[Security, Automation, and Policy Integration in Design] To protect against future perimeter breaches, which two design options can help? (Choose two)

• A. Segmentation
• B. Domain fencing
• C. Virtualization
• D. Microperimeters
• E. Microzoning

Answer: A,D

Explanation:
#Explanation:
* B: Segmentation isolates network zones (e.g., separating finance from guest access), limiting lateral movement after a breach.
* E: Microperimeters apply security controls closer to the application or workload, providing granular control and defense in depth.
Other options:
* A: Microzoning is not a widely defined or standard practice in network security.
* C: Domain fencing is not a standard security term or methodology.
* D: Virtualization is a technology, not a security architecture.

NEW QUESTION # 199
Which two statements about MLD snooping are true? (Choose two)

• A. When multiple MLD snooping queriers are enabled in a VLAN, the querier with the lowest IP address in the VLAN is elected as the active MLD snooping querier
• B. An MLD snooping querier election occurs when any MLD snooping querier goes down or if there is an IP address change on the active querier
• C. A VLAN can support multiple active MLD snooping queriers, as long as each one is associated to a different multicast group
• D. When MLD snooping is enabled, QoS is automatically enabled

Answer: A,B

Explanation:
MLD (Multicast Listener Discovery) snooping for IPv6 operates similarly to IGMP snooping in IPv4. It tracks listener reports to restrict multicast flooding within a Layer 2 domain.
* C: Querier elections are triggered when a querier becomes unreachable or its IP address changes.
* D: The querier with the lowest IPv6 address is elected as the active querier, which manages report
/query communication.
Other options:
* A: QoS is not automatically enabled with MLD snooping.
* B: MLD querier functionality operates per VLAN-not per group-so only one querier is elected per VLAN.

NEW QUESTION # 205
In a redundant hub and spoke "wheel" design, all spokes are connected to the hub, and spokes are connected to other spokes as well. During failure on one spoke link, the traffic from that site can be sent to a neighboring site for it to be forwarded to the hub site. But during peak hours, a link is overloaded and traffic is re-routed to a neighbor, which subsequently becomes overloaded. This overload results in network traffic oscillation as the load varies at each spoke site. This design provides more redundancy but not more resiliency because the routing protocol must process many alternate paths to determine the lowest cost path. Which two design changes help to improve resilience in this case? (Choose two.)

• A. Increase routing protocol convergence timers.
• B. Eliminate links between every spoke.
• C. Increase unequal-cost parallel paths.
• D. Increase the number of redundant paths considered during the routing convergence calculation.
• E. Use two links to each remote site instead of one.

Answer: C,E

NEW QUESTION # 206
Refer to the exhibit.

• A. The transit_delay=5 and dpdu_delay=20 are recommended values, considering helto_timer=2 and specified
• B. Only the maximum_transmission_halt_delay and diameter parameters are configurable parameters in 802. to speed up STP convergence process
• C. Only the transit_delay and bpdu_delay timers are configurable parameters in 802.1d to speed up STP convergence process.
• D. The max_age and forward delay parameters can be adjusted to speed up STP convergence process.

Answer: D

NEW QUESTION # 207
Refer to the exhibit.

An engineer has been asked to redesign the traffic flow toward AS 111 coming from AS 500.Traffic destined to AS 111 network 91 7 0.0/16 should come in via AS 100. while traffic destined to all other networks in AS 111 should continue to use the existing path Which BGP attributes are best suited to control this inbound traffic coming from BGP AS 500 Into the 91.7.0.0/16 network?

• A. Use extended community for the 91.7.0.0/16 network, not advertising it to the bi-lateral peer.
• B. Prepend AS path for the 91.7.0.0/16 network and set it for neighbor in AS 200.
• C. Set higher MED for neighbor in AS 100 to influence incoming traffic for the 91. 7.0.0/16 network.
• D. Use local preference on R1 for the networks that AS 500 advertises to AS 111.

Answer: B
