NEW QUESTION # 51
A BIG-IP Administrator needs to configure health monitors for a pool containing HTTP, HTTPS, FTP, and SSH services.
Which configuration ensures accurate member status?
Answer: A
Explanation:
Using "at least one" ensures each member is marked up based on its relevant service monitor.
NEW QUESTION # 52
Refer to the exhibit.
A BIG-IP Administrator configures a new VLAN on an HA pair of devices that does NOT yet have any traffic. This action causes the assigned traffic group to fail over to the standby device. Which VLAN setting should be changed to prevent this issue?
Answer: A
Explanation:
The exhibit shows the advanced configuration of a VLAN where the Fail-safe option is checked. VLAN Fail- safe is a high-availability feature used to monitor network connectivity on a specific VLAN. When enabled, the BIG-IP system monitors the VLAN for network traffic. If the system does not detect any " useful " traffic on the VLAN within the specified Fail-safe Timeout (which is 90 seconds in the exhibit), it attempts to generate traffic by pinging the default gateway or other devices. If it still detects no traffic, the BIG-IP concludes that the VLAN is unreachable or the network interface has failed, and it triggers a " Fail-safe Action " -in this case, " Reboot " or a failover to the peer device in the HA group.
Because the administrator has just created a new VLAN that " does NOT yet have any traffic, " the Fail-safe mechanism triggers immediately after the 90-second timeout period. Since no devices are yet communicating on this VLAN, the BIG-IP incorrectly assumes there is a hardware or cabling failure and forces a failover to ensure the standby device (which might have better connectivity) takes over. To prevent this unwanted failover, the administrator should uncheck the Fail-safe box for that specific VLAN until the VLAN is fully populated with active nodes and regular traffic. Once the application is live and traffic is flowing, Fail-safe can be re-enabled to provide an additional layer of redundancy. Auto Last Hop (Option A) and Source Check (Option B) are routing and security features that do not trigger HA failover events.
NEW QUESTION # 53
A Standard Virtual Server for a web application is configured with Automap for Source Address Translation.
The original client IP must be known by backend servers.
What should the BIG-IP Administrator configure?
Answer: A
Explanation:
The X-Forwarded-For header preserves the original client IP when SNAT is enabled.
NEW QUESTION # 54
A Standard Virtual Server for a web application is configured with SNAT Automap. The original client IP must be known by backend servers.
What should the BIG-IP Administrator configure?
Answer: B
Explanation:
X-Forwarded-For inserts the original client IP into HTTP headers while SNAT is enabled.
NEW QUESTION # 55
Refer to the exhibit.
DNS queries from two internal DNS servers are being load-balanced to external DNS servers via a virtual server on a BIG-IP device. The DNS queries originate from:
192.168.10.100
192.168.10.200
and target:
192.168.2.150
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?
(Choose one answer)
Answer: C
Explanation:
DNS traffic is primarily transported using UDP port 53. In the exhibit, the Virtual Server is configured with the Protocol set to TCP, which prevents standard DNS queries from being processed correctly. BIG-IP Virtual Servers must be configured with the correct Layer 4 protocol to match the application traffic they are handling.
According to the BIG-IP Administration: Data Plane Configuration documentation:
The Protocol setting on a Virtual Server defines whether traffic is processed as TCP, UDP, or another supported transport protocol.
Standard DNS queries and responses use UDP, while TCP is only required for DNS zone transfers (AXFR) or exceptionally large responses.
When a DNS Virtual Server is incorrectly configured with TCP, UDP-based DNS queries are dropped, causing all requests to fail.
Why the other options are incorrect:
A). Protocol profile (Client) to DNS_OPTIMIZEDA DNS profile enhances DNS functionality but does not correct an incorrect transport protocol configuration.
B). Type to Performance (HTTP)Performance (HTTP) Virtual Servers are designed for HTTP traffic and are not suitable for DNS services.
C). Source Address to 192.168.10.0/24The existing source IPs already fall within the allowed range, so this setting does not address the failure.
Correct Resolution:
Changing the Protocol to UDP aligns the Virtual Server with standard DNS transport requirements, allowing DNS queries to be successfully processed and load-balanced.
