問題 #43
By default, how often are VRRP-E hello messages sent from the master?

A. every 60 seconds
B. every 5 seconds
C. every 1 second
D. every 3 seconds

答案：C

解題說明：
In Virtual Router Redundancy Protocol Extended (VRRP-E) configurations on RUCKUS ICX switches, the master router sends hello messages at regular intervals to indicate its active status. By default, these hello messages are sent every 1 second.
Key Points:
* Hello Interval: The frequency at which the master router sends hello messages to backup routers.
* Default Value: 1 second.
* Purpose: To inform backup routers of the master's presence and operational status. If backup routers do not receive hello messages within a specified dead interval, they assume the master is down and initiate a failover.
Configuration:
* Viewing Current Settings:
* To display the current VRRP-E configuration, including hello intervals:
sql
Copy code
show vrrp
* Modifying the Hello Interval:
* To change the hello interval, enter VRRP-E configuration mode for the specific virtual router instance and use the following command:
php
Copy code
vrrp <vrid> advertisement-interval <seconds>
* <vrid>: Virtual Router ID.
* <seconds>: Desired interval in seconds.
Example:
To set the hello interval to 2 seconds for VRID 1:
bash
Copy code
enable
configure terminal
interface ethernet 1/1/1
vrrp 1
advertisement-interval 2
exit
write memory
Considerations:
* Network Stability: Setting the hello interval too low can lead to unnecessary failovers due to transient network issues. Conversely, setting it too high can delay failover detection.
* Consistency: Ensure that all routers in the VRRP-E group have consistent hello and dead interval settings to prevent configuration mismatches.

問題 #44
When a high CPU alert about an ICX switch is triggered, which command will provide more detail on the processes taking up CPU cycles?

A. show cpu histogram
B. show process
C. show cpu
D. show cpu tasks

答案：D

解題說明：
When a high CPU utilization alert is triggered on a RUCKUS ICX switch, it's essential to identify the processes consuming excessive CPU resources. The show cpu tasks command provides detailed information about active processes and their CPU usage.
Command Usage:
show cpu tasks
Output Example:
Task Name CPU Time (ms) Invocations Avg Time (us)
------------------ -------------- ------------ -------------
TaskA 5000 1000 5000
TaskB 3000 1500 2000
In this output:
* Task Name lists the names of active processes.
* CPU Time (ms) indicates the total CPU time consumed by each process in milliseconds.
* Invocations shows how many times each process has been called.
* Avg Time (us) represents the average time per invocation in microseconds.
By analyzing this data, administrators can pinpoint processes that are utilizing disproportionate CPU resources, facilitating targeted troubleshooting and optimization.
