F5CABR is a 50-item, 60-minute multiple-choice recertification exam with a 245 scaled passing score. It costs US$100 through Certiverse online or US$130 at a Pearson VUE test center. Anyone who previously achieved F5-CA, BIG-IP may take it regardless of expiration date; first-time candidates use the F5CAB1 through F5CAB5 path. Prepare across all five official blueprint modules rather than treating the exam as a single generic administration domain.

Sample F5CABR (BIG-IP Recert) Practice Questions

Try these sample questions to test your F5CABR (BIG-IP Recert) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1An administrator needs to verify the running BIG-IP version and hotfix level from the CLI. Which TMSH command provides this information?
A.tmsh show /sys version
B.tmsh list /sys global-settings
C.tmsh show /sys hardware
D.tmsh show /cm device
Explanation: `tmsh show /sys version` displays the BIG-IP product, base version (for example 17.1.1), build, edition, and hotfix designation, which is exactly what is needed to confirm the patch level on a managed device.
2Which TMSH module is used to configure self IPs, VLANs, and trunks on BIG-IP?
A./cm
B./ltm
C./net
D./sys
Explanation: Networking objects such as VLANs, trunks, self IPs, routes, and route domains are configured under the `/net` module in TMSH. Commands like `tmsh create /net self ...` and `tmsh list /net vlan` operate here.
3Which file format does a UCS archive use, and what does it contain?
A.A plain text SCF script with only LTM configuration
B.A compressed tar archive containing the full system configuration, certificates, license, and SSL keys
C.An XML file with only the running configuration
D.A binary database snapshot of the connection table
Explanation: A UCS (User Configuration Set) is a compressed tar archive that captures full system configuration, including bigip.conf, bigip_base.conf, certificates and keys, license, user accounts, and (optionally) saved configuration that allows full restoration to the same or compatible platform.
4An administrator wants to migrate only the LTM configuration text from one BIG-IP to another, omitting the license and certificates. Which artifact is most appropriate?
A.UCS archive
B.Quick View diagnostic archive (qkview)
C.SCF (Single Configuration File)
D.iHealth report
Explanation: An SCF is a single text file that exports configuration without binary data such as licenses, certificates, or keys. It is the recommended artifact when migrating configuration text to a different system.
5Which BIG-IP utility is used to collect a diagnostic snapshot for analysis by F5 Support?
A.qkview
B.tcpdump
C.iControl REST
D.sosreport
Explanation: `qkview` collects logs, configuration, hardware information, and runtime stats into a single archive that can be uploaded to iHealth (ihealth.f5.com) or attached to an F5 Support case for analysis.
6Where can an administrator upload a qkview to receive automated diagnostic analysis?
A.F5 DevCentral
B.F5 iHealth
C.F5 University
D.F5 BIG-IQ
Explanation: iHealth (ihealth.f5.com) parses an uploaded qkview against a database of known issues and best-practice heuristics, returning a list of diagnostic findings, software lifecycle warnings, and recommended actions.
7Which directory contains the LTM-related log file `ltm` on a BIG-IP system?
A./var/log/
B./var/local/ucs/
C./config/
D./shared/log/
Explanation: BIG-IP system logs, including /var/log/ltm, /var/log/audit, /var/log/messages, /var/log/apm, and /var/log/asm, are stored under /var/log/. The `ltm` log captures pool member up/down events, monitor failures, and LTM-related daemons.
8When BIG-IP audit logging is enabled for configuration changes, which file receives the audit entries?
A./var/log/ltm
B./var/log/audit
C./var/log/messages
D./var/log/secure
Explanation: /var/log/audit is the dedicated audit log for enabled MCP configuration-change auditing, including the user and the configuration operation. The configured audit level determines which management activity is recorded.
9A virtual server has type Standard. Which characteristic is true?
A.BIG-IP forwards packets without inspecting Layer 7 content
B.BIG-IP terminates the client connection and proxies to the pool member as a full proxy
C.BIG-IP rewrites only Layer 2 headers
D.BIG-IP responds with TCP RST to all incoming traffic
Explanation: A Standard virtual server is a full proxy. BIG-IP terminates the client TCP connection on the client side (TMM client-side flow), then opens a separate connection to the selected pool member on the server side, which is required for SSL offload, HTTP profile, OneConnect, persistence, and iRules.
10Which virtual server type uses the FastL4 profile and the ePVA hardware acceleration where available?
A.Standard
B.Performance (Layer 4)
C.Performance (HTTP)
D.Forwarding (IP) virtual server
Explanation: A Performance (Layer 4) virtual server uses the FastL4 profile, which can offload connection state to the embedded Packet Velocity Acceleration (ePVA) chip on supported hardware. It accelerates simple Layer 4 load balancing where Layer 7 features are not needed.

F5CABR (BIG-IP Recert) Study Tips from Top Performers

1Memorize the virtual server types: Standard, Performance L4 (FastL4 + ePVA), Performance HTTP, Forwarding IP/L2, Stateless, Reject, Internal, and DHCP — and which features each supports
2Review monitor math: F5 best practice is Timeout = (3 × Interval) + 1, and learn the difference between TCP, TCP Half Open, HTTP, HTTPS, and External monitors
3Refresh DSC concepts: Sync-Failover vs Sync-Only device groups, traffic groups for Active-Standby vs Active-Active, and how floating self IPs follow traffic group ownership
4Re-practice TMSH paths — /sys, /ltm, /cm, /net — and know where common items live (NTP under /sys, virtual servers under /ltm, device groups under /cm, self IPs under /net)
5Be fluent with diagnostics: qkview to iHealth, /var/log/ltm and /var/log/audit, and tcpdump with the 0.0:nnn noise filter to capture both client- and server-side TMM flows
6Confirm SSL fundamentals: Client SSL terminates inbound TLS, Server SSL re-encrypts to pool, SNI selects the right Client SSL profile, and OCSP stapling improves handshake performance
