Question 1

You have just changed the community string within the snmpd. conf on a Linux server. What needs to occur to monitor this device in Orion?

Accepted Answer

The SNMP process on the Linux server needs to be restarted to apply the changes made to the snmpd.conf file, including the updated community string, so that Orion can monitor the device with the new settings.

Question 2

Companies A and B have merged and are both using the 10.10.x..x /16 networks. Company A uses Orion NPM and would like to monitor two key servers within company B'snetwork. Which solution for this situation involves the fewest configuration steps?

Accepted Answer

Using static NAT allows specific IP addresses from Company B's network to be mapped to unique IP addresses that Company A can access, requiring fewer configuration steps than re-addressing the entire network or setting up dynamic NAT.

Question 3

What does the command "ip ssh version 2"do on a Cisco IOS router?

Accepted Answer

The command "ip ssh version 2" on a Cisco IOS router is used to enable Secure Shell (SSH) version 2, which is a protocol for secure remote login and other secure network services over an insecure network.

Question 4

Your firewall currently allows port 6343 traffic to your network management system (NMS). What is the port most likely being used for?

Accepted Answer

Port 6343 is commonly used for sFlow, which is a network monitoring protocol.

Question 5

When using a network management system (NMS) to monitor network interfaces on a router, you notice that statistics are wrong after an interface card is physically removed from the device. What has most likely caused this problem?

Accepted Answer

When an interface card is removed, the remaining interfaces may be re-indexed, causing the NMS to associate statistics with the wrong interfaces.

Question 6

Which two sources provide detailed visibility into router interface traffic? (Choose two.)

Accepted Answer

SNMP statistics and NetFlow provide detailed visibility into router interface traffic. SNMP statistics provide information about the number of packets, bytes, and errors on an interface, while NetFlow provides information about the source and destination of traffic, as well as the type of traffic.

Question 7

Company A and company B have merged and are currently planning to combine their network backbones. All 18 of company A's routers run OSPF, but company B's hardware only supports RIPv2. You need to monitor both networks from a single NMS. Which solution in volves the fewest configuration steps to meet these monitoring requirements?

Accepted Answer

Router redistribution allows different routing protocols to communicate with each other, enabling monitoring from a single NMS with minimal configuration changes.

Question 8

What can you determine from a packet capture that you CANNOT learn from NetFlow data?

Accepted Answer

A packet capture can reveal information that is not available in NetFlow data, such as the router Telnet password.

Question 9

Your network management system (NMS) leverages WMI to pull management data from Windows 2003 Servers. You have not deployed Active Directory, but your servers belong to a common workgroup. What should you do to ensure that your NMS has permission to query these servers?

Accepted Answer

The answer of Your network management system (NMS) leverages WMI...

Question 10

Your service level agreement (SLA) dictates that you must be able to notify the appropriate parties when systems are down for over2 minutes and report on data for the last120 days. Your network management system (NMS) has been configured to collect status every 10minutes and summarizes and retains data for 90 days. Which two settings should you change in the NMS to meet the business requirements? (Choose two.)

Accepted Answer

The answer of Your service level agreement (SLA) dictates that...

Question 11

You are planning a network management implementation where the network has several low bandwidth WAN links. Which two network management protocols are most likely to cause heavy traffic on WANs and should therefore be considered carefully before deployment? (Choose two.)

Accepted Answer

The answer of You are planning a network management implementation...

Question 12

A network engineer is planning to deploy a network management system (NMS) to monitor a network. Which two UDP ports should be enabled in router access control lists and firewalls so the NMS can effectively monitor devices? (Choose two.)

Accepted Answer

The answer of A network engineer is planning to deploy...

Question 13

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

Accepted Answer

SNMP (Simple Network Management Protocol) uses UDP traffic on port 161 for sending requests from the manager to the agent.

Question 14

What is a concern when monitoring a layer 3 (hierarchical) network that is not a concern when monitoring a layer 2 (flat) network?

Accepted Answer

In a layer 3 network, access control lists (ACLs) can block management traffic, which is not a concern in a layer 2 network where ACLs are not typically used for traffic filtering.

Question 15

Which advantage do SNMP traps and Syslog have over SNMP polling?

Accepted Answer

SNMP traps and Syslog provide faster event detection because they push notifications immediately when an event occurs, unlike SNMP polling which periodically checks for events.

Question 16

The IP address of a network management system (NMS) is 10.1.5.2, and the IP address of a new server that it is monitoring on the same VLAN is 10.1.5.129. The NMS cannot reach the server with SNMP or ICMP. What is the most likely cause?

Accepted Answer

The most likely cause is that the subnet mask of the server is misconfigured, causing it to be on a different subnet than the NMS, even though they are intended to be on the same VLAN.

Question 17

While attempting to add a device to Orion for monitoring, you find that Orion can communicate with the device for latency measurements, but is not able to pull data such as CPU load or interface traffic. What should you verify first?

Accepted Answer

Verify that you have the correct SNMP community string for the device, as this is necessary for Orion to pull data like CPU load or interface traffic from the device.

Question 18

Which two management protocols should you use to measure the effectiveness of your QoS implementation? (Choose two.)

Accepted Answer

SNMP (Simple Network Management Protocol) and NetFlow are both used for monitoring and measuring network performance, including QoS (Quality of Service) metrics. SNMP provides network management data, while NetFlow provides detailed traffic flow information.

Question 19

The IT budgeting department has asked you for reports that will help them better plan for increases in monthly recurring costs. Which report should you set up to help the IT udgeting department meet this objective?

Accepted Answer

WAN interface utilization reports can help the IT budgeting department understand current usage patterns and anticipate future increases in monthly recurring costs related to bandwidth and connectivity.

Question 20

Users are complaining that a network connection is slow. How should SNMP be used to verify performance of the interface?

Accepted Answer

The ifInOctets SNMP object can be used to monitor the amount of incoming traffic on an interface, which helps in assessing bandwidth usage and identifying potential network congestion issues.
