Which two situations are the result of excessive broadcast traffic? (Choose two)
a. slow network operations
b. show device operations
c. when devices on all adjacent networks are affected
what is
a. slow network operations
b. show device operations
Slow network operations and slow device operations are the result of excessive broadcast traffic.
Host-A has the IPv4 address and subnet mask 192.168.1.50 255.255.255.0. Which of the following IPv4 addresses would be on the same network as Host-A? (Choose all that apply)
a. 192.168.0.1
b. 192.168.1.1
c. 192.168.1.100
d. 192.168.0.100
what is
b. 192.168.1.1
c. 192.168.1.100
Host A is on network 192.168.1.0. Therefore, devices with the IPv4 addresses 192.168.1.1 and 192.168.1.100 are on the same network.
host range: 192.168.1.1 - 192.168.1.254
True or False:
Multicast transmission reduces traffic by allowing a host to send a single packet to a selected set of hosts that subscribe to a multicast group.
what is true
Multicast transmission reduces traffic by allowing a host to send a single packet to a selected set of hosts that subscribe to a multicast group.
Which command is used to encrypt all passwords in a router configuration file?
a. Router_A(config)# encryption
b. Router_A(config)# service password-encryption
c. Router_A(config)# enable password password encrypted password<password>
what is
b. Router_A(config)# service password-encryption
B. The service password-encryption
command encrypts all passwords in the
running-config and startup-config files. By
default, this is not strong encryption, but
it can be enough to keep someone from
learning passwords

a. Private IPv4 addresses are assigned to devices within an organizations intranet (internal network)
b. internet routers will typically forward any packet with a destination address that is private IPv4 address.
c. Any organization (home, school, office, company) can use the 10.0.0.0/8
what is
a and c
Private IPv4 addresses are assigned to devices within an organization’s intranet (internal network) and any organization (home, school, office, company) can use the 10.0.0.0/8 address.
An administrator is configuring a new router to permit out-of-band management
access. Which set of commands will allow the required login using the password
cisco?
a. Router(config)# line vty 0 4
Router(config-line) password cisco
Router(config-line) login
b. Router(config)# line console 0

b. The console port is used to access the
router using out-of-band management. Both
the password and login commands are
required.
