質問 # 102
A node is a member of various pools and hosts different web applications. If a web application is unavailable, the BIG-IP appliance needs to mark the pool member down for that application pool. What should a BIG-IP Administrator deploy at the pool level to accomplish this?

B. A combination of ICMP + TCP monitor
C. A TCP monitor with a custom interval/timeout
D. A UDP monitor with a custom interval/timeout

正解：A

解説：
Explanation
Requiring all traffic to be HTTPS access requires HTTP requests to be redirected directly to HTTPS.

質問 # 103
When network failover is enabled, which of the following is true?

A. A network failure will not cause a failover as long as there is a voltage across the failover cable.
B. The failover cable status is ignored. Failover is determined by the network status only.
C. The presence or absence of voltage over the fail over cable takes precedence over network failover.
D. Either a network failure or loss of voltage across the failover cable will cause a failover.

正解：A

質問 # 104
Refer to the exhibit.

A user notifies the BIG-IP Administrator that http://remote company.com is NOT accessible. Remote access to company resources must be encrypted.
What should the BIG-IP Administrator do to fix the issue?

A. Change the Type of the Virtual Server remote.company.com_vs to Forwarding Requiring all traffic to be HTTPS access requires HTTP requests to be redirected directly to HTTPS.

質問 # 105
A BIG-IP Administrator uses backend servers to host multiple services per server. There are multiple virtual servers and pools defined, referencing the same backend servers.
Which load balancing algorithm is most appropriate to have an equal number of connections on each backend server?

A. Least Connections (member)
B. Least Connections (node)
C. Predictive (member)
D. Predictive (node)

正解：B

解説：
Explanation
The same set of servers provides multiple services, that is, using different ports to provide different services at the same time. The stem requirement is based on server connection balancing, not server + port, so it is node.

質問 # 106
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 BIGElIP, what will occur to the IP addresses.

A. Traffic initiated to the virtual server will have the destination address translated to a pool member address and the source addressTraffic initiated to the virtual server will have the destination address translated to a pool member. address and the source address translated to a selfElIP address.
B. Traffic initiated to the virtual server will have the destination address translated to a pool member address and the source addressTraffic initiated to the virtual server will have the destination address translated to a pool member. address and the source address translated to a selfElIP address. Traffic arriving destined to other destinations will have the source translated to a selfElIP address only.
C. Traffic initiated by the pool members will have the source address translated to a selfElIP address but the destination address will not be changed.
D. Traffic
initiated by selected clients, based
on their IP address, will have the source address translated to a selfElIP address but the destination will only be translated if the traffic is destined to the virtual server.

正解：A

質問 # 107
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?

A. The source address would not change, but the destination address would be translated to the origin address.
B. The destination address would not change, but the source address would be translated to the origin address.
C. The destination address would not change, but the source address would be translated to the NAT's address.
D. The source address would not change, but the destination address would be translated to the NAT's address.

正解：A

質問 # 108
Refer to the exhibit.

How many nodes are represented on the network map shown?

A. Four
B. Two
C. One
D. Three

正解：D

質問 # 109
Refer to the exhibit.

The BIG-IP Administrator has modified an iRule on one device of an HA pair. The BIG-IP Administrator notices there is NO traffic on the BIG-IP device in which they are logged into.
What should the BIG-IP Administrator do to verify if the iRule works correctly?

A. Pull configuration to this device to the cluster and start to monitor traffic on this device
B. Log in to the other device in the cluster, pull configuration to it, and start to monitor traffic on that device
C. Log in to the other device in the cluster, push configuration from it, and start to monitor traffic on that device
D. Push configuration from this device to the group and start to monitor traffic on this device

正解：B

解説：
The device in the picture is a standby machine, of course there is no traffic, you need to log in to the host, and then pull the configuration to the host.

質問 # 110
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.

A. create the Virtual Server, create required pools, create the iRule, edit the Virtual Server
B. create a custom HTTP profile, create required pools, create the Virtual Server, create the iRule
C. create required pools, create a custom HTTP profile, create the iRule, create the Virtual Server
D. create profiles, create the iRule, create required pools, create the Virtual Server

正解：A

質問 # 111
A BIG-IP Administrator is creating a new Trunk on the BIG-IP device. What objects should be added to the new Trunk being created?

A. IP addresses
B. VLANS
C. Interfaces
D. Network routes

正解：C

解説：
Explanation
trunk is a portchannel, you need to add a physical interface.

質問 # 112
Which two statements
describe differences
between the active and standby systems. (Choose two.)

質問 # 114
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 matches a virtual server, the traffic will be forwarded, but it cannot be loadbalanced since no SNAT has been configured.
B. If the destination of the traffic does not match a virtual server, the traffic will be discarded.
C. If the destination of the traffic matches a virtual server, the traffic will be processed per the virtual server definition.
