F5 BIG-IP Administration Data Plane Concepts (F5CAB2) 認定 F5CAB2 試験問題 (Q14-Q19):

質問 # 14
A standard virtual server has been associated with a pool with multiple members. Assuming all other settings are left at their defaults, which statement is always true concerning traffic processed by the virtual server?

正解：C


質問 # 15
Refer to the exhibit above.




A BIG-IP pool is configured with Priority Group Activation = Less than 2 available members. The pool members have different priority groups and availability states. Which pool members are receiving traffic?
(Choose one answer)

正解：D

解説：
This question tests understanding of Priority Group Activation (PGA) and how BIG-IP determines which pool members are eligible to receive traffic.
Key BIG-IP Priority Group Concepts:
* Higher priority group numbers = higher priority
* BIG-IP will only send traffic to the highest priority group that meets the Priority Group Activation condition
* Lower priority groups are activated only when the condition is met
* Only available (green) members count toward the activation threshold
Configuration from the Exhibit:
* Priority Group Activation: Less than 2 available members
* Pool Members and Status:
Pool Member
Priority Group
Status
serv1
2
Active (available)
serv2
2
Inactive (down)
serv3
1
Active (available)
serv4
1
Active (available)
Step-by-Step Traffic Decision:
* BIG-IP first evaluates the highest priority group (Priority Group 2)
* Priority Group 2 has:
* serv1 # available
* serv2 # unavailable
* Total available members = 1
* Activation rule is Less than 2 available members
* Condition is true (1 < 2)
* BIG-IP activates the next lower priority group (Priority Group 1)
* Traffic is now sent to:
* serv1 (Priority Group 2)
* serv3 and serv4 (Priority Group 1)
Final Result:
Traffic is distributed to serv1, serv3, and serv4
Why the Other Options Are Incorrect:
* A - Ignores activation of the lower priority group
* B - serv4 is also active and eligible
* C - serv2 is down and cannot receive traffic
Key Data Plane Concept Reinforced:
Priority Group Activation controls when lower-priority pool members are allowed to receive traffic, based strictly on the number of available members in the higher-priority group. In this case, the failure of one high-priority member caused BIG-IP to expand traffic distribution to lower-priority members to maintain availability.


質問 # 16
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：
Comprehensive and Detailed Explanation From BIG-IP Administration Data Plane Concepts documents:
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 # 17
The BIG-IP Administrator wants to provide quick failover between the F5 LTM devices that are configured as an HA pair with a single Self IP using the MAC Masquerade feature. The administrator configures MAC masquerade for traffic-group-1 using the following command:
`tmsh modify /cm traffic-group traffic-group-1 mac 02:12:34:56:00:00`
However, the Network Operations team identifies an issue with using the same MAC address across multiple VLANs. As a result, the administrator enables Per-VLAN MAC Masquerade to ensure a unique MAC address per VLAN by running:
`tmsh modify /sys db tm.macmasqaddr_per_vlan value true`
What would be the resulting MAC address on a tagged VLAN with ID 1501? (Choose one answer)

正解：A

解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Data Plane Concepts documents:
In BIG-IP high availability (HA) configurations, MAC Masquerade is used to speed up failover by allowing traffic-group-associated Self IPs to retain the same MAC address when moving between devices. This prevents upstream switches and routers from having to relearn ARP entries during a failover event, resulting in near-instant traffic recovery.
By default, MAC masquerade applies one MAC address per traffic group, regardless of how many VLANs the traffic group spans. This can create problems in some network designs because the same MAC address appearing on multiple VLANs may violate network policies or confuse switching infrastructure.
To address this, BIG-IP provides Per-VLAN MAC Masquerade, enabled by the database variable:
`tm.macmasqaddr_per_vlan = true`
When this feature is enabled:
BIG-IP derives a unique MAC address per VLAN
The base MAC address configured on the traffic group remains the first four octets The last two octets are replaced with the VLAN ID expressed in hexadecimal The VLAN ID is encoded in network byte order (high byte first, low byte second)
### VLAN ID Conversion:
VLAN ID: 1501 (decimal)
Convert to hexadecimal:
1501₁₀ = 0x05DD
High byte: 05
Low byte: DD
### Resulting MAC Address:
Base MAC: `02:12:34:56:00:00`
Per-VLAN substitution → last two bytes = `05:DD`
Final MAC address:
`02:12:34:56:05:dd`
### Why the Other Options Are Incorrect:
A (01:15) - Incorrect hexadecimal conversion of 1501
B (dd:05) - Byte order reversed (little-endian, not used by BIG-IP)
D (15:01) - Uses decimal values instead of hexadecimal
### Key BIG-IP HA Concept Reinforced:
Per-VLAN MAC Masquerade ensures Layer 2 uniqueness per VLAN while preserving the fast failover benefits of traffic groups, making it the recommended best practice in multi-VLAN HA deployments.


質問 # 18
A BIG-IP system receives a client connection destined to 1.0.0.10:8080. Multiple virtual servers are configured on the system. Which virtual server will process the connection? (Choose one answer)

正解：D

解説：
BIG-IP uses a virtual server matching and precedence algorithm to determine which virtual server processes an incoming connection. This decision is made entirely in the data plane and is based on how specifically a virtual server matches the destination IP address and port.
BIG-IP Virtual Server Selection Rules (Simplified):
When multiple virtual servers could match a packet, BIG-IP selects the most specific match, using the following precedence:
* Exact IP address and exact port
* Exact IP address with wildcard port (port 0 / any)
* Wildcard IP address with exact port
* Wildcard IP address and wildcard port
Applying the Rules to This Scenario:
Incoming traffic destination: 1.0.0.10:8080
* Option C: 1.0.0.10:8080
* Exact IP match
* Exact port match
* Highest possible specificity
* If the virtual server is available (green), it wins the match
* Option B: 1.0.0.10:any
* Exact IP match, but wildcard port
* Lower priority than an exact IP + exact port match
* Option D: 0.0.0.0:8080
* Wildcard IP, exact port
* Lower priority than an exact IP match
* Option A: 0.0.0.0:any
* Wildcard IP and wildcard port
* Lowest priority, used only if no more specific virtual server exists
Final Determination:
Because a virtual server configured with destination 1.0.0.10:8080 exactly matches both the IP address and port of the incoming connection-and is available-it will always be selected to process the traffic.
Key Data Plane Concept Reinforced:
BIG-IP always processes traffic using the most specific matching virtual server. Exact destination IP and port matches take precedence over any wildcard or forwarding virtual server definitions.
