質問 # 23
A secondary administrator has been granted access to a BIG-IP device through itsManagement Interface, but is unable to access theConfiguration Utility (WebUI).
What command can be run from the CLI to capture the network traffic on themanagement interfaceand troubleshoot the issue?
(Choose two.)
正解：D、E
解説：
The BIG-IP has two distinct planes:
* Management-plane# handled entirely by the management interface (MGMT)
* Data-plane (TMM)# handles Self IPs, VLAN interfaces, and traffic processing To capture traffic on the management interface, only the management-side NICs may be used:
* mgmt# Logical name for the management interface
* eth0# Physical Linux interface mapped to the management port on most BIG-IP platforms Both of these correctly capture inbound/outbound WebUI (HTTPS/443) traffic on the management port.
Why the correct answers are A and B
A). tcpdump -i eth0 -n port 443
* On BIG-IP appliances and VMs, the management port maps toeth0at the Linux OS level.
* Capturing on eth0 correctly shows HTTPS traffic to the WebUI.
B). tcpdump -i mgmt -n port 443
* mgmtis the BIG-IP alias for the management interface.
* This is thepreferredand most explicit capture interface for management-plane packet captures.
Why the other options are incorrect:
C). tcpdump -i 0.0
* Interface0.0is the TMM switch interface used for data-plane packet captures.
* Itdoes NOTcapture management-plane traffic.
D). tcpdump -i tun0
* Used for tunnel interfaces (IPsec, VXLAN, etc.)
* Not related to management access.
E). tcpdump -i management
* There isnointerface named management on BIG-IP.
* The correct names are mgmt or eth0.
質問 # 24
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?
正解：B
解説：
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.
質問 # 25
Refer to the exhibit.
An organization has purchased a BIG-IP license that includes all available modules but has chosen to provision only the modules they require.
The exhibit displays the current resource allocation from the System -> Resource Provisioning page.
Based on the information provided, which F5 modules have been provisioned?
正解：A
解説：
The exhibit shows the Current Resource Allocation for:
CPU
Disk
Memory
In particular, the Memory Allocation bar displays the modules that are currently provisioned.
Memory is the most reliable indicator because BIG-IP allocates memory only to modules that are actively provisioned.
From the exhibit:
MGMT (Management) - always present
TMM (Traffic Management Microkernel) - indicates LTM is provisioned
GTM - this label indicates that the DNS module is provisioned (GTM = Global Traffic Manager, now called DNS) APM - explicitly shown, indicating Access Policy Manager is provisioned Therefore, the provisioned modules are:
LTM (implied by TMM allocation)
DNS/GTM
APM
This matches Option C: LTM, DNS, APM.
質問 # 26
Which two items demonstrate thecreation of a new volumefor software images?
(Choose two.)
正解：A、D
解説：
In BIG-IP, software images are installed onboot volumes(for example, HD1.1, HD1.2, HD1.3, etc.).
To install software on anew 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-volumekeyword
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.
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 anexistingvolume only
* The GUI install dialog does not create new boot volumes
Thus, onlyOption AandOption Cproperly create a new software volume.
質問 # 27
The Configuration Utility of a BIG-IP device is currently accessible via its management IP10.53.1.245from all VLANs.
The BIG-IP Administrator needs to restrict access so only hosts from the10.0.0.0/24subnet can access the Configuration Utility.
Which TMSH command accomplishes this?
正解：B
解説：
BIG-IP controls access to the web-based Configuration Utility (TMUI) through the/sys httpd allowlist. This parameter specifies which client IPs or subnets may initiate HTTP/HTTPS connections to the management interface.
To restrict TMUI access toonlythe 10.0.0.0/24 subnet:
* The correct method is tomodify the HTTPD allow listso that it contains only this subnet.
* This requires replacing the entire current list with the new subnet using:
modify /sys httpd allow replace-all-with {10.0.0.0/24}
This ensures thatonlyclients within 10.0.0.0/24 can reach the Configuration Utility.
Why the other options are incorrect:
* Options A and Ccreate network ACL objects under /net acl, which apply to data-plane traffic, not management-plane TMUI access. TMUI access is not controlled by LTM ACLs but by the HTTPD allow directive.
* Option Bis incorrect syntax and references /ltm httpd, which is not the proper object; the correct hierarchy is /sys httpd.
Thus, only modifying the/sys httpd allowlist achieves the required restriction.
