• Question 251:

  Which of the following models is an example of metered utilization?

  A. Reserved instance
  B. Pay-as-you-go
  C. Subscription-based
  D. Multitenant
  B. Pay-as-you-go

  ---

  Explanation

  Metered utilization is a pricing model for cloud computing services, where the customer pays only for the amount of resources that are consumed, such as CPU time, memory, storage, bandwidth, etc. The customer is billed based on the actual usage of the resources, rather than a fixed or upfront fee. Metered utilization is also known as usage- based pricing or pay-per-use12. Pay-as-you-go is an example of metered utilization, where the customer pays for the cloud resources on demand, without any long-term commitment or contract. The customer can scale up or down the resources as needed, and only pay for what is used. Pay-as-you-go is a flexible and cost-effective option for customers who have unpredictable or variable workloads, or who want to try out new services or features12. The other options are not examples of metered utilization. Reserved instance is a pricing model where the customer pays a discounted rate for a fixed amount of cloud resources for a specified period of time, such as one or three years. The customer can reserve the resources in advance, and benefit from lower costs and guaranteed availability. Reserved instance is suitable for customers who have predictable or steady workloads, or who want to optimize their budget12. Subscription-based is a pricing model where the customer pays a fixed fee for a set of cloud services or features for a certain period of time, such as monthly or annually. The customer can access the services or features as much as needed, without worrying about the usage or consumption of the resources. Subscription-based is suitable for customers who want to have a consistent and predictable cost, or who want to access premium or exclusive services or features12. Multitenant is not a pricing model, but a cloud architecture where multiple customers share the same physical or virtual resources, such as servers, databases, applications, etc. The resources are isolated and secured for each customer, and the customers can benefit from lower costs, higher scalability, and faster updates. Multitenant is a common characteristic of public cloud services, where the cloud provider manages and maintains the resources for the customers12.

• Question 254:

  A user purchased a retail router and would like to set up a private network. Which of the following network address ranges should the user configure?

  A. 170.50.0.0 to 170.50.255.255
  B. 172.16.0.0 to 172.31.255.255
  C. 224.0.0.0 to 224.255.255.255
  D. 239.0.0.0 to 239.255.255.255
  B. 172.16.0.0 to 172.31.255.255

  ---

  Explanation

  The user should configure a private network using one of the reserved IP address ranges specified for private use by RFC 1918. These ranges are:

  10.0.0.0 to 10.255.255.255

  172.16.0.0 to 172.31.255.255

  192.168.0.0 to 192.168.255.255

  Option B falls within the second range (172.16.0.0 to 172.31.255.255), which is commonly used for private networks.

• Question 255:

  A remote user called the help desk to report a notification indicating there is limited or no connectivity. The user can access local file folders and other local machines but none of the organization's servers or network items. Web pages do not appear to function either. Which of the following is the MOST likely cause of the issue?

  A. The user's internet connection is down.
  B. The user's domain account is locked out.
  C. The user's switch has stopped working.
  D. The user's IP address needs to be renewed.
  A. The user's internet connection is down.

  ---

  Explanation

  Based on the information provided in the scenario, the most likely cause of the issue is that the user's internet connection is down (option A). This would explain why the user is unable to access any of the organization's servers or network items and why web pages are not functioning. However, since the user can still access local file folders and other local machines, it suggests that their local network is still functioning. The user can access local file folders and other local machines but none of the organization's servers or network items, indicating that the issue is with the user's internet connection, not with the user's domain account, switch, or IP address. When a user receives a notification indicating that there is limited or no connectivity, it means that their device is unable to establish a connection to the network. In this scenario, the user can access local file folders and other local machines but is unable to access any of the organization's servers or network items and web pages are not functioning. This suggests that the issue is with the user's internet connection. An internet connection allows a device to communicate with other devices and servers outside of its local network. If the internet connection is down or not functioning properly, the device will be unable to access any resources outside of its local network. This would explain why the user in this scenario can still access local resources but is unable to access any of the organization's servers or network items.

• Question 256:

  An organization maintains various record types, including health and criminal justice records. Which of the following cloud environments is the organization MOST likely to use to limit the attack surface?

  A. Public
  B. Hybrid
  C. Community
  D. Private
  D. Private

  ---

  Explanation

  Private cloud environments are designed for use by a single organization and offer the greatest control over security and access to data. They are typically used for sensitive or confidential data, such as health and criminal justice records.

  Public cloud environments are shared by multiple organizations and offer less control over security and access to data. Hybrid cloud environments combine public and private clouds, while community clouds are shared by multiple

  organizations with similar needs.

• Question 257:

  A user has noticed high CPU temperatures when gaming. The user would like to lower the CPU temperature, and cost is not an issue. Which of the following should the user do to BEST cool the CPU while keeping noise to a minimum?

  A. Upgrade the thermal paste.
  B. Use a copper heat sink.
  C. Upgrade the CPU fan.
  D. Install liquid cooling.
  D. Install liquid cooling.

  ---

  Explanation

  Liquid cooling is a method of cooling the CPU by circulating a liquid through a closed loop that absorbs heat from the CPU and transfers it to a radiator. Liquid cooling is more effective and quieter than air cooling, which uses a fan and a heat sink. However, liquid cooling is also more expensive and complex to install. Upgrading the thermal paste, using a copper heat sink, or upgrading the CPU fan are ways to improve air cooling, but they will not lower the CPU temperature as much as liquid cooling.

• Question 258:

  A technician is creating a consecutive range of IP addresses that a server can select from to fulfill requests from network clients. Which of the following is the technician creating?

  A. DHCP scope
  B. Static IP list
  C. DNS A records
  D. Automatic private IP addressing
  A. DHCP scope

  ---

  Explanation

  The correct answer is A. DHCP scope. A DHCP scope is a consecutive range of IP addresses that a DHCP server can select from to fulfill requests from network clients. A DHCP server is a device that automatically assigns IP addresses and other network configuration parameters to devices that request them. A DHCP scope defines the pool of available IP addresses, as well as the subnet mask, default gateway, DNS servers, and lease duration for each IP address. A DHCP scope can also include exclusions, reservations, and policies to customize the IP address allocation process12. A static IP list is a list of IP addresses that are manually assigned to devices and do not change over time. A static IP list does not require a DHCP server, but it requires more administrative effort and coordination to avoid conflicts or errors. A static IP list is not a consecutive range of IP addresses that a server can select from3. DNS A records are DNS records that map a domain name to an IPv4 address. DNS is a system that translates human-readable domain names into machine-readable IP addresses. DNS A records are not a range of IP addresses that a server can select from, but a way of resolving domain names to IP addresses. Automatic private IP addressing (APIPA) is a feature of Windows that allows devices to self-assign an IP address in the absence of a DHCP server or a static IP configuration. APIPA uses the 169.254.0.0/16 address range, which is reserved for link-local communication. APIPA does not create a range of IP addresses that a server can select from, but a fallback mechanism for devices that cannot obtain an IP address from another source.
