In which two ways does TCP differ from UDP? (Choose two.)
TCP differs from UDP primarily in two ways: it provides synchronized communication to ensure that both ends of the connection are in agreement about the state of the communication, and it provides sequence numbering of packets to ensure data is received in the correct order. These features enable reliable, ordered, and error-checked delivery of a stream of packets. UDP, on the other hand, does not offer these reliability features and is used for faster, connectionless communication.
Under which circumstance should a network administrator implement one-way NAT?
One-way NAT is used when traffic that originates outside the network must be routed to internal hosts. This configuration helps manage situations where internal hosts use private IP addresses that are not directly accessible from the internet. By implementing one-way NAT, the network administrator can translate the destination IP address of incoming packets from the outside network to the appropriate internal private IP address, allowing external sources to communicate with internal hosts. This setup is crucial for services that need to be accessed from outside the network, such as web servers or mail servers hosted internally.
Refer to the exhibit.
Which statement describes the effect of this configuration?
The configuration shown does not immediately add VLAN 10 to the VLAN database. Instead, the VLAN 10 configuration is committed and saved only when the router exits VLAN configuration mode. Until then, any 'do show vlan' command used while still in configuration mode might not show the new VLAN 10 as it hasn't been fully created and saved yet.
DRAG DROP -
Drag and drop each cable type from the left onto the type of connection for which it is best suited on the right.

A TFTP server has recently been instated in the Atlanta office. The network administrator is located in the NY office and has made a console connection to the NY router. After establishing the connection they are unable to backup the configuration file and iOS of the NY router to the TFTP server. What is the cause of this problem?
Based on the exhibit, the TFTP server has an IP address of 172.16.1.101 with a subnet mask of 255.255.255.240. This subnet mask translates to a /28 subnet, which does not align with the /29 subnet mask used on the connected routers (172.16.1.97/29). Due to this mismatch, the TFTP server likely cannot communicate properly within the network, causing the backup failure. Correcting the subnet mask on the TFTP server to match the /29 subnet of the routers should resolve the issue.
