Question 6 of 209

Users are experiencing low throughput when downloading large files over a high-speed WAN connection. Extensive packet loss was found to be an issue but

CANNOT be eliminated.

Which two TCP profile settings should be modified to compensate for the packet loss in the network? (Choose two.)

Answer

Suggested Answer

The suggested answer is C, D.

To compensate for packet loss in a network when users are experiencing low throughput over a high-speed WAN connection, modifying TCP profile settings related to proxy buffering can help. The 'proxy buffer low' and 'proxy buffer high' settings are specifically designed to manage the accumulation of data when there is packet loss or slow acknowledgments. Adjusting these settings ensures that the TCP profile can handle the increased load and buffering requirements, thus improving throughput in such conditions.

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?

Answer

Suggested Answer

The suggested answer is D.

To reduce the number of objects on the LTM device, the LTM Specialist should create a wildcard certificate and use it on all *.example.com virtual servers. This approach allows a single certificate to cover multiple subdomains, eliminating the need to store multiple certificates for each virtual server, thus reducing the number of objects on the LTM device.

The pool members are serving up simple static web content.

The current virtual server configuration is given as follows: tmsh list ltm virtual simple ltm virtual simple { destination 10.10.10.10:80 ip-protocol tcp mask 255.255.255.255 profiles { http { } httpcompression { } oneconnect { } tcp { } }

snat automapvlans-disabled}

tmsh list ltm pool simple_pool

ltm pool simple_pool {members {10.10.10.11:80 {address 10.10.10.11 }10.10.10.12:80 {address 10.10.10.12 }10.10.10.12:80 {address 10.10.10.13 }}}

Which three objects in the virtual server configuration can be removed without disrupting functionality of the virtual server? (Choose three.)

Answer

Suggested Answer

The suggested answer is A, C, E.

The tcp profile is implied by the use of tcp protocol in the configuration, thus it can be removed because the system will use the default tcp profile. The oneconnect profile is used to reuse TCP connections to backend servers, which is not necessary for simple static web content and can thus be removed without impacting functionality. The httpcompression profile applies HTTP compression, which is not essential for serving static content and can also be removed without disrupting the virtual server's functionality. Therefore, tcp, oneconnect, and httpcompression profiles can be safely removed.

Question 9 of 209

An LTM device is running BIG-IP v10.2.0 software. The LTM Specialist is tasked with upgrading the LTM device to BIG-IP v11.2.0 HF1. The LTM Specialist starts the upgrade process by selecting the uploaded Hotfix and installing to an unused volume. After 10 minutes, the LTM Specialist checks the status of the upgrade process and notices that the process is stalled at 0%.

What should the LTM Specialist verify?

Answer

Suggested Answer

The suggested answer is B.

To upgrade an LTM device to a new software version, the base software version must exist on the device before applying a hotfix. If the base version is not present or if there are multiple versions causing a conflict, the system cannot proceed with the upgrade, resulting in the process stalling at 0%.

Question 10 of 209

A stand-alone LTM device is to be paired with a second LTM device to create an active/standby pair. The current stand-alone LTM device is in production and has several VLANs with floating IP addresses configured. The appropriate device service clustering (DSC) configurations are in place on both LTM devices.

Which two non-specific DSC settings should the LTM Specialist configure on the second LTM device to ensure no errors are reported when attempting to synchronize for the first time? (Choose two.)

Answer

Suggested Answer

The suggested answer is B, D.

To properly configure a second LTM device as part of an active/standby pair without encountering errors during synchronization, it is important to ensure that fundamental network configurations are consistent across both devices. VLANs need to be configured so that the network segments are recognized by both devices. Similarly, self IP addresses must be configured to allow the devices to communicate over the network correctly. Without these configurations, the devices might not synchronize properly, causing potential errors.
