A network administrator checks this adjacency table on a router. What is a possible cause for the
incomplete marking?

A.
incomplete ARP information

B.
incorrect ACL

C.
dynamic routing protocol failure

D.
serial link congestion

Answer: A
Explanation:

To display information about the Cisco Express Forwarding adjacency table or the hardware Layer
3-switching adjacency table, use the show adjacency command.

Reasons for Incomplete Adjacencies

There are two known reasons for an incomplete adjacency:

No ARP Entry

When CEF cannot locate a valid adjacency for a destination prefix, it punts the packets to the CPU
for ARP resolution and, in turn, for completion of the adjacency.

C.
latency

D.
windowing

E.
lower throughput

Answer: A,C,E
Explanation:

It is a general best practice not to mix TCP-based traffic with UDP-based traffic (especially
streaming video) within a single service provider class due to the behaviors of these protocols
during periods of congestion. Specifically, TCP transmitters will throttle-back flows when drops
have been detected. Although some UDP applications have application-level windowing, flow
control, and retransmission capabilities, most UDP transmitters are completely oblivious to drops
and thus never lower transmission rates due to dropping. When TCP flows are combined with
UDP flows in a single service provider class and the class experiences congestion, then TCP
flows will continually lower their rates, potentially giving up their bandwidth to drop-oblivious UDP
flows. This effect is called TCP-starvation/UDP-dominance. This can increase latency and lower
the overall throughput.

TCP-starvation/UDP-dominance likely occurs if (TCP-based) mission-critical data is assigned to
the same service provider class as (UDP-based) streaming video and the class experiences
sustained congestion. Even if WRED is enabled on the service provider class, the same behavior
would be observed, as WRED (for the most part) only affects TCP-based flows.

Granted, it is not always possible to separate TCP-based flows from UDP-based flows, but it is
beneficial to be aware of this behavior when making such application-mixing decisions.

QUESTION NO: 5

Which method allows IPv4 and IPv6 to work together without requiring both to be used for a single
connection during the migration process?

A.
dual-stack method

B.
6to4 tunneling

"Pass Any Exam. Any Time." - www.actualtests.com 5

Cisco 300-101 Exam
C.
GRE tunneling

D.
NAT-PT

Answer: A
Explanation:

Dual stack means that devices are able to run IPv4 and IPv6 in parallel. It allows hosts to
simultaneously reach IPv4 and IPv6 content, so it offers a very flexible coexistence strategy. For
sessions that support IPv6, IPv6 is used on a dual stack endpoint. If both endpoints support Ipv4
only, then IPv4 is used.

Benefits:

• Native dual stack does not require any tunneling mechanisms on internal networks

• Both IPv4 and IPv6 run independent of each other

• Dual stack supports gradual migration of endpoints, networks, and applications.

Reference: http://www.cisco.com/web/strategy/docs/gov/IPV6at_a_glance_c45-625859.pdf

QUESTION NO: 6

Which statement about the use of tunneling to migrate to IPv6 is true?

A.
Tunneling is less secure than dual stack or translation.

B.
Tunneling is more difficult to configure than dual stack or translation.

C.
Tunneling does not enable users of the new protocol to communicate with users of the old protocol
without dual-stack hosts.

D.
Tunneling destinations are manually determined by the IPv4 address in the low-order 32 bits of
IPv4-compatible IPv6 addresses.

Answer: C

"Pass Any Exam. Any Time." - www.actualtests.com 6

Cisco 300-101 Exam
Explanation:

Using the tunneling option, organizations build an overlay network that tunnels one protocol over
the other by encapsulating IPv6 packets within IPv4 packets and IPv4 packets within IPv6
packets. The advantage of this approach is that the new protocol can work without disturbing the
old protocol, thus providing connectivity between users of the new protocol.

Tunneling has two disadvantages, as discussed in RFC 6144:

• Users of the new architecture cannot use the services of the underlying infrastructure.

• Tunneling does not enable users of the new protocol to communicate with users of the
old protocol without dual-stack hosts, which negates interoperability.

