NEW QUESTION # 16
What command will allow the BIG-IP Administrator to view theconfigured management IPof a BIG-IP system?
(Choose one.)
Answer: C
Explanation:
Comprehensive and Detailed Explanation (Paraphrased)
The BIG-IP stores the configured management IP address as asystem configuration objectunder the/sys hierarchy.
To display configured (persistent) values, BIG-IP uses thetmsh list command, not show.
Why tmsh list sys management-ip is correct
* The management IP configuration is defined under:
* /sys management-ip
* Running:
* tmsh list sys management-ip
displays:
* The configured management IP address
* Netmask
* Associated attributes
This command shows theactual configured management IP, which is what the question asks for.
Why the other options are incorrect
A). tmsh show sys management-ip
* The show command is used for runtime statistics and status.
* management-ip is a configuration object, not a statistics object.
C). tmsh list sys management-route
* Displays management routing information, not the management IP address itself.
D). tmsh list net self
* Displays Self IPs used on the data plane.
* Does not show the management interface IP.
NEW QUESTION # 17
Refer to the exhibit. What traffic will be permitted to reach the BIG-IP?
Answer: A
Explanation:
The exhibit shows the configuration of a Self IP with:
Port Lockdown: Allow Custom
A Custom List that includes the following TCP ports:
443
22
Meaning of these ports:
TCP 443 -> HTTPS (TMUI -- web-based management)
TCP 22 -> SSH (command-line remote access)
No other TCP, UDP, or protocol entries are listed; therefore, only these two services are allowed to reach the BIG-IP via this Self IP.
Evaluating the answer choices:
Option Service Port Allowed?
Not allowed
FTP TCP 21 Not listed
Allowed
SSH TCP 22 Listed
Not allowed
Telnet TCP 23 Not listed
Thus, SSH is the only traffic permitted through this Self IP configuration.
NEW QUESTION # 18
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.)
Answer: D,E
Explanation:
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.
NEW QUESTION # 19
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?
Answer: B
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 only supported location from which the BIG-IP software installation system validates and installs 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
/shared/images/ so that:
The GUI (System Software Management Available Images) can detect the image TMSH install software image commands can reference it Other directories such as /local/images/ or /var/images/ are not valid storage paths for software images.
NEW QUESTION # 20
Refer to the exhibit.
