• Question 462:

  An application is configured on an LTM device:

  Virtual server: 10.0.0.1:80 (VLAN vlan301)

  SNAT IP: 10.0.0.1

  Pool members: 10.0.1.1:8080, 10.0.1.2:8080, 10.0.1.3:8080 (VLAN vlan302)

  Which packet capture should the LTM Specialist perform on the LTM device command line interface to capture only client traffic specifically for this virtual server?

  A. tcpdump -ni 0.0:nnn -s 0 'host 10.0.0.1' -w /var/tmp/trace.cap
  B. tcpdump -ni vlan301 -s 0 'port 80 and host 10.0.0.1' -w /var/tmp/trace.cap
  C. tcpdump -ni vlan301 -s 0 'port 8080 and host 10.0.1.1 or host 10.0.1.2 or host 10.0.1.3' - w /var/tmp/trace.cap
  D. tcpdump -ni vlan302 -s 0 'port 8080 and host 10.0.1.1 or host 10.0.1.2 or host 10.0.1.3' - w /var/tmp/trace.cap
  E. tcpdump -ni 0.0:nnn -s 0 '(port 80 and host 10.0.0.1) or (port 8080 and host 10.0.1.1 or host 10.0.1.2 or host 10.0.1.3)' -w /var/tmp/trace.cap

• Question 463:

  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. An HTTP monitor with custom send/receive strings
  D. A TCP monitor with a custom interval/timeout
  C. An HTTP monitor with custom send/receive strings

• Question 464:

  An organization's development team creates an application to put behind the F5LTM device. The application can be quite load intensive at first, and then evens out over time. The team's load balancing method needs to select a pool after taking into account the pool member's response over the time to avoid landing on a busy pool member.

  Which of the following load balancing methods meets this requirement?

  A. Fastest (application)
  B. Predictive (member)
  C. Dynamic (node)
  D. Observed (member)
  B. Predictive (member)

• Question 465:

• Question 466:

  An LTM device has a virtual server configured as a Performance Layer 4 virtual listening on 0.0.0.0:0 to perform routing of packets to an upstream router. The client machine at IP address 192.168.0.4 is attempting to contact a host upstream of the LTM device on IP address 10.0.0.99. The network flow is asymmetrical, and the following TCP capture displays: # tcpdump -nnni 0.0 'host 192.168.0.4 and host 10.0.0.99' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on 0.0, link-type EN10MB (Ethernet), capture size 96 bytes 05:07:55.499954 IP 192.168.0.4.35345 > 10.0.0.99.443: S 3205656213:3205656213(0) ack 3267995082 win 1480 05:07:55.499983 IP 10.0.0.99.443 > 192.168.0.4.35345: R 1:1(0) ack 1 win 0 05:07:56.499960 IP 192.168.0.4.35345 > 10.0.0.99.443: S 3205656213:3205656213(0) ack 3267995082 win 1480 05:07:56.499990 IP 10.0.0.99.443 > 192.168.0.4.35345: R 1:1(0) ack 1 win 0 4 packets captured Which option within the fastL4 profile needs to be enabled by the LTM Specialist to prevent the LTM device from rejecting the flow?

  B. Loose Initiation
  C. Reset on Timeout
  D. Generate Initial Sequence Number
  B. Loose Initiation
