Connected network
2. Static route
3. EIGRP
4. OSPF
5. RIP
True or False - A router must know an entire path from beginning to end to successfully route
traffic correct answers false
Distance vector routing protocols base their decisions primarily on ______, whereas Link
state routing protocols base their decisions primarily on ______. correct answers The number
of hops to the destination; The quality of a link
Which of the following addresses is NOT involved in routing traffic to a destination
A. Next hop IP address
B. Next hop MAC address
C. IP address of the device sending the traffic
D. IP address of the device the traffic is intended for correct answers C. Ip address of the
device sending the traffic
Which of the following is NOT a source of routing information? correct answers Networks
discovered by using Automatic IP Addressing (APIPA)
Match each routing protocol with the set of characteristics that most closely defines it correct
answers RIP - Distance vector "limit of 15 hops'
Link state - "Dijkstra's algorithm"
BGP - EGP "controls routers for the Internet"
EIGRP - Proprietary "hybrid routing protocol"
IS-IS - Dijkstra's algorithm "not popular"
Which of the following piece of information is required for a router to route traffic correctly?
correct answers Destination IP address
Which of the following routing protocols is NOT an interior gateway protocol (IGP)? correct
answers BGP
Routers using a distance vector routing protocols typically share ______, whereas routers
using a link state routing protocols share______. correct answers Entire routing tables;
information about their own links
, Why is a statically configured route considered to be more believable than a dynamically
learned route? correct answers it involves using information explicitly specified by an
administrator, which is more reliable than second hand information
Choose the item that represents a commonality between MPLS, Frame Relay, and MPLS
connections correct answers Each of them forms connections between sites utilizing a service
provider network (or WAN cloud)
Match each WAN technology with the characteristic that best matches that technology
correct answers DSL - Asymmetric or symmetric
T1 - Dedicated leased line
Cable Modem - DOCSIS
Frame Relay - Packet Switched
ISDN - Bearer and Data Channels
Which of the following protocols can be used to perform authentication of devices in WANs?
correct answers CHAP & PAP
Why is it that a service provider could be considered the most important WAN component?
correct answers They form the WAN connection and are held responsible for its function
between locations and the technologies available can vary by provider
Choose the best description of the term 'demarc' correct answers The point of demarcation,
whereas responsibility passes from the service provider to the subscriber of the service
Each of the following WAN technologies features packet switching capabilities EXCEPT
correct answers ISDN
Which of the following WAN technologies utilizes fiber optics exclusively? correct answers
SONET
True or False - Frame Relay identifies each virtual circuit by its VCI (Virtual Circuit
Identifier) correct answers False
Which of the following physical mediums are NOT used in WAN connections?
Coaxial cable
Fiber optic
UTP
Satellite correct answers None of the above. Each of the choices is a valid medium for WAN
connections
Digital circuits like T1 or T3 are terminated by a device called a ______ that processes the
incoming signals into bits the router can understand correct answers CSU/DSU
True or False - Cable modem and DSL WAN technologies are both popular in home
networks because they make use of the already existing coaxial media from cable TV
networks correct answers False
True or False - MPLS utilizes its own special use header that is inserted between the native
layer 2 and layer 3 headers of a packet correct answers True
