Building or buying a solution? One of the things you’ll have to solve for in your exam and probably as a project manager in your organization is the determination of should you build it or should you buy it. So in this brief presentation, I’m going to show you a quick way to make make a financial decision on building or buying. In this particular approach, what you need to do is to first identify how much will it cost you to build the solution. And then once you build…

Monitoring and controlling the project work As a project manager, you’ll have to be involved with your team to monitor and control the project work. You’re working with the team to ensure accuracy and quality. So you’re comparing actual experiences to the project management plan and that is the key takeaway with monitoring and controlling work. What did you plan to do and what actually happened? This allows you to assess project performance, identify risk, and then just to maintain information about where you currently are in the project. So…

Selecting a project There may be times in your career where management calls upon you to help select a project. So in this lecture, we’re going to look at project selection, calculations and different approaches to select a project. Most of these are benefit measurements. Benefits measurements are a way of comparing the benefits of the projects. You usually have one or two or seven or eight projects and you examine, well, what are the benefits, what are the cost? And we call that a cost benefits ratio. Now the…

8_1 CDP And LLDP CDP is a Cisco probe Reactory protocol used to share information about directly connected Cisco devices. This is an OSI layer to function. If you want to enable it globally, you can use the CDP run command, and if you want to enable it per interface, you can use the Cdpenabled commands under the related interface. But CDP is active by default on most iOS versions. Okay in here, we have just two routers connected directly connected to each other. And if I type, for example,…

4_1- Spanning-Tree Protocol Overview The first slide is talking about why we need spanning tree. Ethernet frames don’t have a TTL value so they can move between swedes eternally. Because of that we can face with broadcast storms. For example, let’s say that PC one sends broadcast to our network because of that broadcast packet. Our switch takes the packet and flutes it from its all ports. This traffic comes to the switch Two. Switch two also takes the packet and flutes it from here and switch three also takes…

7_1- AAA In this section we are going to talk about Triple A which is a security feature that provides secure access to network resources. Let’s start with what is Triple A. We have three main features of play. The first one is authentication. Authentication provides users must enter username and password before accessing the devices. An authorization provides users must be authorized at various levels. For example, you may have operator users and you may have administrator level users so you can define different command line interface commands for…

5_1- Inter VLAN Routing Overview A virtual local area network defines a broadcast domain and provides easement. Management also provides isolation, as you know, and the different VLANs cannot communicate each other without a layer three device, such as a rather Firewall or layer three capability of switch. By using interval and routing, you can establish communication between different villains with a layer three device. Popular methods of the interval and routing are rather on a stick and the layer three switching router on a stick is a term frequently…

6_1- HSRP In this section we’re going to talk about HSRP protocol. A first hub redundancy protocol. FHRP is a computer networking protocol which is designed to protect the default gateway used on a subnetwork by allowing two or more routers to provide backup for the IRS. In the event of a failure of an active router, the backup router will take over the address, usually within a few seconds. In practice, such protocols can also be used to protect other services operating on a single IP address, not just…

Hyperledger Composer Demo Now what we want to do is add our protocols for web traffic, which is going to be Http and Https. Now port 80 is fine. We’re going to go ahead and leave this as the default. I’m going to add another rule. I’m going to go over here, put in Https and actually select Https and there we go. Those are the two ports that we need to have open to access, for example, web traffic to that VPC, but also any VMs inside of the…

AWS Managed Blockchain (DEMO ONLY) No support and not on the exam Alright, well, let’s talk about AWS manage blockchain in this demo. Now this is a very new service. At the time of writing, this is still in preview mode, so you need to be basically authorized to access the service. However, by the end of April, early May 2019, this should be general availability. So let’s talk about what exactly this is. So this is actually very similar to how things work essentially with IBM blockchain as a…
