161 What is the purpose of
ARP?
A.) IP to host name resolution
B.) Host name to IP address resolution
C.) Mac to IP address resolution
D.) IP to Mac address resolution
Ans D
Address Resolution Protocol resolves the MAC address if the IP
address is known. It is a layer 3 protocol.
162 Which OSI layer establishes, maintains and terminates
sessions between hosts?
A.) Application
B.) Physical
C.) Data-Link
D.) Presentation
E.) Network
F.) Session
Ans F
Layer 5 the Session layer performs this function.
163 Which statement is true regarding Administrative
distance?
A.) It is a metric
B.) Number of hops between two routers
C.) Trustworthiness of the routing information
D.) RIP Administrative distance is 100
Ans C
Administrative distance is rating of trustworthiness of the
routing information. The lower the AD the better the
information.
164 Identify the purpose of the Ping command?
A.) Share routing information with a neighbor router
B.) Transmit user data when buffers are full
C.) Test connectivity at layer 3
D.) Test entire protocol stack
Ans C
The ping command tests layer 3 connectivity.
165 Identify the order of the 5 step encapsulation?
1. Create the segment
2. Convert the frame to bits
3. Create the packet
4. Create the frame
5. User creates the data
A.) 1,2,4,2,5
B.) 2,1,3,4,5
C.) 5,1,3,4,2
D.) 5,3,4,1,2
Ans C
Cisco 5 step encapsulation.
1) User creates Data
2) Data is converted into a segment at layer 4
3) The segment is converted to packet at layer 3
4) The packet it converted into a frame at layer 2
5) The frame is converted into bits at layer 1
166 The Cisco IOS is stored where?
A.) ROM
B.) CD
C.) Flash
D.) NVRAM
Ans C
By default the Cisco IOS is stored in flash.
167 Sequence and acknowledgement numbers are used for?
A.) Layer transitioning
B.) Flow control
C.) Port number addressing
D.) Reliability
Ans D
TCP uses sequence numbers and acknowledgements to implement
reliability.
168 Identify IPX GNS and it's purpose?
A.) Go Network Server - sends a print job to a network server
B.) Get Nearest Server - locate the nearest server
C.) Guaranteed Network Services - allocates resources to users
D.) Get Notes Server - locates Domino Server
Ans B
GNS stands for Get Nearest Server, initiated by a workstation.
169 Identify the true statement regarding subnetting?
A.) Allows for more host address
B.) Borrow bits from the network portion of the address
C.) Allows for unlimited number of networks
D.) Borrow bits from the host portion of the address
Ans D
Subnetting involves borrowing bits for the host portion of the
address to be used to subnet addressing.
170 Inverse ARP serves what purpose?
A.) Method for a local router to introduce itself to the remote
end of the connection
B.) Broadcast a routing table update
C.) Identify MAC addresses if the IP address is known
D.) Sent every 10 seconds used to verify the Frame Switch is
still active
Ans A
Inverse ARP operates in a Frame Relay network so the two end
points can identify themselves to each other.
