F5 BIG-IP v10.x LTM Essentials V10.x - F50-531 模擬練習

A. to prevent ARP cache errors

B. to minimize ARP entries on routers

C. to allow both BIG-IP devices to simultaneously use the same MAC address

D. to minimize connection loss due to ARP cache refresh delays

A. The fail-over cable status is ignored. Fail-over is determined by the network status only.

B. Either a network failure or loss of voltage across the fail-over cable will cause a fail-over.

C. A network failure will not cause a fail-over as long as there is a voltage across the fail-over cable.

D. The presence or absence of voltage over the fail-over cable takes precedence over network fail-over.

A. ClientSSL

B. TCP

C. HTTP

D. HTTPS

E. ServerSSL

A. Cookie persistence uses a cookie that stores the virtual server, pool name, and member IP address in clear text.

B. Cookie persistence allows persistence even if the data are encrypted from client to pool member.

C. If a client's browser accepts cookies, cookie persistence will always cause a cookie to be written to the client's file system.

D. Cookie persistence allows persistence independent of IP addresses.

A. Regardless of the configuration, some data is communicated between the systems at regular intervals.

B. Connection mirroring data is shared through the serial fail-over cable unless network fail-over is enabled.

C. Communication between the systems cannot be effected by port lockdown settings.

D. Data for both connection and persistence mirroring are shared through the same TCP connection.

A. HTTP_RESPONSE

B. CLIENT_ACCEPTED

C. SERVER_SELECTED

D. HTTP_REQUEST

E. CLIENT_DATA

F. SERVER_CONNECTED

G. SERVER_DATA

A. The active system will fail-over and the standby system will go into active mode.

B. The active system will restart the traffic management module to eliminate the possibility that BIG-IP is the cause for the network failure.

C. The active system will reboot and the standby system will go into active mode.

D. The active system will note the failure in the HA table.

A. rule(s)

B. profile(s)

C. persistence type

D. monitor(s)

E. load-balancing mode

A. The decision to perform source address translation is always based on a client's address (or network). Thus, this goal cannot be achieved.

B. For each virtual server, regardless their default load balancing pools, association with SNAT pools could vary dependent upon need.

C. The decision to perform source address translation is always based on VLAN. Thus, the goal cannot be achieved.

D. A SNAT for all addresses could be defined, and then disable the SNAT processing for select pools.
