F5 BIG-IP Administration Install, Initial Configuration, and Upgrade Sample Questions (Q15-Q20):NEW QUESTION # 15
Given thatBIGIP-<version>.isoandHotfix-BIGIP-<version>-ENG.isohave been uploaded to/shared/images on an F5 device, what is the appropriatetmshcommand to prepare and update the BIG-IP device with the hotfixof a software version on anew volume HD1.2?
(Choose one.)
  • A. tmsh create /sys software hotfix Hotfix-BIGIP-<version>-ENG.iso volume HD1.2
  • B. tmsh install /sys software hotfix Hotfix-BIGIP-<version>-ENG.iso create-volume HD1.2
  • C. tmsh copy /sys software hotfix Hotfix-BIGIP-<version>-ENG.iso volume HD1.2
  • D. tmsh install /sys software BIGIP-<version>.iso hotfix Hotfix-BIGIP-<version>-ENG.iso create-volume HD1.2
Answer: D
Explanation:
When installing a BIG-IP software versionwith a HotFixon anew boot volume, F5 requires that both thebase TMOS imageand theHotFix imagebe installed together as part of the same installation workflow.
The correct process is:
* Specify thebase TMOS ISO
* Specify theHotFix ISOthat corresponds to that base version
* Instruct the system tocreate a new boot volume
* Install both images into that new volume
This is achieved with the following tmsh syntax:
tmsh install /sys software BIGIP-<version>.iso hotfix Hotfix-BIGIP-<version>-ENG.iso create-volume HD1.2 This command:
* Installs the base image first
* Applies the HotFix on top of the base image
* Creates and installs everything onHD1.2
* Leaves the currently active volume untouched for rollback
Why the other options are incorrect
A). Installing only the hotfix
A HotFix cannot be installed by itself on a new volume. A base image must already be present.
C). Using create instead of install
The create keyword is not valid for software installation operations.
D). Using copy
The copy command does not install software images or hotfixes.

NEW QUESTION # 16
An administrator is in the process of reactivating the license using the interface displayed in the exhibit.

What is the address of the license server to which the BIG-IP device must be able to establish an outbound connection in order to use theAutomatic Activation Method?
  • A. activate.f5.com
  • B. ask.f5.com
  • C. callhome.f5.com
  • D. license.f5.com
Answer: A
Explanation:
When you chooseAutomaticas the activation method in the License , Re-activate screen, the BIG-IP device itself contacts F5'slicense activation serviceover the Internet.
For successful automatic activation:
* The BIG-IP must have outbound network connectivity (typically via the management interface).
* DNS resolution and routing must allow it to reach theF5 license activation host(the one shown in option D).
* The device sends its dossier and registration key to that service and receives an updated license file in return, which is then installed automatically.
The other hostnames in the options are not used by BIG-IP for license activation, so they cannot be correct in the context ofAutomatic Activation.

NEW QUESTION # 17
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.)
  • A. tcpdump -i tun0 -n port 443
  • B. tcpdump -i eth0 -n port 443
  • C. tcpdump -i mgmt -n port 443
  • D. tcpdump -i management -n port 443
  • E. tcpdump -i 0.0 -n port 443
Answer: B,C
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 # 18
A new logging solution is being implemented on the network. Policy requires keeping management traffic sent from the BIG-IPout of the management interface. After configuring the BIG-IP to forward messages to the new Syslog server, the BIG-IP Administrator notices that packets are being sentfrom a numbered data- plane Self IP.
What should the BIG-IP Administrator change to send the traffic out of thecorrect interface?
  • A. Create a new Self IP in the same subnet as the management IP address using a route domain.
  • B. Create a Management Route for the specific address/subnet of the syslog service via TMSH.
  • C. Modify the port lockdown settings on the Self IP address to allow UDP port 514 traffic.
  • D. Set the Management IP as the source address when configuring a Remote Syslog destination.
Answer: B
Explanation:
By default,management-plane trafficuses themanagement routing table, whiledata-plane trafficuses the TMM routing table.
Remote Syslog traffic ismanagement-planetrafficunlessa management route exists.
If noManagement Routematches the Syslog server's destination IP, the BIG-IP will instead:
* UseTMM routes, and
* Source the packets from aSelf IP
This is exactly what the administrator is observing.
To force Syslog traffic out the management port:
You must create aManagement Route, which is configured using:
tmsh create /sys management-route <name> gateway <ip> network <syslog subnet> This sends syslog traffic:
* Out of themanagement interface
* Using theManagement IPas the source
Thus,Option Bis correct.
Why the other options are incorrect:
A). Set the Management IP as the source address
* Source address selection is overridden by routing.
* Without a management route, traffic still goes out the data plane.
C). Create a new Self IP using a route domain
* Unnecessary and not related to management-plane routing.
* Syslog traffic should not rely on data-plane Self IPs.
D). Modify port lockdown on Self IP to allow UDP/514
* This would allow Syslog trafficintothe BIG-IP over a Self IP, not forceoutboundtraffic via management.

NEW QUESTION # 19
The Port Lockdown feature prevents unwanted connection attempts to a Self IP.
Which three types of connection attempts areunaffectedby Port Lockdown settings?
  • A. Defined virtual server traffic, Internet Control Message Protocol (ICMP), Centralized Management Infrastructure (CMI)
  • B. Centralized Management Infrastructure (CMI), Secure Shell (SSH), Internet Control Message Protocol (ICMP)
  • C. Defined virtual server traffic, Secure Shell (SSH), Centralized Management Infrastructure (CMI)
Answer: A
Explanation:
Port Lockdown controls which ports and protocols aSelf IPwill respond to.
However, certain traffic types bypass Port Lockdown for BIG-IP functionality and routing integrity.
The three types that areNOT affectedby Port Lockdown are:
1. Defined Virtual Server Traffic
Traffic destined to a Self IP that matches aconfigured virtual serveris always accepted by the BIG-IP, regardless of Port Lockdown settings.
This ensures that traffic processing does not break when administrators restrict Self-IP ports.
2. ICMP (Internet Control Message Protocol)
ICMP (such as ping, traceroute responses, etc.) always passes through a Self IP even when Port Lockdown is set to:
* Allow Default
* Allow None
* Allow Custom
F5 allows ICMP for reachability and diagnostic purposes independent of Port Lockdown rules.
3. Centralized Management Infrastructure (CMI)
CMI includes the internal HA services used for:
* Device Trust
* ConfigSync
* Failover
* Mirroring
These essential HA communications bypass Port Lockdown to prevent accidental cluster failure.
The well-known port for this traffic isTCP 4353, which is always permitted.
Why the other options are incorrect:
Option A:SSHisrestricted by Port Lockdown unless explicitly allowed.
Option B:Same issue - SSH does not bypass Port Lockdown.
OnlyDefined VS Traffic,ICMP, andCMIbypass Port Lockdown.
