Exadata DB Systems 52.Which Oracle Cloud Infrastructure (OCI) capability allows you to set up alerts to notify you if a budget forecast is to be exceeded or spending surpasses a certain amount? Budget 53.Which two Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) firewall features can be used to control traffic? Network Security Groups VNIC Metrics VCN Flow Logs Security Lists 54. Which OSI layer traffic is supported by the Oracle Cloud Infrastructure (OCI) Network Load Balancer? Layer 7 (Application) 55.Which two statements are valid regarding Virtual Cloud Network (VCN) peering between two VCNs? Peered VCNs can exist in the same OCI region. Peered VCNs can exist in different OCI regions. Oracle Cloud Infrastructure (OCI) provides two load balancing services — Flexible Load Balancer that functions at Layer 7 of the OSI model and Network Load Balancer that works at Layer 3/Layer 4 of the OSI model. Oracle Cloud Network Load Balancer (NLB) provides automated traffic distribution from one entry point to multiple backend servers in the Oracle Cloud virtual cloud network (VCN). The NLB operates at the connection level and load balances incoming client connections to healthy backend servers based on Layer 3/Layer 4… In this blog post we will discuss the following topics: Oracle Cloud Infrastructure recently has introduced the Flexible Network Load Balancer new feature on 24th March 2021. Load Balancer provides automatic distribution of traffic from one point to multiple backend sets. In Load Balancer you can create your choice of a public or private IP address. The Load Balancer can reduce your maintenance window by draining traffic from an unhealthy application. Overview of Network Load BalancerNetwork Load Balancer provides the benefits of flow high availability, source and destination IP addresses, and port preservation. It is designed to handle volatile traffic patterns and millions of flows, offering high throughput while maintaining ultra-low latency.

The public load balancer has a public IP address and The private load balancer has an IP address that is visible within your VCN. 1. Public Network Load Balancer:
2. Private Network Load Balancer:

Backend Set: A logical entity defined by a list of backend servers, a load balancing policy, and a health check policy. 3. Health Check: A health check is a test to confirm the availability of backend servers.
4. Health Status: It indicates the Health of your Network Load Balancer and its Components. 5. Listener: A logical entity that checks for incoming traffic on the network load balancer’s IP address.
6. Network Load Balancing Policy: It tells the load balancer how to distribute the incoming traffic to the backend server.
7. Regions and Availability Domains: The Network Load Balancer service manages application traffic across availability domains within a region. Note: Check our Blog to know more about what Is Region, Availability Domain (AD) 8. Subnet: A subnet consists of a contiguous range of IP addresses that do not overlap with other subnets in the VCN. Note: Check our Blog to know more about what Is Oracle Cloud: Create VCN, Subnet, Firewall 9. Virtual Cloud Network (VCN): A private network that you set up in the Oracle data centers, with firewall rules and specific types of communication gateways. Note: Check our Blog to know more about what Is Networking In Oracle Cloud (OCI): VCN, Subnet, Gateways, Peering, Transit Routing Network Load Balancer Limits:Every Load balancer has the below configuration limits:
Network Load Balancer PoliciesYou can apply Network Load Balancer resource policies to control traffic distribution to your backend servers. Network Load Balancer service supports three primary network load balancer policy types:

Which OSI layer traffic is supported by the Oracle cloud infrastructure and network load balancer?You should use OCI Network Load Balancer when you require a low-latency, high-throughput, layer-4 (TCP/UDP/ICMP) load balancing solution.
Which OSI layer traffic is supported by the Oracle cloud infrastructure OCI network load balancer mark for review?An application load balancer works on layer 7, so it supports both HTTP and HTTPS. It can distribute HTTP and HTTPS traffic based on host-based or path-based rules.
What OSI layer is load balancer?An Layer 7 load balancer works at the application layer—the highest layer in the OSI model—and makes its routing decisions based on more detailed information such as the characteristics of the HTTP/HTTPS header, message content, URL type, and cookie data.
Is load balancer a layer 3?Server load balancer (SLB) provides traffic load distribution functionality for this release of the switch firmware. Load distribution can be performed at layer 2 or layer 3 of the networking protocol stack. This release provides support for only load distribution at layer 3.
