...NT1330 Unit 4 Assignment 1. AD Design Replication Scenario AD Design Replication Scenario To whom it may concern: I am the IT Administrator for the company and I have been asked to give my recommendations for the Active Directory Replication Design of the two new Branches. The first I can recommend for you is that all the information that is needed for each new site is correctly documented and added to the Root Active Directory through the Active Directory sites and services. This is done because the Root AD automatically builds the inter-site replication topology based on the information provided about the new site connections. Each new site’s AD will have one each domain controller that is known as the inter-site topology generator and they are assigned to build the topology at their sites. To add two new branch offices we will need to find a strategy to design a replication process. To implement this we will need to use inter-site replication. Inter-site replication is needed when adding domain controllers located in different sites. We will also need a site link (Site link is a logical, transitive connection between two sites that allows replication to occur) protocol of Remote Procedure Call (RPC) over Internet Protocol (IP) which is the preferred choice for the replication process. This allows you to communicate with network services on various computers and also keep data secure when being transmitted by using both encryption and authentication...

...AD Design Replication Scenario To add two new branch offices we will need to find a strategy to design a replication process. To implement this we will need to use intersite replication. Intersite replication is needed when adding domain controllers located in different sites. We will also need a site link in order for replication to take place between the various locations. A site link is a logical, transitive connection between two sites that allows replication to occur. We will need to take into consider the cost, schedule, and frequency. It’s best to set the schedule for the site link during off-peak business hours. This will ensure the bandwidth is not bogged down on the WAN, due to replication traffic. Frequency will determine how often information is replicated over the site link. Before installing the new domain controllers and before we begin the replication process, we will need to setup the IP addressing or sub netting for the new locations. We will want to use subnets that reflect our current IP addressing scheme. This will be important to make sure there are connections between hosts and domain controllers as needed. Remote Procedure Calls over Internet Protocol (RPC over IP) is the preferred choice for the replication process. This allows you to communicate with network services on various computers. This will also keep data secure when in transit by using both encryption and authentication. In conclusion this will be a process needing to...

...Active Directory Design Scenario To effectively achieve this I need to know and understand everything about Active Directory Domain Services. When designing and implementing an Active Directory domain, you need to think about the placement of your global catalog servers. The global catalog is the master index of objects within an Active Directory forest. The global catalog serves as a quick search tool to locate objects within a forest. Every domain must have at least one global catalog server. The first domain controller (DC) installed into a domain automatically serves as that domain's global catalog server by default. As the size of your forest grows, there may become a need to configure additional global catalog servers throughout the forest. There are two main issues to consider when placing global catalog servers into a domain. The first is the traffic levels and the second is the location of infrastructure servers. As the forest gets larger, so does the global catalog. As the global catalog expands, the amount of replication traffic it generates increases. Global catalog servers replicate with each other. This is separate replication traffic from that used to support Active Directory itself. From an overall perspective of the forest, when fewer global catalog servers are deployed in a forest, there will be less replication traffic, but it will cause more query traffic. Conversely, deploying more global catalog servers in a forest will cause more replication traffic, but...

...Week 4 – Active Directory Design Scenario Since the two new braches office will be directly connected to main office you can configure hub and spoke topology. I would also recommend in hub site to have minimum two DC for redundancy. In the event of failure if second DC does not exist irrespective of OS version AD replication will be down totally. At least in the hub site you should have additional DC if not present. Branch 1 – For this site I would recommend setting up another line to the main hub to remove single point of failure. Also setting a backup for branch 1 located at main site and if possible at branch 2. A two way trust will need to be set up to support backup at main site/branch 2 if servers fail at branch 1. To support AD replication I would use two way trust network. Branch 2 – With branch 2 being located at a remote site I would recommend setting a VSAT system to remove the single point of failure. With the slow speed at this branch it would not make for a very good backup site. I would use two way trusts for replication of services. *Recommendations for Optimum Performance For Active Directory replication, a rule of thumb is that a given domain controller that acts as a bridgehead server should not have more than 50 active simultaneous replication connections at any given time in a replication window. (This was determined on a reference server that had four Pentium III Xeon processors with 2 gigabytes (GB) of RAM and 2 megabytes (MB) of L2 cache.) Adjusting...

