Cisco Designing Cisco Enterprise Networks Sample Questions (Q262-Q267):

NEW QUESTION # 262
A company is running BGP on a single router, which has two connections to the same ISP. Which BGP feature ensures traffic is load balanced across the two links to the ISP?

A. Multipath Load Sharing
B. AS-Path Prepending
C. Next-Hop Address Tracking
D. Multihop

Answer: A

Explanation:
BGP Multipath Load Sharing for eBGP and iBGP allows you to configure multipath load balancing with both eBGP and iBGP paths in BGP networks that are configured to use MPLS.

NEW QUESTION # 263
Which two Cisco ISE use cases typically involve the highest level of implementation complexity?
(Choose two.)

A. Software-defined access
B. Guest and wireless access
C. Software-defined segmentation
D. Asset visibility
E. Device management

Answer: A,C

NEW QUESTION # 264
Which two activities should occur during an SE's discovery process? (Choose two.)

A. Working with the customer to develop a reference architecture
B. Mapping Cisco innovation to customer s needs
C. Establishing credibility with the customer
D. Gathering information about the current state of the customer s network environment
E. Referencing the PPDIOO model to effectively facilitate the discussion

Answer: C,D

NEW QUESTION # 265
Refer to the exhibit.

An architect is designing a network for a customer supporting a Wake-on-LAN application. Which solution must the architect choose?

A. IP directed-broadcasts on R1
B. spanning-tree uplinkfast on SW1
C. IP directed-broadcasts on R2
D. spanning-tree uplinkfast on SW2

Answer: C

Explanation:
Explanation
"IP directed broadcast" must be supported on the last router to the destination subnet. Since the sleeping PC's dont have IP adresses, the machines must be calles awake by broadcast that behaves like an unicast untill they reach the destination network. There the directed broadcast is handled like a proper broadcast to wake all WOL machines.

NEW QUESTION # 266
A network engineer must connect two sites across a public network using a secure tunneling technology that supports multicast traffic. Which technology must be chosen?

A. IPsec
B. GRE
C. PPTP
D. GRE over IPsec

Answer: D

Explanation:
GRE over IPsec is the correct secure tunneling choice when multicast traffic must cross a public network.
Native IPsec protects unicast IP traffic, but it does not inherently carry multicast routing protocols or multicast application flows in the same way that GRE can. GRE creates a logical point-to-point tunnel that can encapsulate multicast, broadcast, and non-IP payloads; IPsec then encrypts the GRE packet for confidentiality and integrity across the untrusted transport. Cisco designs commonly use this combination when dynamic routing protocols, multicast applications, or other non-unicast traffic must be transported securely between sites. GRE by itself supports multicast, but it does not provide encryption, so it fails the secure tunneling requirement. PPTP is obsolete and not appropriate for modern enterprise design. Plain IPsec is secure, but it is not the complete answer when multicast support is explicitly required. Therefore, the design should use GRE over IPsec: GRE supplies the multicast-capable overlay, and IPsec supplies the cryptographic protection across the public network.
