201 Identify the 3 methods
routers learn paths to destinations?
A.) Dynamic routing
B.) None of the above, configured by default
C.) Default routes
D.) Administrative distance
E.) Static routes
Ans A C E
Routers can learn paths via 3 different sources; static routes,
dynamic routing protocols (i.e. RIP) and default routes.
202 Identify the purpose of the following command 'ip route
192.168.100.0 255.255.255.0 10.1.0.1'
A.) Enabling a dynamic routing protocol
B.) Creating a static route to the 10.1.0.0 network
C.) Teaches the router about the distant network 192.168.100.0
and how it can be reached via 10.1.0.1
D.) Assigning the IP address 192.168.100.0 to an interface
Ans C
A static routes teaches the router about a distant network and
the next hop to reach that network. Command syntax:
ip route network-address subnet-mask next-hop-address
203 Based upon the 1st octet rule identify the range for a
Class A address?
A.) 1 - 126
B.) 192 - 223
C.) 128 - 191
D.) 1 - 191
Ans A
Class A address has the 1st octet between 1 - 126. Class B
between 128 - 191 and Class C between 192 - 223.
204 What does a Standard IP Access-list use as test criteria?
A.) IP source address
B.) IP source and destination address, protocol numbers and port
numbers
C.) IPX source and destination address
D.) Source MAC address
Ans A
Standard IP access list use only source address.
205 What is the function of the Transport layer and which
protocols reside there?
A.) MAC addressing - IP
B.) Interhost communication - SQL, NFS
C.) Best effort Packet delivery - TCP, UDP
D.) End-to-end connections - TCP, UDP
Ans D
Layer 4, the Transport layer, is responsible for end-to-end
connections. The two TCP/IP protocols that reside there are TCP
and UDP.
206 Identify the 3 Internet layer IP protocols?
A.) NetBios
B.) IPX
C.) ARP
D.) IP
E.) RARP
Ans C D E
NetBios and IPX are not layer 3 IP protocols. IP - Internet
Protocol, ARP - Address Resolution Protocol and RARP - Reverse
Address Resolution Protocol.
207 IPX routing updates occur how often?
A.) Every 30 seconds
B.) Every 60 seconds
C.) Only as needed
D.) When the remote router asks for an update
Ans B
IPX RIP updates are exchanged every 60 seconds.
208 Identify 3 methods not used to prevent routing loops?
A.) Holddown timers
B.) Sequence numbers
C.) Triggered updates
D.) Split horizon
E.) Area hierarchies
F.) Order of router startup
Ans B E F
Area hierarchies, sequence numbers and order of router startup
all relate to Link State routing protocols which do NOT incur
routing loops.
209 Identify the hardware component that stores the bootstrap
program?
A.) ROM
B.) NVRAM
C.) Booter load
D.) RAM
E.) Flash
Ans A
ROM contains the boot strap code.
210 Which OSI layer provides mechanical, electrical,
procedural for activating, maintaining physical link?
A.) Presentation
B.) Network
C.) Application
D.) Physical
E.) Transport
F.) Data-Link
Ans D
Layer 1 the Physical layer performs this function.
