OSPF Mastery Quiz
Test your knowledge on OSPF (Open Shortest Path First) protocols with this comprehensive quiz designed for network professionals. Whether you are preparing for a certification or just want to sharpen your skills, this quiz provides a range of questions covering various aspects of OSPF.
- Multiple-choice and checkbox questions.
- Challenging scenarios that require in-depth understanding.
- Perfect for students and network engineers alike.
Which command will a network engineer issue to verify the configured hello and dead timer intervals on a point-to-point WAN link between two routers that are running OSPFv2?
Show ipv6 ospf interface serial 0/0/0
Show ip ospf neighbor
Show ip ospf interface fastethernet 0/1
Show ip ospf interface serial 0/0/0
An administrator is configuring single-area OSPF on a router. One of the networks that must be advertised is 64.102.0.0 255.255.255.128. What wildcard mask would the administrator use in the OSPF network statement?
0.0.31.255
0.0.0.63
0.0.63.255
0.0.0.127
Refer to the exhibit. Suppose that routers B, C, and D have a default priority, and router A has a priority 0. Which conclusion can be drawn from the DR/BDR election process?
If the priority of router C is changed to 255, then it will become the DR.
Router A will become the DR and router D will become the BDR.
If the DR fails, the new DR will be router B.
If a new router with a higher priority is added to this network, it will become the DR.
What indicates to a link-state router that a neighbor is unreachable?
If the router no longer receives hello packets
If the router receives an update with a hop count of 16
If the router receives an LSP with previously learned information
If the router no longer receives routing updates
Which three OSPF states are involved when two routers are forming an adjacency? (Choose three.)
Exchange
Init
ExStart
Two-way
Loading
Down
What is a benefit of multiarea OSPF routing?
Topology changes in one area do not cause SPF recalculations in other areas.
Routers in all areas share the same link-state database and have a complete picture of the entire network.
A backbone area is not required.
Automatic route summarization occurs by default between areas.
Which task has to be performed on Router 1 for it to establish an OSPF adjacency with Router 2?
Issue the clear ip ospf process command.
Change the subnet mask of interface FastEthernet 0/0 to 255.255.255.0.
Remove the passive interface command from interface FastEthernet 0/0.
Add the network 10.0.1.0 0.0.0.255 area 0 command to the OSPF process.
What is the reason for a network engineer to alter the default reference bandwidth parameter when configuring OSPF?
To force that specific link to be used in the destination route
To more accurately reflect the cost of links greater than 100 Mb/s
To enable the link for OSPF routing
To increase the speed of the link
In an OSPFv2 configuration, what is the effect of entering the command network 192.168.1.1 0.0.0.0 area 0?
It allows all 192.168.1.0 networks to be advertised.
It tells the router which interface to turn on for the OSPF routing process.
It changes the router ID of the router to 192.168.1.1.
It enables OSPF on all interfaces on the router.
After modifying the router ID on an OSPF router, what is the preferred method to make the new router ID effective?
HQ# copy running-config startup-config
HQ# resume
HQ# clear ip route *
HQ# clear ip ospf process
What is the format of the router ID on an OSPF-enabled router?
A unique router host name that is configured on the router
A unique phrase with no more than 16 characters
A 32-bit number formatted like an IPv4 address
An 8-bit number with a decimal value between 0 and 255
A character string with no space
An administrator is configuring single-area OSPF on a router. One of the networks that must be advertised is 192.168.223.0 255.255.254.0. What wildcard mask would the administrator use in the OSPF network statement?
0.0.1.255
0.0.7.255
0.0.15.255
0.0.31.255
Which step in the link-state routing process is described by a router running an algorithm to determine the best path to each destination?
Load balancing equal-cost paths
Declaring a neighbor to be inaccessible
Choosing the best route
Executing the SPF algorithm
