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?

A. create a 0 port virtual server and have it answer for all protocols

B. create a 0.0.0.0:0 virtual server thus eliminating all virtual servers

C. create a transparent virtual server thus eliminating all virtual servers

D. create a wildcard certificate and use it on all *.example.com virtual servers

An LTM device is serving an FTP virtual server that has three pool members. The FTP pool members are monitored via TCP port 21. Customers are reporting that they are able to log in, but are sometimes unable to upload files to the server. Which monitor should the LTM Specialist configure to verify that the servers can handle file uploads?

A. FTP

B. Inband

C. External

D. Scripted

E. Real Server

An LTM Specialist is creating a custom EAV monitor.

In which directory should the LTM Specialist upload the script?

A. /usr/monitor

B. /usr/monitors

C. /config/monitors

D. /usr/bin/monitors

E. /config/templates

What does the following iRule do?

when CLIENT_ACCEPTED { if { [matchclass [IP::client_addr] equals WebClient1-Whitelist1] }{ #log local0. "Valid client IP: [IP::client_addr] - forwarding traffic" #Pool WebClient1

} else { log local0. "Invalid client IP: [IP::client_addr] - discarding" discard } }

A. The iRule compares a client IP to a list. If the client IP is on the list, discard and log the discard.

B. The iRule compares a client IP to a list. If the client IP is NOT on the list, discard and log the discard.

C. The iRule compares a client IP to a list. If the client IP is on the list, the client is sent to Pool WebClient1. Otherwise, discard and log the discard.

D. The iRule compares a client IP to a list. If the client IP is NOT on the list, the client is sent to Pool WebClient1. Otherwise, discard and log the discard.

What do the following iRule commands do when they are used in the same iRule?

set hsl [HSL::open -proto UDP -pool syslog_server_pool]

HSL::send $hsl "<190> [HTTP::host] from [whereis [IP::client_addr] country continent state city zip] , IP: [IP::client_addr]"

A. The commands set up a high-speed logging connection and then send the geographical database to the server.

B. The commands set up a high-speed logging connection and then send the host header and client geographical detail to the connection.

C. The commands set up a high-speed logging connection and then send the host header, HTTP payload, and client geographical detail to the connection.

D. The commands set up a high-speed logging connection to the LTM device and then send the host header and client geographical detail to the connection.

Given the log entry:

011f0005:3: HTTP header (32800) exceeded maximum allowed size of 32768 (Client sidE. vip=/Common/VS_web profile=http pool=/Common/POOL_web client_ip=10.0.0.1)

Which HTTP profile setting can be modified temporarily to resolve the issue?

A. Increase Maximum Requests

B. Decrease Maximum Requests

C. Increase Maximum Header Count

D. Decrease Maximum Header Count

E. Increase Maximum Header size

F. Decrease Maximum Header size

An LTM device is used to load balance web content over a secure channel.

The developers of the web content have done a trace using an HTTP profiler application. They believe that allowing the LTM device to compress traffic to the client will improve performance. The client can utilize GZIP or deflate compression

algorithms.

An LTM Specialist must implement the compression.

The LTM Specialist has completed the following actions:

1.

Create the relevant profile.

2.

Apply the relevant profile to the virtual server (VS).

After applying the relevant profile, the LTM device is failing to compress the traffic. Instead, the traffic is being served with an error.

What is the problem?

A. The incorrect compression algorithm is applied to the compression profile.

B. The LTM device CANNOT SSL offload the traffic in order to read and compress it.

C. The Protocol Profile (Client) option of "Allow Compression" needs to be enabled.

D. The Protocol Profile (Server) option of "Allow Compression" needs to be enabled.

A server administrator notices that one server is intermittently NOT being sent any HTTP requests. The server logs display no issues. The LTM Specialist notices log entries stating the node (172.16.20.1) status cycling between down and up.

The pool associated with the virtual server (10.10.1.100) has a custom HTTP monitor applied. Which tcpdump filter will help trace the monitor?

A. tcpdump -i internal port 80 and host 172.16.1.31

B. tcpdump -i external port 80 and host 10.10.1.100

C. tcpdump -i internal port 80 and host 172.16.1.33

D. tcpdump -i external port 80 and host 172.16.20.1

Based on the output of the tmsh interface show command, what is the issue?

A. There is a duplex mismatch on the management interface.

B. Interfaces 2.1 and 2.2 are defective and need replacement.

C. Flow Control is NOT configured on the management interface.

D. There are too many drops on inbound traffic on interface 1.1.

-- Exhibit

-- Exhibit -Refer to the exhibits. A virtual server has been configured for SSL offload on a single-arm network. On average, the virtual server will be handling 100,000 connections, with a peak of 130,000 connections. Between the virtual server and the web servers there is a

single reverse proxy to provide site caching. The proxy is configured to perform source IP persistence before contacting the web servers. The site is logging users out immediately after logging them in. What should the LTM Specialist do to resolve this issue?

A. Add a source address persistence profile to the virtual server.

B. Create an iRule to add client IP persistence to a SNAT pool member.

C. Change the virtual server server-side TCP profile to tcp-lan-optimized.

D. Configure the virtual server HTTP profile to insert an X-Forwarded-For header.
