On an IP network, all hosts must be able to handle a packet size of at least how many
bytes? -
ANS✔✔>>>>576
What happens to a datagram marked as "do not fragment" if it must be transmitted
across a network segment with a maximum transmission unit field (MTU) smaller
than the datagram? -
ANS✔✔>>>>The transmitting network device will drop the
datagram, and notify the source.
Which IP packet frame field ensures that the gateways handling
a datagram agree on the datagram's format? -
ANS✔✔>>>>Version
Which IP packet bits does open shortest path first (OSPF) use
to provide Type of Service (ToS) routing? -
ANS✔✔>>>>Delay, throughput, reliability, and cost (D-T-R-
C) bits.
Address resolution protocol (ARP) requests are sent as which type of
,Ethernet frame? - ANS✔✔>>>>Broadcast
Which IP protocol allows a diskless workstation to contact a server and obtain an IP
address? - ANS✔✔>>>>Reverse address resolution protocol (RARP).
Which statement best describes proxy address resolution protocol (ARP)? -
CORRECT
ANSWER>>>>Proxy ARP allows a router to answer an ARP request on behalf of a
remote host.
How does a diskless workstation identify itself when requesting an
IP address using reverse address resolution protocol (RARP)? -
ANS✔✔>>>>By its media access control (MAC) address.
Which network segment hosts respond to an address resolution protocol (ARP)
request? - ANS✔✔>>>>Only the target host responds
Which address resolution protocol (ARP) feature allows
the local host to maintain a mapping of recently
discovered IP-to-media access control (MAC)
addresses? - ANS✔✔>>>>The ARP cache
What happens first when an IP host needs to resolve an IP address to a
media access control (MAC) address? - ANS✔✔>>>>The sending
host looks in its address resolution protocol (ARP) cache for the
necessary mapping.
,Which is a true statement concerning user datagram protocol (UDP)? -
CORRECT ANSWER>>>>UDP servers must listen for service requests on well
known ports, or else the transactions may fail.
Which three of the following applications utilize user datagram
protocol (UDP)? (Choose three.) - ANS✔✔>>>>Trivial file
transfer protocol (TFTP).
Simple network management protocol (SNMP).
Domain Name System (DNS).
How does the user datagram protocol (UDP) support multiple application
destinations on the same host? - ANS✔✔>>>>It carries port numbers in its
header, used to logically address a destination application.
Which best describes the user datagram protocol (UDP) demultiplexing process?
- CORRECT ANSWER>>>>UDP uses port numbers to allow multiple
applications to communicate simultaneously on the same host.
Which transmission control protocol (TCP) function forces data delivery before
filling the transmit buffer? - ANS✔✔>>>>Push
Which three choices are transmission control protocol (TCP) features? (Choose
three.) - ANS✔✔>>>>Flow control.
Packet error recovery.
Demultiplexing multiple applications.
Which best describes transmission control protocol's (TCP) use of the Window
header field? - ANS✔✔>>>>It is bidirectional, so both ends can control data flow.
, Which addresses combine to create a transmission control protocol (TCP) socket? -
CORRECT ANSWER>>>>IP and port.
Which portion of the transmission control protocol (TCP) header specifies the next
sequence
number the receiver expects from the connection source? - CORRECT
ANSWER>>>>Acknowledgment number.
How does the transmission control protocol (TCP) receiver control the data
flowing from the source? - ANS✔✔>>>>It sets the receive window size with
each ACK segment it returns.
Which three parts of the transmission control protocol (TCP) header help the
protocol ensure
reliable communications between applications? (Choose three.) - CORRECT
ANSWER>>>>ACK control bits
Sequence numbers
Checksum
Which statement best describes transmission control protocol's (TCP) use of
sequence numbers?
- ANS✔✔>>>>They identify the sequence number of the first data byte in
the segment.
How does a transmission control protocol (TCP) process handle a
failed connection? - ANS✔✔>>>>It sends an RST segment when the
maximum retry count is exceeded.
