CompTIA Network+ (N10-007) — Question 218

As part of a transition from a static to a dynamic routing protocol on an organization's internal network, the routing protocol must support IPv4 and VLSM. Based on those requirements, which of the following should the network administrator use? (Choose two.)

Answer options

• A. OSPF
• B. IS-IS
• C. RIPv1
• D. BGP
• E. VRRP

Correct answer: A, B

Explanation

OSPF and IS-IS are both dynamic routing protocols that support IPv4 and Variable Length Subnet Masking (VLSM), making them suitable for this scenario. In contrast, RIPv1 does not support VLSM, while BGP and VRRP serve different purposes and are not primarily routing protocols used for internal networks in this context.
