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.

A port scanner is the tool that would most likely help the analyst determine if the applications are

running on a remote server. A port scanner is a software tool that scans a network device for open

ports. Ports are logical endpoints for network communication that are associated with specific

applications or services. By scanning the ports on a remote server, the analyst can identify what

applications or services are running on that server and what protocols they are using. A port scanner

can also help detect potential vulnerabilities or misconfigurations on a server.

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.

The subnet mask is most likely containing an error that prevents the application server from

communicating with the newly installed database server. The subnet mask is a binary number that

defines how many bits of an IP address are used for the network portion and how many bits are used

for the host portion. The subnet mask determines which devices belong to the same network or

subnet and can communicate directly with each other without routing or switching devices. The

subnet mask of the database server is 255.255.O.O, which means that all 32 bits of its IP address are

used for the network portion and none for the host portion, which is invalid and makes it

unreachable by any other device on any network or subnet. The subnet mask of the application

server is 255.O.O.O, which means that only 8 bits of its IP address are used for the network portion

and 24 bits are used for the host portion, which is also uncommon and makes it incompatible with

most networks or subnets. Reference: [CompTIA Server+ Certification Exam Objectives], Domain 4.0:

Networking, Objective 4.1: Given a scenario, configure network settings for servers.

If users cannot access a new server by name, but the server does respond to a ping request using its

IP address, it means that there is a problem withname resolution. The DNS (Domain Name System) is

a service that maps hostnames to IP addresses and vice versa. Therefore, the best step to perform

next is to examine the DNS to see if the new server record exists and matches its IP address. If not,

the DNS record needs to be added or updated accordingly. Running the tracert command from a

workstation would not help with name resolution, as it only shows the route taken by packets to

reach a destination by IP address. Correcting the missing DHCP scope would not help either, as DHCP

(Dynamic Host Configuration Protocol) only assigns IP addresses and other network settings to

clients, but does not resolve names. Updating the workstation hosts file would be a temporary

workaround, but not a permanent solution, as it would require manually editing every workstation’s

hosts file with the new server’s name and IP address. Reference:

QSFP+ is a type of connector that should be used to connect a server to a switch that uses 40G

network connectivity. QSFP+ (Quad Small Form-factor Pluggable Plus) is a compact, hot-pluggable

transceiver module that supports data rates up to 40 Gbps. QSFP+ modules can be used for various

network protocols and media types, such as Ethernet, Fibre Channel, InfiniBand, or optical fiber.

QSFP+ modules have a 38-pin edge connector and can be inserted into a QSFP+ port on a switch or a

server. SFP+ (Small Form-factor Pluggable Plus) is a type of connector that supports data rates up to

10 Gbps, but not 40 Gbps. SFP+ modules have a 20-pin edge connector and can be inserted into an

SFP+ port on a switch or a server. GBIC (Gigabit Interface Converter) is an older type of connector

that supports data rates up to 1 Gbps, but not 40 Gbps. GBIC modules have an SC duplex connector

and can be inserted into a GBIC port on a switch or a server. SFP (Small Form-factor Pluggable) is

another older type of connector that supports data rates up to 1 Gbps or 4 Gbps, but not 40 Gbps.

SFP modules have an LC duplex connector and can be inserted into an SFP port on a switch or a

server. Reference: https://www.howtogeek.com/190014/virtualization-basics-understandingtechniques-and-fundamentals/ https://www.howtogeek.com/428483/what-is-end-to-end-

The steps in the troubleshooting theory that should be performed after a solution has been

implemented are document the findings and notify the users. The troubleshooting theory is a

systematic process of identifying and resolving problems or issues with a system or device. The

troubleshooting theory consists of several steps that can be summarized as follows:

Identify the problem: Gather information, scope the issue, establish a theory of probable cause.

Establish a plan of action: Test the theory, determine next steps, escalate if necessary.

Implement the solution: Execute the plan, verify functionality, prevent recurrence.

Document the findings: Record actions taken, outcomes achieved, lessons learned.

Notify the users: Communicate resolution status, confirm satisfaction, provide follow-up.

Documenting the findings is an important step that helps create a record of what was done and why,

what worked and what didn’t, and what can be improved or avoided in the future. Documenting the

findings can also help with reporting, auditing, compliance, or training purposes. Notifying the users

is another important step that helps inform the affected parties of what was done and how it was

resolved, confirm that the problem is fixed and that they are satisfied with the outcome, and provide

any follow-up instructions or recommendations.
