QUESTION 11
Refer to the exhibit.
Model A is the recommended design for routing between Building Distribution switches and Campus Core switches. Which two statements describe the reasons? (Choose two)
A. Model A uses timer-based non-deterministic convergence.
B. Mode A uses timer-based, providing fast convergence to the remaining path.
C. In Model A, a link or box failure does not require routing protocol convergence.
D. In Model A, the Layer 3 redundant equal cost links support fast convergence.
Correct Answer: CD
Section: Architecture Explanation
Due to redundant links in place the routing protocols can select multiple equal cost paths and installs them as soon as one of the links goes down, such topology also can support load-balancing.

QUESTION 12
Which one of these statements is true concerning the enterprise data center?
A. It can be located either at the enterprise campus or at a remote branch.
B. Remote data center connectivity requirements align with the small office design.
C. The data center designs will differ substantially depending on whether the location is on campus or remote.
D. A remote branch with a data center becomes the enterprise campus.
Correct Answer: C
Section: Data Center Explanation
If data center is at enterprise campus there will be no need for installing high capacity WAN links, just an upgrade if existing WAN infrastructure can accommodate increased traffic demands. There are many more such considerations while designing data centers.

QUESTION 13
Which Cisco security management solution provides the means to identify, isolate, and counter security threats to the network?
A. Adaptive Security Device Manager
B. Intrusion Prevention Device Manager
C. Security Device Manager
D. Cisco Security Manager
E. Cisco Security Monitoring, Analysis, and Response System
Correct Answer: E
Section: Security Explanation
Cisco Security MARS is a security threat mitigation (STM) system. It delivers a range of information about your networks’ health as reported by devices in your network. Cisco Security Monitoring, Analysis, and Response System (Cisco Security MARS) is an appliance-based solution for network security administrators to monitor, identify, isolate, and respond to security threats. MARS understands the network topology and device congurations from routers, switches, rewalls, and IPS devices. MARS also can model packet ows on the network.
Note: Cisco has a variety of security management products and technologies that allow scalable administration and enforcement of security policy for the Cisco SCF architecture. These solutions reduce the operational management and automate many of the common tasks, including configuration, analysis, incident response, and reporting. Security management platforms include the following.

QUESTION 14
A global corporation has an internal network with the following characteristics:
-2,000,000+ hosts
-10,000 + routers
-Internal connectivity
-high traffic volumes with business partners and customers
Which statement best describes what a flexible IPv6 strategy would look like for this corporation?
A. Both hosts and routers would run dual stack
B. Hosts would run IPv4 and routers would run native IPv6
C. Hosts would run dual stack and routers would run IPv4 only
D. Hosts would run IPv6 and routers would run native IPv6
Correct Answer: A
Section: IP addressing Explanation
Dual-stack is the preferred, most versatile way to deploy IPv6 in existing IPv4 environments. IPv6 can be enabled wherever IPv4 is enabled along with the associated features required to make IPv6 routable, highly available, and secure. In some cases, IPv6 is not enabled on a specific interface or device because of the presence of legacy applications or hosts for which IPv6 is not supported. Inversely, IPv6 may be enabled on interfaces and devices for which IPv4 support is no longer needed.

QUESTION 15
Which of these is the best routing deployment for a single dedicated link to an ISP for Internet access?
A. EIGRP
B. RIP
C. BGP
D. Static
E. OSPF
Correct Answer: D
Section: Routing Explanation
Static routing reduces the complexity and is best way of routing when there are no redundant paths to be maintained.
