A high-availability (HA) pair configuration uses only the hardwire serial cable connection to determine device state. A power outage occurs to the PDU powering the active unit. The standby unit takes over the active role as expected.

How is the peer unit able to determine the active unit is unavailable?

A.

voltage loss on serial cable

B.

no data stream received on serial port

C.

no response on management interface

D.

no heartbeat packets received on self IPs

A virtual server for a set of web services is constructed on an LTM device. The LTM Specialist has created an iRule and applied this iRule to the virtual server:

when HTTP_REQUEST {

switch [HTTP::uri] {

"/ws1/ws.jsp" {

log local0. "[HTTP::uri]-Redirected to JSP Pool"

pool JSP

}

default { log local0. "[HTTP::uri]-Redirected to Non-JSP Pool"

pool NonJSP

}

}

}

However, the iRule is NOT behaving as expected. Below is a snapshot of the log:

/WS1/ws.jsp-Redirected to JSP Pool

/WS1/ws.jsp-Redirected to JSP Pool

/WS1/ws.jsp-Redirected to JSP Pool

/WS1/WS.jsp-Redirected to Non-JSP Pool

/ws1/WS.jsp-Redirected to Non-JSP Pool

/WS1/ws.jsp-Redirected to JSP Pool

/ws1/ws.jsp-Redirected to Non-JSP Pool

What should the LTM Specialist do to resolve this?

A.

Use the followinG.switch -lc [HTTP::uri]

B.

Use the followinG.switch [string tolower [HTTP::uri]]

C.

Set the "Case Sensitivity" option of each member to "None".

D.

Select the "Process Case-Insensitivity" option for the virtual server.
