SIMULATION Task 14 An administrator has seen an abundance of alarms regarding high CPU usage on the NSX Managers. The administrator has successfully cleared these alarms numerous times in the past and is aware of the issue. The administrator feels that the number of alarms being produced for these events is overwhelming the log files. You need to: * Review CPU Sensitivity and Threshold values. Complete the requested task. Notes: Passwords are contained in the user_readme.txt. This task is not dependent on other tasks. This task should take approximately 5 minutes to complete.
Correct Answer:
See the Explanation part of the Complete Solution and step by step instructions Explanation: To review CPU sensitivity and threshold values, you need to follow these steps: Log in to the NSX Manager UI with admin credentials. The default URL is https://<nsx-manager-ip-address>. Navigate to System > Settings > System Settings > CPU and Memory Thresholds. You will see the current values for CPU and memory thresholds for NSX Manager, NSX Controller, and NSX Edge. These values determine the percentage of CPU and memory usage that will trigger an alarm on the NSX Manager UI. You can modify the default threshold values by clicking Edit and entering new values in the text boxes. For example, you can increase the CPU threshold for NSX Manager from 80% to 90% to reduce the number of alarms for high CPU usage. Click Save to apply the changes. You can also view the historical data for CPU and memory usage for each component by clicking View Usage History. You can select a time range and a granularity level to see the usage trends and patterns over time
Question 2
SIMULATION Task 2 You are asked to deploy three Layer 2 overlay-backed segments to support a new 3-tier app and one Layer 2 VLAN-backed segment for support of a legacy application. The logical segments must block Server DHCP requests. Ensure three new overlay-backed segments and one new VLAN-backed logical segment are deployed to the RegionA01-COPMOI compute cluster. All configuration should be done utilizing the NSX UI. You need to: Complete the requested task. Notes: Passwords are contained in the user_readme.txt. Task 2 is dependent on the completion of Task 1. Other tasks are dependent on completion of this task. You may want to move to the next tasks while waiting for configuration changes to be applied. This task should take approximately 10 minutes to complete.
Correct Answer:
See the Explanation part of the Complete Solution and step by step instructions Explanation: To deploy three layer 2 overlay-backed segments and one layer 2 VLAN-backed segment, you need to follow these steps: Log in to the NSX Manager UI with admin credentials. The default URL is https://<nsx-manager-ip-address>. Navigate to Networking > Segments and click Add Segment. Enter a name for the segment, such as Web-01. Select Tier-1 as the connectivity option and choose an existing tier-1 gateway from the drop-down menu or create a new one by clicking New Tier-1 Gateway. Enter the gateway IP address of the subnet in a CIDR format, such as 192.168.10.1/24. Select an overlay transport zone from the drop-down menu, such as Overlay-TZ. Optionally, you can configure advanced settings such as DHCP, Metadata Proxy, MAC Discovery, or QoS for the segment by clicking Set Advanced Configs. Click Save to create the segment. Repeat steps 2 to 8 for the other two overlay-backed segments, such as App-01 and DB-01, with different subnet addresses, such as 192.168.20.1/24 and 192.168.30.1/24. To create a VLAN-backed segment, click Add Segment again and enter a name for the segment, such as Legacy-01. Select Tier-0 as the connectivity option and choose an existing tier-0 gateway from the drop-down menu or create a new one by clicking New Tier-0 Gateway. Enter the gateway IP address of the subnet in a CIDR format, such as 10.10.10.1/24. Select a VLAN transport zone from the drop-down menu, such as VLAN-TZ, and enter the VLAN ID for the segment, such as 100. Optionally, you can configure advanced settings such as DHCP, Metadata Proxy, MAC Discovery, or QoS for the segment by clicking Set Advanced Configs. Click Save to create the segment. To apply a segment security profile to block DHCP requests on the segments, navigate to Networking > Segments > Segment Profiles and click Add Segment Profile. Select Segment Security as the profile type and enter a name and an optional description for the profile. Toggle the Server Block and Server Block - IPv6 buttons to enable DHCP filtering for both IPv4 and IPv6 traffic on the segments that use this profile. Click Save to create the profile. Navigate to Networking > Segments and select the segments that you want to apply the profile to. Click Actions > Apply Profile and select the segment security profile that you created in step 18. Click Apply to apply the profile to the selected segments. You have successfully deployed three layer 2 overlay-backed segments and one layer 2 VLAN-backed segment with DHCP filtering using NSX-T Manager UI.
