問題 #45
An LTM device has a virtual server mapped to www.f5.com. Users report that when they connect to /resources
/201.1.2h.l_l.com they are unable to receive content. What is the likely cause of the issue?
答案：D
解題說明：
The Control Plane is responsible for ARP (Address Resolution Protocol) management for Virtual Addresses.
For a Virtual Server to be reachable, the BIG-IP must respond to ARP requests for that IP. If the "ARP" setting is disabled on the Virtual Address properties, upstream routers cannot resolve the MAC address of the BIG-IP, leading to connectivity failure even if the service itself is "Available."
問題 #46
A BIG-IP Administrator is unable to connect to the management interface via HTTPS. What is a possible reason for this issue?
答案：B
解題說明：
Management connectivity is protected by an allowed access list for the httpd daemon. Unlike TMM data ports which use ' Port Lockdown ' settings, the management port ' s access is controlled by a specific ' Allow ' list.
If an administrator ' s IP is not explicitly included in this list, the Control Plane will reject HTTPS connection attempts to the management utility.
問題 #47
One of the two members of a device group has been decommissioned. The BIG-IP Administrator tries to delete the device group, but is unsuccessful. Prior to removing the device group, which action should be performed? (Choose one answer)
答案：B
解題說明：
A BIG-IP device group cannot be deleted if it still contains device members, even if one of those devices has already been decommissioned or is unreachable. Before deleting the device group, the administrator must explicitly remove the decommissioned device from the device group configuration.
Once the removed or unreachable device is deleted from the device group membership, the BIG- IP system allows the remaining administrator to successfully delete the device group.
問題 #48
A BIG-IP Administrator needs to update the list of configured NTP servers. In which area of the Configuration Utility should the BIG-IP Administrator perform this update?
答案：B
解題說明：
NTP (Network Time Protocol) is vital for management connectivity and HA state synchronization.
Correct time is required for log timestamping and device trust group communication. To manage these settings, the administrator navigates to System > Configuration, where general system- level services like NTP and DNS are defined to ensure the Control Plane remains synchronized with the network environment.
問題 #49
Refer to the output.
Color green
Status In Sync
Summary
Details
/Common/host1.company.com: connected (for 2548 seconds)
/Common/sync-fail-test (In Sync):
- all 2 devices consistent
/Common/device_trust_group (In Sync):
- all 2 devices consistent
Which TMSH command generated this output?
答案：B
解題說明：
The correct command is tmsh show /cm sync-status because the displayed output is operational synchronization status, not configuration data. In TMSH, show is used to display runtime or current operational state, while list is used to display saved configuration objects and configured properties. The output contains status fields such as Color , Status , Summary , and Details , showing that the BIG-IP device is In Sync and that both the sync-fail-test device group and device trust group have all devices consistent.
This is live ConfigSync/device-group state information under the configuration management module /cm .
Therefore, the command that generates this status output is tmsh show /cm sync-status . Option A is incorrect because tmsh list /cm sync-status would attempt to list configuration, not display the operational sync status shown in the exhibit.
