B.

Layer 2

C.

Layer 3

B.

AutoQoS

C.

NetFlow

QUESTION 163

A campus network utilizes EIGRP to connect to several remote branch offices. Which configuration should be established on all branch routers to improve routing scalability and performance?

 

A.

Configure authentication between the campus and branch offices.

B.

Enable stub routing on all branch routers.

C.

Adjust EIGRP k-values to utilize delay.

D.

Utilize offset lists to direct traffic more efficiently.

 

Correct Answer: B

 

 

QUESTION 164

Which unique characteristics of the Data Center Aggregation layer must be considered by an Enterprise Campus designer?

 

A.

Layer 3 routing between the Access and Aggregation layers facilitates the ability to span VLANs across multiple access switches, which is a requirement for many server virtualization and clustering technologies.

B.

“East-west” server-to-server traffic can travel between aggregation modules by way of the core, but backup and replication traffic typically remains within an aggregation module.

C.

Load balancing, firewall services, and other network services are commonly integrated by the use of service modules that are inserted in the aggregation switches.

D.

Virtualization tools allow a cost effective approach for redundancy in the network design by using two or four VDCs from the same physical switch.

 

Correct Answer: C

 

 

QUESTION 165

Which technology allows centralized storage services to be shared across different VSANs?

 

A.

IVR

B.

FSPF

C.

FICON

D.

SANTap

 

Correct Answer: A

Explanation:

IVR = InterVSAN Routing

 

 

QUESTION 166

What are two characteristics of Cisco Global Site Selector? (Choose two.)

 

A.

It helps verify end-to-end path availability.

B.

It provides traffic rerouting in case of disaster.

C.

HSRP, GLBP, and VRRP can be clients of GSS.

D.

BGP must be the routing protocol between the distributed data centers.

E.

DNS responsiveness is improved by providing centralized domain management.

 

Correct Answer: BE

 

 

QUESTION 167

An engineer is designing a QoS architecture for a small organization and must meet these requirements:

 

clip_image002Guarantees resources for a new traffic flow prior to sending

clip_image002[1]Polices traffic when the flow does not conform

 

Which QoS architecture model will accomplish this?

 

A.

auto quality of service

B.

modular quality of service

C.

differentiated services

D.

integrated services

 

Correct Answer: D

 

 

QUESTION 168

What network storage protocol uses a connection standard incompatible with shared 10Gb Ethernet physical connection?

 

A.

SMB

B.

iSCSI

C.

FC

D.

NFS

E.

CIFS

 

Correct Answer: C

 

 

 

 

QUESTION 169

Which two elements comprise the backbone area while designing a new network utilizing IS-IS as the interior gateway protocol? (Choose two)

 

A.

contiguous chain of Level 2 capable routers

B.

contiguous chain of Level1/Level 2 capable routers

C.

set of Level 2 configured interfaces

D.

contiguous Level 1 capable routers

E.

set of Level 1 configured interfaces

 

Correct Answer: AB

Explanation:

https://www.cisco.com/en/US/products/ps6599/products_white_paper09186a00800a3e6f.shtml

 

“Backbone IS-IS does not have a backbone area like the OSPF area 0. The IS-IS backbone is a contiguous collection of Level 2-capable routers, each of which can be in a different area”

 

http://www.ciscopress.com/articles/article.asp?p=26850&seqNum=3

 

“In most designs with routing hierarchy, the Level 2 routers are also Level 1 routers by virtue of their identification with a certain area. Therefore, in IS-IS, a router can function as Level 1-only or Level 2-only and possibly as both Level 1 and Level 2 (Level 1-2). Level 1-2 routers act as border routers to their respective areas, providing connectivity to other areas. The Level 2 backbone is essentially a virtual IS-IS area consisting of routers engaged in Level 2 routing”

 

 

QUESTION 170

Which two technologies provide web and URL filtering and mitigate zero-day malware? (Choose two)

 

A.

Cisco CWS

B.

Cisco WSA

C.

Cisco GETVPN

D.

Cisco ESA

E.

NAT/PAT

 

Correct Answer: AB
