4 ways of accessing Azure Resource Manager - ANSWER - Azure portal
- PowerShell
- Azure CLI (az)
- REST clients
ARM - ANSWER Azure Resource Manager
Can a Resource Group be renamed? - ANSWER No
Can a Resource Group contain resources from many different regions? - ANSWER
Yes
Can I move a resource to a different Resource Group? - ANSWER Yes
Declarative syntax - ANSWER Syntax that lets you state "Here is what I intend to
create" without having to write the sequence of programming commands to create it.
The Resource Manager template is an example of declarative syntax. In the file, you
define the properties for the infrastructure to deploy to Azure.
Delete lock - ANSWER Prevents Resource Group deletion, however an
administrator can remove the lock then delete it
Does a Resource Group reside in a particular location? - ANSWER Yes, although
the resources it contains can have different locations.
Is a lifecycle container - ANSWER Resource Group
Lock types - ANSWER Read-only or Delete
Ports used for PowerShell remoting - ANSWER TCP ports 5985 and 5986
QuickStart Templates - ANSWER Resource Manager templates provided by the
Azure community.
Resource - ANSWER A manageable item that is available through Azure. Some
common resources are a virtual machine, storage account, web app, database, and
virtual network, but there are many more.
Resource Group - ANSWER - A container that holds related resources for an Azure
solution.; The resource group can include all the resources for the solution, or only
those resources that you want to manage as a group.; You decide how you want to
allocate resources to resource groups based on what makes the most sense for your
organization.; All resources in a Resource Group should share the same lifecycle.
,Resource Manager locks - ANSWER - Prevent accidental deletion.; You can
associate the lock with a subscription, resource group, or resource. Locks are
inherited by child resources.
Resource Manager Template (a.k.a. ARM Template) - ANSWER A JavaScript
Object Notation (JSON) file that defines one or more Resources to deploy to a
Resource Group. It also defines the dependencies between the deployed resources.
The template can be used to deploy the resources consistently and repeatedly.
Deployment is expressed using declarative, rather than procedural, semantics.
Resource Manager Template Benefits - ANSWER - Improve consistency; Can
express complex deployments; Reduce manual, error-prone tasks; Templates are
code => Infrastructure as code; Promote reuse; Linkable: can be linked together, and
thus can be modular; Simplify orchestration: deploy all resources in a single
operation
Resource Provider - ANSWER A service that supplies the resources you can deploy
and manage through Resource Manager. Each resource provider offers operations
for working with the resources that are deployed. Some common resource providers
are Microsoft.Compute, which supplies the virtual machine resource,
Microsoft.Storage, which supplies the storage account resource, and Microsoft.Web,
which supplies resources related to web apps.
Resource provider examples - ANSWER - Microsoft.Compute; Microsoft.KeyVault;
Microsoft.Storage; Microsoft.Web
Template Parameters File - ANSWER ARM/JSON file that is separate from the main
file. In this file you store the literal parameter values.
Availability Set - ANSWER VMs are spread across racks. A logical feature used to
ensure that a group of related VMs are deployed so that they aren't all subject to a
single point of failure and not all upgraded at the same time during a host operating
system upgrade in the datacenter. VMs placed in a(n) ____________________
should perform an identical set of functionalities and have the same software
installed.
Availability Zone - ANSWER Unique physical locations within a region. Includes data
centers with independent power, cooling.
Can I change the size of a Virtual Machine? - ANSWER Yes, as long as your current
hardware configuration is allowed in the new size. VM may need to be rebooted.
Compute Optimized VM type - ANSWER F family. Designed to have a high CPU-to-
memory ratio. Suitable for medium traffic web servers, network appliances, batch
processes, and application servers.
Consumption-based compute costs - ANSWER Priced on a per-hour basis but billed
on a per-minute basis. For example, you are only charged for 55 minutes of usage if
the VM is deployed for 55 minutes. You are not charged for __________ capacity if
,you stop and deallocate the VM since this releases the hardware. The hourly price
varies based on the VM size and OS you select. The cost for a VM includes the
charge for the Windows operating system. Linux-based instances are cheaper
because there is no operating system license charge.
