NEW QUESTION # 28
Which two items demonstrate the creation of a new volume for software images? (Choose two.)
Answer: A,B
Explanation:
In BIG-IP, software images are installed on boot volumes (for example, HD1.1, HD1.2, HD1.3, etc.).
To install software on a new volume, the administrator must instruct the system to create a new boot location 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
This GUI method is officially supported and explicitly creates a new boot volume before installing the software.
NEW QUESTION # 29
How should the BIG-IP Administrator block connections to a Self IP on port 443 while allowing connections to other ports?
Answer: C
Explanation:
Port Lockdown controls which protocols/ports are allowed to access a Self IP. Using Allow Custom lets the administrator explicitly define a whitelist of permitted ports - so you would add all desired ports except 443, effectively blocking it while allowing everything else needed.
NEW QUESTION # 30
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 before the image appears in the GUI under:
System ยป Software Management ยป Image List?
Answer: C
Explanation:
When a TMOS ISO file is transferred to /shared/images/, the BIG-IP automatically performs a validation step:
Checksum Verification
Before the image becomes visible in the GUI, the system verifies the internal checksum embedded inside the ISO.
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."
NEW QUESTION # 31
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?
Answer: C
Explanation:
The exhibit shows aSelf IPwith:
* 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 blocksallservices 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 byPort Lockdown = Allow None, which prevents SNMP communication.
Why the other options are incorrect:
B). Traffic Group must use a floating Traffic Group
* SNMP polling doesnotrequire floating Self IPs.
* Floating groups apply to HA failover IPs, not SNMP functionality.
C). VLAN/Tunnel must allow All VLANs
* Self IPs are always bound to a VLAN; SNMP doesnotrequire All VLANs.
* As long as the Self IP belongs to a reachable VLAN, SNMP can work.
D). Configuration is correct
* It is not correct:Allow Noneblocks SNMP and is the problem.
NEW QUESTION # 32
The BIG-IP Administrator needs to update access to the Configuration Utility to include the
172.28.31.0/24 and 172.28.65.0/24 networks. From the TMOS Shell (tmsh), which command should the BIG-IP Administrator use to complete this task?
Answer: A
Explanation:
Access to the BIG-IP Configuration Utility (TMUI) is controlled through the /sys httpd allow list.
This list defines which IP addresses or subnets are allowed to connect to the management web interface.
To allow two new subnets--172.28.31.0/24 and 172.28.65.0/24--the administrator must add both subnets to the existing list without removing current entries.
In tmsh, subnet entries must be specified in network/netmask format, for example:
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 }
