F5 LTM Specialist 認定 301 試験問題:

1. An LTM has the 3 virtual servers, 2 SNATs, four self IP addresses defined, and the networks shown in the exhibit. Selected options for each object are shown below. Settings not shown are at their defaults.
Assume port exhaustion has not been reached. Vi rtualServerl Destination: 10.10.2.102:80 netmask 255.255.255.255 Pool: Pool with 3 members in the 172.16/16 network SNAT Automap configured Vi rtualServer2 Destination: 10.10.2.102:* netmask 255.255.255.255 Pool: Pool with 3 members in the 192.168/16 network Vi rtualServer3 Destination: 10.10.2.0:80 netmask 255.255.255.0 Type: IP Forwarding SNAT1 Source IP: 10.10.0.0 netmask 255.255.0.0 SNAT Address: SNAT Pool with 2 members
172.16.20.50 and 192.168.10.50 SNAT2 Source IP: All Addresses SNATAddress:
10.10.2.102 Floating Self IPs 192.168.1.1; 172.16.1.1; 10.10.2.1; 10.10.1.1

A) Source IP: 10.10.2.1; Destination IP: 10.10.2.10
B) connection attempt is made with a source IP and port of 10.10.100.50:2222 and a destination IP and port of 10.10.2.10:80. When the request is processed, what will be the source and destination IP addresses?

C) Source IP: Either 172.16.20.50 or 192.168.10.50; Destination IP: 10.10.2.10
D) Source IP: 10.10.2.102; Destination IP 10.10.2.10
E) Source IP: 10.10.2.1; Destination IP: pool in the 172.16/16 network C
F) The request will be droped.

2. What is the expected difference between two source address persistence profiles if profile A has a mask of 255.255.255.0 and profile B has a mask of 255.255.0.0?

A) Profile A will have more clients matching existing persistence records.
B) Profile B has a greater potential number of persistence records.
C) Profile B will have fewer persistence records for the sane client base.
D) There are no detectable differences.

3. How is traffic flow through transparent virtual servers different from typical virtual servers?

A) traffic flow through transparent virtual servers must be forwarded through a single routing device.
B) Traffic flow through transparent virtual servers is bridged ( leave IP and MAC.addresses intact) rather than routed (leave IP address intact but change the MAC.addresses).
C) Traffic flow through transparent virtual severs is not load balabced.
D) traffic flow through transparent virtual servers soes not have IP address translation performed.

4. Which statement describes advanced shell access correctly?
Which statement describes advanced shell access correctly?

A) The context determines which pools are available for load balancing.
B) The context determines the values of commands that vary between client and server.
C) The context determines which events are available for iRule processing.
D) The context has no impact on events.

5. Which statement is true concerning SNATs using SNAT pools and SNATs using automap?

A) SNAT s using automap preferentially translate source addresses to non-floating self-IP addresses.
B) SNAT s using automap translate source addresses randomly to any of the BIG-IP's floating self-IP addresses.
C) A .SNAT pool can contain virtual server addresses.
D) SNAT s using a SNAT pool translate source addresses randomly to any of the addresses in the SNAT pool.
