destination route information.
What does
the command "IP name-server 255.255.255.255" accomplish?
-
A. It
sets the domain name lookup to be a local broadcast.
-
B. This
is an illegal command.
-
C. It
disables domain name lookup.
-
D. The
command is now defunct and has been replaced by "IP
server-name ip any"
Ans A
By default
DNS is enabled on a router with a server address of
255.255.255.255, which provides for a local broadcast.
As a
system administrator, you need to provide your routers with a
Domain Name System (DNS) server. How many DNS servers can you
specify with one command?
Ans A
You can only
specify six name servers in one command. The syntax is "IP
name-server server-address1 [[ server-address2
]...server-address6]. You must also enable
DNS.
How would
you configure one host name that points to two IP addresses?
-
A. IP
host jacob 1.0.0.5 2.0.0.8
-
B. IP
jacob 1.0.0.5 2.0.0.8
-
C. IP
host jacob 1.0.0.5
-
D. IP
host duplicate "all"
Ans A
The correct
syntax is IP host name [ TCP-port-number ] address [ address
]..... So, "IP host P1R1 1.0.0.5 2.0.0.8" is the correct choice.
"IP host jacob 1.0.0.5" only points the host name jacob to one
IP address--1.0.0.5.
The
following selections show the command prompt and the
configuration of the IP network mask. Which two are correct?
-
A.
Router#term IP netmask-format { bitcount | decimal |
hexadecimal }
-
B.
Router(config-if)#IP netmask-format { bitcount | decimal |
hexadecimal }
-
C.
Router(config-if)#netmask-format { bitcount | decimal |
hexadecimal }
-
D.
Router#ip netmask-format { bitcount | decimal | hexadecimal
}
Ans A
& B
Router#term
IP netmask-format { bitcount | decimal | hexadecimal } and
Router(config-if)#IP netmask-format { bitcount | decimal |
hexadecimal } are correct. You can configure the mask for the
current session and you can configure it for a specific line.
When
configuring the subnet mask for an IP address, which formats can
be used?
-
A.
dotted-decimal.
