質問 # 18
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 # 19
The network architecture for a BIG-IP consists of an external VLAN and an internal VLAN with two interfaces connected to the upstream switch. The design requires fault tolerance in the case that one of the interfaces is down. Which deployment architecture meets these requirements? (Choose one answer)
正解：D
解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Data Plane Concepts documents:
To meet the requirement of fault tolerance when one interface goes down, BIG-IP must use link aggregation so that loss of a single physical link does not isolate the VLAN(s).
How the objects relate (data plane view)
Interfaces = physical links.
Trunk (LACP) = bundles multiple interfaces into one logical link that provides redundancy (and possibly bandwidth aggregation).
VLANs are assigned to interfaces or trunks. If you need multiple VLANs on the same trunk, they must use 802.1Q tagging (because you can only have one untagged VLAN per interface/trunk).
Self IPs are then placed on the VLANs to provide BIG-IP presence and routing/ARP functions, but self IPs are not what provides link resiliency-the trunk does.
Why Option D is correct
You have two physical interfaces and you want resiliency if one fails → put both interfaces into one trunk with LACP enabled.
You need both external and internal VLANs on those same two links → both VLANs should be configured as tagged on that trunk, so they can coexist on the same aggregated link.
If either physical interface fails, the trunk remains up via the remaining interface, keeping both VLANs operational.
Why the other options are incorrect
A: Two VLANs cannot both be untagged on the same trunk/interface. Only one untagged VLAN is possible; additional VLANs must be tagged.
B: Two trunks "each with one VLAN" would typically mean splitting VLANs across separate trunks. With only two interfaces total, that becomes one interface per trunk-if one interface goes down, the VLAN on that interface is down (no redundancy for that VLAN).
C: Same redundancy problem as B, and disabling LACP removes the negotiated aggregation behavior expected when the switch engineer specifically requested LACP.
質問 # 20
When using the setup utility to configure a redundant pair, you are asked to provide a "Failover Peer IP".
Which address is this?
正解：D
解説：
When establishing a redundant pair, each device must know where to send its health heartbeats and sync data.
* The Peer IP:TheFailover Peer IPis the IP address belonging to theotherBIG-IP device in the HA pair.
This is typically a34Self-IP on a dedicated "HA" or "Internal" VLAN, or the Management IP.
* Purpose:It identifies the destination for the "Heartbeat" (the "Are you alive?" check).
* Setup Context:During the initial setup, you tell Device A to look for Device B at its "Failover Peer IP," and you tell Device B to look for Device A at its respective "Failover Peer IP."
質問 # 21
To increase available bandwidth of an existing Trunk, the BIG-IP Administrator is adding additional interfaces. Which command should the BIG-IP Administrator run from within bash shell?
正解：A
解説：
Configuring networking objects in BIG-IP requires using the correctTMSH module pathandverb.
* Module Path:Trunks are networking objects, so they reside under the /net module, not /sys.
* Verb:Since the trunk already exists, the modify verb must be used to update its properties rather than create.
* Syntax:The correct syntax to append physical interfaces to an existing trunk is tmsh modify /net trunk
[name] interfaces add { [port list] }.
* Data Plane Impact:Adding interfaces to a trunk (Link Aggregation) increases the total aggregate bandwidth available to the system and provides additional hardware redundancy.
質問 # 22
The BIG-IP Administrator needs to ensure that if a pool member is marked down by the monitor, the BIG-IP system sends existing connections to another available pool member. Which task should the BIG-IP Administrator perform to meet this goal?
正解：A
解説：
By default, when a pool member is marked "down" by a monitor, the BIG-IP system stops sendingnew connections to that member, but it typically allows existing connections to time out naturally (or resets them depending on profile settings).
* Action on Service Down:This setting is configured at thePoollevel.
* Reselect:When set toReselect, if a pool member is marked down, the BIG-IP system will immediately attempt to pick a different available pool member for any existing, active connections associated with the failed member.
* Client Experience:This is used to maintain the user session by transparently moving the traffic to a healthy server without the client needing to re-establish the connection to the Virtual Server.
