F5 BIG-IP Administration Data Plane Concepts (F5CAB2) Certification Sample Questions

01. Which HA mechanism monitors traffic flowing through a specified VLAN and can trigger failover when traffic is lost for the configured timeout period?
a) Source address affinity
b) VLAN fail-safe
c) SNAT automap
d) Fast L4

02. BIG-IP receives traffic for a destination that belongs to a connected application VLAN. Which local BIG-IP address is the most likely egress IP used on that VLAN for routed traffic?
a) The VLAN-associated self IP
b) The management interface IP
c) The virtual server address
d) The pool member address

03. Which virtual server type would best fit a requirement to accelerate HTTP request handling through a profile-based optimization model rather than basic pool-only processing?
a) Reject virtual server
b) Forwarding IP server
c) Performance HTTP server
d) Stateless UDP server

04. For an active-active BIG-IP configuration, which failover method does F5 explicitly require instead of hard-wired serial failover?
a) Connection mirroring is required
b) Gateway fail-safe is required
c) Auto-failback is required
d) Network failover is required

05. Which virtual server type is most appropriate when BIG-IP should simply forward traffic based on the destination in the client request and there are no pool members to load balance?
a) Standard
b) Forwarding (IP)
c) Reject
d) Performance (HTTP)

06. An administrator reviews a VLAN and sees interface 1.5 marked as Untagged. What traffic behavior should be expected on that interface?
a) It carries only route traffic
b) It carries every VLAN
c) It carries only sync traffic
d) It carries only that VLAN

07. In BIG-IP, which object receives client traffic on a destination IP address and service, then directs that traffic according to the configured application logic?
a) Node
b) Pool Member
c) Virtual Server
d) Self IP

08. A BIG-IP administrator wants to build a trunk from interfaces 1.1 and 1.2 for increased bandwidth and link redundancy. Which statement must be true before assigning interface 1.1 to that trunk?
a) The interface must already be tagged in every VLAN that will use the trunk
b) The interface must be untagged and can belong to only one trunk
c) The interface must already have a self IP assigned
d) The interface must be in a floating traffic group

09. Which BIG-IP object is the front-end listener that receives client traffic on a destination IP address and service?
a) A virtual server listener
b) A pool member endpoint
c) A self IP address
d) A route domain entry

10. A client packet arrives for destination IP 203.0.113.10, but no specific virtual server matches that exact address. A wildcard virtual server with destination 0.0.0.0:any exists. Which traffic behavior should the administrator expect?
a) The packet is dropped immediately because wildcard virtual servers are evaluated first and then rejected
b) The packet is sent directly to the default gateway without LTM processing
c) The packet is matched to the wildcard virtual server because no specific destination match exists
d) The packet is translated to the management IP address
