Question 46

An LTM is configure an application that is separated into several subdomains across multiple virtual servers. Many of these subdomains require encryption and could be accessed by anyone on the internet. The configuration must NOT result in SSL warnings to end users. How should the LTM Specialist configure the SSL profiles for these virtual servers?
  • Question 47

    An LTM Administrator receives an email from the NOC stating that the switch connected to the backend server was shut down for maintenance. The BIG-IP device handles only UDP traffic. The BIG IP device did not fail over to a DR location when no pool members were available.
    When theLTM Administrator checks the pool, it confirms that the monitor is still marking UP the pool member.
    A tcpdump of the traffic shows the following output:

    A list of the monitor configuration shows the following:

    Which two modifications to the LTMconfiguration will mark this pool member down, when the switch is down? (Choose two.)
  • Question 48

    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

    Which option within the fastL4 profile needs to be enabled by the LTM Specialist to prevent the LTM device from rejecting the flow?
  • Question 49

    An LTM Specialist needs to deploy a virtual server that will load balance traffic targeting
    https://register.example.com to a set of three webservers. Persistence needs to be ensured. No persistence mirroring is allowed SSL offloading is required.
    A fourth web server with fewer resources will be used to handle requests from engine bots to
    https://register.example.comvrobots.txt by an iRule. The(Rule will use the HTTP_REQUEST event. .
    What are the required profile and persistence settings to implement this
  • Question 50

    A set of servers is used for an FTP application as well as an HTTP website via separate BIG-IP Pools. The server support team reports that some servers are receiving a lot more traffic than others. Which Load Balancing Method should the BIG-IP Administrator apply to even out the connection count?
