Question 1

Which protocol should a network engineer enable on routers and switches to collect utilization statistics?

Accepted Answer

SNMP (Simple Network Management Protocol) is used to collect and organize information about managed devices on IP networks and can be used to monitor network utilization statistics.

Question 2

The IT planning department has asked for a report to help them understand when they need to implement IPv6. Which report would offer them the greatest amount of relevant information?

Accepted Answer

IP address utilization trends would provide insights into how close the organization is to exhausting its available IPv4 addresses, indicating when IPv6 implementation might be necessary.

Question 3

How can you use a network management system (NMS) to ensure service level agreement (SLA) parameters are realistic for your environment?

Accepted Answer

Baselining network performance helps in understanding the current capabilities and limitations of the network, which is essential for setting realistic SLA parameters.

Question 4

Which two variables are used in the calculation of Percent Utilization? (Choose two.)

Accepted Answer

Percent Utilization is calculated using configured bandwidth and bits per second.

Question 5

A network engineer is enabling SNMP on their network devices and needs to ensure it will use message integrity. Which version of SNMP should they use?

Accepted Answer

SNMPv3 provides message integrity through the use of authentication and encryption.

Question 6

A network engineer is planning to deploy a network management system (NMS) to monitor a large campus network. What is the most secure way to isolate the NMS network traffic to all monitored routers and switches?

Accepted Answer

Creating a management VLAN for the NMS isolates the management traffic from the rest of the network, enhancing security by ensuring that only devices within the VLAN can communicate with the NMS.

Question 7

Which two reporting requirements should you consider when specifying data roll-up settings for a network management system (NMS)? (Choose two.)

Accepted Answer

Data granularity and data retention are crucial for specifying data roll-up settings in an NMS. Granularity determines the level of detail in the data, while retention specifies how long the data should be stored.

Question 8

What should you do to track whether a new configuration has alleviated slow network performance?

Accepted Answer

Comparing application responsiveness before and after the change directly measures the impact of the new configuration on network performance from the user's perspective.

Question 9

Orion NPM is using SNMP to poll a routerand track interface traffic rates. The data are Collected every 5 minutes, and the most recent values collected for a specific interface are 1,000,000 and 2,000,000 octets. What is the approximate average rate of traffic for this interface?

Accepted Answer

The average rate of traffic is (1,000,000 + 2,000,000) / 2 / 5 * 8 = 240,000 bits per second, which is approximately 26 Kbps.

Question 10

Orion NPM is monitoring the performance of DS-3 utilizing standard MIBs in the ifTable. Occasionally, the reported traffic rates for this interface spike well above45 Mbps. What is the most likely cause?

Accepted Answer

Counter rollovers are likely causing the reported traffic rates to spike above 45 Mbps, as DS-3 interfaces have a maximum capacity of 45 Mbps, and older MIB counters can roll over, leading to incorrect readings.

Question 11

You have recently implemented a VoIP infrastructure within the company network. You are receiving trouble tickets indicating calls are dropping between their New York and San Francisco offices. Which two IP service level agreement (SLA) measurements should you use to identify the cause of the issue?

Accepted Answer

Latency and jitter are critical measurements for VoIP quality. High latency can cause delays, and jitter can cause packets to arrive out of order, both leading to call drops.

Question 12

You are monitoring your Internet connection, and your ISP has guaranteed512 Kbps. Historical data shows that your connection speed holds at 256 Kbps for long periods of time, but never exceeds this speed. What does this indicate?

Accepted Answer

This indicates that the ISP has likely misconfigured the link, as the connection speed never exceeds 256 Kbps, which is half of the guaranteed 512 Kbps.

Question 13

Which two performance metrics can be affected by proper QoS implementation? (Choose two.)

Accepted Answer

Jitter and latency are two performance metrics that can be affected by proper QoS implementation. Jitter is the variation in the delay of packets, and latency is the time it takes for a packet to travel from one point to another. QoS can be used to prioritize certain types of traffic, such as voice or video, and to ensure that these packets are delivered with low jitter and latency.

Question 14

The data center team requires that they be alerted if any of the servers in a remote site go down. However, they do NOT want to receive alerts when the remote site connection goes down. Which two configuration steps should you take within your network management system (NMS) to meet these requirements? (Choose two.)

Accepted Answer

Alerts on server status and remote connection status as dependencies for each of the servers will meet the requirements.

Question 15

What is an advantage of using SNMPv2c over using SNMPv1?

Accepted Answer

The answer of What is an advantage of using SNMPv2c...

Question 16

Which management protocol should you use to analyze network traffic in and out of a router interface?

Accepted Answer

sFlow is a protocol specifically designed for monitoring network traffic, providing detailed information about data flows through network devices like routers.

Question 17

How does the Orion Universal Device Poller (UnDP) monitor a device's statistics that are Not included in the standard Orion NPM MIB database?

Accepted Answer

The Orion Universal Device Poller (UnDP) allows users to manually associate a device's OID (Object Identifier) to Orion, enabling the monitoring of statistics not included in the standard Orion NPM MIB database.

Question 18

IT management wants to know how they can lower their total power consumption by consolidating equipment and shutting off unnecessary equipment. Which type of report can you create to help them plan for this?

Accepted Answer

The answer of IT management wants to know how they...

Question 19

Due to a server crash, you had to move Orion to a new server with a new IP address. Which two changes should you make to ensure that Orion functions properly from the new server and IP address? (Choose two.)

Accepted Answer

The access control lists (ACLs) that restrict management protocols and the destination IP address for Syslog and SNMP traps on managed devices need to be updated to reflect the new IP address of the Orion server.

Question 20

When monitoring a remote router with a network management system (NMS), which interface provides the most reliable connectivity?

Accepted Answer

The loopback interface on the router provides the most reliable connectivity because it is a virtual interface that remains up as long as the router is operational, independent of physical interfaces.