Data Disk - ANSWER A managed disk that's attached to a virtual machine to store
application data, or other data you need to keep. Is registered as SCSI drive and is
labeled with a letter that you choose. Has a maximum capacity of 4,095 gibibytes
(GiB). The size of the virtual machine determines how many
____________________s you can attach to it and the type of storage you can use to
host the disks.
Fault Domain - ANSWER A group of nodes that represent a physical unit of failure.
Defines a group of virtual machines that share a common set of hardware, switches,
that share a single point of failure. For example, a server rack serviced by a set of
power or networking switches. VMs in an availability set are placed in at least two
____________________s. This mitigates against the effects of hardware failures,
network outages, power interruptions, or software updates. Think of a
____________________ as nodes belonging to the same physical rack.
General Purpose VM type - ANSWER A, B, D families. Designed to have a balanced
CPU-to-memory ratio. Ideal for testing and development, small to medium
databases, and low to medium traffic web servers.
GPU VM type - ANSWER N family. Specialized virtual machines targeted for heavy
graphics rendering and video editing. These VMs are ideal options for model training
and inferencing with deep learning.
High Performance Compute VM type - ANSWER H family. The fastest and most
powerful CPU virtual machines with optional high-throughput network interfaces.
IaaS - ANSWER Infrastructure as a Service
Infrastructure as a Service - ANSWER An instant computing __________,
provisioned and managed over the Internet. Provides foundation-level resources on
which you deploy and maintain your own services. Includes Compute, Networking,
and Storage services.
Location - ANSWER Azure has data centers all over the world filled with servers and
disks. These are grouped into geographic regions. __________ is the term Azure
uses for the region you select for a particular service.
Memory Optimized VM type - ANSWER D, E, G, M families. Designed to have a high
memory-to-CPU ratio. Great for relational database servers, medium to large
caches, and in-memory analytics.
Operating System Disk - ANSWER Every virtual machine has one attached
____________________. That ____________________ has a pre-installed OS,
which was selected when the VM was created. This disk has a maximum capacity of
, 2,048 GiB. It's registered as a SATA drive and in Windows VMs is labeled as the C:
drive by default.
Reserved Virtual Machine Instances - ANSWER An advance purchase of a virtual
machine for one or three years in a specified region. The commitment is made up
front, and in return, you get up to 72% price savings compared to pay-as-you-go
pricing.
Scale Set - ANSWER An Azure Compute resource you can use to deploy and
manage a set of identical VMs. With all VMs configured the same, VM
____________________ are designed to support true auto-scale—no pre-
provisioning of VMs is required—and as such makes it easier to build large-scale
services targeting big compute, big data, and containerized workloads. So, as
demand goes up more virtual machine instances can be added, and as demand
goes down virtual machines instances can be removed.
Storage Optimized VM type - ANSWER L family. Designed to have high disk
throughput and IO. Ideal for VMs running databases.
Temporary Disk - ANSWER Every VM contains a ____________________, which is
not a managed disk. The ____________________ provides short-term storage for
applications and processes and is intended to only store data such as page or swap
files. Data on the ____________________ may be lost during a maintenance event
or when you redeploy a VM. During a standard reboot of the VM, the data on the
____________________ should persist. However, there are cases where the data
may not persist, such as moving to a new host. Therefore, any data on the
____________________ should not be data that is critical to the system. On
Windows virtual machines, this disk is labeled as the D: drive by default and it used
for storing pagefile.sys. On Linux virtual machines, the disk is typically /dev/sdb and
is formatted and mounted to /mnt by the Azure Linux Agent.
Update Domain - ANSWER Lets Azure perform incremental or rolling __________s
across a deployment. Contains a set of virtual machines and associated physical
hardware that can be __________ and rebooted at the same time. During planned
maintenance, only one ____________________ is rebooted at a time. By default,
there are five (non-user-configurable) ____________________, but you configure up
to twenty ____________________s.
Virtual Machine cost elements - ANSWER Compute __________ and Storage
__________. Compute __________ can be either Consumption-based or Reserved
Virtual Machine Instances (RI).
Virtual Machine disk types - ANSWER Operating System Disk, Temporary Disk,
Data Disk
Virtual Machine pricing - ANSWER Compute costs: consumption-based or Reserved
Virtual Machine Instances; Storage costs
Virtual Machine Sizing - ANSWER Once you have the name and location set, you
need to decide on the __________ of your VM. Rather than specify processing
