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.)

A. pools

B. VLANs

C. default route

D. self IP addresses

An LTM Specialist is running the following packet capture on an LTM device:

ssldump -Aed -ni vlan301 'port 443'

Which two SSL record message details will the ssldump utility display by default? (Choose two.)

A. HTTP Version

B. User-Agent

C. ClientHello

D. ServerHello

E. Issuer

An LTM Specialist has configured a virtual server for www.example.com, load balancing connections to a pool of application servers that provide a shopping cart application. Cookie persistence is enabled on the virtual server. Users are able to connect to the application, but the user's shopping cart fails to update. A traffic capture shows the following:

Request: GET /cart/updatecart.php HTTP/1.1 Host: www.example.com Connection: keep-alive Cache-Control: max-age=0 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-EncodinG. gzip,deflate,sdch Accept-LanguagE. en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 CookiE.

No changes can be made to the application.

What should the LTM Specialist do to resolve the problem?

A. Use an iRule to rewrite the cartID cookie domain.

B. Create a universal persistence profile on the cartID cookie.

C. Enable source address persistence as a fallback persistence method.

D. Create a cookie persistence profile with "match across services" enabled.

An LTM device is deployed in a one-armed topology. The virtual server, clients, and web servers are connected on the LTM device internal VLAN. A client tries to connect to the virtual server and is unable to establish a connection. A packet capture from the LTM device internal VLAN shows that the HTTP request is being forwarded to the web server.

From which two additional locations should protocol analyzer data be collected? (Choose two.)

A. network interface of web server

B. network interface of client machine

C. internal VLAN interface of LTM device

D. external VLAN interface of LTM device

E. any network interface of the Internet firewall

An LTM Specialist receives a request to monitor the network path through a member, but NOT the member itself. Which monitor option should the LTM Specialist enable or configure?

A. Reverse

B. Up interval

C. Transparent

D. Alias address

E. Time until up

The active LTM device in a high-availability (HA) pair performs a failover at the same time the network team reports an outage of a switch on the network. Which two items could have caused the failover event? (Choose two.)

A. a VLAN fail-safe setting

B. a monitor on a pool in an HA group

C. the standby LTM that was rebooted

D. an Auditor role that has access to the GUI

E. the standby LTM that lost connectivity on the failover VLAN

In preparation for a maintenance task, an LTM Specialist performs a "Force to Standby" on LTM device Unit 1. LTM device Unit 2 becomes active as expected. The maintenance task requires the reboot of Unit 1. Shortly after the reboot is complete, the LTM Specialist discovers that Unit 1 has become active and Unit 2 has returned to standby.

What would cause this behavior?

A. Unit 1 is set with the redundancy state preference of active in devices groups.

B. Unit 1 is set with the redundancy state preference of active in high availability.

C. A traffic group is configured with Auto Failback, and Unit 1 is the default device.

D. A device group is configured with Auto Failback, and Unit 1 is the default device.

An LTM Specialist is reviewing the 'test' partition.

Which objects, in order, can be removed from the partition?

A. delete pool test1_pool, delete node 10.1.1.2

B. delete node 10.1.1.2, delete pool test2_pool

C. delete pool test1_pool, delete node 10.1.1.2, delete node 10.1.1.1

D. delete virtual test1_vs, delete pool test2_pool, delete node 10.1.1.1

E. delete pool test1_pool, delete pool test2_pool, delete node 10.1.1.3

An HTTP monitor always marks the nodes in the pool as down. The monitor's definition and the HTTP headers from the monitor request and response are provided.

What is the issue?

A. The response is compressed.

B. The send string is incorrect.

C. The monitor timeout is too short.

D. The monitor is NOT configured to follow the redirect.

An LTM Specialist is troubleshooting an HTTP monitor that is marking a pool member as down. Connecting to the pool member directly through a browser shows the application is up and functioning correctly.

How should the send string be modified to correct this issue?

A. GET /\r\n\r\n

B. GET / HTTP/1.0\r\n\r\n

C. GET /\r\nHost: \r\n\r\n

D. GET /\r\nHTTP/1.0\r\n\r\n
