301b Exam Dumps and Practice Questions

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?

-- Exhibit --

-- Exhibit --

Refer to the exhibit.

An LTM Specialist is troubleshooting an issue with SSL and is receiving the error shown when connecting to the virtual server. When connecting directly to the pool member, clients do NOT receive this message, and the application functions correctly. The LTM Specialist exports the appropriate certificate and key from the pool member and imports them into the LTM device. The LTM Specialist then creates the Client SSL profile and associates it with the virtual server.

What is the issue?

An LTM Specialist is working with an LTM device configured with 10 virtual servers on the same domain with a different key/cert pair per virtual. For examplE. www.example.com; ftp.example.com; ssh.example.com; ftps.example.com.

What should the LTM Specialist do to reduce the number of objects on the LTM device?

While investigating the cause of a device failover, an LTM Specialist discovers the following events in /var/log/ltm:

01010029:5: Clock advanced by 518 ticks

01010029:5: Clock advanced by 505 ticks

01010029:5: Clock advanced by 590 ticks

01010029:5: Clock advanced by 568 ticks

01010029:5: Clock advanced by 1681 ticks

01010029:5: Clock advanced by 6584 ticks

01140029:5: HA daemon_heartbeat tmm fails action is failover and restart.

010c0026:5: Failover condition, active attempting to go standby.

Which issue caused the failover?

An LTM Specialist configured a virtual server to load balance a custom application. The application works when it is tested from within the firewall but it fails when tested externally. The pool member address is 192.168.200.10:80. A capture from an external client shows:
