Question 1

Your network management system (NMS) reports memory consumption on a server to be 95%. You connect to the server and see a memory consumption of 80%. What is a possible cause for this inconsistency?

Accepted Answer

The NMS might be displaying an average memory consumption over a period, while the server shows the current real-time memory usage, leading to the discrepancy.

Question 2

The network management system (NMS) has detected that a router has an interface going up and down unexpectedly. You do not have permissions to log in to the router. Which data, gathered by the NMS, should you review to help determine the cause?

Accepted Answer

Syslog messages can provide detailed logs about the events and errors occurring on the router, which can help identify the cause of the interface flapping.

Question 3

Users at a remote site report that Internet access is slower than usual. What should you check to investigate the cause of this issue?

Accepted Answer

Bandwidth reports should be checked to investigate slow Internet access, as they can reveal if the network is congested or if there is insufficient bandwidth available.

Question 4

Austin and New York offices are connected through an MPLS cloud. You receive a trouble ticket stating that a video conference room in the Austin office cannot connect to the video conference room in the New York office. You verify the following information: Trace routes from Austin to New York can make it to the last hop, which is your NYC router. The Austin conference subnet can reach other subnets within the New York office. What is a possible root cause for the lack of connectivity between conference stations?

Accepted Answer

The New York video conference device missing a default route could prevent it from responding to traffic from Austin, even if the Austin subnet can reach other subnets in New York.

Question 5

Home office users (telecommuters) are complaining that they can no longer access the Corporate intranet site. What should you review to investigate this issue?

Accepted Answer

Reviewing recent configuration changes to access control lists (ACLs) and VPN profiles is crucial because these settings directly affect remote access to the corporate intranet. Changes here could block or restrict access for telecommuters.

Question 6

While troubleshooting issues on your network, you notice that route paths frequently change. Which change to your OSPF configuration would capture this issue in Syslog?

Accepted Answer

The "log-adjacency-changes" command in OSPF configuration logs changes in OSPF neighbor adjacencies, which can help identify frequent route path changes.

Question 7

After making a configuration change to a gateway router, all of the devices past that router appear down in the network management system (NMS). However, the NMS is still gathering CPU and memory statistics on the devices. What is the first thing you should do to diagnose the issue?

Accepted Answer

The issue likely stems from a configuration change on the gateway router, such as an access list that might be blocking ICMP traffic, which is used by the NMS to determine device availability.

Question 8

Your company outsources CRM to a SaaS company. Users are complaining that the CRM is down. You verify that Internet connectivity is good and that other Internet sites can be accessed. You contact the CRM provider and find that none of their other customers are having issues. You attempt to ping this IP address from your network management system (NMS), but the ping fails. After reviewing recent changes to your outside router's configuration, you find that several access control lists (ACLs) have been updated. What should you do to verify that the problem is related to the ACL updates?

Accepted Answer

Telnetting to the outside router and pinging the CRM from the router's outside interface will help determine if the ACLs on the router are blocking the traffic. If the ping is successful from the router, it indicates that the ACLs might be the issue.
