質問 # 48
A BIG-IP Administrator configures remote authentication and needs to ensure that users can still log in even when the remote authentication server is unavailable. Which action should the BIG-IP Administrator take in the remote authentication configuration to meet this requirement? (Choose one answer)
正解：A
解説：
Although remote authentication (LDAP, RADIUS, TACACS+) is a control-plane / management-plane feature, it directly affects availability and resiliency of administrative access, which is a critical operational HA consideration.
How BIG-IP Remote Authentication Works:
* BIG-IP can authenticate administrators against:
* LDAP
* RADIUS
* TACACS+
* When remote authentication is enabled, BIG-IP by default relies on the remote server for user authentication
* If the remote authentication server becomes unreachable, administrators may be locked out unless fallback is configured Why "Fallback to Local" Is Required:
The Fallback to Local option allows BIG-IP to:
* Attempt authentication against the remote authentication server first
* If the remote server is unreachable or unavailable, fall back to:
* Local BIG-IP user accounts (admin, or other locally defined users)
This ensures:
* Continuous administrative access
* Safe recovery during:
* Network outages
* Authentication server failures
* Maintenance windows
This behavior is explicitly recommended as a best practice in BIG-IP administration to avoid loss of management access.
Why the Other Options Are Incorrect:
* A. Configure a second remote user directory
* Provides redundancy only if both directories are reachable
* Does not help if remote authentication as a whole is unavailable
* B. Configure a remote role group
* Maps remote users to BIG-IP roles
* Does not affect authentication availability
* D. Set partition access to "All"
* Controls authorization scope after login
* Has no impact on authentication success
Key Availability Concept Reinforced:
To maintain administrative access resiliency, BIG-IP administrators should always enable Fallback to Local when using remote authentication. This prevents lockouts and ensures access even during authentication infrastructure failures.
質問 # 49
The diagram below shows the TCP connection setup for an application.
Which of the following virtual server types applies? (Choose one answer)
正解：B
解説：
The diagram illustrates a specific TCP handshake sequence where the BIG-IP system acts as a transparent forwarder rather than a full proxy. The key indicators that identify this as a Forwarding (IP) virtual server are as follows:
Initial Packet Processing: The diagram explicitly states that the LTM evaluates the packet looking only at the destination IP address. This is the fundamental characteristic of a Forwarding IP virtual server, which uses the system's routing table to make forwarding decisions instead of load balancing to a pool of members.
Handshake Sequence: Unlike a Standard virtual server, which completes the three-way handshake with the client (SYN, SYN-ACK, ACK) before initiating a separate connection to the server, the Forwarding IP virtual server passes the client's original SYN packet directly to the destination node.
Response Timing: The BIG-IP system waits for the SYN-ACK from the destination node before it sends a SYN-ACK back to the client. It essentially "passes through" the handshake signals while still maintaining a state entry in the connection table to track the flow.
Packet-by-Packet Logic: While it tracks the state, it does not perform address translation (unless SNAT is specifically configured) or deep packet inspection like a full proxy would.
Why other options are incorrect:
Standard virtual server: A Standard virtual server is a "full proxy." It would finish the handshake with the client first and only then open a second, independent TCP connection to the backend server.
Stateless virtual server: A stateless virtual server does not track connections in the connection table. The diagram shows the system meticulously passing sequence numbers ($seq\_num$) and acknowledgment numbers ($ack\_num$) between the two sides, which requires stateful tracking of the TCP flow.

質問 # 51
An ecommerce company is experiencing latency issues with online shops during Black Friday's peak season. The BIG-IP Administrator detects an overall high CPU load on the BIG-IP device and wants to move the top utilized Virtual Servers to a dedicated BIG-IP device. Where should the BIG-IP Administrator determine the problematic Virtual Servers? (Choose one answer)
正解：A
解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Data Plane Concepts documents:
When troubleshooting performance and latency issues on BIG-IP, especially under peak load conditions, it is critical to identify which Virtual Servers are consuming the most resources. This is a core data plane analysis task.
BIG-IP provides multiple views of configuration and status, but only certain areas expose real-time and historical traffic statistics that correlate directly with CPU usage and throughput.
Why Option C Is Correct:
Statistics > Module Statistics > Local Traffic > Virtual Servers provides:
Real-time and cumulative statistics per Virtual Server
Metrics such as:
Bits in / Bits out
Packets in / Packets out
Current connections
Connection rate
Total requests
The ability to identify high-traffic or high-connection Virtual Servers, which are the most likely contributors to elevated CPU utilization These statistics allow the administrator to objectively determine which Virtual Servers are the top consumers of system resources and therefore good candidates for migration to a dedicated BIG-IP device.
Why the Other Options Are Incorrect:
A . Local Traffic > Virtual Servers > Virtual Server List
Primarily a configuration view
Does not provide sufficient performance or utilization statistics to identify CPU-heavy Virtual Servers B . System > Platform Displays hardware-level information such as CPU cores, memory, disk, and platform type Does not break down utilization by Virtual Server D . Local Traffic > Network Map Provides a logical topology view of Virtual Servers, pools, and pool members Useful for understanding relationships, but not for identifying high-utilization Virtual Servers Key Data Plane Concept Reinforced:
To diagnose performance problems and plan traffic redistribution, BIG-IP administrators must rely on Module and object-level statistics, not configuration screens. The Virtual Server statistics view is the authoritative location for identifying traffic hotspots that directly impact CPU and latency during peak events such as Black Friday.
質問 # 52
A BIG-IP Administrator needs to apply a health monitor for a pool of database servers named DB_Pool that uses TCP port 1521. Where should the BIG-IP Administrator apply this monitor?
正解：C
解説：
In the BIG-IP system object hierarchy, health monitors can be applied at three levels: Node, Pool, and Pool Member.
* Pool Level (Properties): Applying a monitor at the Pool > Properties level is the most common and efficient administrative practice. When applied here, the monitor is inherited by all members of that pool. If the monitor fails for a specific member, that member is marked "down" specifically for that pool.
* Node Level: If a monitor is applied at the Node level (Local Traffic > Nodes), it checks the health of the physical IP address itself. If it fails, that node (and all pool members associated with it) is marked down globally across the entire system.
* Member Level: Applying a monitor at the Pool > Members level allows for specific "per-member" monitoring, which is usually only done if different members in the same pool require different health checks.
* The Specific Case: For a standard database pool like DB_Pool, the administrator should navigate to Local Traffic > Pools > DB_Pool > Properties and select the appropriate monitor (e.g., a custom TCP or Oracle monitor) from the "Health Monitors" configuration section.
