8.
B. Each port on a switch is a separate collision or bandwidth domain. All ports on a
hub share the same bandwidth domain.
Q&A
1.
False. Layer 2 switches limit only the collision domain.

Inter-Switch Link (ISL) and IEEE 802.1p/802.1Q
6.
A. IP phone-to-IP phone communication is an example of peer-to-peer communica-
tion.
7.
A, C, and E. Network applications, infrastructure devices, and environmental charac-
teristics affect network design.
8.
C. Multimode fiber provides the necessary connectivity at the required distance. UTP
can reach only 100 m. Single-mode fiber is more expensive.
9.
B. The DC aggregation layer is similar to the campus distribution layer.
10.
C. Disabling trunking on host ports and using RPVST+ are best practices at the access
layer.
11.
B. The use of HSRP and summarization of routes are best practices in the distribution
layer.
12.
A. Best practices for the core is the use of triangle connections to reduce switch peer-
ing and use routing to prevent network loops.
13.
D. Load balancers, SSL offloading, firewalls, and intrusion detection devices are
deployed in the DC aggregation layer.
14.
D. All are threats to the enterprise edge distribution.
15.
C. Create a server farm that allows the enforcement of security policies.
16.
B. These are design considerations for the distribution layer.
17.
D. All are server connectivity options.
18.
A. The core and the distribution should be connected using redundant Layer 3 trian-
gular links.
19.
B. The building subnets are too large and should be further segmented to reduce the
broadcast domain.
20.
B. Broadcasts are not forwarded by routers and are controlled by VLANs.
