問題 #25
Active connections to pool members are unevenly distributed. The load balancing method is Least Connections (member). Priority Group Activation is disabled.
What is a potential cause of the uneven distribution? (Choose one answer)
答案：B
解題說明：
With Least Connections (member), BIG-IP attempts to send new connections to the pool member with the fewest current connections. In a perfectly "stateless" scenario (no affinity), this often trends toward a fairly even distribution over time.
However, persistence overrides load balancing:
* When a persistence profile is applied, BIG-IP will continue sending a client (or client group) to the same pool member based on the persistence record (cookie / source address / SSL session ID, etc.).
* This means even if another pool member has fewer connections, BIG-IP may still select the persisted member to honor session affinity.
* The result can be uneven active connection counts, even though the configured load balancing method is Least Connections.
Why the other options are not the best cause:
* A. Priority Group Activation is disabledPriority Group Activation only affects selection when priority groups are configured; disabling it does not inherently create uneven distribution under Least Connections.
* B. SSL Profile Server is appliedA server-side SSL profile affects encryption to pool members, but it does not by itself cause skewed selection across pool members. (Skew could happen indirectly if members have different performance/latency, but that's not the primary, expected exam answer.)
* D. Incorrect load balancing methodLeast Connections is a valid method and does not itself explain unevenness unless something is overriding it (like persistence) or pool members are not all eligible.
Conclusion:
A persistence profile is the most common and expected reason that active connections become unevenly distributed, because persistence takes precedence over the Least Connections load-balancing decision.
問題 #26
A virtual server is listening at 10.10.1.100:80 and has the following iRule associated with it:
when HTTP_REQUEST { if { [HTTP::header UserAgent] contains "MSIE" }
{ pool MSIE_pool }
else { pool Mozilla_pool }
If a user connects to http://10.10.1.100/foo.html and their browser does not specify a UserAgent, which pool will receive the request?
答案：B
問題 #27
In the GUI, where should the BIG-IP Administrator configure an existing VLAN named external to a specific interface as untagged?
答案：B
解題說明：
In the BIG-IP system, VLANs are the logical entities that group physical interfaces or trunks together. To modify how a VLAN interacts with an interface, the administrator must navigate to the specific VLAN configuration object.
* VLAN List:This section displays all existing VLANs configured on the system.
* Interface Association:Within the properties of a specific VLAN (in this case, "external"), there is an Interfacessection. This is where physical ports or trunks are assigned to the VLAN.
* Tagging Status:For each associated interface, the administrator can choose betweenTagged(802.1Q) or Untagged.
* Untagged:The interface will treat incoming traffic without a VLAN header as part of this VLAN, and outgoing traffic will not have a VLAN tag added. An interface can only be "Untagged" for one VLAN.
* Tagged:Allows an interface to carry traffic for multiple VLANs simultaneously by using 802.1Q headers.
問題 #28
The BIG-IP Administrator disables all pool members in a pool. Users are still able to reach the pool members.
What is allowing users to continue to reach the disabled pool members?
答案：B
問題 #29
A development team needs to apply a software fix and troubleshoot one of its servers. The BIG-IP Administrator needs to immediately remove all connections from the BIG-IP system to the back-end server.
The BIG-IP Administrator checks the Virtual Server configuration and finds that a persistence profile is assigned to it. What should the BIG-IP Administrator do to meet this requirement?
答案：D
解題說明：
Managing the lifecycle of a pool member requires understanding the difference between "Disabled" and
"Forced Offline" states, especially when persistence is involved.
* Disabled (User-Disabled): This state allows existing connections and persistent sessions to continue until they naturally time out or are closed by the client/server. It only preventsnewsessions from being established.
* Forced Offline: This state is more restrictive; it allows existing connections to complete butrejectsall new connections, including those with existing persistence records.
* Immediate Removal: Neither "Disabled" nor "Forced Offline" will instantly kill currently active, established TCP connections. To meet the requirement of "immediately" removing all connections, the administrator must first set the member toForced Offline(to prevent persistence from bringing in new traffic) and then use the command line (e.g., tmsh delete sys connection ss-server-addr [IP]) to clear the current connection table entries.
