最新的 F5-CA F5CAB1 免費考試真題 (Q34-Q39):問題 #34
Refer to the exhibit.

What traffic will be permitted to reach the BIG-IP?
  • A. FTP
  • B. SSH
  • C. Telnet
答案：B
解題說明：
The exhibit shows the configuration of aSelf IPwith:
* Port Lockdown: Allow Custom
* ACustom Listthat 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?
FTP
TCP 21
Not listed
#Not allowed
SSH
TCP 22
Listed
#Allowed
Telnet
TCP 23
Not listed
#Not allowed
Thus,SSHis the only traffic permitted through this Self IP configuration.

問題 #35
The BIG-IP Administrator needs to update access to the Configuration Utility to include the172.28.31.0/24and
172.28.65.0/24networks.
From the TMOS Shell (tmsh), which command should the BIG-IP Administrator use to complete this task?
  • A. modify /sys httpd allow add { 172.28.31.0 172.28.65.0 }
  • B. modify /sys httpd permit add { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 }
  • C. modify /sys httpd allow add { 172.28.31.0/255.255.255.0 172.28.65.0/255.255.255.0 }
答案：C
解題說明：
Access to the BIG-IP Configuration Utility (TMUI) is controlled through the/sys httpd allowlist.
This list defines which IP addresses or subnets are allowed to connect to the management web interface.
To allow two new subnets-172.28.31.0/24and172.28.65.0/24-the administrator mustaddboth subnets to the existing list without removing current entries.
In tmsh, subnet entries must be specified innetwork/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 } Why the other options are incorrect:
Option B:
* IPs are listed without masks, which is invalid for subnet-based access control.
* The system requiresnetwork/netmaskformat.
Option C:
* The command uses permit instead of allow, which is not a valid attribute of /sys httpd.
* The correct keyword must beallow.
Thus, onlyOption Acorrectly adds both permitted subnets in the proper tmsh format.

問題 #36
What are the two options for securing a BIG-IP's management interface?
(Choose two.)
  • A. Use the BIG-IP's Self-IP addresses for administrative access rather than the management interface.
  • B. Limiting network access through the management interface to a trusted/secured network VLAN.
  • C. Block all management-interface administrative HTTPS and SSH service ports to prevent access.
  • D. Restrict administrative HTTPS and SSH access to specific IP addresses or IP ranges.
答案：B,D
解題說明：
Securing the BIG-IP management interface is a fundamental administrative responsibility. F5 best practices emphasize restricting who can reach the management port and ensuring that only authorized systems are allowed access.
A). Limiting management access to trusted network segments
F5 recommends placing the management interface on adedicated, isolated, and secured management network or VLAN, rather than exposing it to production or untrusted networks.
This reduces the attack surface by ensuring only trusted segments have visibility to administrative interfaces.
D). Restricting management access by IP or subnet
F5 BIG-IP uses the/sys httpd allowlist (for HTTPS) and configuration options insshd(for SSH) to control which IP addresses or subnets can access the device.
By specifying only known administrative IPs or ranges, unauthorized users cannot reach the login services.
Why the other options are incorrect
B). Blocking all management HTTPS/SSH ports
* This would prevent any administrative access and is not a viable security practice.
C). Using Self-IP addresses for administrative access
* F5 explicitly warns against using Self-IPs for management access unless strictly necessary.
* Self-IPs are exposed to the data plane and should not be used as the primary administrative interface.

問題 #37
A BIG-IP Administrator needs to verify the state of equipment in the data center.
A BIG-IP appliance has asolid yellow indicatoron the status LED.
How should the administrator interpret this LED indicator?
  • A. Appliance is halted or in End-User Diagnostic (EUD) mode
  • B. Appliance is a standby member in a device group
  • C. A warning-level alarm condition is present
  • D. A power supply is NOT operating properly
答案：C
解題說明：
BIG-IP hardware platforms use chassis LEDs to indicate system health states.
Asolid yellow status LEDtypically indicates awarning condition, such as:
* A non-critical hardware alert
* A temperature threshold nearing limit
* A minor fan or sensor irregularity
* Other non-fatal environmental or system conditions
This state reflects awarning-level alarm, meaning the unit is operational but requires investigation.
Why the other options are incorrect
A). Halted or EUD mode
* This is associated with different LED patterns (usually flashing conditions or specific color codes), not a solid yellow status LED.
B). Standby in device group
* HA state is not indicated by the chassis status LED.
* Standby status is alogicaldevice state, not a hardware LED state.
D). Power supply failure
* Power supply indicators use separate LEDs located on each power module (usually flashing amber/red), not the system status LED.
Thus, asolid yellow status indicatorsignifies awarning-level alarm.

問題 #38
An F5 BIG-IP Administrator is asked to report which modules areprovisionedon the BIG-IP.
In which two ways can this be done?
(Choose two.)
  • A. Via TMSH withlist /sys provision
  • B. Via TMSH withshow /sys provision
  • C. Via the GUI atSystem # Resource Provisioning # Module Allocation
  • D. Via the GUI atStatistics # Module Statistics # System
答案：A,C
解題說明：
Provisioning determines:
* Which BIG-IP modules are enabled (LTM, ASM, APM, AFM, DNS, etc.)
* Their provisioning levels (None, Minimal, Nominal, Dedicated)
Two accurate ways to view provisioning settings are:
A). GUI - System # Resource Provisioning # Module Allocation
This is the primary GUI screen showing:
* All modules
* Their provisioning level
* System resource distribution impact
Administrators commonly use this page to confirm or change module provisioning.
D). TMSH - list /sys provision
This tmsh command displays each module and its provisioning level:
sys provision ltm { level nominal }
sys provision asm { level none }
This is the authoritative CLI method for checking module provisioning configurations.
Why the other options are incorrect:
B). show /sys provision
* Showsruntimeinformation butnot the actual configuration levels.
* list is the correct command for configuration details.
C). Statistics # Module Statistics
* Shows performance statistics, NOT provisioning status.
Therefore, the correct responses areAandD.
