What two things will happen if a router receives an ICMP packet which has a TTL value of 1 and the destination host is several hops away? (Choose two.)
The router will discard the packet. @
The router will decrement the TTL value and forward the packet to the next router on the path to the destination host.
The router will send a time exceeded message to the source host. @
The router will increment the TTL value and forward the packet to the next router on the path to the destination host.
The router will send an ICMP Redirect Message to the source host.


Refer to the exhibit. Why would the response shown be displayed after issuing the command ping 127.0.0.1 on a PC?
The IP settings are not properly configured on the host.
Internet Protocol is not properly installed on the host. @
There is a problem at the physical or data link layer.
The default gateway device is not operating.
A router on the path to the destination host has gone down.


How many bits make up an IPv4 address?
128
64
48
32 @


Refer to the exhibit. A network administrator discovers that host A is having trouble with Internet connectivity, but the server farm has full connectivity. In addition, host A has full connectivity to the server farm. What is a possible cause of this problem?
The router has an incorrect gateway.
Host A has an overlapping network address.
Host A has an incorrect default gateway configured.
Host A has an incorrect subnet mask.
NAT is required for the host A network. @


What three facts are true about the network portion of an IPv4 address? (Choose three.)
identifies an individual device
is identical for all hosts in a broadcast domain @
is altered as packet is forwarded
varies in length @
is used to forward packets @
uses flat addressing


What is a group of hosts called that have identical bit patterns in the high order bits of their addresses?
an internet
a network @
an octet
a radix


What is the network address of the host 172.25.67.99 /23 in binary?

Refer to the exhibit. A network administrator has to develop an IP addressing scheme that uses the 192.168.1.0 /24 address space. The network that contains the serial link has already been addressed out of a separate range. Each network will be allocated the same number of host addresses. Which network mask will be appropriate to address the remaining networks?
