Protocol Independent Multicast PIM, which is used between multicast-capable routers, advertises group membership across a routing domain by constructing multicast distribution trees. PIM builds shared distribution trees on which packets from multiple sources are forwarded, as well as source distribution trees, on which packets from a single source are forwarded. The distribution trees change automatically […]

Choosing the Right Cable Pinouts For the exam, you should be well prepared to choose which type of cable (straight-through or crossover) is needed in each part of the network. The key is to know whether a device acts like a PC NIC, transmitting at pins 1 and 2, or like a switch, transmitting at […]

This chapter covers the following official AWS Certified SysOps Administrator – Associate (SOA-C02) exam domain: Domain 6: Cost and Performance Optimization (For more information on the official AWS Certified SysOps Administrator – Associate [SOA-C02] exam topics, see the Introduction.) In the preceding chapter, you focused on strategies and tools to optimize the costs of your […]

Experience Cloud licensing and sharing The license type used with Experience Cloud can have an impact on sharing and the way record access works for users. In a nutshell, the Customer Community license type doesn’t support roles, and sharing sets are used instead of sharing rules. Sharing sets are used to grant record access to any […]

Straight-Through Cable Pinout 10BASE-T and 100BASE-T use two pairs of wires in a UTP cable, one for each direction, as shown in Figure 2-9. The figure shows four wires, all of which sit inside a single UTP cable that connects a PC and a LAN switch. In this example, the PC on the left transmits […]

THE AWS CERTIFIED ADVANCED NETWORKING – SPECIALTY EXAM OBJECTIVES COVERED IN THIS CHAPTER MAY INCLUDE, BUT ARE NOT LIMITED TO, THE FOLLOWING: Task Statement 3.1: Maintain routing and connectivity on AWS and hybrid networks. Industry-Standard Routing Protocols Used in AWS Hybrid Networks When creating a hybrid network with AWS, a standards-based routing protocol is required […]

Multicast Distribution Trees A multicast distribution tree (MDT) represents the path that multicast data takes between the routers that connect sources and receivers. The multicast software builds different types of trees to support different multicast methods. A source tree represents the shortest path that the multicast traffic takes through the network from the sources that transmit […]

Note Changing the query interval can severely impact multicast forwarding. When a multicast host leaves a group, a host that runs IGMPv2 or later sends an IGMP leave message. To check if this host is the last host to leave the group, the software sends an IGMP query message and starts a timer that you […]

Further Reading For additional information on the AWS shared responsibility model and the underlying foundation of AWS security, please look at the following resources: Exam Readiness Drill – Chapter Review Questions Apart from a solid understanding of key concepts, being able to think quickly under time pressure is a skill that will help you ace […]

Breaking Down a UTP Ethernet Link Note If available, find a nearby Ethernet UTP cable and examine the connectors closely. Look for the pin positions and the colors of the wires in the connector. To complete the physical link, the nodes each need an RJ-45 Ethernet port that matches the RJ-45 connectors on the cable so […]
