To allow two new subnets— and —the administrator must both subnets to the 172.28.31.0/24 172.28.65.0/24 add existing list without removing current entries. In tmsh, subnet entries must be specified in , for example: network/netmask format 172.28.31.0/255.255.255.0 The correct tmsh command to append these networks is: modify /sys httpd allow add { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 } Why the other options are incorrect: Option B: IPs are listed without masks, which is invalid for subnet-based access control. The system requires format. network/netmask Option C: F5 - F5CAB1 Certs Exam 2 of 10 Pass with Valid Exam Questions Pool A. B. C. The command uses permit instead of allow, which is not a valid attribute of /sys httpd. The correct keyword must be allow Thus, only correctly adds both permitted subnets in the proper tmsh format. Option A Question #:2 - [Identify management connectivity configurations] The BIG-IP Administrator received a ticket that an authorized user is attempting to connect to the Configuration Utility from a jump host and is being denied. The HTTPD allow list is configured as: sys httpd { allow { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 } } The jump host IP is 172.28.32.22 What command should the BIG-IP Administrator use to allow HTTPD access for this jump host? modify /sys httpd allow replace-all-with { 172.28.32.22 } modify /sys httpd allow delete { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 } modify /sys httpd allow add { 172.28.32.22 } Answer: C Explanation The HTTPD allow list controls which IP addresses or subnets may access the Configuration Utility (TMUI) on the BIG-IP system. The Administrator already has two subnets allowed and needs to add a to single host IP the existing list. The object supports actions such as , , and /sys httpd allow add delete replace-all-with Because the goal is to one more entry without removing the existing permitted subnets, the correct add command is: modify /sys httpd allow add { 172.28.32.22 } This appends the new host to the existing list while preserving the previously configured networks. Why the other options are incorrect: Option A (replace-all-with) would the entire allow list, removing existing permitted subnets— overwrite unacceptable. F5 - F5CAB1 Certs Exam 3 of 10 Pass with Valid Exam Questions Pool A. B. C. Option B (delete) would the existing networks and not add the required host. remove Therefore, the correct administrative action is to the jump host’s IP. add Question #:3 - [Apply procedural concepts required to manage software images] 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 the image is shown in the GUI under: before System » Software Management » Image List ? The system performs a reboot into a new partition The system verifies the internal checksum The system copies the image to /var/local/images/ Answer: B Explanation When a TMOS image (.iso file) is uploaded into the directory, the BIG-IP performs an /shared/images/ 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 Why the other options are incorrect: A. The system performs a reboot into a new partition Uploading an ISO file never triggers a reboot. C. The system copies the image to /var/local/images/ F5 - F5CAB1 Certs Exam 4 of 10 Pass with Valid Exam Questions Pool A. B. C. All valid TMOS images remain in /shared/images/ No copying occurs. Question #:4 - [Apply procedural concepts required to manage software images] A BIG-IP Administrator is using Secure Copy Protocol (SCP) to transfer a TMOS image to the BIG-IP system in preparation for an upgrade. To what directory should the file be transferred? /shared/images/ /local/images/ /var/images/ Answer: A Explanation BIG-IP systems require all ISO images (base TMOS images and HotFix images) to be stored in a specific directory used for software installation: /shared/images/ This directory: Is the from which the BIG-IP software installation system validates and installs only supported location ISO files Is accessible by both the GUI and TMSH installers Has adequate storage space allocated specifically for images Is part of the shared partition that persists across reboots When transferring images via SCP, the administrator must copy them directly into so that: /shared/images/ The GUI (System # Software Management # Available Images) can detect the image TMSH install software image commands can reference it Other directories such as or are not valid storage paths for software images. /local/images/ /var/images/ Question #:5 - [Apply procedural concepts required to manage software images] Which two items demonstrate the for software images? creation of a new volume F5 - F5CAB1 Certs Exam 5 of 10 Pass with Valid Exam Questions Pool A. B. C. D. E. (Choose two.) tmsh install software image /shared/images/BIGIP-<version>.iso volume HD1.5 create-volume tmsh install /sys software image BIGIP-<version>.iso volume HD1.5 create-volume Using the GUI, go to , select . In the pop-up window, type the System > Disk Management New Volume name or number of the new volume and click Apply tmsh install sys software image /shared/images/BIGIP-<version>.iso volume HD1.5 create-volume Using the GUI, go to , and in the Install System > Software Management > Available Images > Install Software Image pop-up window, type the new volume name or number and click Install Answer: A C Explanation In BIG-IP, software images are installed on (for example, HD1.1, HD1.2, HD1.3, etc.). boot volumes To install software on a , the administrator must instruct the system to create a new boot location new volume before installation. There are two correct ways to create a new volume: A. tmsh command (with correct syntax) tmsh install software image /shared/images/BIGIP-<version>.iso volume HD1.5 create-volume This syntax correctly includes: install software image full path to ISO (/shared/images/...) volume name (HD1.5) create-volume keyword This instructs BIG-IP to create the new boot volume as part of the installation. C. Using the GUI # System > Disk Management From the Disk Management menu, the administrator can: Select “New Volume” Enter the volume identifier (e.g., HD1.5) Apply changes F5 - F5CAB1 Certs Exam 6 of 10 Pass with Valid Exam Questions Pool A. B. C. This GUI method is officially supported and explicitly creates a new boot volume before installing the software. Why the other options are incorrect: B. Incorrect