A security group acts as a virtual firewall that controls the traffic for one or more virtual server instances. A security group is a collection of rules that specify whether to allow or deny traffic for an associated instance. You can associate an instance with one or more security groups and edit the security group rules An Access Control List (ACL) can manage (that is, it can allow or deny) inbound and outbound traffic for a subnet. An ACL is stateless, which means that inbound and outbound rules must be specified separately and explicitly. Each ACL consists of rules, based on a source IP, source port, destination IP, destination port, and protocol. Note : Security Groups control traffic at the virtual service instance level and n Access Control List (ACL) control the traffic at subnet level.

Explanation

Site reliability engineering (SRE) uses software engineering to automate IT operations tasks - e.g. production system management, change management, incident response, even emergency response - that would otherwise be performed manually by systems administrators (sysadmins). The principle behind SRE is that using software code to automate oversight of large software systems is a more scalable and sustainable strategy than manual intervention - especially as those systems extend or migrate to the cloud. SRE can also reduce or remove much of the natural friction between development teams who want to continually release new or updated software into production, and operations teams who don't want to release any type of update or new software without being absolutely sure it won't cause outages or other operations problems. As a result, while not strictly required for DevOps, SRE aligns closely with DevOps principles and can be play an important role in DevOps success

Explanation

Correct Answer : IBM API Connect® Service provides API creation and management with security-rich features and centralized governance. You can use IBM API Connect for IBM Cloud to quickly create APIs for microservices based on Node.js and Java runtimes. When APIs are hosted on API Connect: Consumers can locate, understand, learn, and experiment with the APIs they need before committing to use them. They can also self-subscribe to them using revocable keys. Providers can hide the exact locations of API implementations, enable version-based routing, and throttle inbound requests to the API on a per-consumer basis. These capabilities are helpful while packaging data for partners. Consumers and providers can track use and response times, which allows them to tie resource use to their business model. In-Correct Answers IBM Event Streams for IBM Cloud is a high-throughput message bus built with Apache Kafka and was previously known as Message Hub. In Event Streams, applications send data by creating a message and sending it to a topic. It uses availability support from IBM Kubernetes services to maintain high availability and resilience. Integration is available with IBM Cloud services as well as Watson Internet of Things® (IoT). Key Features Fully Managed: Built on Apache Kafka, IBM Cloud Event Streams is a fully managed service. Intuitive UX: Deploy your Event Streams in minutes using the benefits of IBM Design Thinking. Event-Driven: Use integrations with IBM Cloud services like Watson IoT platform, IBM Streaming Analytics, and IBM Cloud Functions to easily create your event-driven architecture. IBM App Connect® is a powerful all-in-one tool for easily connecting apps, integrating data, building APIs, and acting on events. App Connect can connect any endpoint, map your data, and move data fast. With IBM App Connect, you can reliably access and combine data assets across all your enterprise applications, databases, and systems and expose them as APIs. You can connect to any application or endpoint, from the latest SaaS apps to mainframe systems. IBM App Connect allows you to connect applications together using a common platform. It enables you to build automation triggers between applications and automate workflows and integrate data using the included 75+ connectors and 50+ templates. Key Features Intuitive Development Tools: Easily create APIs, thoroughly test them, then share them with others both inside and outside your organization. Easy Yet Powerful Security: Use pre-defined security policies to protect your API or customize your own. Lifecycle Management: Manage the entire lifecycle of your APIs for your internal team, external consumers, and third parties. Customizable Developer Portal: Share your APIs with other developers using the built-in fully-customizable portal. The portal includes the ability to communicate with API consumers using a variety of modalities including blogs, forums, and messaging. IBM® MQ on Cloud provides enterprise-grade messaging capabilities to allow the flow of information between different applications. This service is fully managed so you can focus on integrating MQ applications rather than upgrades and patches. Key Features Deduplication: Messages are delivered without duplicates. Connectivity: Connectivity issues are handled by MQ. Encryption: End-to-end data encryption is used to ensure the security of your data. [Exam Tips] Remember following points: If you need to create, secure, and manage APIs use API Connect If you need to connect, copy, and sync application data across platforms use APP Connect If you need to deliver reliable, secure messaging, either on-premises or over the cloud use MQ If you need to build adaptive smart apps that react to events as soon as they happen use IBM Event Streams
