...Tell me about yourself. My name is . I attend University of New York. I have completed the associate degree program of Network System Administration. I am pursing to finish the B.A. degree in Network Communication Management in June, and concentration in Cisco. I am 33, no kids, dedicated and ambitious in completing the B.A. degree, and initiating my career in the Network/IT field. My hobbies are working out, studying and preparing myself for future exams, and mastering my hands-on skills in configuring Cisco devices. I also like researching on future technology. I have a passion for sports, computers, and network infrastructure. Right now I am building a wired/wireless LAN in my home to practice on future exams. WHAT DID YOU EJOYED MOST/LEAST ABOUT YOUR PREVIOUS JOB? WHY? Meeting new people, and working with them and witness how they think and reacted in certain situation. That allowed me to experience and witness what to do when certain situations approached at any given time. The most I enjoyed about my previous job was they allowed me to do so many things. Why? My manager called me a floater. Both of them informed my position wasn’t created for other interns, because they both noticed I don’t like to stand still, I like to be mobile and eager to learn. When I started out I wondered why I was in helpdesk, but helped the remote department upgrade PC components and OS, upgrading routers configuration templates. I did this for 6 months. I went to my manager and asked can...

...Study Guide CISCO SYSTEMS NETWORKING Academy CCNA 2 Chapter 1 WANs and Routers One major characteristic of a wide-area network (WAN) is that the network operates beyond the local LAN's geographic scope. It uses the services of carriers, such as regional Bell operating companies (RBOCs), Sprint, and MCI. WANs use serial connections of various types to access bandwidth over wide-area geographies. By definition, the WAN connects devices that are separated by wide areas. WAN devices include the following: • • • • • • Routers, which offer many services, including internetworking and WAN interface ports Switches, which connect to WAN bandwidth for voice, data, and video communication Modems, which interface voice-grade services and channel service units/digital service units Channel service units/data service units (CSUs/DSUs) that interface T1/E1 services and Terminal Adapters/Network Termination 1 (TA/NT1s) TA/NT1s that interface Integrated Services Digital Network (ISDN) services Communication servers, which concentrate on dial-in and dial-out user communication Concept Questions 1. A WAN is used to interconnect local-area networks (LANs) that are typically separated by a large geographic area. A WAN operates at the OSI reference model physical and data link layers. The WAN provides for the exchange of data packets/frames between routers/bridges and the LANs that they support. Draw a WAN that includes three LANs. 1 of 116 CCNA 2 Chapter 1 WANs and Routers 2.

...CCNA Exploration 2: Chapter 2 toets antwoorden / CCNA Routing Protocols and Concepts exam 2 answers CCNA Exploration 2: Routing Protocols and Concepts Chapter 2 Exam Answers 1. What happens to a static route entry in a routing table when the outgoing interface is not available? The route is removed from the table. The router polls neighbors for a replacement route. The route remains in the table because it was defined as static. The router redirects the static route to compensate for the loss of the next hop device. 2. The routers in the diagram use the subnet assignments shown. What is the most efficient route summary that can be configured on Router3 to advertise the internal networks to the cloud? 192.1.1.0/26 and 192.1.1.64/27 192.1.1.128/25 192.1.1.0/23 and 192.1.1.64/23 192.1.1.0/24 192.1.1.0/25 192.1.1.0/24 and 192.1.1.64/24 [pic] 3. Hosts on two separate subnets cannot communicate. The network administrator suspects a missing route in one of the routing tables. Which three commands can be used to help troubleshoot Layer 3 connectivity issues? (Choose three.) ping show arp traceroute show ip route show interface show cdp neighbor detail 4. Refer to the exhibit. How will packets destined to the 172.16.0.0 network be forwarded? Router1 will perform recursive lookup and packet will exit S0/0.

...IT, Web Routing Name: Institution: Routing A router is a network device capable of passing data between two networks. The most basic reason for using a router is to connect a LAN to the internet (Lowe, 2013). A bridge on the other hand sits between two types of networks, for example between an Ethernet and wireless (Pomerleau, 2009) Routers can be helpful under the following circumstances. To begin with, routers are capable of connecting different network architectures such as Ethernet and Token Ring networks and so if it is expected that the LAN network in our case will need to use different network architectures in the future, then routers will be best choice. Second, a router is more efficient than a bridge because a router will process information that is specifically addressed to it where as a bridge processes all messages it receives. Therefore, a router would increase network data processing speed thus will end up with an efficiently working network when using a router than when using a bridge. Next, routers are advantageous in circumstances when an organization needs to communicate to the external environment and therefore routers are capable of connecting to a Wide Area Network (WAN) such as the internet (Ogletree 2004). The capacity to connect to the external environment enables the organization to be in contact to the government for information on taxation as well as connection to customers, suppliers and even competitors. Furthermore, routers are efficient...

...Main functions of the McAfee Web Gateway appliance Filtering web traffic is a complex process. The main functions of the appliance contribute to it in different ways: • Filtering web objects — Special anti-virus and anti-malware functions on the appliance scan and filter web traffic and block web objects when they are infected. Other functions filter requested URLs, using information from the Global Threat Intelligence™ system, or do media type and HTML filtering. They are supported by functions that do not filter themselves, but do such jobs as counting user requests or indicating the progress made in downloading web objects. • Filtering users — This is done by the authentication functions of the appliance, using information from internal and external databases and methods such as NTLM, LDAP, RADIUS, Kerberos, and others. In addition to filtering normal users, the appliance also gives you control over administrator rights and responsibilities. • Intercepting web traffic — This is a prerequisite for any filtering of web objects or users. It is achieved by the gateway functions of the appliance, using different network protocols, such as HTTP, HTTPS, FTP, Yahoo, ICQ, and Windows Live Messenger. As a gateway, the appliance can run in explicit proxy mode or in transparent bridge or router mode. • Monitoring the filtering process — The monitoring functions of the appliance provide a continuous overview of the filtering process. They include a dashboard, displaying...

...(Name) (Instructors’ name) (Course) (Date) Network Management and Security A telecommunication Management Network, commonly known as TMN, is an infrastructure that provides interfaces for connection between several types of operating systems and telecommunications equipment, so as to manage the telecommunication service and network. This is from Glenn Warnock and Nathoo Amin (215). Also, it enables the functioning of the management information, which is exchanged through these interfaces. On the other hand, 5620 SAM is widely used for developing distributed systems, as it provides the infrastructure for interoperability of several object oriented management applications. With this application, the 5620 enables applications of operating systems to interoperate with the service access manager, allowing it to provide connections, isolate and manage network issues across an Alcatel network (225). With this, users can access management information transparently and independent of the hardware and software platform. This therefore enhances the portability of applications, which are developed across the multiple platforms of management. The principles and concepts of the TMN that can be matched with the features and functions of the 5620 platforms include the specification translation and the interaction translation. Redundancy is also an important feature. It is the automatic transfer of data network to stand by, and protects the network against hardware failure, software...
