QUESTION 185
An architect must design an IPv6 migration solution for a corporation with remote offices to support:
* The customer has IPv4 peering with their service provider.
* IPv6 users need access to IPv4 and IPv6 resources.
* Existing content providers will migrate to IPv6 in the next two years.

QUESTION 186
When IPsec VPNs are designed, what is a unique requirement if support for IP Multicast is required?

QUESTION 187
Refer to the exhibit. A customer wants to adopt a dynamic site-to-site VPN solution to secure communication for VoIP, video, and FTP traffic between the remote branches and the headquarters. The customer also wants the branches to communicate directly, thereby reducing traffic at the headquarters location. The solution most consider that the branch routers are limited in available memory. Which VPN solution meets these requirements?

QUESTION 188
Which two best practices must be followed when designing an out-of-band management network? (Choose two.)

QUESTION 189
What two features are benefits of using GRE tunnels with IPsec over using an IPsec tunnel alone in building-to-building site-to-site VPNs? (Choose two.)

QUESTION 190
Refer to the exhibit.

Refer to the exhibit. An architect must create a stable and scalable EIGRP solution for a customer. The design must:
* conserve bandwidth, memory, and CPU processing
* prevent suboptimal routing
* avoid any unnecessary queries
Which two solutions must the architect select? (Choose two.)

QUESTION 191
Refer to the exhibit.

The failover time of ISP-2 is significantly shorter than ISP-1 when an interface on the ISP router toward the campus network fails. Which solution minimizes the downtime to the sub-second?

QUESTION 192
Drag and drop the characteristics from the left onto the YANG models they describe on the right. Not all options are used.

QUESTION 193
An engineer must peer with an ISP for internet connectivity using BGP, initially, the engineer wants to receive only specific prefixes from the ISP and a default route. However, the solution must provide the flexibility to add prefixes in the future at short notice. The ISP has a two-week change process in place. Which route filtering solution must the engineer employ?

QUESTION 194
A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive. However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?

QUESTION 195
An ISP provides Layer 3 VPN service over MPLS to a customer with four branches and multiple CE routers at each branch. To exchange the routes that are learned from the CE routers, which BGP address family should the ISP activate among the PE routers?

QUESTION 196
A company plans to transition to IPv6. They will link their IPv4 addresses to the lowest significant bits of the new Ipv6 addresses. A network administrator with an employee id: 4264:42:116 is preparing a mapping schema for the new IPv6 addresses. Which address does the
172.16.10.0/24 network translate to?

QUESTION 197
A customer has several remote sites connected with their headquarters through microwave links. An engineer must propose a backup WAN solution based on these conditions:

Which backup WAN link type the engineer recommend?

QUESTION 198
A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive. However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?

QUESTION 199

Refer to the exhibit. EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

QUESTION 200
A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup. Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?

QUESTION 201
Drag and drop the characteristics from the left onto the configuration protocols they describe on the right.
