Network+ Chapter 10 Flashcards
is used to rate the trustworthiness of routing information received on one router from its neighboring router. pg 300
administrative distance (AD)
Disabling all the routing protocols except this _______protocol improved the network at least 30% pg 301
EGIRP (this would only work on an all-Cisco router network)
What is the default administrative distance of static route?
ch 10 pg 301
1
What is the default administrative distance of Internal EIGRP? ch 10 pg 302
90
What is the default administrative distance of RIP?
ch 10 pg 302
120
What is the default administrative distance of External EIGRP?
ch 10 pg 302
170
Using link state protocols, also called what?
ch 10 pg 302
shortest path first protocols,
This protocol uses aspects of both distance vector and link state, and formerly, EIGRP was the only one you needed to understand to meet the Network + objectives.Ch 10 pg 303
hybrid protocol
If a router finds more than one link with the same hop count to the same remote network, it will automatically perform what’s known as what? Ch 10 pg 303
round-robin load balancing.
What are 4 differences between RIPv1 and RIPv2.
Ch 10 og 306
RIPv1 Classful Broadcast Based No Support for VLSM No Authentication
RIPv2 Classless Uses multicast 224.0.0.9 Supports VLSM Allows for MDS Authentication
By using a VLSM design, your network will run faster and you can save a lot of IP addresses. Ch 10 pg 308
False-By using a VLSM design, you do not necessarily make your network run better, but you can save a lot of IP addresses.
What is a discontigous network?
Its a network that has two or more subnetwork of classful network connected together by different classful networks
What are 3 reasons to create a OSPF in a Hierarchical design?
To decrease routing overhead
To Speed Up Convergence
To confine network instability to single areas of the network.
is a path whose reported distance is less than the feasible (best) distance, and it is considered a backup
route. pg 311
Feasible Successor (Backup Routes)
is an open-standard routing protocol that’s been implemented by a wide variety of network vendors, including Cisco. pg 313
Open Shortest Path First (OSPF)
which algorithm is used by OSPF? pg 314
Dijkstra algorithm.
is a link state routing protocol, meaning it operates by reliably flooding topology information throughout a network of routers.
(p. 316).
IS-IS
is a reference to the default router being the first router, or _________ through which a packet must pass.
(p. 317).
first hop
This also provides a redundant— but again, not load-balanced— gateway for hosts on a local subnet.
(p. 319).
Virtual Router Redundancy Protocol (VRRP).
The_______ timer is the defined interval during which each of the routers send out ______ messages.
(p. 322).
Hello Timer
allows a group of routers to form a single virtual router.
