NEW QUESTION 11
OSPF is configured using default classful addressing. With all routers and interfaces operational, how many networks will be in the routing table of R1 that are indicated to be learned by OSPF?
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
- F. 5
Answer: E
Explanation:
It already knows about its directly connected ones, only those not directly connected are "Learned by OSPF". OSPF as a link state routing protocol (deals with LSAs rather than routes) does not auto summarize (doesn't support "auto-summary").So learned route by OSPF are followed 172.16.2.64/26 172.16.2.228/30 172.16.2.232/30 172.16.3.0/24
NEW QUESTION 12
Refer to the exhibit.
Which two statements are true about the loopback address that is configured on RouterB? (Choose two.)
- A. It indicates that RouterB should be elected the DR for the LAN.
- B. It decreases the metric for routes that are advertised from RouterB.
- C. It provides stability for the OSPF process on Router
- D. It ensures that data will be forwarded by RouterB.
- E. It specifies that the router ID for RouterB should be 10.0.0.1.
Answer: C,E
Explanation:
A loopback interface never comes down even if the link is broken so it provides
stability for the OSPF process (for example we use that loopback interface as the router-id) - B is
correct.
The router-ID is chosen in the order below:
The highest IP address assigned to a loopback (logical) interface.If a loopback interface is not
defined, the highest IP address of all active router's physical interfaces will be chosen.
-The loopback interface will be chosen as the router ID of RouterB - C is correct.
NEW QUESTION 13
A spa wants to increase awareness of its package holiday deals internationally. It has been investing heavily in influencer marketing and social media campaigns. Its most popular influencer recently posted a video about the retreat that received 500,000 likes in the first day. The spa gained more than 3,000 new followers on its Instagram account.
Given the outcome of this organic post, the spa decides to pull their paid social media campaigns because this spend generates only a quarter of the engagement compared to influencer posts.
What advice should the analyst share about measuring success in this way?
- A. The spa should review the number of new followers at least one month later before pulling spend from paid campaigns.
- B. It is always better to diversify spend equally across multiple marketing strategies.
- C. Engagement metrics such as likes, comments and followers may not translate into incremental business value such as brand equity or sales.
- D. The spa should review the number of shares that the original post achieved before pulling spend from paid campaigns.
Answer: C

NEW QUESTION 18
Refer to the exhibit.
What is the meaning of the term dynamic as displayed in the output of the show frame-relay map command shown?
- A. The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned through Inverse ARP
- B. The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud
- C. The DLCI 100 was dynamically allocated by the router
- D. The Serial0/0 interface is passing traffic.
- E. The Serial0/0 interface acquired the IP address of 172.16.3.1 from a DHCP server
Answer: A
Explanation:
The term dynamic indicates that the DLCI number and the remote router IP address 172.16.3.1 are learned via the Inverse ARP process. Inverse ARP is a technique by which dynamic mappings are constructed in a network, allowing a device such as a router to locate the logical network address and associate it with a permanent virtual circuit (PVC).
NEW QUESTION 19
What are three characteristics of the OSPF routing protocol? (Choose three.)
- A. OSPF routers send the complete routing table to all directly attached routers.
- B. It uses the DUAL algorithm to determine the best route.
- C. OSPF routers discover neighbors before exchanging routing information.
- D. OSPF is a classful routing protocol.
- E. It uses cost to determine the best route.
- F. It converges quickly.
Answer: C,E,F
Explanation:
Open Shortest Path First Reference:
http://docwiki.cisco.com/wiki/Open_Shortest_Path_First
Explanation:
Additional OSPF features include equal-cost, multipath routing, and routing based on upper-layer type-ofservice
(TOS) requests. TOS-based routing supports those upper-layer protocols that can specify particular
types of service. An application, for example, might specify that certain data is urgent. If OSPF has high-priority
links at its disposal, these can be used to transport the urgent datagram.
OSPF supports one or more metrics. If only one metric is used, it is considered to be arbitrary, and TOS is not supported. If more than one metric is used, TOS is optionally supported through the use of a separate metric (and, therefore, a separate routing table) for each of the eight combinations created by the three IP TOS bits (the delay, throughput, and reliability bits). For example, if the IP TOS bits specify low delay, low throughput, and high reliability, OSPF calculates routes to all destinations based on this TOS designation. IP subnet masks are included with each advertised destination, enabling variable-length subnet masks. With variable-length subnet masks, an IP network can be broken into many subnets of various sizes. This provides network administrators with extra network-configuration flexibility.
NEW QUESTION 20

Refer to the exhibit.
Which statement describes DLCI 17?
- A. DLCI 17 describes a PVC on R2. It cannot be used on R3 or R1.
- B. DLCI 17 describes the ISDN circuit between R2 and R3.
- C. DLCI 17 describes the dial-up circuit from R2 and R3 to the service provider.
- D. DLCI 17 is the Layer 2 address used by R2 to describe a PVC to R3.
Answer: D
Explanation:
DLCI stands for Data Link Connection Identifier. DLCI values are used on Frame Relay interfaces to distinguish between different virtual circuits. DLCIs have local significance because, the identifier references the point between the local router and the local Frame Relay switch to which the DLCI is connected.

NEW QUESTION 27
Which protocol provides a method of sharing VLAN configuration information between two Cisco switches?
- A. 802.1Q
- B. RSTP
- C. VTP
- D. STP
Answer: C
Explanation:
Understanding VLAN Trunk Protocol (VTP) http://www.cisco.com/en/US/tech/tk389/tk689/technologies_tech_note09186a0080094c52.shtml
Introduction VLAN Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst series products.
