F5 F50-531 Online Questions & Answers

• Question 91:

  A site wishes to perform source address translation on packets arriving from the Internet for clients using some pools but not others. The determination is not based on the client's IP address, but on the pool they are load balanced to. What could best accomplish this goal?

  A. A SNAT for all addresses could be defined, and then disable the SNAT processing for select pools.
  B. The decision to perform source address translation is always based on VLAN. Thus, the goal cannot be achieved.
  C. For each virtual server, regardless their default load balancing pools, association with SNAT pools could vary dependent upon need.
  D. The decision to perform source address translation is always based on a client's address (or network). Thus, this goal cannot be achieved.
  A. A SNAT for all addresses could be defined, and then disable the SNAT processing for select pools.

• Question 92:

  What is required for a virtual server to support clients whose traffic arrives on the internal VLAN and pool members whose traffic arrives on the external VLAN?

  A. That support is never available.
  B. The virtual server must be enabled for both VLANs.
  C. The virtual server must be enabled on the internal VLAN.
  D. The virtual server must be enabled on the external VLAN.
  C. The virtual server must be enabled on the internal VLAN.

• Question 93:

  How is persistence configured?

  A. Persistence is an option within each pool's definition.
  B. Persistence is a profile type; an appropriate profile is created and associated with virtual server.
  C. Persistence is a global setting; once enabled, load-balancing choices are superseded by the persistence method that is specified.
  D. Persistence is an option for each pool member. When a pool is defined, each member's definition includes the option for persistence.
  B. Persistence is a profile type; an appropriate profile is created and associated with virtual server.

• Question 94:

  A site needs a virtual server that will use an iRule to parse HTTPS traffic based on HTTP header values. Which two profile types must be associated with such a virtual server? (Choose two.)

  A. TCP
  B. HTTP
  C. HTTPS
  D. ServerSSL
  A. TCP
  B. HTTP

• Question 95:

  Which three properties can be assigned to nodes? (Choose three.)

  A. ratio values
  B. priority values
  C. health monitors
  D. connection limits
  E. load-balancing mode
  A. ratio values
  C. health monitors
  D. connection limits

• Question 96:

  A site has six members in a pool. All of the servers have been designed, built, and configured with the same applications. It is known that each client's interactions vary significantly and can affect the performance of the servers. If traffic should be sent to all members on a regular basis, which load-balancing mode is most effective if the goal is to maintain a relatively even load across all servers?

  A. Ratio
  B. Priority
  C. Observed
  D. Round Robin
  C. Observed

• Question 97:

  Generally speaking, should the monitor templates be used as production monitors or should they be customized prior to use?

  A. Most templates, such as http and tcp, are as effective as customized monitors.
  B. Monitor template customization is only a matter of preference, not an issue of effectiveness or performance.
  C. Most templates, such as https, should have the receive rule customized to make the monitor more robust.
  D. While some templates, such as ftp, must be customized, those that can be used without modification are not improved by specific changes.
  C. Most templates, such as https, should have the receive rule customized to make the monitor more robust.

• Question 98:

  Which two statements are true about SNATs? (Choose two.)

  A. SNAT's are enabled on all VLANs, by default.
  B. SNAT's can be configured within a Profile definition.
  C. SNAT's can be configured within a Virtual Server definition.
  D. SNAT's are enabled only on the VLAN where origin traffic arrives, by default
  A. SNAT's are enabled on all VLANs, by default.
  C. SNAT's can be configured within a Virtual Server definition.

• Question 99:

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

  A. Communication between the systems cannot be effected by port lockdown settings.
  B. Data for both connection and persistence mirroring are shared through the same TCP connection.
  C. Regardless of the configuration, some data is communicated between the systems at regular intervals.
  D. Connection mirroring data is shared through the serial fail-over cable unless network fail-over is enabled.
  B. Data for both connection and persistence mirroring are shared through the same TCP connection.
