Which password must an engineer use to enter the enable mode?
A.
adminadmin123
B.
default
C.
testing 1234
D.

Explanation: If neither the enable password command nor the enable secret command is
configured, and if there is a line password configured for the console, the console line
password serves as the enable password for all VTY sessions -> The “enable secret” will
be used first if available, then “enable password” and line password.
What is the purpose of using First Hop Redundancy Protocol in a specific subnet?
A.
Filter traffic based on destination IP addressing
B.
Sends the default route to the hosts on a network
C.
ensures a loop-free physical topology
D.
forwards multicast hello messages between routers
forwards multicast hello messages between routers
Explanation: FHRP is layer 3 protocol whose purpose is to protect the default gateway by
offering redundancy of the gateway in a subnet. This is achieved by allowing two or more
routers to provide a backup for the first-hop IP router address. If a failure of an active router
occurs, the backup router will take over the address. The routers negotiate their roles
(Active/Standby) with each other by multicast hello messages to share the VIP (virtual IPaddress) between the FHRP routers. The terms Active/Standby vary between the different
types of FHRP. The active router will act as the default gateway and the standby router
acts as a backup the active router
