F5 BIG-IP ASM Specialist 認定 303 試験問題:

1. DNS queries from two internal DNS servers are being load balanced to external DNS Servers via a Virtual Server on a BIG-P device. The DNS queries originate from 192.168.101.100 and 192.168.101.200 and target 192.168.21.50 All DNS queries destined for the external DNS Servers fail Which property change should the BIG-IP Administrator make in the Virtual Server to resolve this issue?

A) Type to Performance (HTTP)
B) Protocol Profile (Client) to DNS-OPTIMZED
C) Source Address to 192.168.101.0/24
D) Protocol to UDP

2. -- Exhibit -

-- Exhibit --
Refer to the exhibit.
An LTM Specialist configures a virtual server to perform client-side encryption while allowing the server-side traffic to be unencrypted. Application owners report that images are failing to load through the virtual server; however, images load when going directly to the server.
What is the problem with the images loading through the virtual server?

A) Image references are for HTTP objects, not HTTPS.
B) The virtual server does not have "SSL Offloading" enabled.
C) The virtual server does not have an HTTP profile associated.
D) Image references are for HTTPS objects, not HTTP.

3. -- Exhibit -

-- Exhibit --
Refer to the exhibit.
A user is unable to access an application.
What is the root cause of the problem?

A) The 'Content-Length' is zero.
B) The user failed authentication.
C) The GET request uses the wrong syntax.
D) The User-Agent is incorrect.

4. An application is being load balanced through the LTM device using the configuration displayed below.
The network has been re-engineered to NAT all client connection. As a result, allclient connections are hitting the same pool member.

Which changes should the LTM Specialist make in order to restore load balancing functionality wile maintaining session persistence?

A) Change the virtual serer type to Forwarding (Layer 4) and leave the persistence type tohash source Address
B) Leave the virtual server type set Performance (Layer 4) and change the persistence type to hash
C) Change the virtual server to Standard add an http profile, and change the persistence profile to Cookie persistence
D) Change the virtual server type to Standard, add an httpprofile, and change the persistence profile to Destination Address

5. An LTM Specialist must perform a packet capture on a virtual server with an applied standard FastL4 profile.
The virtual server 10.0.0.1:443 resides on vlan301.
Which steps should the LTM Specialist take to capture the data payload successfully while ensuring no other virtual servers are affected?

A) The LTM device is under light load. The traffic should be mirrored to a dedicated sniffing device. On the sniffing device, the packet capture tcpdump -ni vlan301 should be executed.
B) The standard FastL4 profile should have PVA acceleration disabled. Then the packet capture tcpdump
-ni vlan301 should be executed on the command line interface.
C) A new FastL4 profile should be created and applied to the virtual server with PVA acceleration disabled.
Then the packet capture tcpdump -ni vlan301 should be executed on the command line interface.
D) The packet capture tcpdump -ni vlan301 should be executed on the command line interface. There is no need to change profiles or PVA acceleration.
