NEW QUESTION 7

A company wants to save money by leveraging the cloud while still being able to customize the infrastructure. Which of the following cloud models
would best address the company's needs?

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

Answer: C

Explanation:
A hybrid cloud model would best address the company’s needs of saving money by leveraging the cloud while still being able to customize the infrastructure. A hybrid cloud model is a combination of public and private cloud services, connected by a secure network. A public cloud service is a cloud service that is offered by a third-party provider over the Internet, and is shared by multiple customers. A private cloud service is a cloud service that is dedicated to a single customer, and is hosted either on-premises or by a third-party provider. A hybrid cloud model allows the company to use the public cloud for cost-effective and scalable services, such as storage, backup, or analytics, and use the private cloud for more sensitive or customized services, such as security, compliance, or performance. A hybrid cloud model also enables the company to move workloads between the public and private cloud as needed, depending on the demand, availability, or cost. A hybrid cloud model can provide the company with the best of both worlds: the flexibility and efficiency of the cloud, and the control and customization of the infrastructure.

NEW QUESTION 10

Which of the following cloud models maintains access, even when a local internet outage
occurs?

• A. Private
• B. SaaS
• C. Community
• D. Public

Answer: A

Explanation:
In a private cloud model, the cloud infrastructure is maintained within a company's own data center and is used exclusively by that company. Private clouds offer the advantage of maintaining access even when a local internet outage occurs, since the cloud infrastructure is not dependent on a public network connection.
Software as a Service (SaaS) is a cloud model in which software applications are hosted by a third-party provider and made available to customers over the internet. SaaS is not designed to maintain access in the event of a local internet outage.
A community cloud is a shared infrastructure that is used by multiple organizations, typically from the same industry or with similar requirements. Community clouds are not designed to maintain access in the event of a local internet outage.
A public cloud is a cloud infrastructure that is maintained by a third-party provider and is made available to the public over the internet. Public clouds are not designed to maintain access in the event of a local internet outage.

NEW QUESTION 11

A technician is configuring a workstation to be used as a VM host. After installing the necessary software, the technician is unable to create any VMs. Which of the following actions should be performed?

• A. Disable the BIOS password.
• B. Enable TPM.
• C. Enable multithreading.
• D. Enable Fast Startup.

Answer: B

Explanation:
If you want to install Windows 11 on a virtual machine using Hyper-V, you will have to use a “Generation 2” VM and enable the “trusted platform module” (TPM) and Secure Boot options. Otherwise, the OS won’t install.
Starting with Windows 11, Microsoft is changing the system requirement and making TPM 2.0 and Secure Boot a prerequisite to perform an in-place upgrade or clean install the new version on any device. This is in addition to the new 4GB of RAM and at least 64GB of storage.
quoted from here:
https://pureinfotech.com/enable-tpm-secure-boot-hyperv-install-windows-11/ Furthermore, Multithreading is not a requirement for hyper-v hosting.
To create virtual machines on a workstation, the technician needs to enable Trusted Platform Module (TPM) in the system BIOS. TPM is a hardware-based security feature that helps protect the system from unauthorized access and tampering. It is required for many virtualization technologies, including Hyper-V, VirtualBox, and VMware. References: CompTIA A+ Certification Exam Objectives - 220-1002: 2.7 Explain the basics of virtualization.

NEW QUESTION 12

To control costs a company provides a limited number or users with company phones One of these users opens a support ticket because the phone no longer allows internet Drowsing over a cellular connection The user acknowledges that the phone worked before the user's child streamed several movies using the device Which of the following describes why the phone cannot browse the Internet?

