In telecom closet 2, from the punch down block, to the switches, to the wall plates, and on to the offices workstation, plus one shared printer, cabling will change to Cat 5e UTP, using 1000 Base-T technology, achieving a throughput of 1000Mbps. A safety feature on Ethernet Lans, is its access method, CSMA/CD. CSMA/CD, means that your NIC checks the network to make sure it is not busy before transmitting, if two nodes do transmit at the same time having a collision, it will send out packets to inform other nodes of a data collision, then the NIC waits for the network to be inactive before retransmitting. On the
For security, a constrained delegation must be impersonated in a Windows Server 2003 or higher domain functional level running Kerberos. The forest functional level must be in a Windows Server 2003 or higher as well. The commands adprep / rodcprep must be run once to update the forest permissions on all DNS application directory partitions. In a RODC the changes need to be performed in the Main Domain Controller. The RODC absorb this information and updates its database.
What is incorrectly configured? the IP address of the S0/0/0 interface at R1 9. Refer to the exhibit. Which summarization should R1 use to advertise its networks to R2? 192.168.0.0/22 10.
Is there a firewall configured on your computer, is your firewall block ing ports, if you turn off the firewall does it resolve your problem? If not move onto the Network Layer; can you ping your default gateway, are your IP settings correct, can you trace a well-known IP/DNS address/URL, and finally has your network adaptor b een assigned an APIPA address? You then move to the data link layer. Is the light lit on your network interface card, is your NIC inserted/installed correctly, is the NIC d isabled in the device 4.4 review 1. The divide-and-conquer
This network has enough switches to accommodate the network segregation to support creating VLANs (Team A, 2008). However, in keeping with the goal of standardization in mind the patch panel should also be replaced. Corporate headquarters in San Jose has two, 24-port switches that connect the inter-office network. Two gateway switches connect and translate communications between the LAN and the Satellite and between the R&D LAN and the inter-office LAN. Corporate headquarters could benefit from replacing the 24-port hub with a 24-port switch.
