OSPF
To verify which OSPF neighbors a Cisco router has formed adjacencies with and check their states, what command should be used?
show ip ospf neighbor
OSPF is classified as what type of dynamic routing protocol?
Link State routing protocol
Protocols that carry traffic between separate autonomous systems belong to what routing protocol category?
Exterior Gateway Protocols
RIPv2 is classified as what type of dynamic routing protocol?
Distance Vector routing protocol
What three dynamic routing protocols are the main ones used in the Fleet Marine Force (FMF)?
OSPF, RIPv2, and BGP
To compute the best loop-free route to each destination, link-state protocols such as OSPF rely on what algorithm?
Dijkstra Shortest Path First algorithm
In a multi-area OSPF design, what is Area 0 called?
The backbone area
BGP is classified as what kind of routing protocol?
Path-vector protocol
What metric does RIP use to determine the best path to a destination?
Hop count
What term describes a collection of routers and network devices under the administrative control of a single organization?
An autonomous system
On networks with many devices, at which point in the OSPF adjacency process are the DR and BDR chosen?
During the 2-Way state
In OSPF, all non-backbone areas must connect to what area?
Area 0, the backbone area
In the BGP best path selection algorithm on Cisco routers, what attribute is evaluated first?
Highest Weight
What feature does RIPv2 support that RIPv1 does not, because RIPv2 includes subnet mask information in its updates?
Variable Length Subnet Masking (VLSM)
Among all route sources, which type of route is preferred above all others because its administrative distance is 0?
Connected routes
When two OSPF routers have completely matched their Link-State Databases, what adjacency state have they reached?
Full State
What is the role of an Area Border Router (ABR) in OSPF?
It summarizes and shares routes between OSPF areas
What dynamic routing protocol is used in modern networks to connect different Autonomous Systems?
BGP
What is the maximum usable hop count in RIPv2 before a network is considered unreachable?
15
What is the main benefit of distance vector routing protocols over link state routing protocols?
They have low CPU and memory use, allowing them to run on older hardware
What OSPF router type connects the OSPF network to outside networks, such as the Internet or a BGP network?
Autonomous System Boundary Router
What kind of router is re-elected if the Designated Router (DR) fails?
Backup Designated Router (BDR)
What command can be used to display all BGP neighbor adjacenies?
sh ip bgp all summ
What type of authentication does RIPv2 support to ensure routing updates come from trusted routers?
MD5 authentication
What are the three main components of a dynamic routing protocol?
Data structures, routing messages, and algorithms
