  1. slow start

Question 7

An LTM Specialist is working with an LTM device configured with 10 virtual servers on the same domain with a different key/cert pair per virtual. For examplE. www.example.com; ftp.example.com; ssh.example.com; ftps.example.com. What should the LTM Specialist do to reduce the number of objects on the LTM device?

  1. create a 0 port virtual server and have it answer for all protocols
  2. create a 0.0.0.0:0 virtual server thus eliminating all virtual servers
  3. create a transparent virtual server thus eliminating all virtual servers
  4. create a wildcard certificate and use it on all *.example.com virtual servers

Question 8

The pool members are serving up simple static web content. The current virtual server configuration is given as follows: tmsh list ltm virtual simple ltm virtual simple { destination 10.10.10.10:80 ip-protocol tcp mask 255.255.255.255 profiles { http { } httpcompression { } oneconnect { } tcp { } } snat automap vlans-disabled } tmsh list ltm pool simple_pool ltm pool simple_pool { members { 10.10.10.11:80 { address 10.10.10.11 } 10.10.10.12:80 { address 10.10.10.12 } 10.10.10.12:80 { address 10.10.10.13 } } } Which three objects in the virtual server configuration can be removed without disrupting functionality of the virtual server? (Choose three.)

  1. tcp
  2. http
  3. oneconnect
  4. snat automap
  5. httpcompression

Question 9

An LTM device is running BIG-IP v10.2.0 software. The LTM Specialist is tasked with upgrading the LTM device to BIG-IP v11.2.0 HF1. The LTM Specialist starts the upgrade process by selecting the uploaded Hotfix and installing to an unused volume. After 10 minutes, the LTM Specialist checks the status of the upgrade process and notices that the process is stalled at 0%. What should the LTM Specialist verify?

  1. the selected volume has sufficient space available
  2. the base software version exists on the LTM device
  3. the LTM device has been restarted into maintenance mode
  4. the LTM device has an available Internet connection via the management interface

Question 10

A stand-alone LTM device is to be paired with a second LTM device to create an active/standby pair. The current stand-alone LTM device is in production and has several VLANs with floating IP addresses configured. The appropriate device service clustering (DSC) configurations are in place on both LTM devices. Which two non-specific DSC settings should the LTM Specialist configure on the second LTM device to ensure no errors are reported when attempting to synchronize for the first time? (Choose two.)

  1. pools
  2. VLANs
  3. default route
  4. self IP addresses
