Routing

Correct Answer: Implement administrative distance configuration

The best option for the administrator in this scenario is to 'Implement administrative distance configuration'. Administrative distance is a metric used by routers to select the best path when there are two or more different routes to the same destination from two different routing protocols. Administrative distance defines the reliability of a routing protocol. In this case, the administrator needs to configure the administrative distances of EIGRP and OSPF in such a way that would avoid routing loops. Let's look at the other options - 'Change EIGRP to RIPv2': Changing EIGRP to RIPv2 doesn't necessarily solve the problem of a routing loop. It would just replace one dynamic routing protocol with another and the loop can persist if there is no administrative management for these two protocols'Increase OSPF hello timers': The OSPF hello timers are the mechanism OSPF uses to establish neighbor relationships. While increasing these timers would increase the interval at which routers send hello packets, it does not directly address the issue of a routing loop'Disable the EIGRP routing protocol': This option might solve the issue temporarily, but it isn't very efficient. Disabling an entire routing protocol can lead to network outages and loss of connectivity in areas relying on that protocol. Therefore, the best solution here is to manage the interoperability of the protocols.

Correct Answer: Add the same destination with different metrics for multiple paths

The scenario indicates that network traffic is not being distributed across different routes, even when the main route is congested. This suggests that the metrics for the multiple static routes need adjusting. Metrics are used to determine the 'cost' of a route, lower cost meaning more preference. Therefore, to fix the issue, the network administrator should 'Add the same destination with different metrics for multiple paths'. This will allow the network to make dynamic decisions about which route to use based on the different cost of each route. Answer 'Remove all static routes' is not beneficial because it doesn't provide an alternative routing solution and might cause network unavailability. Changing 'the subnet masks', answer, isn't a relevant solution to the problem, as this would only affect IP address ranges within the network, not the routing behaviour. Lastly, adding 'the same destination with the same metrics for multiple paths' is unlikely to resolve the issue, because this could lead to routing loops or continued congestion on a preferred route.

Correct Answer: DNS server misconfiguration

The issue the network is experiencing is DNS server misconfiguration. DNS (Domain Name System) is responsible for translating domain names to IP addresses. If users can't access websites using domain names but can with IP addresses, it indicates a problem with the DNS server, not properly translating those domain names into IP addresses. The other answers are incorrect because: A DHCP server misconfiguration would result in issues obtaining an IP address for the network, not translating domain names. A routing loop could cause network congestion but would not particularly affect the translation of domain names to IP addresses. A missing static route would fail to direct traffic to a specific network or host, but it would not influence the translation of a domain name into an IP address.
