• Question 505:

  Which of the following technologies can be used to harden guest virtual machines?

  A. Containerization

  B. Network isolation

  C. Resource reservation

  D. vTPM

  Correct Answer: D

  Explanation: A virtual Trusted Platform Module (vTPM) is a technology that can be used to harden guest virtual machines by providing them with a secure cryptographic device. A vTPM can store encryption keys, certificates, and passwords, and can perform integrity checks on the guest operating system and applications. A vTPM can also enable features such as BitLocker and Credential Guard in Windows 10 virtual machines. A. Containerization is a technology that can be used to isolate applications from the underlying operating system and hardware resources. Containerization does not directly harden guest virtual machines, but rather provides a lightweight alternative to virtualization. B. Network isolation is a technology that can be used to separate network traffic between different virtual machines or groups of virtual machines. Network isolation can help prevent unauthorized access or attacks on guest virtual machines, but it does not harden them internally.

  C. Resource reservation is a technology that can be used to guarantee a minimum amount of CPU, memory, disk, or network resources for a virtual machine or a group of virtual machines. Resource reservation can help improve the

  performance and availability of guest virtual machines, but it does not harden them against security threats. D. vTPM is a technology that can be used to harden guest virtual machines by providing them with a secure cryptographic device. A

  vTPM can store encryption keys, certificates, and passwords, and can perform integrity checks on the guest operating system and applications.

• Question 506:

  A user reports a workstation is having the following issues:

  OS performance is slow The workstation turns off randomly from time to time The fans are running loudly

  Which of the following is most likely the cause?

  A. The system is infected with malware.

  B. The CPU is overheating.

  C. The hard drive is failing.

  D. The power supply is insufficient.

  Correct Answer: B

  Explanation: One of the possible causes of slow OS performance, random shutdowns, and loud fan noise is the CPU overheating. This can happen due to dust accumulation, faulty cooling system, or high CPU usage. Overheating can

  damage the CPU and other components, so it is important to monitor the CPU temperature and take preventive measures.

• Question 507:

  A technician is mitigating threats to web clusters. Which of the following tools is the most appropriate for a technician to use to mitigate unwanted traffic against the web clusters' public-facing interface?

  A. Device encryption

  B. Intrusion detection system

  C. Antivirus/anti-malware

  D. Physical firewall

  Correct Answer: D

  A physical firewall is a hardware device that filters and blocks unwanted or malicious traffic from entering or leaving a network. A physical firewall can be configured with rules and policies to allow or deny traffic based on various criteria, such as source and destination IP addresses, ports, protocols, applications, etc. A physical firewall can also provide logging and monitoring capabilities to detect and prevent network attacks12. A physical firewall is the most appropriate tool for a technician to use to mitigate threats to web clusters, which are groups of web servers that work together to provide high availability and scalability for web applications. Web clusters are often exposed to the internet and face various types of threats, such as denial-of-service (DoS) attacks, brute force attacks, SQL injection attacks, cross-site scripting (XSS) attacks, etc. A physical firewall can protect the web clusters' public-facing interface by filtering and blocking the unwanted or malicious traffic before it reaches the web servers, thus reducing the risk of compromise or downtime34. The other options are not as effective or relevant as a physical firewall for mitigating threats to web clusters. Device encryption is a process of transforming data into an unreadable form using a secret key, which can prevent unauthorized access to the data if the device is lost or stolen. However, device encryption does not prevent network attacks or filter traffic, and it may not apply to web clusters that use shared storage or cloud services. Intrusion detection system (IDS) is a software or hardware tool that monitors network traffic and alerts the administrator of any suspicious or malicious activity. However, IDS does not block or filter traffic, and it may not be able to prevent or stop an attack in progress. IDS is often used in conjunction with a firewall, not as a replacement. Antivirus/anti-malware is a software tool that scans and removes viruses, worms, trojans, spyware, ransomware, and other malicious software from a device. However, antivirus/antimalware does not filter or block network traffic, and it may not be able to detect or prevent some web-based attacks, such as XSS or SQL injection. Antivirus/anti-malware is also often used in conjunction with a firewall, not as a replacement.

• Question 508:

  Which of the following explains how using a cloud infrastructure can provide rapid elasticity?

  A. Shared resources can reduce overhead.

  B. Customers can limit the use of a resource

  C. High availability of services can be provided

  D. Systems can be provisioned according to demand.

  Correct Answer: D

  Systems can be provisioned according to demand. This is the essence of rapid elasticity, which is one of the essential characteristics of cloud computing. Rapid elasticity means that cloud services can be scaled up or down quickly and automatically, depending on the changing needs of the customers. This provides flexibility, efficiency, and cost- effectiveness for both the customers and the providers. According to the CompTIA Core1 objectives, one of the benefits of cloud computing is rapid elasticity. A research paper on cloud elasticity also defines it as the ability to dynamically adjust the amount of resources allocated to a service in response to its workload variation.

• Question 509:

  After a company upgraded its network infrastructure, a user's desktop has been experiencing slow network speeds. Which of the following should a technician do first to improve desktops connectivity performance?

  A. Update the NIC drivers

  B. update the BIOS firmware.

  C. Replace the motherboard

  D. Replace the patch cable

  Correct Answer: D

  Explanation: The technician should replace the patch cable that connects the desktop to the network switch or outlet. The patch cable may be damaged or incompatible with the upgraded network infrastructure, which can cause slow network speeds. According to the CompTIA Core1 objectives, one of the common symptoms of a bad cable is slow transfer speeds. A research paper on network performance also states that cable quality and length can affect network speed.

• Question 510:

  Which of the following allows several websites from different companies to be housed on the same virtual server?

  A. Rapid elasticity

  B. High availability

  C. Shared resources

  D. Metered utilization

  Correct Answer: C

  Explanation: Shared resources is the concept that allows several websites from different companies to be housed on the same virtual server. A virtual server is a software-based server that runs on a physical server and can host multiple virtual machines (VMs). Each VM can run a different operating system and application, such as a website, and have its own allocated resources, such as CPU, memory, disk space, and network bandwidth. However, the VMs share the underlying hardware resources of the physical server, which reduces the cost and complexity of maintaining separate servers for each website. This also enables rapid scalability, as new VMs can be created or deleted as needed. One of the methods to host multiple websites on the same virtual server is to use virtual hosts. Virtual hosts are a feature of web servers, such as Apache, that allow the web server to serve different websites based on the domain name or IP address requested by the client. For example, a web server can host two websites, a.example.com and b.example.com, on the same virtual server and the same port (such as 80 or 443), by using virtual hosts to map each domain name to a different document root directory. The web server will then deliver the content of the corresponding website to the client based on the domain name in the HTTP request header.
