A server is only able to connect to a gigabit switch at 100Mb. Other devices are able to access the network port at full gigabit speeds, and when the server is brought to another location, it is able to connect at full gigabit speed. Which of the following should an administrator check first?
- A. The network cable
- B. The network drivers
- C. The VLAN configuration
- D. The switch management
Answer: A
Explanation:
Explanation
The first thing that the administrator should check is the network cable. The network cable is a physical medium that connects a server to a switch or other network device. The network cable can affect the speed and quality of the network connection, depending on its type, length, and condition. If the network cable is damaged, faulty, or incompatible, it can cause the server to connect at a lower speed than expected. Therefore, the administrator should check the network cable for any signs of wear, tear, or mismatch, and replace it if necessary.

NEW QUESTION # 36
A very old PC is running a critical, proprietary application in MS-DOS. Administrators are concerned about the stability of this computer. Installation media has been lost, and the vendor is out of business. Which of the following would be the BEST course of action to preserve business continuity?
- A. Perform scheduled chkdsk tests.
- B. Purchase matching hardware and clone the disk.
- C. Upgrade the hard disk to SSD.
- D. Perform quarterly backups.
Answer: B
Explanation:
The best course of action to preserve business continuity for a very old PC that is running a critical, proprietary application in MS-DOS is to purchase matching hardware and clone the disk. This way, the technician can create an exact copy of the PC's configuration and data on another PC that has the same specifications and compatibility. This will ensure that the application can run smoothly on the new PC without any installation or configuration issues. Performing scheduled chkdsk tests would not help, as chkdsk is a tool that checks and repairs disk errors, but does not prevent hardware failures or software compatibility issues. Upgrading the hard disk to SSD would not help either, as SSDs may not be compatible with the old PC or the MS-DOS operating system. Performing quarterly backups would help with data protection, but not with hardware availability or software compatibility.

NEW QUESTION # 37
Hosting data in different regional locations but not moving it for long periods of time describes:
- A. off-site storage.
- B. data at rest.
- C. a cold site.
- D. on-site retention.
Answer: B
Explanation:
Data at rest refers to data that is stored in a persistent state on any device or media, such as hard drives, tapes, or cloud storage. Data at rest does not move for long periods of time unless it is accessed or modified by authorized users or applications. A cold site (A) is a backup location that has minimal or no equipment and resources to resume business operations in case of a disaster. On-site retention © is a policy of keeping backup data on premises for a certain period of time before transferring it to an off-site location. Off-site storage (D) is a method of storing backup data in a remote location that is physically or logically separated from the primary site.

NEW QUESTION # 39
A technician has several possible solutions to a reported server issue. Which of the following BEST represents how the technician should proceed with troubleshooting?
- A. Document the findings, actions, and outcomes throughout the process.
- B. Determine whether there is a common element in the symptoms causing multiple problems.
- C. Perform a root cause analysis.
- D. Make one change at a time and test.
Answer: D
Explanation:
This is the best way to proceed with troubleshooting when the technician has several possible solutions to a reported server issue. Making one change at a time and testing allows the technician to isolate the cause and effect of each solution and determine which one works best. It also helps to avoid introducing new problems or complicating existing ones by making multiple changes at once. Determining whether there is a common element in the symptoms causing multiple problems is a good step to perform before identifying possible solutions, but not after. Performing a root cause analysis is a good step to perform after resolving the issue, but not during. Documenting the findings, actions, and outcomes throughout the process is a good practice to follow at every step of troubleshooting, but not a specific way to proceed with testing possible solutions.

