11. What exactly do Azure's Network Security Groups do?

For various Azure resources, a network security group is a collection of security rules (access control list of rules) that permit or disallow incoming and outgoing network traffic. NSGs can be used to link subnets or specific NICs linked to a subnet so that the rules are applied to every solitary VM in that subnet. For each rule, you can specify the host, the protocol, the sender and receiver addresses, as well as other details.

12. Define Azure table storage.

The Windows Azure Table data storage holds enormous amounts of structured data. A NoSQL service, it accepts calls from within and outside the Windows Azure cloud.

• Table: A table is a collection of things. A single table could indeed contain entities with different sets of characteristics because tables do not start imposing a format on their constituent entities. A single account contains many tables.
• Entity: An entity is a group of attributes, much like a database entry. The size of a single entity can reach 1MB.
• Properties: A property is a pair of name values. There are a maximum of 252 properties per object. Each entity also has three system properties: a partition key, a row, and a size.

13. Describe Azure's Site Recovery feature.

Site Recovery is a provider that guarantees efficient business operations by maintaining corporate workloads and apps online during outages. With the aid of physical and virtual machines, this Azure feature operates in a way that copies activities from the primary site to a secondary location (VMs). You move to the backup location, where you can access the apps when your primary location goes down. When it has been repaired, you can go back to the main location. Replication is ensured for Azure VMs, on-site VMs, Azure Stack VMs, and physical servers by Site Recovery.

14. Does Traffic Manager support sticky sessions?

Clients are directed to the most appropriate service endpoint using DNS responses because the Traffic Manager operates at the DNS level. Additionally, since clients are able to bypass Traffic Manager and connect to the service endpoint, the HTTP traffic between both the client and the server is hidden from Traffic Manager. Additionally, the source IP address of the DNS query that the Traffic Manager receives belongs to the recursive DNS service rather than the client. The traffic Manager is consequently unable to keep track of specific clients or establish persistent sessions. All DNS-based traffic control systems, including Traffic Manager, are subject to this restriction.

15. What Azure feature can be applied to prevent a heavy application load in the event of flow-level no-man assistance?

The use of VM Scale sets, which specify the specifications for providing a new VM when there is an increase in application load, is the solution to this issue. A load-balanced group of VMs can be created and managed by developers using Azure VM Scale Sets. Depending on demand or a predetermined timeline, the number of virtual machine instances can be automatically increased or decreased. With the aid of scale sets, programmers can make it easier to build large-scale applications that can handle enormous amounts of data, workloads, and compute demands. They enable developers to manage, update, and configure big VMs and guarantee the high availability of the applications.

Most Common  Azure Architect FAQs

1. What different types of cloud deployment models are there?

The three cloud-based deployment models are as follows:
