F5 F50-531 Online Questions & Answers

• Question 11:

  A BIG-IP has two load balancing virtual servers at 150.150.10.10:80 and 150.150.10.10:443. The port 80 virtual server has SNAT auto-map configured. There is also a SNAT configured at 150.150.10.11 set for a source address range of

  200.200.1.0 / 255.255.255.0. All other settings are at their default states. If a client with the IP address 200.200.1.1 sends a request to https://150.150.10.10, what is the source IP address when the associated packet is sent to the pool member?

  A. 200.200.1.1
  B. 150.150.10.11
  C. Floating self IP address on VLAN where the packet leaves the system
  D. Floating self IP address on VLAN where the packet arrives on the system
  B. 150.150.10.11

• Question 12:

  Which three iRule events are likely to be seen in iRules designed to select a pool for load balancing? (Choose 3)

  A. CLIENT_DATA
  B. SERVER_DATA
  C. HTTP_REQUEST
  D. HTTP_RESPONSE
  E. CLIENT_ACCEPTED
  F. SERVER_SELECTED
  G. SERVER_CONNECTED
  A. CLIENT_DATA
  C. HTTP_REQUEST
  E. CLIENT_ACCEPTED

• Question 13:

  Assuming there are open connections through an active system's NAT and a fail-over occurs, by default, what happens to those connections?

  A. All open connections will be lost.
  B. All open connections will be maintained.
  C. The "Mirror" option must be chosen on the NAT and the setting synchronized prior to the connection establishment.
  D. Long-lived connections such as Telnet and FTP will be maintained while short-lived connections such as HTTP will be lost.
  E. All open connections are lost, but new connections are initiated by the newly active BIG-IP, resulting in minimal client downtime.
  B. All open connections will be maintained.

• Question 14:

  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)
  A. rule(s)
  B. pool(s)

• Question 15:

  What is the purpose of provisioning?

  A. Provisioning allows modules that are not licensed to be fully tested.
  B. Provisioning allows modules that are licensed be granted appropriate resource levels.
  C. Provisioning allows the administrator to activate modules in non-standard combinations.
  D. Provisioning allows the administrator to see what modules are licensed, but no user action is ever required.
  B. Provisioning allows modules that are licensed be granted appropriate resource levels.

• Question 16:

  A virtual server is defined per the charts. The last five client connections were to members C, D, A, B, B. Given the conditions shown in the above graphic, if a client with IP address 205.12.45.52 opens a connection to the virtual server, which member will be used for the connection?

  

  A. 172.16.20.1:80
  B. 172.16.20.2:80
  C. 172.16.20.3:80
  D. 172.16.20.4:80
  E. 172.16.20.5:80
  D. 172.16.20.4:80

• Question 17:

  A site wishes to perform source address translation on packets from some clients but not others. The determination is not based on the client's IP address, but on the virtual servers their packets arrive on. What could best accomplish this goal?

  A. A SNAT for all addresses could be defined, and then disable the SNAT processing for select VLANs.
  B. Some virtual servers could be associated with SNAT pools and others not associated with SNAT pools.
  C. The decision to perform source address translation is always based on VLAN. Thus, the goal cannot be achieved.
  D. The decision to perform source address translation is always based on a client's address (or network). Thus, this goal cannot be achieved.
  B. Some virtual servers could be associated with SNAT pools and others not associated with SNAT pools.

• Question 18:

  A site needs to terminate client HTTPS traffic at the BIG-IP and forward that traffic unencrypted. Which two are profile types that must be associated with such a virtual server? (Choose two.)

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

• Question 19:

  What is the purpose of MAC masquerading?

  A. to prevent ARP cache errors
  B. to minimize ARP entries on routers
  C. to minimize connection loss due to ARP cache refresh delays
  D. to allow both BIG-IP devices to simultaneously use the same MAC address
  C. to minimize connection loss due to ARP cache refresh delays

• Question 20:

  Which event is always triggered when a client initially connects to a virtual server configured with an HTTP profile?

  A. HTTP_DATA
  B. CLIENT_DATA
  C. HTTP_REQUEST
  D. CLIENT_ACCEPTED
  D. CLIENT_ACCEPTED
