue, as they do not affect the IOPS of the storage subsystem. References: [CompTIA Server+ Certification Exam Objectives], Domain 3.0:
Storage, Objective 3.5: Summarize hardware and features of various storage technologies.

NO.142 A technician is tasked with upgrading 24 hosts simultaneously with a Type 1 hypervisor. Which of the following protocols should the technician use for this upgrade?

VPN

TFTP

SSH

HTTP

TFTP (Trivial File Transfer Protocol) is a simple and lightweight protocol that can be used to transfer files over a network. TFTP is often used to upgrade firmware or software on network devices, such as routers, switches, or servers. TFTP can also be used to install a Type 1 hypervisor, such as VMware ESXi, on multiple hosts simultaneously12.

NO.143 An organization stores backup tapes of its servers at cold sites. The organization wants to ensure the tapes are properly maintained and usable during a DR scenario. Which of the following actions should the organization perform?

Have the facility inspect and inventory the tapes on a regular basis.

Have duplicate equipment available at the cold site.

Retrieve the tapes from the cold site and test them.

Use the test equipment at the cold site to read the tapes.

Explanation
The organization should retrieve the tapes from the cold site and test them to ensure they are properly maintained and usable during a DR scenario. A cold site is a location that has space and power for backup equipment, but no actual equipment installed or configured. The organization stores backup tapes of its servers at cold sites as a precaution in case of a disaster that affects its primary site. However, backup tapes can degrade over time due to environmental factors such as temperature, humidity, dust, or magnetic fields.
Therefore, the organization should periodically retrieve the tapes from the cold site and test them on compatible equipment to verify their integrity and readability.

NO.144 Which of the following techniques can be configured on a server for network redundancy?

Clustering

Vitalizing

Cloning

Teaming

Explanation
Teaming is a technique that can be configured on a server for network redundancy. Teaming involves combining two or more network adapters into a single logical unit that acts as one network interface. This way, if one network adapter fails, another one can take over without disrupting network connectivity. Teaming can also improve network performance by load balancing traffic across multiple network adapters. Clustering is a technique that involves grouping two or more servers together to act as one system for high availability and fault tolerance. Virtualizing is a technique that involves creating multiple virtual machines on a single physical server to optimize resource utilization and flexibility. Cloning is a technique that involves creating an exact copy of a server’s configuration and data for backup or migration purposes. References:

NO.145 Which of the following licensing models allows the greatest number of concurrent Windows VMS to run on a host for the lowest cost?

per user

per core

Per instance

Per concurrent user

The answer to this question may depend on several factors, such as the number and type of Windows VMs, the number and type of host machines, the number and type of users, and the specific licensing terms and conditions of each licensing model. However, based on the information available from the web search results, one possible answer is per user.
Per user licensing model is a licensing model that allows a user to access Windows VMs from any device, regardless of the number of devices or VMs. Per user licensing model is available for Windows 10 Enterprise E3/E5, Windows VDA E3/E5, and Microsoft 365 F3/E3/E5. Per user licensing model may offer the greatest number of concurrent Windows VMs to run on a host for the lowest cost if the following conditions are met:
The user needs to access multiple Windows VMs from different devices, such as desktops, laptops, tablets, or smartphones.
The user needs to access Windows VMs that run different versions or editions of Windows, such as Windows 10 Enterprise, Windows 10 Pro, or Windows 7 Enterprise.
The user needs to access Windows VMs that run on different types of host machines, such as physical servers, virtual servers, or cloud servers.
The user does not need to access Windows VMs that run on dedicated hardware or have specific performance or security requirements.
According to the web search results 1, per user licensing model costs $84 per user per year for Windows 10 Enterprise E3, $168 per user per year for Windows 10 Enterprise E5, $100.80 per user per year for Windows VDA E3, and $196.80 per user per year for Windows VDA E5. These prices are based on the Open License Program and may vary depending on the volume and agreement level2 Per core licensing model is a licensing model that requires a license for each core of the processor on the host machine that runs Windows VMs. Per core licensing model is available for Windows Server 2022 Datacenter and Standard editions. Per core licensing model may offer a lower cost than per user licensing model if the following conditions are met:
The host machine has a low number of cores or a high core density.
The host machine runs a high number of Windows VMs with low resource consumption.
The host machine runs only Windows Server VMs with the same edition as the host machine.
According to the web search results 2, per core licensing model costs $6,155 for 16 core licenses for Windows Server 2022 Datacenter edition and $1,069 for 16 core licenses for Windows Server 2022 Standard edition. These prices are suggested retail prices and may vary depending on the reseller2 Per instance licensing model is a licensing model that requires a license for each instance of Windows that runs on a host machine or a VM. Per instance licensing model is available for Windows Server 2022 Essentials edition and some older versions of Windows Server. Per instance licensing model may offer a lower cost than per user or per core licensing model if the following conditions are met:
The host machine runs only one instance of Windows Server with low resource consumption.
The host machine does not need to run any other VMs or applications.
The host machine does not need any advanced features or functions that are available in Datacenter or Standard editions.
According to the web search results 2, per instance licensing model costs $501 for one server license for Windows Server 2022 Essentials edition. This price is suggested retail price and may vary depending on the reseller2 Per concurrent user licensing model is a licensing model that allows a certain number of users to access Windows VMs at the same time, regardless of the number of devices or VMs. Per concurrent user licensing model is not available for any current version of Windows or Windows Server. Per concurrent user licensing model was available for some older versions of Windows Server Terminal Services or Remote Desktop Services, but it was discontinued due to complexity and compliance issues. Therefore, per concurrent user licensing model cannot be used for running Windows VMs on a host.
