Question 1 of 87

In which two ways does TCP differ from UDP? (Choose two.)

    Correct Answer: A, C

    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.

Question 2 of 87

Under which circumstance should a network administrator implement one-way NAT?

    Correct Answer: B

    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.

Question 3 of 87

Which destination IP address can a host use to send one message to multiple devices across different subnets?

    Correct Answer: D

Question 4 of 87

Refer to the exhibit.

Exam 100-105 Question 4

Which statement describes the effect of this configuration?

    Correct Answer: C

    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.
