Question 66

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:
GET /index.jsp HTTP/1.1

    - Exhibit --

    -- Exhibit --
    Refer to the exhibit.
    A company uses a complex piece of client software that connects to one or more virtual servers hosted on an LTM device. The client software is experiencing issues. An LTM Specialist must determine the cause of the problem.
    The LTM Specialist has the tcpdump extract and knows the client source IP is 168.210.232.5.
    Assuming no wildcard virtual servers, how many distinct virtual servers does the client connect to on the LTM device?
  • Question 68

    An LTM Specialist is troubleshooting an issue with a new virtual server. When connecting through the virtual server, clients receive the message "Unable to connect" in the browser, although connections directly to the pool member show the application is functioning correctly. The LTM configuration is:
    ltm virtual /Common/vs_https { destination /Common/10.10.1.110:443 ip-protocol udp mask 255.255.255.255 pool /Common/pool_https profiles { /Common/udp { } } translate-address enabled translate-port enabled vlans-disabled }
    ltm pool /Common/pool_https { members { /Common/172.16.20.1:443 { address 172.16.20.1 } } }
    How should the LTM Specialist resolve this issue?
  • Question 69

    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?
  • Question 70

    A new web application is hosted at www.example.net, but some clients are still pointing to the legacy web application at www.example.com.
    Which iRule will allow clients referencing www.example.com to access the new application?
