Term
WHICH STATEMENT MOST ACCURATELY DESCRIBES STATIC AND DYNAMIC ROUTES?
Definition
STATIC ROUTES ARE MANUALLY CONFIGURED BY A NETWORK ADMINISTRATOR, WHEREAS DYNAMIC ROUTES ARE AUTOMATICALLY LEARNED AND ADJUSTED BY ROUTING PROTOCOL.
Term
WHICH OF THE FOLLOWING PROTOCOLS IS AN EXAMPLE OF AN EXTERIOR GATEWAY PROTOCOL?
Definition
BGP
Term
IN WHICH SITUATION IS AN ADMINISTRATIVE DISTANCE REQUIRED?
Definition
WHEN THE SAME ROUTE IS LEARNED VIA MULTIPLE ROUTING SOURCES
Term
HOW DOES A DISTANCE VECTOR ROUTER LEARN ABOUT PATHS FOR NETWORK THAT ARE NOT DIRECTLY CONNECTED?
Definition
FROM NEIGHBORING ROUTERS
Term
WHAT DOES A DISTANCE VECTOR ROUTER SEND TO NEIGHBORING ROUTERS AS PART OF A PERIODIC ROUTING-TABLE UPDATE?
Definition
THE ENTIRE ROUTING TABLE
Term
WITH DISTANCE VECTOR ROUTING, COUNT TO INFINITY CAN BE PREVENTED BY SETTING A MAXIMUM FOR WHAT VALUE?
Definition
METRIC
Term
WHAT DOES SPLIT HORIZON SPECIFY?
Definition
THAT INFORMATION ABOUT A ROUTE SHOULD NOT BE SENT BACK IN THE DIRECTION FROM WHICH THE ORIGINAL INFORMATION CAME.
Term
WHEN A ROUTER SETS THE METRIC FOR A DOWN NETWORK TO THE MAXIMUM VALUE, WHAT IS IT DOING?
Definition
POISONING THE ROUTE
Term
IF A ROUTE FOR A NETWORK IS IN HOLDDOWN AND AN UPDATE ARRIVES FROM A NEIGHBORING ROUTER WITH A POORER METRIC THAN WAS ORIGINALLY RECORDED FOR THE NETWORK, WHAT DOES THE ROUTER DO?
Definition
IGNORE THE UPDATE
Term
IF A ROUTER HAS A NETWORK PATH IN HOLDDOWN AND AN UPDATE ARRIVES FROM A NEIGHBORING ROUTER WITH A BETTER METRIC THAN ORIGINALLY RECORDED FOR THE NETWORK, WHAT TWO THINGS DOES IT DO?
Definition

REMOVES THE HOLDDOWN

 

AND 

 

MARKS THE ROUTE AS "ACCESSIBLE"

Term
HOW CAN LINK-STATE PROTOCOLS LIMIT THE SCOPE OF ROUTE CHANGES?
Definition
BY SEGMENTING THE NETWORK INTO AREA HIERARCHIES.
Term
WHAT IS THE PURPOSE OF LINK-STATE ADVERTISEMENTS (LSA)?
Definition
TO CONSTRUCT A TOPOLOGICAL DATABASE
Term
WHAT ARE TWO CHARACTERISTICS OF OSPF?  (NEED TO KNOW ALL!)
Definition
HIERARCHICAL AND OPEN STANDARD
Term
OSPF ROUTES PACKETS WITHIN A SINGLE ______________.
Definition
autonomous system
Term
HOW MANY SUBNETS ARE GAINED BY SUBNETTING 172.17.32.0/20 IN MULTIPLES OF /28 SUBNETS?
Definition
256
Term
HOW MANY HOSTS CAN BE ADDRESSED ON A SUBNET THAT HAS SEVEN HOST BITS?
Definition
126
Term
HOW MANY HOST CAN BE ADDRESSED WITH A PREFIX OF /30?
Definition
2
Term
WHICH SUBNET MASK WOULD BE APPROPRIATE FOR A CLASS C ADDRESS USED FOR 9 LANs, EACH WITH 12 HOSTS?
Definition
255.255.255.240
Term
HOW CAN YOU MOST EFFECTIVELY SUMMARIZE THE IP RANGE OF ADDRESSES FROM 10.1.32.0 TO 10.1.35.255?
Definition
10.1.32.0/22
Term
WHICH OF THE FOLLOWING COMMANDS MAKES RIPv2 AND EIGRP IMPLEMENT CLASSLESS BEHAVIOR?
Definition
no auto-summary
Term
HOW CAN YOU MOST EFFECTIVELY SUMMARIZE THE IP RANGE OF ADDRESSS FROM 172.168.12.0/24 TO 172.168.13.0/24?
Definition
172.168.12.0/23
Term
T/F: A DISTANCE VECTOR ROUTING ALGORITHM SENDS ITS ENTIRE ROUTING TABLE TO ITS NEIGHBORS.  LINK-STATE ROUTING ALGORITHMS MAINTAIN A COMPLEX DATABASE OF TOPOLOGY INFORMATION, WHICH ROUTERS USE TO MAINTAIN FULL AWARENESS OF DISTANT ROUTERS.
Definition
TRUE
Term
WHAT IS OSPF?
Definition
IT IS A CLASSLESS, LINK-STATE ROUTING PROTOCOL THAT IS WIDLEY DEPLOYED IN MANY NETWORKS.  EIGRP IS A CLASSLESS ROUTING PROTOCOL THAT BEHAVES LIKE A CLASSFUL ROUTING PROTOCOL BY DEFAULT.
Term
WHAT IS VLSM (VARIABLE LENGTH SUBNET MASK)?
Definition
ALLOW MULTILPLE LEVELS OF SUBNETWORKED IP ADDRESSES WITHIN A SINGLE NETWORK AND PROVIDE EFFICIENT ALLOCATION OF IP ADDRESSES.