NEW QUESTION # 40
A systems administrator has been alerted to a zero-day vulnerability that is impacting a service enabled on a server OS. Which of the following would work BEST to limit an attacker from exploiting this vulnerability?
- A. Closing open ports
- B. Enabling a NIDS
- C. Enabling antivirus protection
- D. Installing the latest patches
Answer: A
Explanation:
A zero-day (or 0-day) vulnerability is a software vulnerability that is discovered by attackers before the vendor has become aware of it. By definition, no patch exists for zero day vulnerabilities and user systems have no defenses in place, making attacks highly likely to succeed. One of the most common recovery methods for a zero-day attacks is to physically (or via a network-based firewall) remove all access from anyone who would have the ability to exploit it. Blocking the ports used for Remote PowerShell can limit these attacks.
NEW QUESTION # 41
A technician is unable to access a server's package repository internally or externally. Which of the following are the MOST likely reasons? (Choose two.)
- A. The technician does not have sufficient privileges
- B. The local system log file is full
- C. The default gateway is incorrect
- D. The server has an architecture mismatch
- E. The system time is not synchronized
- F. The external firewall is blocking access
Answer: C,F
Explanation:
The most likely reasons why the technician is unable to access a server's package repository internally or externally are that the external firewall is blocking access and that the default gateway is incorrect. A package repository is a source of software packages that can be installed or updated on a server using a package manager tool. A package repository can be accessed over a network using a URL or an IP address. However, if there are any network issues or misconfigurations, the access to the package repository can be blocked or failed. An external firewall is a device or software that controls the incoming and outgoing network traffic based on predefined rules or policies. An external firewall can block access to a package repository if it does not allow traffic on certain ports or protocols that are used by the package manager tool. A default gateway is a device or address that routes network traffic from one network to another network. A default gateway can be incorrect if it does not match the actual device or address that connects the server's network to other networks, such as the internet. An incorrect default gateway can prevent the server from reaching the package repository over other networks.
NEW QUESTION # 42
An administrator discovers a misconfiguration that impacts all servers but can be easily corrected. The administrator has a list of affected servers and a script to correct the issue. Which of the following scripting principles should the administrator use to cycle through the list of servers to deliver the needed change?
- A. Constant
- B. Loop
- C. String
- D. Linked list
Answer: B
Explanation:
A loop is a programming construct that allows a block of code to be executed repeatedly until a certain condition is met1. A loop can be used to cycle through a list of servers and run a script on each one of them. For example, in Python, a loop can be written as:
Python
This code is AI-generated. Review and use carefully. Visit our FAQ for more information.
Copy
# Assume servers is a list of server names
for server in servers:
# Run the script on the server
run_script(server)
A loop can help automate the task of correcting the misconfiguration on all servers, saving time and effort.

An administrator is configuring the storage for a new database server, which will host databases that are mainly used for archival lookups. Which of the following storage types will yield the fastest database read performance?
- A. SSD
- B. 15K rpm SCSI
- C. NAS
- D. 10K rpm SATA
Answer: A
Explanation:
Explanation
The storage type that will yield the fastest database read performance is SSD. SSD (Solid State Drive) is a type of storage device that uses flash memory to store data. SSDs have no moving parts and can access data faster than traditional hard disk drives (HDDs) that use spinning platters and magnetic heads. SSDs are especially suitable for databases that are mainly used for archival lookups, as they can provide faster response times and lower latency for read operations.

NEW QUESTION # 45
A technician needs to install a Type 1 hypervisor on a server. The server has SD card slots, a SAS controller, and a SATA controller, and it is attached to a NAS. On which of the following drive types should the technician install the hypervisor?
- A. SATA drive
- B. SD card
- C. SAS drive
- D. NAS drive
Answer: C
Explanation:
Explanation
The technician should install the Type 1 hypervisor on a SAS drive. A Type 1 hypervisor is a layer of software that runs directly on top of the physical hardware and creates virtual machines that share the hardware resources. A Type 1 hypervisor requires fast and reliable storage for optimal performance and stability. A SAS drive is a type of hard disk drive that uses Serial Attached SCSI (SAS) as its interface protocol. SAS drives offer high speed, low latency, and high reliability compared to other types of drives, such as SD cards, NAS drives, or SATA drives. SD cards are flash memory cards that offer low cost and portability but have low speed, low capacity, and low durability. NAS drives are network-attached storage devices that offer high capacity and easy access but have high latency and low reliability due to network dependency. SATA drives are hard disk drives that use Serial ATA (SATA) as their interface protocol. SATA drives offer moderate speed, moderate cost, and moderate reliability but have lower performance and durability than SAS drives.

NEW QUESTION # 49
A server is performing slowly, and users are reporting issues connecting to the application on that server. Upon investigation, the server administrator notices several unauthorized services running on that server that are successfully communicating to an external site. Which of the following are MOST likely causing the issue? (Choose two.)
- A. The firewall rule for the server is misconfigured
- B. Unnecessary services are disabled on the server
- C. Intrusion detection is enabled on the network
- D. SELinux is enabled on the server
- E. The server is infected with a virus
- F. Adware is installed on the users' devices
Answer: A,E
Explanation:
Adware on the users' machine is a large assumption. If everyone is affected it's unlikely that everyone has adware, and more likely that the server has a virus slowing it down.
The server most likely got the virus from open ports i.e. misconfigured firewall.

- B. Unnecessary services are disabled on the server
- C. The firewall rule for the server is misconfigured
- D. Intrusion detection is enabled on the network
- E. The server is infected with a virus
- F. Adware is installed on the users' devices
Answer: A,E
Explanation:
The server is infected with a virus and SELinux is enabled on the server are most likely causing the issue of unauthorized services running on the server. A virus is a type of malicious software that infects a system and performs unwanted or harmful actions, such as creating, modifying, deleting, or executing files. A virus can also create backdoors or open ports on a system to allow remote access or communication with external sites. SELinux (Security-Enhanced Linux) is a security module for Linux systems that enforces mandatory access control policies on processes and files. SELinux can prevent unauthorized services from running on a server by restricting their access to resources based on their security context. However, SELinux can also cause problems if it is not configured properly or if it conflicts with other security tools.
