Question 16

Which file should the BIG-IP Administrator check to determine when a Virtual Server changed its status from RED to GREEN?

Correct Answer: B
Status changes for local traffic objects (Virtual Servers, Pools, Nodes) are recorded in the Local Traffic Manager (LTM) log.
Health State Logging: When a health monitor marks a resource as available (Green) or unavailable (Red), the system generates a log message in /var/log/ltm.
Log Entry Example: A transition from Red to Green will appear as a message similar to: 01010027:3: Pool /Common/my_pool member /Common/10.0.0.1:80 monitor status up.
Evaluation of Other Options:
/var/log/audit (Option A) logs who changed a configuration, not automated state changes from health monitors.
/var/log/lastlog (Option C) is a standard Linux file that tracks the last login time of users.
/var/log/monitors (Option D) is not a standard log file on the BIG-IP system.

Question 17

Which two methods should the BIG-IP Administrator troubleshoot a Pool-member that's been marked "DOWN" by its Health Monitor? (Pick the 2 correct responses below)

Correct Answer: A,C
When a health monitor marks a member "Down," the goal is to determine if the issue is at the network level or the application level.
Monitor Logging (Option A): In the Pool Member configuration, an administrator can enable "Monitor Logging". This generates a detailed text file in /var/log/monitors/ that shows the exact "Send" string sent by the BIG-IP and the exact "Receive" string (or lack thereof) returned by the server.
TCPdump (Option C): This is the most definitive way to see if the monitor traffic is even leaving the BIG-IP and if the server is responding with a TCP RST (reset) or an ICMP unreachable message. A command such as tcpdump -ni <vlan> host <member_ip> and port <member_port> is standard for this task.
Why not others? While the routing table (Option B) is useful for general connectivity, if other members in the same subnet are "Up," the routing is likely fine. Statistics (Option D) show that it is down but rarely why it is down at a protocol level.
insert code

Question 18

A BIG-IP Administrator adds new Pool Members into an existing, highly utilized pool. Soon after, there are reports that the application is failing to load for some users. What pool level setting should the BIG-IP Administrator check?

Correct Answer: A
When adding new members to an active, high-traffic pool, the Slow Ramp Time setting is critical for maintaining application stability.
* Mechanism: The Slow Ramp Time feature (located in the Pool properties) allows the BIG-IP system to gradually increase the number of connection requests sent to a newly added or recently enabled pool member.
* The Issue: In a highly utilized pool, if Slow Ramp Time is set to 0 (the default), the BIG-IP immediately begins sending a proportional share of traffic to the new members. If the application requires a "warm-up" period (e.g., to build local caches or establish database connection pools), the sudden influx of traffic can overwhelm the new server, causing it to drop requests or fail to load content for users.
* Recommendation: F5 recommends setting a non-zero Slow Ramp Time (measured in seconds) to allow the new member to scale up its processing capacity incrementally.

Question 19

Which two methods should the BIG-IP Administrator troubleshoot a Pool-member that's been marked
"DOWN" by its Health Monitor? (Pick the 2 correct responses below)

Correct Answer: A,C
When a health monitor marks a member "Down," the goal is to determine if the issue is at the network level or the application level.
* Monitor Logging (Option A): In the Pool Member configuration, an administrator can enable
"Monitor Logging". This generates a detailed text file in /var/log/monitors/ that shows the exact "Send" string sent by the BIG-IP and the exact "Receive" string (or lack thereof) returned by the server.
* TCPdump (Option C): This is the most definitive way to see if the monitor traffic is even leaving the BIG-IP and if the server is responding with a TCP RST (reset) or an ICMP unreachable message. A command such as tcpdump -ni <vlan> host <member_ip> and port <member_port> is standard for this task.
* Why not others? While the routing table (Option B) is useful for general connectivity, if other members in the same subnet are "Up," the routing is likely fine. Statistics (Option D) show that it is down but rarely why it is down at a protocol level.

Question 20

Clients report that they cannot reach the virtual server vs-production on port 80, but are able to ping the virtual server address. The configuration is shown below:
Plaintext
ltm virtual vs-production {
destination 10.99.20.50:http
ip-protocol tcp
mask 255.255.255.255
profiles {
http {}
tcp {}
}
source 192.168.0.0/16
translate-address enabled
translate-port enabled
vlans {
external
}
vlans-enabled
}
What is the cause?

Correct Answer: D
The issue is caused by the Source Address restriction configured on the virtual server.
* Source Filter: The configuration contains the line source 192.168.0.0/16. This acts as an implicit Access Control List (ACL). The virtual server will only accept and process TCP connections if the client's source IP address falls within the 192.168.x.x range.
* Why Ping Works: ICMP (Ping) is handled by the Virtual Address object, not the Virtual Server object. Unless ICMP is specifically disabled on the Virtual Address, it will respond to pings from any subnet, even if the Virtual Server itself is restricted by a source filter or is even disabled.
* Evaluation of Other Options:
* Disabled (Option A): If the VS were disabled, the configuration would typically show disabled or state down, and the symptoms would be similar, but the source filter is a more specific
"misconfiguration" in this context.
* Port 80 (Option C): The configuration destination 10.99.20.50:http explicitly confirms it is listening on port 80.
* Unallowed Subnet: If a client from a different network (e.g., 10.10.1.5) tries to connect, the BIG- IP will silently drop the connection or send a reset because it does not match the defined source criteria.
