A failover has just occured on BIG-IP1. BIG-IP2 is now active and manages traffic as expected. Both Bigip's are set with a gateway failsafe to check the reachability of the main border router. Switches have performed as expected.
Where should the LTM Specialist check for potential issues?

• A.Network Interface 1.1 of BIG-IP 2
• B.Network Interface 2.2 of BIG-IP 1
• C.Network Interface 1.1 of BIG-IP 1
• D.Network Interface 2.1 of BIG-IP 1
• E.Network Interface 2.1 of BIG-IP 2
• F.Network Interface 2.2 of BIG-IP 2

An LTM device has a virtual server configured as a Performance Layer 4 virtual listening on
0.0.0.0:0 to perform routing of packets to an upstream router. The client machine at IP address
192.168.0.4 is attempting to contact a host upstream of the LTM device on IP address 10.0.0.99.
The network flow is asymmetrical, and the following TCP capture displays:
# tcpdump -nnni 0.0 'host 192.168.0.4 and host 10.0.0.99' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on 0.0, link-type EN10MB (Ethernet), capture size 96 bytes

Which option within the fastL4 profile needs to be enabled by the LTM Specialist to prevent the LTM device from rejecting the flow?

• A.Loose Initiation
• B.Loose Close
• C.Reset on Timeout
• D.Generate Initial Sequence Number

An LTM Specialist is investigating reports that users are unable to perform some commands through an FTP virtual server. The users are receiving the FTP error "500 Illegal PORT command." The virtual server is configured to SNAT using automap. The LTM Specialist performs a capture on the server side of the LTM device.
Why is the server returning this error?

• A.Active IP address in PORT command
• B.LIST command disallowed
• C.Active IP address in LOGIN command
• D.PORT command disallowed

What does the following iRule do?
when CLIENT_ACCEPTED {
if { [matchclass [IP::client_addr] equals WebClient1-Whitelist1] }{
#log local0. "Valid client IP: [IP::client_addr] - forwarding traffic"
#Pool WebClient1
} else {
log local0. "Invalid client IP: [IP::client_addr] - discarding"
discard
}
}

• A.The iRule compares a client IP to a list. If the client IP is on the list, discard and log the discard.
• B.The iRule compares a client IP to a list. If the client IP is NOT on the list, the client is sent to Pool WebClient1. Otherwise, discard and log the discard.
• C.The iRule compares a client IP to a list. If the client IP is on the list, the client is sent to Pool WebClient1. Otherwise, discard and log the discard.
• D.The iRule compares a client IP to a list. If the client IP is NOT on the list, discard and log the discard.

An LTM Specialist sets up AVR alerts and notifications for a specific virtual server if the server latency exceeds 50ms. The LTM Specialist simulates a fault so that the server latency is consistently exceeding the 50ms threshold; however, no alerts are being received.
Which configuration should the LTM Specialist modify to achieve the expected results?

• A.The metric "Page Load Time" needs to be enabled to ensure that the correct information is collected.
• B.SNMP alerting should be enabled to allow e-mail to be sent to the support team.
• C.The rule should be adjusted to trigger when server latency is above 50ms.
• D.User Agents needs to be enabled to ensure the correct information is collected to trigger the alert.
