Q1. - (Topic 5)

How does a DHCP server dynamically assign IP addresses to hosts?

A. Addresses are permanently assigned so that the host uses the same address at all times.

B. Addresses are assigned for a fixed period of time. At the end of the period, a new request for an address must be made, and another address is then assigned.

C. Addresses are leased to hosts. A host will usually keep the same address by periodically contacting the DHCP server to renew the lease.

D. Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.

Answer: C

Explanation:

DHCP works in a client/server mode and operates like any other client/server relationship. When a PC connects to a DHCP server, the server assigns or leases an IP address to that PC. The PC connects to the network with that leased IP address until the lease expires. The host must contact the DHCP server periodically to extend the lease. This lease mechanism ensures that hosts that move or power off do not hold onto addresses that they do not need. The DHCP server returns these addresses to the address pool and reallocates them as necessary.

Q2. - (Topic 7)

Scenario

Refer to the topology. Your company has connected the routers R1, R2, and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.

The EIGRP routing protocol is configured.

You are required to troubleshoot and resolve the EIGRP issues between the various routers.

Use the appropriate show commands to troubleshoot the issues.

The loopback interfaces on R4 with the IP addresses of 10.4.4.4/32, 10.4.4.5/32, and 10.4.4.6/32 are not appearing in the routing table of R5. Why are the interfaces missing?

A. The interfaces are shutdown, so they are not being advertised.

B. R4 has been incorrectly configured to be in another AS, so it does not peer with R5.

C. Automatic summarization is enabled, so only the 10.0.0.0 network is displayed.

D. The loopback addresses haven't been advertised, and the network command is missing on R4.

Answer: B

Explanation:

For an EIGRP neighbor to form, the following must match:

- Neighbors must be in the same subnet

- K values

- AS numbers

- Authentication method and key strings

Here, we see that R4 is configured for EIGRP AS 2, when it should be AS 1.

Topic 8, Mixed Questions

316. - (Topic 8)

Two hosts are attached to a switch with the default configuration. Which statement about the configuration is true?

A. IP routing must be enabled to allow the two hosts to communicate.

B. The two hosts are in the same broadcast domain.

C. The switch must be configured with a VLAN to allow the two hosts to communicate.

D. Port security prevents the hosts from connecting to the switch.

Q3. - (Topic 5)

Which statement describes VRRP object tracking?

A. It monitors traffic flow and link utilization.

B. It ensures the best VRRP router is the virtual router master for the group.

C. It causes traffic to dynamically move to higher bandwidth links.

D. It thwarts man-in-the-middle attacks.

Answer: B

Explanation:

Object tracking is the process of tracking the state of a configured object and uses that state to determine the priority of the VRRP router in a VRRP group.

Q4. - (Topic 7)

Which router IOS commands can be used to troubleshoot LAN connectivity problems? (Choose three.)

A. ping

B. tracert

C. ipconfig

D. show ip route

E. winipcfg

F. show interfaces

Answer: A,D,F

Explanation:

Ping, show ip route, and show interfaces are all valid troubleshooting IOS commands. Tracert, ipconfig, and winipcfg are PC commands, not IOS.

Q5. - (Topic 8)

On which type of port can switches interconnect for multi-VLAN communication?

A. interface port

B. access port

C. switch port

D. trunk port

Answer: D

Q6. - (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:

Since static routing is a manual process, it can be argued that it is more secure (and more prone to human errors) since the network administrator will need to make changes to the routing table directly. Also, in stub networks where there is only a single uplink connection, the load is reduced as stub routers just need a single static default route, instead of many routes that all have the same next hop IP address.

Q7. - (Topic 5)

Which of these represents an IPv6 link-local address?

A. FE80::380e:611a:e14f:3d69

B. FE81::280f:512b:e14f:3d69

C. FEFE:0345:5f1b::e14d:3d69

D. FE08::280e:611:a:f14f:3d69

Answer: A

Explanation:

In the Internet Protocol Version 6 (IPv6), the address block fe80::/10 has been reserved for link-local unicast addressing. The actual link local addresses are assigned with the prefix fe80::/64. They may be assigned by automatic (stateless) or stateful (e.g. manual) mechanisms.

Q8. - (Topic 8)

Which command can you enter to determine whether a switch is operating in trunking mode?

A. show ip interface brief

B. show vlan

C. show interfaces

D. show interface switchport

Answer: D

Q9. - (Topic 8)

Which MTU size can cause a baby giant error?

A. 1500

B. 9216

C. 1600

D. 1518

Answer: C

Q10. - (Topic 5)

What are three components that comprise the SNMP framework? (Choose three.)

A. MIB

B. agent

C. set

D. AES

E. supervisor

F. manager

Answer: A,B,F

Explanation:

The SNMP framework consists of three parts:

•An SNMP manager — The system used to control and monitor the activities of network devices using SNMP.

•An SNMP agent — The software component within the managed device that maintains the data for the device and reports these data, as needed, to managing systems. Cisco Nexus 1000V supports the agent and MIB. To enable the SNMP agent, you must define the relationship between the manager and the agent.

•A managed information base (MIB) — The collection of managed objects on the SNMP agent.

SNMP is defined in RFCs 3411 to 3418.
