During the maintenance window.

Before the maintenance window.

After the maintenance window.

6. The Configuration Utility of a BIG-IP device is currently accessible via its management IP 10.53.1.245 from all VLANs.

The BIG-IP Administrator needs to restrict access so only hosts from the 10.0.0.0/24 subnet can access the Configuration Utility.

Which TMSH command accomplishes this?

(tmos)# create /net acl MGM

HTTP rule add { (permit tcp 10.0.0.0 0.0.0.255 host 10.53.1.245 http) }

(tmos)# modify /ltm httpd allow replace-all-with {10.0.0.0/24}

(tmos)# create /net acl MGM

HTTP rule add { (permit tcp 10.0.0.0/24 10.53.1.245 http) (deny ip any any http) }

(tmos)# modify /sys httpd allow replace-all-with {10.0.0.0/24}

7. The BIG-IP Administrator wants to manage the newly built F5 system through an in-band Self-IP.

The administrator has configured a VLAN and Self-IP and can ping the IP from their workstation, but cannot access the system via SSH or HTTPS.

What port lockdown settings should the BIG-IP Administrator use to allow management access on the Self-IP? (Choose two.)

The Self-IP port lockdown behavior could be adjusted to Allow Default

The Self-IP port lockdown behavior could be adjusted to Allow All

The Self-IP port lockdown behavior could be adjusted to Allow Mgmt

The Self-IP port lockdown behavior could be adjusted to Allow Management

8. 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?

modify /sys httpd allow add { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 }

modify /sys httpd allow add { 172.28.31.0 172.28.65.0 }

modify /sys httpd permit add { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 }

9. An F5 VE has been deployed into a VMware environment via an OVF file.

An administrator wants to configure the management IP address so the VE can be accessed for further setup.

Which two are valid methods for configuring the management-ip address? (Choose two.)

Log into the remote console and configure the management IP by running the config executable.

Log into the remote console and configure the management IP through TMSH using: create sys management-ip /

Log into the remote console and configure the management IP through TMSH using: create ltm management-ip /

Log into the remote console and configure the management IP by running the setup command.

10. A BIG-IP Administrator is responsible for deploying a new software image on an F5 BIG-IP HA pair and has scheduled a one-hour maintenance window.

With a focus on minimizing service disruption, which of the following strategies is the most appropriate?

Update the active node first, reboot to the newly updated boot location and verify functionality, then push the update from the active to the standby node and reboot the standby node.

Reset the Device Trust, apply the update to each node separately, reboot both nodes, then re-establish the Device Trust.

Update the standby node first and reboot it to the newly updated boot location, failover to the newly updated node and verify functionality. Repeat the upgrade procedures on the next node, which is now in standby mode.

Update both nodes in the HA pair, then reboot both nodes simultaneously to ensure they run the same software version.

11. A BIG-IP device will be dedicated to functioning as a WAF, requiring only the ASM module to be provisioned.

What provisioning level will ensure that the system allocates all CPU, memory, and disk resources to this module exclusively?

Dedicated

Comprehensive

Maximal

Nominal

12. When using the tmsh shell of a BIG-IP system, which command will display the management-ip address?

run /util bash ifconfig mgmt

list /sys management-ip

show /sys management-ip

13. A BIG-IP Administrator plans to upgrade a BIG-IP device to the latest TMOS version.

Which two tools could the administrator leverage to verify known issues for the target versions? (Choose two.)

F5 End User Diagnostics (EUD)

F5 iHealth

F5 University

F5 Bug Tracker

F5 Downloads

14. What are the two options for securing a BIG-IP’s management interface? (Choose two.)

Limiting network access through the management interface to a trusted/secured network VLAN.

Block all management-interface administrative HTTPS and SSH service ports to prevent access.

Use the BIG-IP’s Self-IP addresses for administrative access rather than the management interface.

Restrict administrative HTTPS and SSH access to specific IP addresses or IP ranges.

15. 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 }
