F5 F5 Certification F50-531 Questions & Answers

• Question 41:

  Which statement accurately describes the difference between two load-balancing modes specified as "member" and "node"?

  A. There is no difference; the two terms are referenced for backward compatibility purposes.

  B. When the load-balancing choice references "node", priority group activation is unavailable.

  C. Load-balancing options referencing "nodes" are available only when the pool members are defined for the "any" port.

  D. When the load-balancing choice references "node", the addresses' parameters are used to make the load-balancing choice rather than the member's parameters.

  Correct Answer: D

• Question 42:

  Which two can be a part of a virtual server's definition? (Choose two.)

  A. rule(s)

  B. pool(s)

  C. monitor(s)

  D. node address(es)

  E. load-balancing method(s)

  Correct Answer: AB

• Question 43:

  Assume a BIG-IP has no NATs or SNATs configured. Which two scenarios are possible when client traffic arrives on a BIG-IP that is NOT destined to a self-IP? (Choose two.)

  A. If the destination of the traffic does not match a virtual server, the traffic will be discarded.

  B. If the destination of the traffic does not match a virtual server, the traffic will be forwarded based on routing tables.

  C. If the destination of the traffic matches a virtual server, the traffic will be processed per the virtual server definition.

  D. If the destination of the traffic matches a virtual server, the traffic will be forwarded, but it cannot be load-balanced since no SNAT has been configured.

  Correct Answer: AC

• Question 44:

  When configuring a pool member's monitor, which three association options are available? (Choose three.)

  A. inherit the pool's monitor

  B. inherit the node's monitor

  C. configure a default monitor

  D. assign a monitor to the specific member

  E. do not assign any monitor to the specific member

  Correct Answer: A

• Question 45:

  The current status of a given pool member is unknown. Which condition could explain that state?

  A. The member has no monitor assigned to it.

  B. The member has a monitor assigned to it and the most recent monitor was successful.

  C. The member has a monitor assigned to it and the monitor did not succeed during the most recent timeout period.

  D. The member's node has a monitor assigned to it and the monitor did not succeed during the most recent timeout period.

  Correct Answer: A

• Question 46:

  The ICMP monitor has been assigned to all nodes. In addition, all pools have been assigned custom monitors. If a pool is marked available (green) which situation is sufficient to cause this?

  A. All of the pool member nodes are responding to the ICMP monitor as expected.

  B. Less than 50% of the pool member nodes responded to the ICMP echo request.

  C. All of the members of the pool have had their content updated recently and their responses no longer match the monitor receive rule.

  D. Over 25% of the pool members have had their content updated and it no longer matches the receive rule of the custom monitor. The other respond as expected.

  Correct Answer: D

• Question 47:

  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.

  Correct Answer: C

• Question 48:

  You have a pool of servers that need to be tested. All of the servers but one should be tested every 10 seconds, but one is slower and should only be tested every 20 seconds. How do you proceed?

  A. It cannot be done. All monitors test every five seconds.

  B. It can be done, but will require assigning monitors to each pool member.

  C. It cannot be done. All of the members of a pool must be tested at the same frequency.

  D. It can be done by assigning one monitor to the pool and a different monitor to the slower pool member.

  Correct Answer: D

• Question 49:

  When can a single virtual server be associated with multiple profiles?

  A. Never. Each virtual server has a maximum of one profile.

  B. Often. Profiles work on different layers and combining profiles is common.

  C. Rarely. One combination, using both the TCP and HTTP profile does occur, but it is the exception.

  D. Unlimited. Profiles can work together in any combination to ensure that all traffic types are supported in a given virtual server.

  Correct Answer: B

• Question 50:

  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

  Correct Answer: AB
