Question: 1
|
How does the fact that the
business model is shifting to a more centralized and virtualized data center
impact branch office networks?
A. Because businesses are
shifting away from dedicated application servers running in the branch, branch
office network management is radically simplified.
B. Branch office networks have
very little security and compliance concerns because all company data is stored
and backed up at a centralized location with targeted security.
C. Branch office networks may
be farther from productivity enhancing network resources than they used to be,
creating delay when helping customers.
D. Because the data center is
composed of high-performance network devices with next-generation
traffic-prioritization capabilities, emerging voice and video applications will
run with ease in today's branch offices.
|
Answer: A
|
Explanation:
The main benefits of virtualization in the
branch office include:
* Lower infrastructure and
operating costs
* Less application downtime
and faster response time and failure recovery time
* Faster time to deployment
for applications
In summary, branch-office
server virtualization increases the speed of application deployment, improves
application uptime and performance guarantees, and reduces equipment and
operating costs.
In summary, the capability to
copy and restore the entire state of a virtual server to a specific point in
time improves the speed of recovery after a server failure, speeds up the
migration process to new server hardware, and helps enable faster rollback to a
fail-safe state in case of an unstable application.
Note: Branch-office infrastructure
has always been a source of challenge for IT departments. Some of these are
specific to the company's line of business, and others cut across all
industries. The cost of deploying new applications to remote locations, the
impact of insufficient environmental controls on equipment, security and
regulatory compliance constraints, the performance of centralized applications,
and support for critical uptime requirements are just a few examples. Further,
the challenges increase as the number of branch offices grows. According to a
2010 study by the Internet Research Group (IRG), in the past decade the number
of branch offices in the United States has grown by 21 percent.2 Although no
one product or technology can cure all of the current branch office headaches,
server virtualization does address some of the most difficult issues.
Incorrect answers:
D: Emerging voice and video
applications will require much more network bandwidth (not directly run with
ease).

Question: 2
|
A mid-sized business is
seeking a networking solution, and the customer is concerned about how the
components will work together from end to end now and in the future.
What message should the HP
sales professional deliver?
A. The customer must use the
same vendor from end to end to ensure interoperability; HP provides servers,
storage, and networking components.
B. The customer should
implement open standards wherever possible, and certainly at the boundaries of
each network segment to enable the company to select the best solutions for
each segment and have them interoperate
C. The customer should commit
to a single open-standard vendor, which implements with proven,
best-in-industry solutions.
D. The customer should select
solutions based on which provide the best proprietary protocols for the
company's highest priority business needs.
|
Answer: B
|
Explanation:
With an open, standards-based
solution, enterprises can migrate their networks from legacy architectures to
advanced architectures so they can meet contemporary business challenges,
including cloud computing, federated applications, virtual machine mobility,
high-performance mobile access, multimedia and video. Customers can choose
best-in-class solutions that will meet their business needs. Using open,
industry-standard protocol implementations mitigates the risk and cost of
change when the network needs to adapt to new business requirements. And using
open networks will make it simpler for enterprises move their applications to
public and private cloud services.

Question: 3
|
What is a typical struggle for
a company that has allowed its network management solution to grow organically?
A. The IT staff must use a
diverse set of management tools that do not integrate with each other.
B. The company has been locked
into a costly management solution as part of a package with a single vendor.
C. The company has a single management
solution, which does not fit the needs of some segments of the network.
D. The IT staff implements all
configuration and management manually without the help of any management tools.
|
Answer: A
|
Explanation:
A large network might begin as
a homogenous environment. Switches, routers, servers, and wireless access
points can all be from the same vendor and use the same network management
software. But as the network expands, it can get equipment from a variety of
manufacturers—each with its own set of network management tools. single
manufacturer might even have multiple versions of its network management
software. It’s this increasing network management complexity that bogs down IT.
A network manager may need to be proficient with several different management
tools to keep the enterprise up and running reliably.

Question: 4
|
For campus LANs, Gartner
predicts that one factor will push network capacity by as much as 10 times
current levels. What is this factor?
A. applications hosted in
private clouds
B. video
C. Voice over IP traffic
D. SANs
|
Answer: B
|
Explanation:
New video applications will
push network capacity needs by four to 10 times above current average levels.

Question: 5
|
What is a primary disadvantage
for companies that have committed to a single-vendor network?
A. The single-vendor network
often fails to provide advanced solutions because proprietary technologies so
often lag behind open-standard ones.
B. The components in the
single-vendor network fail to interoperate with each other well because they
use proprietary technologies.
C. The companies are limited
in their future choice of services and solutions based on whether their choices
work with that vendor's proprietary technologies.
D. The company cannot segment
the network well, which makes it more difficult for network designers to
implement an efficient, two-tier architecture.
|
Answer: D
|
Explanation:
Industry analysts predict that
these trends—service-oriented architectures, server virtualization, video and
collaboration, and widespread mobility—will bring a legacy network to a
breaking point if proactive steps are not taken to prepare. According to Gartner,
businesses that don’t segment their network infrastructure will suffer higher
costs and increased vendor lock-in.With this segmentation of functional
building blocks, businesses can
choose best-in-class solutions
that fit their needs, rather than being locked into a one-size-fits-all
solution. By using standard protocols at the boundaries, businesses can enable
interoperability among the network segments and gain both agility and scale.

Don’t Segment Their Network Infrastructure Will Have Higher Costs and Increased
Vendor Lock-in,” Tim Zimmerman, 15 March 2011.
