Question 1

Which traffic type should be allowed through the network in order to leverage HTTPS for network monitoring?

Accepted Answer

HTTPS traffic typically uses TCP on port 443, so allowing TCP traffic on port 443 is necessary for monitoring HTTPS traffic.

Question 2

Which two metrics should be monitored to determine if a network device is overloaded? (Choose two.)

Accepted Answer

The answer of Which two metrics should be monitored to...

Question 3

A network engineer would recommend decreasing polling frequency in order to address which topology-based issue?

Accepted Answer

The answer of A network engineer would recommend decreasing polling...

Question 4

Without regard to reliability, what is the fastest method for detecting network faults?

Accepted Answer

Listening for SNMP traps is the fastest method because it involves receiving asynchronous notifications from devices, which immediately alert to network faults without the need for polling or querying.

Question 5

You are monitoring a Windows 2003 Server via SNMP. Which service must be enabled on the target server to allow the network management service (NMS) to collect CPU load data?

Accepted Answer

The SNMP Service must be enabled on the target server to allow the NMS to collect CPU load data via SNMP.

Question 6

Users at a remote site in Paris are complaining that access to the company CRM is slow. Orion is collecting data on this performance, but you need a more real-time perspective on the problem. What should you do?

Accepted Answer

Launching a real-time tool will provide immediate insights into the performance issue as it occurs, allowing for quicker diagnosis and resolution.

Question 7

Which trend analysis report would most accurately predict user count growth?

Accepted Answer

The number of active switch ports is a good indicator of user count growth because it shows how many devices are connected to the network. As the number of users grows, the number of active switch ports will also grow.

Question 8

Orion NPM is showing that a router in a remote site is down. However, Orion indicates that other devices at that site are up. What is the most likely cause?

Accepted Answer

If ICMP replies are disabled on the router, Orion NPM would not receive ping responses, leading it to report the router as down, while other devices could still be up and responding.

Question 9

Wireless users are complaining of sporadic network access issues. After reviewing the data collected by Orion, it seems that there is one specific wireless user that is causing the issue and that every WAP that they connect to is adversely affected. What should you do to resolve this issue?

Accepted Answer

Blocking the user's MAC address will prevent them from connecting to any WAPs, thereby resolving the issue they are causing across the network.

Question 10

You are using a protocol analyzer to capture a packet trace in order to troubleshoot a specific network problem. Which change must you make on the Ethernet switch in order to facilitate the packet capture?

Accepted Answer

To capture packets for analysis, you need to mirror or span the traffic from the target port to the port where your analyzer is connected. This allows the analyzer to receive and capture the traffic for troubleshooting.

Question 11

Refer to the following configuration snippet of a Cisco IOS router: snmp-server community private RO 60 snmp-server host 192.168.15.4 private access-list 60deny 192.168.12.0 255.255.240.0 access-list 60 permit snmp 192.168.15.4 The network management system (NMS) IP address is 192.168.15.4, and it is receiving SNMP traps from the router, but it is not able to poll the router. Why is the NMS unable to poll the router?

Accepted Answer

The access-list 60 is denying SNMP access from the NMS because the deny statement for the 192.168.12.0 network is too broad and overlaps with the NMS IP address, preventing it from polling the router.

Question 12

Over the course of 24 hours, a node was sent 200 ping requests in an effort to monitor its availability. Of those 200 ping requests there were: 100 responses of less than 10ms 50 responses of greater than 20ms 50 requests with no responses What was the availability of that node during this period of time?

Accepted Answer

Availability = (Number of successful requests / Total number of requests) * 100= (100 + 50) / 200 * 100= 150 / 200 * 100= 75%

Question 13

Why are management loopback interfaces important when managing routers, switches, and firewalls?

Accepted Answer

Loopback interfaces are virtual interfaces that are always up as long as the device is operational, providing a stable IP address for management and monitoring purposes.

Question 14

What is the most reliable method of detecting network issues?

Accepted Answer

SNMP polling is the most reliable method of detecting network issues because it actively queries devices for information, rather than relying on devices to send traps or messages.

Question 15

Which port status is caused by users disconnecting their machines from an Ethernet switch?

Accepted Answer

When users disconnect their machines from an Ethernet switch, the port status typically changes to "down" because there is no active connection.

Question 16

Users of a remote site are complaining that network performance is intermittently slow. You review the current status of their network with Orion NPM and do not see any issues. What should you do next?

Accepted Answer

The answer of Users of a remote site are complaining...

Question 17

A firewall separates Orion NPM and the network devices it is monitoring. Only encrypted communication will be allowed from the server for polling and configuration management. Which two ports will need to be allowed through the firewall? (Choose two.)

Accepted Answer

The answer of A firewall separates Orion NPM and the...

Question 18

While monitoring your network with Orion NPM, you notice that several of the devices in your remote offices periodically go into a "warning" state, but then quickly go back into an "up" state. While the devices are in "warning" state, the users at those sites report normal operations. What is the most likely cause of this occurrence?

Accepted Answer

During network congestion, ICMP packets may be dropped, causing temporary "warning" states in Orion NPM, even though users experience normal operations.

Question 19

What is the maximum allowable downtime for a node with a"four nines" (99.99%) service level agreement (SLA) for availability, based on a 30-day month?

Accepted Answer

A "four nines" (99.99%) SLA allows for 0.01% downtime, which is approximately 4.32 minutes in a 30-day month.

Question 20

Which network management system (NMS) statistic is most likely to indicate a potential network growth issue?

Accepted Answer

High bandwidth utilization can indicate that the network is nearing its capacity, suggesting a need for growth or upgrades to handle increased traffic.
