Configure VLAN, Configure Config-Sync IP. Configure Self-IPs. Configure Failover type. Establish Device Trust, Create Device Group

Q253. An HA pair of LTM devices configured in Active-Standby mode stops responding to traffic and causes an outage. The Active device becomes Standby, but the partner device stays in Standby mode instead of taking over as Active. A reboot and restart of the services brings the LTM device to Active mode for a short time, but then it goes into Standby mode again.

A connection rate limit to the Virtual Server

A connection limit to the Virtual Server

A OneConnect profile to the Virtual Server

Q255. A new web application is being deployed Mutual SSL authentication must be used to authenticate clients.
Which of the following two tasks must be completed to meet therequirements? (Choose two)

configure the client SSL profile with the Trusted .Certificate Authorities

Q256. — Exhibit –

— Exhibit —
Refer to the exhibit.
An LTM Specialist configures a virtual server that balances HTTP connections to a pool of three application servers. Approximately one out of every three connections to the virtual server fails.
Which two actions will resolve the problem? (Choose two.)

Assign a custom HTTP monitor to the pool.

Enable SNAT automap on the virtual server.

Verify that port lockdown is set to allow port 80.

Verify the default gateway on the application servers.

Increase the TCP timeout value in the default TCP profile.

Q257. The end users of a web application need to verify that their browsers received the complete message-body from the web server.
Which HTTP header will accomplish this?

Range

Expect

Accept-Ranges

Q258. Refer to the exhibit.

Which Pool Members are receiving traffic?

Serv1, serv2,serv3, serv4

serv1, serv3

serv1, serv3, serv4

serv1

Q259. An LTM device an application that requires all connections to be secured via SSL The device must verify that request contain a specific cookie before allowing the request to be sent to the pool member.
Which virtual server type should an LTM Specialist configure on the LTM device?

The iRule execution will continue with the next statement.

The execution of the current event within the iRule will be terminated.

The iRule execution will be terminated, and both the client and server side connections will be reset.

The connection will continue, but the iRule will NOT be executed again for the lifetime of the connection.

Q261. 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.)

Q262. An LTM Specialist reports that an application si no longer reachable after it has beenupgraded.
Nothing has been changed in the configuration on the LTM device.
The logs indicates that health monitors to all servers have failed as shown:
What should the LTM Specialist verify next?

That the TCP hand shake with the servers is stall completed using tcpdump

That the custom receive string for the HTTP monitor has changed with the upgrade

That the can still ping the servers from te BIG_ IP device.

That the firewall between the BIG-ip device and servers is still allowing HTTP

Explanation
The log shows that tcp detection is normal, but http detection is abnormal. So we should pay attention to the detection problem of http level