A user is having issues accessing file shares on a network. The network engineer advises the user
to open a web browser, input a prescribed IP address, and follow the instructions. After doing this,
the user is able to access company shares. Which type of remote access did the engineer enable?

A.
EZVPN

B.
Ipsec VPN client access

C.
VPDN client access

D.
SSL VPN client access

Answer: D
Explanation:

The Cisco AnyConnect VPN Client provides secure SSL connections to the security appliance for
remote users. Without a previously installed client, remote users enter the IP address in their
browser of an interface configured to accept SSL VPN connections. Unless the security appliance
is configured to redirect http:// requests to https://, users must enter the URL in the form
https://<address>.

After entering the URL, the browser connects to that interface and displays the login screen. If the
user satisfies the login and authentication, and the security appliance identifies the user as
requiring the client, it downloads the client that matches the operating system of the remote
computer. After downloading, the client installs and configures itself, establishes a secure SSL
connection and either remains or uninstalls itself (depending on the security appliance
configuration) when the connection terminates.

Answer: B
Explanation:

Dynamic Multipoint Virtual Private Network (DMVPN) is a dynamic tunneling form of a virtual
private network (VPN) supported on Cisco IOS-based routers and Unix-like Operating Systems
based on the standard protocols, GRE, NHRP and Ipsec. This DMVPN provides the capability for
creating a dynamic-mesh VPN network without having to pre-configure (static) all possible tunnel
end-point peers, including Ipsec (Internet Protocol Security) and ISAKMP (Internet Security
Association and Key Management Protocol) peers. DMVPN is initially configured to build out a
hub-and-spoke network by statically configuring the hubs (VPN headends) on the spokes, no
change in the configuration on the hub is required to accept new spokes. Using this initial hub-
and-spoke network, tunnels between spokes can be dynamically built on demand (dynamic-mesh)
without additional configuration on the hubs or spokes. This dynamic-mesh capability alleviates
the need for any load on the hub to route data between the spoke networks.

DMVPN is combination of the following technologies:

C.
only ssh traffic to vty 0 4 from source 2001:DB8:0:4::32

D.
all traffic to vty 0 4 from source all

Answer: C
Explanation:

Here we see that the Ipv6 access list called “cisco” is being applied to incoming VTY connections
to the router. Ipv6 access list has just one entry, which allows only the single Ipv6 IP address of
2001:DB8:0:4::32 to connect using SSH only.

B.
You can use the KRON scheduler.

C.
You can use an extended access list.

D.
You can use an IOS parser.

E.
You can use the RITE traffic exporter.

Refer to the following access list.

Access-list 100 permit ip any any log

After applying the access list on a Cisco router, the network engineer notices that the router CPU
utilization has risen to 99 percent. What is the reason for this?

A.
A packet that matches access-list with the “log” keyword is Cisco Express Forwarding switched.

B.
A packet that matches access-list with the "log" keyword is fast switched.

C.
A packet that matches access-list with the "log" keyword is process switched.

D.
A large amount of IP traffic is being permitted on the router.

Answer: C
Explanation:

ging-enabled access control lists (ACLs) provide insight into traffic as it traverses the network or is
dropped by network devices. Unfortunately, ACL logging can be CPU intensive and can negatively
affect other functions of the network device. There are two primary factors that contribute to the
CPU load increase from ACL logging: process switching of packets that match log-enabled access
control entries (ACEs) and the generation and transmission of log messages.

Care must be taken to ensure that the appropriate Unicast RPF mode (loose or strict) is configured during the deployment of this feature because it can drop legitimate traffic. Additionally. Dropping this legitimate traffic could occur when asymmetric routing paths are present in the network. This security feature works by enabling a router to verify the reachability of the source address in packets being forwarded. This capability can limit the appearance of spoofed addresses on a network. Administrators can change this behavior using the allow-default option. Unicast RPF configured in strict mode may drop legitimate traffic that is received on an interface that was not the router's choice for sending return traffic.
