difference between cat6 and cat6a

 Cat6A speed is at least 500 MHz. This allows 10 Gbp/s (Gigabits per second) up to 328 feet (100 meters). Cat6 max speed is 250 MHz. Therefore, it only supports 10 Gbp/s to 165 feet (55 meters) under ideal conditions—less in heavy cross talk environments.

一般人群均可食用香菜。香菜可促进精子活力,提高生育能力;香菜和羊肉或狗肉同服可激发性欲,提高性能力。


香菜有损人精神、对眼不利的缺点,故不可多食、久食。


香菜辛香升散,能促进胃肠蠕动,具有开胃醒脾的作用。 身体壮实、体质较好、偶尔感冒的人却可以用它来治疗感冒。 香菜性温,脾胃虚寒的人适度吃点香菜也可起到温胃散寒、助消化、缓解胃痛的作用

azure backup vault disk size limit?

 32 TB

Individual disk size can be up to 32 TB and a maximum of 256 TB combined for all disks in a VM

Azure update domains ?

 Update domains indicate groups of VMs and underlying physical hardware that can be rebooted at the same time 1. During planned maintenance, only one update domain is rebooted at a time 1.

In Azure, an update domain is a logical group of virtual machines (VMs) that are automatically assigned by the underlying Azure platform 1. Each availability set can be configured with up to 3 fault domains and 20 update domains

- answered by Copilot


Can you do a file level restore Azure disk encryption?

 ADE encrypted VMs can't be recovered at the file/folder level. You need to recover the entire VM to restore files and folders. When restoring a VM, you can't use the replace existing VM option for ADE encrypted VMs. This option is only supported for unencrypted managed disks.

difference between copilot and copilot pro: answer by https://copilot.microsoft.com/

 https://copilot.microsoft.com/

The **main difference** between **Microsoft Copilot** and **Microsoft Copilot Pro** is that the latter is a **premium version** of the former, available at a subscription cost of **$20 per month per user** ¹²⁴.

Some of the additional features of Copilot Pro include **deeper integration with Microsoft 365**, access to **more advanced GPT models**, and the ability to create **custom Copilot GPTs** for specific uses ⁴. Copilot Pro also provides **priority access to the latest GPT models** ⁴. On the other hand, Microsoft Copilot is a **free AI tool** that allows you to use OpenAI's premium GPT-4 model for free ⁴. While Copilot Pro offers more features and faster updates, the free version of Copilot still remains a valuable tool for those who want GPT-4 access without paying ⁴.

 Use Availability Set for predictable workloads. Use Scale Set for unpredictable workloads (autoscale)

Azure Availability zones

  An Availability Zone is a physically separate zone, within an Azure region. There are three Availability Zones per supported Azure region.


Each Availability Zone has a distinct power source, network, and cooling. By designing your solutions to use replicated VMs in zones, you can protect your apps and data from the loss of a data center. If one zone is compromised, then replicated apps and data are instantly available in another zone.

Network security groups: Azure NSG rules priority

 

PriorityA number between 100 and 4096. Rules are processed in priority order, with lower numbers processed before higher numbers, because lower numbers have higher priority. Once traffic matches a rule, processing stops. As a result, any rules that exist with lower priorities (higher numbers) that have the same attributes as rules with higher priorities aren't processed.
Azure default security rules are given the highest number with the lowest priority to ensure that custom rules are always processed first.

Reliability Monitor

 Windows Server installs Reliability Monitor by default. It monitors hardware and software issues that occur during the selected time interval. Based on the number and type of issues, it assigns a number called a stability index that indicates the server's reliability. This index ranges from 1 to 10, where 1 represents the least-stable server state and 10 represents the most stable state. 

Load Reliability Monitor by accessing Control Panel, browsing to Security and Maintenance, and then selecting Maintenance.

aZURE: Virtual network service endpoints

 Use virtual network service endpoints to extend your private address space in Azure by providing a direct connection to your Azure services. Service endpoints let you secure your Azure resources to only your virtual network. Service traffic will remain on the Azure backbone, and doesn't go out to the internet.

By default, Azure services are all designed for direct internet access. All Azure resources have public IP addresses, including PaaS services such as Azure SQL Database and Azure Storage.
