Q1. Which four services does the architecture for Media Services contain? (Choose four.)

A. access services

B. transport services

C. storage services

D. forwarding services

E. session control services

F. security services

G. filtering services

H. remote access services

Answer: A,B,C,E

Explanation:

An architecture framework for media services supports different models of video models. As shown in Figure 14-13, the network provides service to video media in the Media Services Framework. Those services are access services, transport services, bridging services, storage servers, and session control services, which arc provided to endpoints.

Access services provide identity of end devices, mobility, and location services.

Transport services provide QoS for reliable packet delivery.

Bridging services provide transcoding, conferencing, and recording services of media streams.

Storage services provide capture and storage of media streams and content management and distribution.

Session control services provide session signaling and control and gateway services.

Q2. The enterprise campus core layer has requirements that are unique from the distribution and access layers. Which of the following is true about the core layer?

A. The core layer provides convergence using Layer 2 and Layer 3 services and features.

B. The core layer provides high availability to support the distribution layer connections to the enterprise edge.

C. The campus core layer is optional.

D. The core layer requires high performance to manage the traffic policing across the backbone.

Answer: B

Q3. Which WLC interface is dedicated for WLAN client data?

A. virtual interface B. dynamic interface

C. management interface

D. AP manager interface

E. service port interface

Answer: B

Explanation:

WLC Interface Types

A WLC has five interface types:

Management interface (static, configured at setup, mandatory) is used for in-band management, connectivity to AAA, and Layer 2 discovery and association.

Service-port interface (static, configured at setup, optional) is used for out-of-band management. It is an optional interface that is statically configured.

AP manager interface (static, configured at setup, mandatory except for 5508 WLC) is used for Layer 3 discovery and association. It has the source IP address of the AP that is statically configured.

Dynamic interface (dynamic) is analogous to VLANs and is designated for WLAN client data.

Virtual interface (static, configured at setup, mandatory) is used for leaver 3 security authentication, DHCP relay support, and mobility management.

Q4. Which two statements about designing the Data Center Access layer are correct? (Choose two.)

A. Multiport NIC servers should each have their own IP address.

B. Layer 3 connectivity should never be used in the access layer.

C. Layer 2 connectivity is primarily implemented in the access layer.

D. Multiport NIC servers should never be used in the access layer.

E. Layer 2 clustering implementation requires servers to be Layer 2 adjacent.

Answer: C,E

Explanation:

User access is primarily layer 2 in nature, layer 2 clustering is possible only in layer 2 Here is the Explanation: from the Cisco press CCDA certification guide Figure 4-8. Enterprise Data Center Infrastructure Overview

Defining the DC Access Layer

The data center access layer’s main purpose is to provide Layer 2 and Layer 3 physical port density for various servers in the data center. In addition, data center access layer switches provide high-performance, low-latency switching and can support a mix of oversubscription requirements. Both Layer 2 and Layer 3 access (also called routed access) designs are available, but most data center access layers are built using Layer 2 connectivity. The Layer 2 access design uses VLAN trunks upstream, which allows data center aggregation services to be shared across the same VLAN and across multiple switches. Other advantages of Layer 2 access are support for NIC teaming and server clustering that requires network connections to be Layer 2 adjacent or on the same VLAN with one another.
