最新的 F5-CA F5CAB1 免費考試真題 (Q54-Q59):

問題 #54
How can the BIG-IP Administrator tell when anunlicensed modulehas been provisioned?

A. AProvisioning Warningwill be displayed in the GUI in the upper left corner.
B. A BIG-IP does not allow unlicensed modules to be provisioned.
C. When provisioning an unlicensed module, a warning will appear.

答案：A

解題說明：
The BIG-IP system has built-in licensing enforcement.
If an administrator provisions a module that the device isnot licensedto run, the system will still allow the provisioning action to occurinitially, but the system detects the mismatch and displays an alert.
What actually happens:
* The GUI places awarning bannerin theupper-left cornerlabeled something similar to:"Provisioning Warning"
* This appears immediately after provisioning a module that is not included in the active license.
* The system remains in an "inconsistent state" until the module is disabled again or the license is updated.
This is the visual cue BIG-IP uses to indicate that a module was provisioned without valid licensing.
Why the other options are incorrect:
A). "A BIG-IP does not allow unlicensed modules to be provisioned."
* Not true. BIG-IPdoesallow provisioning, but warns afterward.
B). "A warning will appear when provisioning an unlicensed module."
* The warning doesnotappear during the provisioning step itself.
* It appearsafter provisioning, in the main GUI, as a system banner.

問題 #55
The BIG-IP Administrator uses Secure Copy Protocol (SCP) to upload a TMOS image to the
/shared/images/ directory in preparation for a TMOS upgrade.
After the upload is completed, what will the system do before the image is shown in the GUI under:
System » Software Management » Image List?

A. The system copies the image to /var/local/images/
B. The system performs a reboot into a new partition
C. The system verifies the internal checksum

答案：C

解題說明：
When a TMOS image (.iso file) is uploaded into the /shared/images/ directory, the BIG-IP performs an internal validation step before the ISO appears in the GUI.
1. The system verifies the internal checksum
BIG-IP automatically reads the embedded checksum inside the ISO file
Verifies integrity of the uploaded image
Confirms the file is not corrupted or incomplete
Ensures the image is a valid F5 TMOS software image
Only after this checksum verification succeeds does the image appear under:
System -> Software Management -> Image List

問題 #56
The device is currently on v15.1.2.1.
The BIG-IP Administrator needs to boot the device back to v13.1.0.6 to gather data for troubleshooting.
The system shows:
Sys::Software Status
Volume Product Version Build Active Status Allowed
HD1.1 BIG-IP 15.1.2.1 0.0.10 yes complete yes
HD1.2 BIG-IP 13.1.0.6 0.0.3 no complete yes
Which is the correct command-line sequence to boot the device to version 13.1.0.6?

A. switchboot -b HD1.2, then reboot
B. Use tmsh to select a new boot volume, tmsh reboot HD1.2
C. Use tmsh to select a new boot volume, tmsh switchboot HD1.2
D. switchboot -I HD1.2, then reboot

答案：A

解題說明：
To change the boot volume on a BIG-IP system from one installed TMOS version to another, the correct CLI tool is:
switchboot
The correct syntax uses the -b flag:
switchboot -b <volume>
This command marks the specified boot location as the one to be used on the next reboot.
Thus, to boot into HD1.2 which contains 13.1.0.6, the sequence is:
Mark HD1.2 as the next boot location:
switchboot -b HD1.2
Reboot the system:
reboot
This is the standard and officially supported method for selecting a different installed volume.

問題 #57
The monitoring team reports that the SNMP server is unable to poll data from a BIG-IP device.

What information will help the BIG-IP Administrator determine whether the issue originates from the BIG-IP system?

A. The "VLAN / Tunnel" setting must allow All Vlans.
B. The "Traffic Group" setting must use a floating Traffic Group.
C. The configuration on the exhibit is correct and other options should be explored.
D. The "Port Lockdown" setting is preventing the SNMP server from polling data from the BIG-IP.

答案：D

解題說明：
The exhibit shows a Self IP with:
VLAN: Data
Port Lockdown: Allow None
Impact of "Allow None" on SNMP
When a Self IP is configured with:
Port Lockdown: Allow None
the BIG-IP blocks all services and ports except a few hardcoded HA communication ports.
This means:
UDP/161 (SNMP) is blocked
UDP/162 (SNMP traps) is blocked
The SNMP server cannot poll or receive data from the BIG-IP through this Self IP SNMP relies on access through the Self IP if out-of-band (mgmt interface) is not used.
Thus, the issue is directly caused by Port Lockdown = Allow None, which prevents SNMP communication.

問題 #58
Which configuration file can a BIG-IP administrator use to verify theprovisioned modules?

A. /var/local/ucs/config.ucs
B. /config/bigip.license
C. /config/bigip.conf
D. /config/bigip_base.conf

答案：C

解題說明：
Provisioning settings define which modules are enabled and how system resources are allocated to them.
These provisioning declarations are stored in:
/config/bigip.conf
This file contains:
* Full module provisioning statements
* TMSH-equivalent provisioning configurations such as:
* sys provision ltm { level nominal }
* sys provision asm { level nominal }
It is theprimary system configuration filethat stores all active provisioning details.
Why the other answers are incorrect
A). /config/bigip.license
* Showslicensedmodules, not provisioned modules.
B). /config/bigip_base.conf
* Stores base networking (VLANs, Self-IPs, routes), not provisioning.
D). config.ucs
* A backup archive, not a live configuration file.
Thus, the correct file to review active module provisioning is/config/bigip.conf.
