two Stream profiles and an iRule with the command of STREAM expression (@http:// @https:// @@internalapp@publicapp@)

one Stream profile with the expression of @http:// @https:// @

Which two server type should be used? (Choose two.)

Standard

Internal

Performance HTTP

Forwarding IP

Stateless

NO.59 A Client makes the request displayed below to the application server.

NO.60 Refer to the exhibit.

The http monitor is applied to a pool. All members are enabled. One server responds as follows.

What is the resulting status of this poo! member?

Offline (Disabled)

Offline (Enabled)

Unavailable (Disabled)

Available (Enabled)

The first picture “Send String” and “Receive String” are not clear. Send String should be “GOOD”, the response packet does not contain this keyword. Receive Disable String is completely unclear. If the response packet contains the content of Receive Disable String at this time, it will be Available (Disabled), If the content of Receive Disable String is not included, then Offline (Enabled).

What is the correct order of steps to meet this requirement?

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

Clientssll, Stream

Serverless, Stream

Clientssl, fastL4, Stream

Serverless, fastL4, Stream

For http application and external encryption, clientssl is required, and if the message content needs to be modified, the steam profile is required. FastL4 profile cannot coexist with clientssl and stream.

NO.63 Where does a LTM Specialist view all of the objects that are part of a deployed iApp?

iAPP> Application Policy > Objects

Local Traffic . Virtual Servers > Applications

Certain content must be manipulated by the following IRule:

Which set of profiles must be applied to the virtual server?

TCP, HTTP server SSL Stream

TCP, HTTP, Client SSL, Stream

TCP, HTTP, OnceConnect, Stream

Fast L4, HTTP server SSL Stream

Client encryption is required , clientssl, irule contains HTTP events and stream execution, http profile stream profile.

NO.65 Exhibit.

An LTM Specialist needs to configure VS^HTTP and VS_DB for an online shopping site. The VS HTTP passes the client requests to the webservers. The webservers query the database servers through the VS_DB. Initially, the LTM Specialist finds the database servers directly return the packets to the webservers.
which setting must be enabled for the configuration to function correctly?

VS_HTTP snat auto map

VS.HTTP auto last hop

VS DB auto last hop

VS_DB snat auto map

NO.66 Remote office users are having performance issues with a virtual hosted on the F5 LTM. The LTM Specialist reviews the configuration for the virtual server and determine that some settings are set with default profiles.
Which profile should the LTM Specialist enable to improve virtual server performance?

A WAN optimized client side profile

A FastL4 profile on the virtual server

An HTTP profile for the virtual server

A Stream profile for the remote user networks

They key word is that there are performance problem with Remote office users, no F5. The user experience can be improved through tcp optimization. The expression should be wom-tcp-wan-optimized in Protocol Profile (Client)

NO.67 An LTM Specialist needs to force only FTP traffic, sourced from subnet 10.10.10.0/24 to virtual server 10.10.20.1 to the new FTP1 server. The following virtual servers are configured on the LTM device:
Traffic sourced from 10.10.10/24 must use the specific pool member for load balancing.
Which configuration change is needed to meet the requirements?

Create a new virtual server for traffic sourced from 10.10.10.0/24 on port 80 that is destined to 10.10.20.1/32, and create a new pool has only the pool member FTP1 defined.

Add FTP1 to the pool assigned to the MyVS4 virtual server, and remove all other pool members from the pool.

Create a new virtual server for traffic sourced from 10.10.10.0/24 on traffic sourced from 10.10.10./24 on port 21 that is destined to 10.10.20.1/32, and create a new pool that has only the pool member FTP1 defined.

Add FTP1 to the pool assigned to the MyVS2 virtual server, and remove all other pool member from the pool.

According to the VS matching order, first match the destination host IP, then match the destination port and finally match the source network segment. In the current network configuration, 10.10.10./24 access to 10.10.10.20.1 will hit MyVS2. If there is no error in the title, subnet 10.10.10.0 to virtual Server 10.10.20.1 to the FTP1 server,” Is to distribute all traffic from 10.10.10.1 to FTP1, then D That’s right.

NO.68 An application is sensitive to packet loss and unexpected session termination. A pair of LTM devices is configured in an Active/Standby high availability configuration. SNATS are NOT used and the virtual server contains a Universal Persistence profile.
which two actions must an LTM Specialist take to ensure the sessions are maintained between the client and server during an LTM device failover event while maintaining maximum uptime? (Choose two.)

configure a serial failover cable for mirror traffic

configure a OneConnect profile to mirror connections

configure a VLAN and primary mirroring address for mirror traffic

enable Mirroring for a virtual server and persistence profile

enable Clone Pools for a virtual server and a persistence profile

NO.69 A custom TCP application using a single server is being migrated to the LTM device. A server is being added to the pool. The application is known to violate the TCP protocol RFC. The application currently works without error from a user perspective.
Which virtual server type is appropriate in this situation?

Stateless TCP protocol is not applicable

Performance (Layer 4)-pure layer A forwarding

forwarding (Layer 2) pure routing forwarding, pool cannot be specified

Standard-tcp profile exists, RFC verification will be performed

NO.70 A pool has four members. Ail of the servers have been designed and configured with the same application. Each client’s request can significantly the performance of the servers.
Which load balancing method should the LTM Specialist use to maintain a relatively even load across all servers?

Least Connections

Priority Group

Ratio

Observed

NO.71 An application is expected to maintain more than 100,000 concurrent TCP connections to a single pool member.
What is an appropriate SNAT configuration in this situation?

A SNAT pool with 4 IP addresses

SNAT automap enabled

A static SNAT

A SNAT pool with IP address
Explanation
One IP can establish 65,535 connections only the number of snapit’s IP exceeds 100,000. AT least two snaptips are required. Options B, C, and all have only IP, which is obviously not enough

NO.72 A company plans to launch a huge marketing campaign and expects increase demand of their secure website. With the current virtual server setup, the LTM Specialist expects that the LTM device will reach its capacity limits. For the wen application to function properly. Cookies persistence is required. The LTM Specialist needs to reduce LTM device load without breaking the application.
Which two settings should the LTM Specialist modify to meet the requirement? (Choose two.)

Remove HTTP compression profile

Remove HTTP profile

Remove web acceleration profile.

Modify virtual Server type to performance (Layer 4)

Remove ClientSSL profile

It is required that cookie persist must be used and http profile must be used, and SSL offloading must also be required. It must be in standard mode, excluding BD E.

NO.73 An LTM Specialist needs to upgrade all guests on a Viprion eight CMP guests.
What is the maximum number of guests that the LTM Specialist should upgrade at once?

Eight

One

TWO

Four
Explanation
Each guest is independent, just like hardware upgrades. Can only upgrade one by one, there is no way to upgrade at the same time.

NO.74 An LTM device provides load balancing to a web application? The LTM device has two dual-core processors and a licensed SSL Transactions Per Second (TPS) limit of 500 CMP is enabled.
TLS connections are used between client systems and virtual servers on the LTM device, as well as from the LTM device to servers used as part of LTM pool.
TLS enabled virtual servers utilize certificates based on 2048-bit keys During a peak period. 2560 new TLS transactions per second are attempted to the web application via the LTM device.
What will happen in this scenario?

560 new TLS transactions will be silently discarded due to the SSL TPS license limit

Nothing: TLS transactions per second are NOT affected by an SSL TPS license limit

2060 new TLS transactions will be silently discarded due to the SSL TPS license limit

Nothing: 2560 TLS transactions per second is within the SSI TPS license limit.
