F5 F5 Certifications 301A Questions & Answers

• Question 61:

  Refer to the exhibit.

  

  The http monitor is applied to a pool. All members are enabled. One server responds as follows.

  

  What is the resulting status of this poo! member?

  A. Offline (Disabled)

  B. Offline (Enabled)

  C. Unavailable (Disabled)

  D. Available (Enabled)

  Correct Answer: B

  The first picture "Send String" and "Receive String" are not clear. Send String should be "GOOD", the response packet does not contain this keyword. Receive Disable String is completely unclear. If the response packet contains the content of Receive Disable String at this time, it will be Available (Disabled), If the content of Receive Disable String is not included, then Offline (Enabled).

• Question 62:

  A custom TCP application using a single server is being migrated to the LTM device. A server is being added to the pool. The application is known to violate the TCP protocol RFC. The application currently works without error from a user perspective. Which virtual server type is appropriate in this situation?

  A. Stateless TCP protocol is not applicable

  B. Performance (Layer 4)-pure layer A forwarding

  C. forwarding (Layer 2) pure routing forwarding, pool cannot be specified

  D. Standard-tcp profile exists, RFC verification will be performed

  Correct Answer: B

• Question 63:

  An LTM device receives a response string containing "error" Which monitor type and parameter will mark the HTTP server as down?

  A. HTTP monitor, Receive String "error", and set the Reverse option to Yes

  B. HTTP monitor and Receive String "error'' ... flag is up

  C. HTTP monitor. Receive String "down", and set the Reverse option to Yes .... flag is

  D. HTTP monitor and Receive Disable String "error'' .... flag is disable

  Correct Answer: A

• Question 64:

  An LTM Specialist needs to deploy a virtual server that will load balance traffic targeting https:// register.example.com to a set of three web servers. Persistence needs to be ensured. No persistence mirroring is allowed SSL offloading is required. A fourth web server with fewer resources will be used to handle requests from engine bots to https://register.example.comvrobots.txt by an iRule. The (Rule will use the HTTP_REQUEST event. . What are the required profile and persistence settings to implement this

  A. tcp. dientssl, hup, source address persistence

  B. tcp, clientssl, http. cookie persistence

  C. tcp, clientssl, serverssl, ssl persistence

  D. tcp, clientssl, http, serverssl cookie persistence

  Correct Answer: B

  The option is wrong, it should be clientssl and serverssl. If the title requires ssl offload instead of encryption, you need clientssl instead of serverssl. irule needs HTTP profile to enable HTTP_REQU T. If the session cannot be mirrored, the cookie session remains to meet the demand.

• Question 65:

  An LTM Administrator receives an email from the NOC stating that the switch connected to the backend server was shut down for maintenance. The BIG-IP device handles only UDP traffic. The BIG IP device did not fail over to a DR location when no pool members were available. When the LTM Administrator checks the pool, it confirms that the monitor is still marking UP the pool member. A tcpdump of the traffic shows the following output:

  

  A list of the monitor configuration shows the following:

  

  Which two modifications to the LTM configuration will mark this pool member down, when the switch is down? (Choose two.)

  A. increase the timeout to three times the interval

  B. add a reverse string to the game monitor

  C. enable reverse and wait for the next connection

  D. also assign a gatewayjcmp monitor to the pool

  E. enable manuai-resume on the same monitor

  Correct Answer: BD

• Question 66:

  An LTM Specialist needs to create an iRule that creates persistence records based on a JSESSIONID

  cookie. If a persistence record already exists, then the iRule must persist the client connection according to

  the existing record.

  Which persistence profile enables the iRule to meet these requirements?

  A. Universal

  B. SSL

  C. Destination Address Affinity

  D. Cookie

  E. Source Address Affinity

  Correct Answer: A

• Question 67:

  Exhibit.

  

  The server team has recently configured the three new DNS servers shown for the data center. No current DNS servers are currently configured on the LTM device. Which command should be used to configure the LTM device to use the new DNS servers?

  A. tmsh create/systins name-servers add {192 168.1.2.192.168.100.1O0.192.168.2O0.2OO}

  B. tmsh change /sysdns name-servers add {192.168.1.2.192.168.100.100.192.168.200.200}

  C. tmsh modify/sysdns name-servers add {192.168.1.2.192.168.100.100.192.168.200.200}

  D. tmsh set/sysdns name-servers add {192.168.2.192.168.100.100.192.168.200.200}

  Correct Answer: C

  Modify the configuration with modify, and create the configuration with create. Excluding B and D, and the question is to modify the DNS pointer of E5 itself the need to use is modify.

• Question 68:

  One LTM device in an HA pair of LTM devices is unable to reach its default gateway. An HA Failover event

  needs to happen.

  Which configuration item enables this behavior?

  A. iRule

  B. Gateway Fail Safe

  C. Gateway pool monitor

  D. Gateway pool

  Correct Answer: B

• Question 69:

  An LTM device load balances a pool of routers. The LTM device needs to verify path availability to an

  HTTP server with the IP address 192 168.10 10. located beyond the routers.

  Which monitor type and parameters arc required?

  A. HTTP monitor alias address 192 168.10 10. and set the alias to port 80

  B. TCP monitor, alias address 192.168.10.10. and set the alias to port 80

  C. TCP monitor change transparent option to Yes. set alias address 192.168.10.10. and set the alias to port 80

  D. TCP monitor, change transparent option to Yes, and sot the alias to port 80

  Correct Answer: C

• Question 70:

  An LTM Specialist needs to assign a health monitor to a pool with two pool members 10.10.10 101 and

  10.10.10.102 Both pool members are listening on port 8080 with TCP. The health of the application depends on the health of an another server (10 10 10 100) that runs port 9080 with TCP. Which two custom TCP monitors should be selected as the pool's health monitors' (Choose two)

  A. a custom TCP monitor that works on port 9080 with 10.10.10.100 as alias address

  B. a custom TCP monitor that works on port 9080,

  C. a custom TCP monitor that works on port 8080

  D. a custom TCP monitor that works on port 9080 with 10,10.10.101 as alias address

  E. a custom TCP monitor that works on port 8080 with 10.10.10.101 as alias address

  F. a custom TCP monitor that works on port 8080 with 10.10.10.102 is alias address

  Correct Answer: AC