tmsh syntax Missing /shared/images/ path Incorrect command structure D. Incorrect command structure Missing required keywords and correct command hierarchy E. Software Management # Install does NOT create volumes This installs to an volume only existing The GUI install dialog does not create new boot volumes Thus, only and properly create a new software volume. Option A Option C Question #:6 - [Apply procedural concepts required to manage software images] The BIG-IP Administrator uses Secure Copy Protocol (SCP) to upload a TMOS image to the /shared/images/ directory in preparation for an upgrade. After the upload is complete, what will the system do the image appears in the GUI under: before System » Software Management » Image List ? The system performs a reboot into the new partition The system verifies the internal checksum The system copies the image to /var/local/images/ Answer: B Explanation When a TMOS ISO file is transferred to , the BIG-IP automatically performs a validation step: /shared/images/ Checksum Verification Before the image becomes visible in the GUI, the system embedded verifies the internal checksum inside the ISO. F5 - F5CAB1 Certs Exam 7 of 10 Pass with Valid Exam Questions Pool A. B. C. D. This ensures: The file was fully transferred The image is not corrupted It matches the official F5 release signature Only after passing this verification does the GUI display the ISO under “Available Images.” Why the other options are incorrect: A. Reboot into a new partition No reboot occurs simply from uploading an image. C. Copying into /var/local/images/ This directory is used for ISO storage. not All valid images remain in /shared/images/ Thus, the correct system action is checksum verification Question #:7 - [Identify management connectivity configurations] A BIG-IP Administrator needs to verify the state of equipment in the data center. A BIG-IP appliance has a on the status LED. solid yellow indicator How should the administrator interpret this LED indicator? Appliance is halted or in End-User Diagnostic (EUD) mode Appliance is a standby member in a device group A warning-level alarm condition is present A power supply is NOT operating properly Answer: C Explanation BIG-IP hardware platforms use chassis LEDs to indicate system health states. A typically indicates a , such as: solid yellow status LED warning condition A non-critical hardware alert F5 - F5CAB1 Certs Exam 8 of 10 Pass with Valid Exam Questions Pool A. B. C. A temperature threshold nearing limit A minor fan or sensor irregularity Other non-fatal environmental or system conditions This state reflects a , meaning the unit is operational but requires investigation. warning-level alarm Why the other options are incorrect A. Halted or EUD mode This is associated with different LED patterns (usually flashing conditions or specific color codes), not a solid yellow status LED. B. Standby in device group HA state is not indicated by the chassis status LED. Standby status is a device state, not a hardware LED state. logical D. Power supply failure Power supply indicators use separate LEDs located on each power module (usually flashing amber/red), not the system status LED. Thus, a signifies a solid yellow status indicator warning-level alarm Question #:8 - [Apply procedural concepts required to manage software images] Which command will display the on a BIG-IP system? current active volume tmsh show sys version tmsh show sys software status tmsh list sys software update Answer: B Explanation To identify which boot volume is currently active on a BIG-IP system, the correct command is: tmsh show sys software status This command displays: All installed boot volumes (HD1.1, HD1.2, HD1.3, etc.) F5 - F5CAB1 Certs Exam 9 of 10 Pass with Valid Exam Questions Pool A. B. C. The BIG-IP software version installed on each volume The field, indicating which volume the system is currently booted from Active The installation status (“complete”, “in-progress”, “allowed”) This is the way to determine the active boot location. standard and authoritative Why the other options are incorrect: A. tmsh show sys version Displays OS version, build, and date. Does show boot locations or which volume is active. not C. tmsh list sys software update Shows software update configurations, not boot volume status. Does not display which volume is active. Question #:9 - [Explain the processes of licensing, license reactivation, and license modification] When is the enforced on a BIG-IP system? License Service Check Date After editing a virtual server During a software install During system startup Answer: B Explanation The determines whether a particular software version is allowed to run under the device’s Service Check Date license. When installing or upgrading TMOS, the installer checks the stored in the BIG-IP Service Check Date license file. If the license date is than the minimum required for the target version, the software installation is older blocked This check happens , not during routine device operations. specifically during a software install Editing virtual servers or system startup do not trigger this validation. F5 - F5CAB1 Certs Exam 10 of 10 Pass with Valid Exam Questions Pool A. B. C. Thus, the enforcement happens during software installation Question #:10 - [Explain the processes of licensing, license reactivation, and license modification] For an upgrade of a standalone BIG-IP, a maintenance window is available in which brief interruptions are allowed. Actions with no impact can be done outside the maintenance window. When should a license reactivation be performed? During the maintenance window. Before the maintenance window. After the maintenance window. Answer: B Explanation License reactivation updates the BIG-IP device’s license file to ensure: The is current Service Check Date The device is eligible to install the intended TMOS version Any module entitlement updates are received Reactivation and does not require a reboot, making it safe to perform the does not interrupt traffic before maintenance window. F5 best practices state: Perform to the scheduled maintenance window all non-impact tasks prior Leave the window available for activities that require rebooting, such as the software installation itself Since license reactivation is , it should be done the upgrade window starts. non-disruptive before About certsout.com certsout.com was founded in 2007.
