Details of Cisco 300-420 Exam
The Cisco 300-420 exam consists of about 65 questions that have to be answered within the allocated time of 90 minutes. These items can be presented in different formats, including drag and drop, fill-in-the-blank, testlets, and multiple choice. The students are required to achieve the passing score of 750 points out of a total of 1000. This result allows them to get the associated certification. Besides that, the individuals should be ready to pay the fee of $300. After that, they can register and schedule 300-420 ENSLD through Pearson VUE. This platform provides the candidates with two delivery methods. You can choose the in-person variant and sit for the exam at one of the testing centers. On the other hand, you can opt for the online testing and take the exam from the comfort of your home. Those learners who do not complete the test will have a five-day waiting period before their next attempt.

NEW QUESTION 42
A company has the following network infrastructure. (Refer to the exhibit.)
Router A is a GLBP active virtual gateway with priority level set to 250. Routers B and C are configured with the default GLPB configurations. The configuration of the active virtual gateway needs to be changed such that if the AVG fails, Router C should be elected to be used as an active virtual gateway. As the network administrator, you have been asked to make corresponding changes to the configuration.
Which command would you use for this purpose on Router C, and where would the command be configured?
- A. glbp 10 priority 200 (on Router B)
- B. glbp 10 preempt (on Router B)
- C. glbp 10 preempt (on Router C)
- D. glbp 10 priority 200 (on Router C)
Answer: D
Explanation:
You would configure the glbp 10 priority 200 command on Router C to change the configuration as required.
Gateway Load Balancing Protocol (GLBP) gateway priority determines the role that each GLBP gateway plays and what happens if the AVG fails. In the given scenario, Router A is used as an active virtual gateway. If the AVG in a LAN topology fails, an election process takes place to determine which backup virtual gateway should take over. When you configure this command on Router C, Router C will be elected when Router A fails as an AVG.
Once the configuration change is made, it can be verified by examining the output if the show run command as shown below:
In the above output, it can be determined that the glpb priority 200 command has been applied to the gigabitEthernet0/0 interface on Router
C. If the default priority of 100 had been applied, there would be no line in the output for priority. Because Router B is configured with the default configuration, it will have its priority set to the default level as 100.
You would not use the glbp 10 preempt command on Router B or the glbp 10 preempt command on Router C to change the configuration. You would use this command on a router to enable preemption. Preemption allows a virtual router that was once the AVG to assume its role as active virtual router when it comes back online if it has a higher priority than the current AVG. Alternatively, it can enable a new router with a higher priority to take the role of AVG from the current AVG if the new router has a higher AVG.
You would use not the glbp 10 priority 200 command on Router B to change the configuration. You would run this command if you needed Router B to be elected as the AVR instead of Router C, as running this command on Router B would configure it with higher priority than Router C.
