Question No : 1  - (Topic 1)
 
Which option describes how a switch in rapid PVST+ mode responds to a topology
change?
 
 
A. It immediately deletes dynamic MAC addresses that were learned by all ports on the
switch. 
B. It sets a timer to delete all MAC addresses that were learned dynamically by ports in the
same STP instance. 
C. It sets a timer to delete dynamic MAC addresses that were learned by all ports on the
switch. 
D. It immediately deletes all MAC addresses that were learned dynamically by ports in the
same STP instance. 
 
Answer: D
Explanation:  
Rapid PVST+This spanning-tree mode is the same as PVST+ except that is uses a rapid
convergence based on the IEEE 802.1w standard. To provide rapid convergence, the rapid
PVST+ immediately deletes dynamically learned MAC address entries on a per-port basis
upon receiving a topology change. By contrast, PVST+ uses a short aging time for
dynamically learned MAC address entries. 
The rapid PVST+ uses the same configuration as PVST+ (except where noted), and the
switch needs only minimal extra configuration. The benefit of rapid PVST+ is that you can
migrate a large PVST+ install base to rapid PVST+ without having to learn the complexities
of the MSTP configuration and without having to reprovision your network. In rapid-PVST+
mode, each VLAN runs its own spanning-tree instance up to the maximum supported.

802.11
 
802.1w
 
802.1x
 
 
 
Answer: D 
Explanation:  
802.1X authentication involves three parties: a supplicant, an authenticator, and an
authentication server. The supplicant is a client device (such as a laptop) that wishes to
attach to the LAN/WLAN. The term 'supplicant' is also used interchangeably to refer to the
software running on the client that provides credentials to the authenticator. The
authenticator is a network device, such as an Ethernet switch or wireless access point;
and the authentication server is typically a host running software supporting the RADIUS
and EAP protocols. 
The authenticator acts like a security guard to a protected network. The supplicant (i.e.,
client device) is not allowed access through the authenticator to the protected side of the
network until the supplicant’s identity has been validated and authorized. An analogy to this
is providing a valid visa at the airport's arrival immigration before being allowed to enter the
country. With 802.1X port-based authentication, the supplicant provides credentials, such
as user name/password or digital certificate, to the authenticator, and the authenticator
forwards the credentials to the authentication server for verification. If the authentication
server determines the credentials are valid, the supplicant (client device) is allowed to
access resources located on the protected side of the network.

Question No : 4  - (Topic 3)
Which two are advantages of static routing when compared to dynamic routing? (Choose
two.)
 
 
A. Configuration complexity decreases as network size increases. 
B. Security increases because only the network administrator may change the routing
table. 
C. Route summarization is computed automatically by the router. 
D. Routing tables adapt automatically to topology changes. 
E. An efficient algorithm is used to build routing tables, using automatic updates. 
F. Routing updates are automatically sent to neighbors. 
G. Routing traffic load is reduced when used in stub network links. 
 
Answer: B,G
Explanation:  
When reading (or being lectured about) all the glorious details of dynamic routing protocols,
it's hard not to come away with the impression that dynamic routing is always better than
static routing. It's important to keep in mind that the primary duty of a dynamic routing
protocol is to automatically detect and adapt to topological changes in the internetwork.
The price of this "automation" is paid in bandwidth, security, and maybe queue space, in
memory, and in processing time. 
A frequent objection to static routing is that it is hard to administer. This criticism may be
true of medium to large topologies with many alternative routes, but it is certainly not true of

small internetworks with few or no alternative routes.

Cisco 200-105 : Braindumps Questions
Answer: A
Explanation:  
 
Router_E learns two subnets subnets 208.149.23.64 and 208.149.23.96 via Router_A
through FastEthernet interface. The interface cost is calculated with the formula 108 /
Bandwidth. For FastEthernet it is 108 / 100 Mbps = 108 / 100,000,000 = 1. Therefore the
cost is 12 (learned from Router_A) + 1 = 13 for both subnets - B is not correct. 
The cost through T1 link is much higher than through T3 link (T1 cost = 108 / 1.544 Mbps =
64; T3 cost = 108 / 45 Mbps = 2) so surely OSPF will choose the path through T3 link ->
Router_E will choose the path from Router_A through FastEthernet0/0, not Serial1/0 - C &
D are not correct. 
In fact, we can quickly eliminate answers B, C and D because they contain at least one
subnet learned from Serial1/0 - they are surely incorrect.

Assume that all of the router interfaces are operational and configured correctly. How will
router R2 be affected by the configuration of R1 that is shown in the exhibit?
 
 
A. Router R2 will not form a neighbor relationship with R1. 
B. Router R2 will obtain a full routing table, including a default route, from R1. 
C. R2 will obtain OSPF updates from R1, but will not obtain a default route from R1.

Cisco 200-105 : Braindumps Questions
D. R2 will not have a route for the directly connected serial network, but all other directly
connected networks will be present, as well as the two Ethernet networks connected to R1. 
 
Answer: A
Explanation:  
Open Shortest Path First 
http://en.wikipedia.org/wiki/Open_Shortest_Path_First 
 
The configuration of R1 shows "router ospf 1" however, the diagram also shows that both
routers should be in the backbone OSPF Area of "0". When routers are in different OSPF
areas they will not form a neighbor relationship. 
Neighbor relationships 
As a link state routing protocol, OSPF establishes and maintains neighbor relationships in
order to exchange routing updates with other routers. The neighbor relationship table is
called an adjacency database in OSPF. 
Provided that OSPF is configured correctly, OSPF forms neighbor relationships only with
the routers directly connected to it. In order to form a neighbor relationship between two
routers, the interfaces used to form the relationship must be in the same area. Generally an
interface is only configured in a single area, however you can configure an interface to
belong to multiple areas. In the second area, such an interface must be configured as a
secondary interface. (A neighbor state simulation shows how neighbor state changes from
Down to Full Adjacency progressively with exchanging Hello, DD, Request, Update, and
Ack packets).

Question No : 9  - (Topic 4)
Which Layer 2 protocol encapsulation type supports synchronous and asynchronous
circuits and has built-in security mechanisms?
 
 
A. HDLC 
B. PPP 
C. X.25 
D. Frame Relay 
 
Answer: B
Explanation:  
High-Level Data Link Control (HDLC) - HDLC is the default encapsulation type on point-to-
point, dedicated links, and circuit-switched connections. It is used typically when
communicating between two Cisco devices. It is a bit-oriented synchronous data link layer
protocol. 
Point-to-Point Protocol (PPP) - Provides router-to-router and host-to network connections
over synchronous and asynchronous circuits. PPP was designed to work with several
network layer protocols, such as IP, and IPX. PPP also has built in security mechanisms
such as PAP and CHAP X.25/Link Access Procedure, Balanced (LAPB) - ITU-T standard
that defines how connections between DTE and DCE are maintained for remote terminal
access and computer communications in public data networks. X.25 specifies LAPB, a data
line layer protocol. X.25 is a predecessor to Frame Relay. 
Frame Relay - Industry standard, switched data link layer protocol that handles multiple
virtual circuits. It is a next-generation to X.25 that is streamlined to eliminate some of the
time-consuming processes (such as error correction and flow control) that were employed
