NEW QUESTION # 544
Most security monitoring systems use a signature-based approach to detect threats. In which two instances are systems based on Network Behavior Anomaly Detection better than signature- based systems when it comes to detecting security threat vectors? (Choose two.)
Answer: C,E
Explanation:
Intrusion threat detection: Network Behavior Anomaly Detection (NBAD) can detect unusual patterns or anomalies in network behavior, making it effective for identifying intrusions that do not match known attack signatures.
New zero-day attacks: NBAD is useful in detecting previously unknown (zero-day) attacks, as it focuses on unusual network behavior rather than relying on known attack signatures, which signature-based systems may miss.
NEW QUESTION # 545
Company XYZ is designing their network using the three-layer hierarchical model. At which layer must the QoS design classify or mark the traffic?
Answer: D
NEW QUESTION # 546
A national retail company is expanding their business by adding several international sites in the next 12 months. With their current IT infrastructure, they face a high number of expenses in managing and maintaining their two current data and voice networks. In addition, the business wants to invest in technologies that offer enhancements to business activities and increase employee productivity. Which two technical requirements should be considered during the network design phase? (Choose two.)
Answer: B,E
NEW QUESTION # 547
Refer to the exhibit.
This network is running EIGRP as the routing protocol and the internal networks are being advertised in EIGRP. Based on the link speeds, all traffic between London and Rome is getting propagated via Barcelona and the direct link between London and Rome is not being utilized under normal working circumstances. The EIGRP design should allow for efficiency in the routing table by minimizing the routes being exchanged. The link between London and Rome should be utilized for specific routes. Which two steps accomplish this task? (Choose two.)
Answer: B,D
NEW QUESTION # 548
Which purpose of a dynamically created tunnel interface on the design of IPv6 multicast services is true?
Answer: C
Explanation:
In the design ofIPv6 multicast services, particularly usingPIM Sparse Mode, thefirst-hop router(which is connected to the multicast source) must register the multicast source with theRendezvous Point (RP). This registration involves encapsulating the multicast packets in unicast messages and sending them to the RP.
This encapsulation is done over adynamically created tunnel interface, typically referred to as aPIM Register Tunnel. This temporary tunnel is established by the source-side router to send encapsulated multicast traffic to the RP for initial source registration.
Therefore, the dynamic tunnel serves the purpose of:
Encapsulating and sending the first multicast packets from the source to the RP Allowing the RP to learn about new sources and initiate shared tree or shortest-path tree forwarding This operation aligns with CCDE v3.1 design principles, where understanding the internal operation of multicast protocols-especially source registration and RP role-is critical for scalable and reliable multicast service delivery.
Why other options are incorrect:
A: First-hop router doesn't register itself, it registers thesourceto the RP.
B: Clients (receivers) do not register to the RP; they send IGMP/MLD joins which flow toward the RP.
D: Not all IPv6 multicast traffic is transported via tunnels; only initial registration traffic is encapsulated in this manner.
This mechanism is essential for source discovery in sparse-mode multicast and is foundational to multicast tree building in IPv6 networks.
