Example Questions

Which statement is true concerning cookie persistence? How is persistence configured? As a part of the Setup Utility, the administrator sets the host name for the BIG-IP. What would be the result if the two systems in a redundant pair were set to the same host name? 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 virtual server is listening at 10.10.1.100:any and has the following iRule associated with it: when CLIENT_ACCEPTED { if {[TCP::local_port] equals 80 } { pool pool1 } elseif {[TCP::local_port] equals 443 } { pool pool2 } If a user connects to 10.10.1.100 and port 22, which pool will receive the request? Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If the origin server were to initiate traffic via the BIG-IP, what changes, if any, would take place when the BIG-IP processes such packets? How is MAC masquerading configured? If a client's browser does not accept cookies, what occurs when the client connects to a virtual server using cookie persistence? Which statement is true concerning iRule events? Which two can be a part of a virtual server's definition? (Choose two.) Assuming there are open connections through an active system's virtual servers and a fail-over occurs, by default, what happens to the connections? Generally speaking, should the monitor templates be used as production monitors or should they be customized prior to use? Which IP address will the client address be changed to when SNAT automap is specified within a Virtual Server configuration? Which statement is true regarding fail-over? When using the setup utility to configure a redundant pair, you are asked to provide a "Failover Peer IP". Which address is this? Which statement is true concerning a functional iRule? Under what condition must an appliance license be reactivated? Which statement is true concerning SNATs using automap? Which statement is true concerning SSL termination? What is the purpose of provisioning? A virtual server is listening at 10.10.1.100:80 and has the following iRule associated with it: when HTTP_REQUEST { if { [HTTP::header User-Agent] contains "MSIE" } { pool MSIE_pool } else { pool Mozilla_pool } If a user connects to http://10.10.1.100.html and their browser does not specify a User-Agent, which pool will receive the request? A site would like to ensure that a given web server's default page is being served correctly prior to sending it client traffic. Theye assigned the default HTTP monitor to the pool. What would the member status be if it sent an unexpected response to the GET request? When configuring a Virtual Server to use an iRule with an HTTP_REQUEST event, which lists required steps in a proper order to create all necessary objects? Where is connection mirroring configured? Which event is always triggered when the client sends data to a virtual server using TCP? Which statement is true about the synchronization process, as performed by the Configuration Utility or by typing b config sync all? The ICMP monitor has been assigned to all nodes. In addition, all pools have been assigned custom monitors. The pool is marked available In addition, all pools have been assigned custom monitors. If a pool is marked available (green) which situation is sufficient to cause this? What is the purpose of floating self-IP addresses? A virtual server at 10.10.1.100:80 has the rule listed below applied. when HTTP_REQUEST { if {[HTTP::uri] ends_with "htm" } { pool pool1 } elseif {[HTTP::uri] ends_with "xt" } { pool pool2 } If a user connects to http://10.10.1.100/foo.txt which pool will receive the request? A standard virtual server has been associated with a pool with multiple members. Assuming all other settings are left at their defaults, which statement is always true concerning traffic processed by the virtual server? A site has six members in a pool. Three of the servers are new and have more memory and a faster processor than the others. Assuming all other factors are equal and traffic should be sent to all members, which two load-balancing methods are most appropriate? (Choose two.) Which is an advantage of terminating SSL communication at the BIG-IP rather than the ultimate web server? Assuming other fail-over settings are at their default state, what would occur if the fail-over cable were to be disconnected for five seconds and then reconnected? A standard virtual server is defined with a pool and a SNAT using automap. All other settings for the virtual server are at defaults. When client traffic is processed by the BIG-IP, what will occur to the IP addresses? Which two statements describe differences between the active and standby systems? (Choose two.) Which statement is true concerning the default communication between a redundant pair of BIG-IP devices? Assume the bigd daemon fails on the active system. Which three are possible results? (Choose three.) Given that VLAN fail-safe is enabled on the external VLAN and the network that the active BIG- IP's external VLAN is connected to has failed, which statement is always true about the results? Which two statements are true about SNATs? (Choose two.) Which three properties can be assigned to nodes? (Choose three.) What is the purpose of MAC masquerading? Which cookie persistence method requires the fewest configuration changes on the web servers to be implemented correctly? Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If a client were to initiate traffic to the NAT address, what changes, if any, would take place when the BIG-IP processes such packets? Which two methods can be used to determine which BIG-IP is currently active? (Choose two.) Assume a virtual server is configured with a ClientSSL profile. What would the result be if the virtual server's destination port were not 443? Which action will take place when a failover trigger is detected by the active system? Which statement describes a typical purpose of iRules? You have created a custom profile named TEST2. The parent profile of TEST2 is named TEST1. If additional changes are made to TEST1, what is the effect on TEST2? When configuring a pool member's monitor, which three association options are available? (Choose three.) When network fail-over is enabled, which of the following is true?
