What is a potential cause of the uneven distribution? (Choose one answer)

Priority Group Activation is disabled

SSL Profile Server is applied

A persistence profile is applied

Incorrect load balancing method

QUESTION 41
Which statement is true concerning the default communication between a redundant pair of BIG-IP devices?

Communication between the systems cannot be effected by port lockdown settings.

Data for both connection and persistence mirroring are shared through the same TCP connection.

Regardless of the configuration, some data is communicated between the systems at regular intervals.

Connection mirroring data is shared through the serial fail over cable unless network failover is enabled.

Create a new cluster on device 1

Synchronize the settings of device 1 to the group

Create a new virtual server on device 2

QUESTION 47
A BIG-IP system receives a client connection destined to 1.0.0.10:8080. Multiple virtual servers are configured on the system. Which virtual server will process the connection? (Choose one answer)

A forwarding virtual server configured with 0.0.0.0:any

A forwarding virtual server configured with 1.0.0.10:any (port 0)

A virtual server configured with 0.0.0.0:8080

QUESTION 48
Refer to the exhibit.

During a planned upgrade to a BIG-IP HA pair running Active/Standby, an outage to application traffic is reported shortly after the Active unit is forced to Standby. Reverting the failover resolves the outage. What should the BIG-IP Administrator modify to avoid an outage during the next failover event? (Choose one answer)

The Tag value on the Standby device

The interface on the Active device to 1.1

The Tag value on the Active device

The Interface on the Standby device to 1.1

QUESTION 49
An ecommerce company is experiencing latency issues with online shops during Black Friday’s peak season. The BIG-IP Administrator detects an overall high CPU load on the BIG-IP device and wants to move the top utilized Virtual Servers to a dedicated BIG-IP device. Where should the BIG-IP Administrator determine the problematic Virtual Servers? (Choose one answer)

Local Traffic > Virtual Servers > Virtual Server List

System > Platform

Statistics > Module Statistics > Local Traffic > Virtual Servers

Local Traffic > Network Map

Comprehensive and Detailed Explanation From BIG-IP Administration Data Plane Concepts documents:
When troubleshooting performance and latency issues on BIG-IP, especially under peak load conditions, it is critical to identify which Virtual Servers are consuming the most resources. This is a core data plane analysis task.
BIG-IP provides multiple views of configuration and status, but only certain areas expose real-time and historical traffic statistics that correlate directly with CPU usage and throughput.
Why Option C Is Correct:
Statistics > Module Statistics > Local Traffic > Virtual Servers provides:
Real-time and cumulative statistics per Virtual Server
Metrics such as:
Bits in / Bits out
Packets in / Packets out
Current connections
Connection rate
Total requests
The ability to identify high-traffic or high-connection Virtual Servers, which are the most likely contributors to elevated CPU utilization These statistics allow the administrator to objectively determine which Virtual Servers are the top consumers of system resources and therefore good candidates for migration to a dedicated BIG-IP device.
Why the Other Options Are Incorrect:
A . Local Traffic > Virtual Servers > Virtual Server List
Primarily a configuration view
Does not provide sufficient performance or utilization statistics to identify CPU-heavy Virtual Servers B . System > Platform Displays hardware-level information such as CPU cores, memory, disk, and platform type Does not break down utilization by Virtual Server D . Local Traffic > Network Map Provides a logical topology view of Virtual Servers, pools, and pool members Useful for understanding relationships, but not for identifying high-utilization Virtual Servers Key Data Plane Concept Reinforced:
To diagnose performance problems and plan traffic redistribution, BIG-IP administrators must rely on Module and object-level statistics, not configuration screens. The Virtual Server statistics view is the authoritative location for identifying traffic hotspots that directly impact CPU and latency during peak events such as Black Friday.

QUESTION 50
A BIG-IP Administrator has a cluster of devices. What should the administrator do after creating a new Virtual Server on device 1?

create a new cluster on device 1

create the new virtual server on device 2

synchronize the settings of the group to device 1

synchronize the settings of device 1 to the group

QUESTION 51
Which statement is true concerning cookie persistence?

Cookie persistence allows persistence independent of IP addresses.

Cookie persistence allows persistence even if the data are encrypted from client to pool member.

Cookie persistence uses a cookie that stores the virtual server, pool name, and member IP address in clear text.

If a client’s browser accepts cookies, cookie persistence will always cause a cookie to be written to the client’s file system.

QUESTION 52
What type of virtual server should be used to block responses for one IP in a subnet with a virtual server?
(Choose one answer)

Drop

Block

Reject

Standard

QUESTION 53
Which three iRule events are likely to be seen in iRules designed to select a pool for load balancing? (Choose three.)

CLIENT_DATA

SERVER_DATA

HTTP_REQUEST

HTTP_RESPONSE

CLIENT_ACCEPTED

SERVER_SELECTED

SERVER_CONNECTED

QUESTION 54
The BIG-IP Administrator wants to provide quick failover between the F5 LTM devices that are configured as an HA pair with a single Self IP using the MAC Masquerade feature. The administrator configures MAC masquerade for traffic-group-1 using the following command:
`tmsh modify /cm traffic-group traffic-group-1 mac 02:12:34:56:00:00`
However, the Network Operations team identifies an issue with using the same MAC address across multiple VLANs. As a result, the administrator enables Per-VLAN MAC Masquerade to ensure a unique MAC address per VLAN by running:
`tmsh modify /sys db tm.macmasqaddr_per_vlan value true`
What would be the resulting MAC address on a tagged VLAN with ID 1501? (Choose one answer)

02:12:34:56:01:15

02:12:34:56:dd:05

02:12:34:56:05:dd

02:12:34:56:15:01

QUESTION 55
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 traffic distribution?

Incorrect load balancing method

Priority Group Activation is disabled

SSL Profile (Server) is applied

Persistence profile is applied

QUESTION 56
Which statement is true concerning iRule events?

All iRule events relate to HTTP processes.

All client traffic has data that could be used to trigger iRule events.

All iRule events are appropriate at any point in the clientserver communication.

If an iRule references an event that doesn’t occur during the client’s communication, the client’s connection will be terminated prematurely.

QUESTION 57
A BIG-IP Administrator explicitly creates a traffic group on a BIG-IP device. Which two types of configuration objects can be associated with this traffic group? (Choose two.)

iRules

Application Instances

Virtual Addresses

VLANs

Floating Self IPs
