191 Identify 2 PPP
characteristics?
A.) Is proprietary to Cisco
B.) Supports authentication
C.) Support compression
D.) Run on a multi-access network
Ans B C
PPP supports authentication; PAP and CHAP. It also supports
compression; Stacker and Predictor.
192 Which statement is true regarding half duplex?
A.) Only works in a point-to-point configuration
B.) Allows for transmitting and receiving but not a the same
time
C.) Allow for transmitting and receiving of data simultaneously
D.) Doubles the bandwidth
Ans B
Half duplex is analogous to a single a lane bridge, it can
handle traffic in both directions but no at the same time.
193 Identify the purpose of the wildcard mask?
A.) Match a certain portion of the IP address while ignoring the
rest of the address
B.) Determine the class of the IP address
C.) Determine the network portion of an IP address
D.) Hide the host portion of an IP address
Ans A
The purpose of the wildcard mask to match a certain portion of
the IP address while ignoring the rest.
194 Identify the OSI layer associated with bits?
A.) Physical
B.) Network
C.) Binary
D.) Data link
Ans A
The Physical layer converts the frames to bits.
195 Identify the type of routing protocol that maintains a
topological database of the network?
A.) Topological state
B.) Shortest Path First
C.) Link state
D.) Distance vector
Ans C
Link State routing protocols maintain a database that lists all
the networks in the internetwork.
196 Identify the 3 major functions at layer 3 of the OSI
model?
A.) Forwarding process
B.) Logical addressing
C.) End-to-end connections
D.) Path selection
E.) MAC address examination
F.) Network monitoring
Ans A B D
Layer 3 determines the path, forwards the packet and implements
software or logical addressing.
197 Identify the 2 rules used when configuring a Distance
Vector routing protocol?
A.) Physically connected network(s)
B.) Configure the classful address, no subnets
C.) Enable CDP so neighbors can be detected
D.) Configure all networks in Area0
Ans A B
When configuring a Distance Vector routing protocol only assign
the physically connected networks with the classful address
only.
198 Identify 3 characteristics of an IP address?
A.) Contains a network portion and a host portion
B.) 32 bits long
C.) Unique to each network
D.) Part of the default Cisco configuration
E.) Referred to as the hardware address
Ans A B C
An IP address is 32 bits long, it is referred as the logical or
software address. It contains a network and host portion. Each
IP address is unique.
199 Identify 3 feature of access-lists?
A.) Implicit deny will deny any packets not matched
B.) Processed sequentially from bottom to top
C.) Processed sequentially from top to bottom
D.) If a packet is denied it would be tested against the
remaining statements in the access-list
E.) Once a match is made the packet is either denied or
permitted
F.) Enabled on all interfaces by default
Ans A C E
Access-list are processed from top to bottom, once a match
occurs the packet is either denied or permitted and is no longer
tested and if no match occurs the packet is denied via the
implicit deny.
200 Which OSI layer performs code conversion, code formatting
and encryption?
A.) Physical
B.) Data-Link
C.) Application
D.) Transport
E.) Presentation
F.) Network
Ans E
Layer 6 the Presentation layers performs this function.