...AD Design Scenario: FSMO Role & GC Placement 1. Is there a one to one relationship between the server roles and the number of servers that house them? 2. How many DC’s are in your domain? 3. What servers/server are global catalog servers? 4. How many computers will be hosting the FSMO roles? 5. Will the roles be on one DC or multiple? The Schema Master and Domain Naming Master should reside on the same server, and that machine should be a Global Catalog server. Since all three are, by default, on the first domain controller installed in a forest, then you can leave them as they are. The Infrastructure Master should not be on the same server that acts as a Global Catalog server. The reason for this is the Global Catalog contains information about every object in the forest. When the Infrastructure Master, which is responsible for updating Active Directory information about cross domain object changes, needs information about objects not in its domain, it contacts the Global Catalog server for this information. If they both reside on the same server, then the Infrastructure Master will never think there are changes to objects that reside in other domains because the Global Catalog will keep it constantly updated. This would result in the Infrastructure Master never replicating changes to other domain controllers in its domain. I also recommend that the PDC Emulator and RID Master be on the same server. This is not mandatory like the Infrastructure...

... Johny Jose National Institute of Technology Karnataka, Surathkal, India ABSTRACT Delay Tolerant Networks (DTNs) have evolved from Mobile Ad Hoc Networks (MANET). It is a network, where contemporaneous connectivity among all nodes doesn’t exist. This leads to the problem of how to route a packet from one node to another, in such a network. This problem becomes more complex, when the node mobility also is considered. The researchers have attempted to address this issue for over a decade. They have found that communication is possible in such a challenged network. The design of routing protocol for such networks is an important issue. This work surveys the literature and classifies the various routing approaches. discontinuity in the network. There are also methods that have employed additional mobile nodes, to provide better message delivery. Researchers are even exploring how the social interaction of humans can be utilized for routing in a DTN. This survey has made an extensive study of the various routing strategies taken by the researchers in the past few years. We have classified them based on the type of knowledge used for routing. 2. FLOODING BASED APPROACHES Knowledge about the network helps in deciding the best next hop. It can happen that the network has absolutely no knowledge about the network. In such a scenario, all nodes are made relay nodes. Such schemes are called epidemic routing schemes. The basic concept of epidemic routing is to flood the packets...

You should consider reducing the TTL of the SOA record in the DNS zone properties page. D. You should consider disabling updates in the DNS zone properties page. Answer: B Explanation: In the scenario you should enable scavenging through the zone properties because scavenging removes the outdated DNS records from the DNS zone automatically. You should additionally note that patience would be required when enabling scavenging as there are some safety valves built into scavenging which takes long to pop.

...and finances. Each supply chain node has its own customers, suppliers and inventory management strategies, demand arrival process and demand forecast methods, items mixture and dedicated internal resources. In this context, each supply chain manager aims to reach the key objective of an efficient supply chain: ‘the right quantity at the right time and in the right place’. To this end, each supply chain node (suppliers, manufacturers, distribution centers, warehouses, stores, etc.) carries out various processes and activities for guarantying goods and services to final customers. The competitiveness of each supply chain actor depends by its capability to activate and manage change processes, in correspondence of optimistic and pessimistic scenarios, to quickly capitalize the chances given by market. Such capability is a critical issue for improving the performance of the ‘extended enterprise’ and it must take into account the complex interactions among the various supply chain nodes. The evaluation of correct trades-offs between conflicting factors, such as inventory reduction and fill rates, customers’ satisfaction and transportation cost, sales loss and inventory costs, resources management and internal costs, are (among others) the most important tasks of a competent...

Nike was founded by Bill Bowerman, the legendary University of Oregon track and field coach, and Phil Knight, a University of Oregon business student and middle-distance runner under Bowerman. The partnership began in 1962 as Blue Ribbon Sports (BRS); their first-year sales totalled $8,000. In 1972 BRS changed its name to Nike, named after the Greek winged goddess of victory. Nike employs 22,000 people worldwide, from Nike World Headquarters in Oregon. With 1,500 employees working at the Laakdal Customer Service Centre, Belgium has the most employees of any EMEA (Europe, Middle East and Africa) country. The Netherlands is a close second, with 1,200 employees working at the European HQ in Hilversum. Nike is the number one athletic footwear company in the US and the number two American brand in terms of name recognition among overseas consumers, a status shared with IBM and second only to Coca-Cola. This high degree of recognition is probably one of the main reasons Nike has been so immensely successful. For the 2001 fiscal year sales...