• A. The child accidentally connected to a neighbor's WLAN
• B. The company's group policy disabled the device
• C. The device has a data cap and has reached that limit
• D. The device's plan has been unpaid

Answer: C

Explanation:
It is common for companies to place a data cap on the devices they provide to their employees, to control costs. If a user has exceeded the data cap, the phone may no longer allow internet browsing over a cellular connection. This is usually because the cellular data usage has exceeded the allotted amount for the particular plan the device is on, and the service provider has temporarily suspended the data connection.
It is unlikely that the child accidentally connected to a neighbor's WLAN because this would not affect the cellular data connection. Similarly, it is unlikely that the company's group policy has disabled the device, as this would likely affect all devices under the same policy. If the device's plan has been unpaid, the service provider would likely temporarily suspend all services, not just the cellular data connection.

NEW QUESTION 14

While on a VoIP call, one user is unable to understand the other because the audio is breaking up. Which of the following BEST describes what is occurring on the call?

• A. High latency
• B. External interference
• C. No connectivity
• D. Port flapping

Answer: A

Explanation:
High latency is what best describes what is occurring on a VoIP call when one user is unable to understand the other because the audio is breaking up. Latency is the delay between sending and receiving data over a network, and high latency can cause poor quality or interruptions in VoIP calls. External interference, no connectivity, or port flapping are not likely to cause audio breaking up, but rather complete loss of signal or connection.

NEW QUESTION 15

Given the following output from a cable tester:
===================
= Open
=12345678=
=12 45 78=
===================
Which of the following tools should the technician use to resolve this issue? (Select two).

• A. Loopback plug
• B. Network tap
• C. Toner probe
• D. Crimper
• E. Punchdown tool
• F. Wi-Fi analyzer

Answer: DE

Explanation:
The output from the cable tester indicates that there is an open fault in the cable, which means that one or more of the wires in the cable are not connected properly or are broken. The open fault affects the wires 3, 4, and 6, which are used for transmitting and receiving data in Ethernet networks. The open fault can cause network connectivity issues, such as no link, slow speed, or packet loss12.
To resolve this issue, the technician should use a crimper and a punchdown tool, which are tools that are used to attach connectors to cables or wires to patch panels. A crimper is a tool that squeezes or crimps a connector, such as an RJ-45, to the end of a cable, ensuring that the wires are securely inserted into the pins of the connector. A punchdown tool is a tool that pushes or punches a wire into a slot on a patch panel, creating a connection between the wire and the panel. Both tools can be used to fix or replace the faulty wires or connectors that cause the open fault12.
The other options are not as effective or relevant as a crimper and a punchdown tool. A loopback plug is a tool that is used to test the functionality of a network port or device, by sending and receiving signals from the same port or device. A loopback plug can help diagnose network problems, such as faulty ports or devices, but it cannot fix the open fault in the cable12. A network tap is a tool that is used to monitor or capture network traffic, by creating a copy of the data that passes through a network link. A network tap can help analyze network performance, security, or troubleshooting, but it cannot fix the open fault in the cable12. A toner probe is a tool that is used to trace or identify a cable or wire, by sending and detecting an audible tone along the cable or wire. A toner probe can help locate or label network cables or wires, but it cannot fix the open fault in the cable12. A Wi- Fi analyzer is a tool that is used to scan or measure wireless networks, by displaying information such as signal strength, channel, encryption, etc. A Wi-Fi analyzer can help optimize or troubleshoot wireless networks, but it cannot fix the open fault in the cable12.

NEW QUESTION 16

A company wants to add virtual servers to handle unusually high web traffic usage. Which of the following is the most efficient way?

• A. Community cloud
• B. File synchronization
• C. Rapid elasticity
• D. Cloud VDI

Answer: C

Explanation:
Rapid elasticity is the ability of a cloud service to scale up or down the resources (such as virtual servers, storage, bandwidth, etc.) according to the demand of the users. This is an efficient way to handle unusually high web traffic usage, as it allows the company to provision more virtual servers when needed and release them when not needed, without wasting resources or paying for unused capacity. Rapid elasticity also improves the performance and availability of the web service, as it can adjust to the fluctuations in traffic and avoid overloading or downtime.
