*Which three addresses are valid public addresses? (Choose three.)* 198.133.219.17 192.168.1.245 10.15.250.5 128.107.12.117 192.15.301.240 64.104.78.227

198.133.219.17 128.107.12.117 64.104.78.227

*How many hosts are addressable on a network that has a mask of 255.255.255.248?* 2 6 8 14 16 254

6

*Which three statements characterize UDP? (Choose three.)* UDP provides basic connectionless transport layer functions. UDP provides connection-oriented, fast transport of data at Layer 3. UDP relies on application layer protocols for error detection. UDP is a low overhead protocol that does not provide sequencing or flow control mechanisms. UDP relies on IP for error detection and recovery. UDP provides sophisticated flow control mechanisms.

*Which two roles can a computer assume in a peer-to-peer network where a file is being shared between two computers? (Choose two.)* client master server slave transient

client server

*What important information is added to the TCP/IP transport layer header to ensure communication and connectivity with a remote network device?* timing and synchronization destination and source port numbers destination and source physical addresses destination and source logical network addresses

destination and source port numbers

*What type of IPv6 address is FE80::1?* loopback link-local multicast global unicast

link-local

*When planning for network growth, where in the network should packet captures take place to assess network traffic?* on as many different network segments as possible only at the edge of the network between hosts and the default gateway only on the busiest network segment

on as many different network segments as possible

*What is the TCP mechanism used in congestion avoidance?* three-way handshake socket pair two-way handshake sliding window

sliding window

*Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?* to identify the broadcast address of the destination network to identify the host address of the destination host to identify faulty frames to identify the network address of the destination network

to identify the network address of the destination network

*What is the function of the HTTP GET message?* to request an HTML page from a web server to send error information from a web server to a web client to upload content to a web server from a web client to retrieve client email from an email server using TCP port 110

to request an HTML page from a web server

*In what two situations would UDP be the preferred transport protocol over TCP? (Choose two.)* when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated when a faster delivery mechanism is needed when delivery overhead is not an issue when applications do not need to guarantee delivery of the data when destination port numbers are dynamic

when a faster delivery mechanism is needed when applications do not need to guarantee delivery of the data
