A network engineer is designing an ASA cluster for a data center. The cluster will connect to two upstream switches, and each ASA will have two physical interfaces in the same VLAN. The engineer wants to maximize throughput and avoid a single point of failure on the switch links. Which deployment model should be used?

Individual (non-cluster) interfaces

Spanned (individual interfaces)

Active/Standby failover with EtherChannel

An engineer is configuring dual-hub DMVPN with BGP. Spokes are configured with two BGP peers (one for each hub). The engineer wants to ensure that if the primary hub fails, the spoke will use the secondary hub for all traffic. What configuration is needed?

Set a higher local preference for the primary hub

Use static routes to the primary hub with a lower administrative distance

Configure the secondary hub with a higher weight

Set a lower MED for the primary hub

An administrator is configuring a new ASA cluster. They have set up the control link and data interfaces. However, they notice that cluster members are not synchronizing connection state information. What is the most likely cause?

The cluster members have different software versions

The data interfaces are not in the same VLAN

The control link is not configured as a dedicated interface

A security team is deploying an ASA cluster for remote-access VPN. They want to ensure that if a cluster member fails, all active VPN sessions are seamlessly transferred to other members without re-authentication. Which feature of ASA clustering enables this?

Stateful failover of VPN sessions

VPN load balancing (VLB) with sticky connections

Round-robin DNS for VPN gateway

Active/Standby failover with replication

A multinational company is deploying DMVPN for its branch offices. They need redundancy so that if one hub fails, branches can still reach the corporate network. They also want to distribute traffic between two hubs to avoid overloading a single hub. Which topology should they implement?

Spoke-to-spoke DMVPN without hubs

Single-hub DMVPN with a backup hub

Full mesh of IPsec tunnels between all sites

Part of the 2.0 Secure Connectivity and Segmentation domain, which accounts for 20% of the CCIE-SECURITY exam. Cisco does not publish an official question count, but from its 120-minute exam (~50–80 total, ~10–16 in this domain), expect 2–3 from this objective — we provide 54 practice questions to prepare you well beyond it.
